DROMEC Winches develops 3 electric winch systems

Ampelmann delivers safe and efficient offshore access solutions to the global offshore energy sector. Its portfolio of modular and energy efficient gangways is tailored to meet every local and global demand, providing reliable and consistent access to offshore installations in a variety of sea states and weather conditions. In collaboration with the engineers at DROMEC Winches, Ampelmann has developed 3 electric energy-efficient winch systems.

Energy Efficiency

Ampelmann previously used hydraulic transfer systems, employing a big power pack to operate cylinders and hydraulic hoisting winches. In this era of sustainability and energy conservation, Ampelmann approached the engineers at DROMEC Winches to jointly devise a more sustainable solution. This led to the electrification of 3 winch systems, resulting in a net consumption of 10% related to the previous big power pack, a significant reduction compared for the 31-meter-long gangway.

Kees-Jaap van Nes, Senior Project Manager at Ampelmann, says,
“I am very satisfied with our collaboration with Dromec. It’s a great product developed through excellent teamwork.”

Crane Hoisting Winch

The offshore vessel navigates to the wind turbine for various maintenance and operations tasks. An electric hoisting winch installed at the tip of the gangway enables the gangway to function as a crane. With a high nominal load, tools are hoisted to the wind turbine. To reduce weight, this winch is predominantly constructed with lightweight components. This upgrade allows the crane to transfer more equipment with a peak speed.

Telescopic Winches

The gangway features a telescopic extension system with 2 winch systems, each capable of exerting a powerful force. This system is fully redundant for safety and operational reliability. Operating under constant tension, the entire system is heavily utilized, even in seas with a significant wave height of 3.5 meters. With a peak speed, the gangway can extend and retract using the winch system.

Height Adjust Winch

At the base of the offshore vessel, there is a large winch, which raises the entire gangway to the required height. Powered by dual motors, the gangway can be lifted 15 meters. The redundancy of dual motors ensures operational reliability. It is possible to position the gangway using a single motor at a lower speed if needed.

Geerart, an engineer at DROMEC, says,
“With Ampelmann, we truly reach an optimum solution. We understand the technical aspects together and are capable of collaboratively improving for the future. The transition from hydraulic to electric power has significantly reduced energy consumption. Our alignment in terms of system control is also remarkable. There is mutual appreciation, and based on this initial design of the upgraded winch systems, more innovations will follow.”

Winches for Van de Gruiter

On behalf of Van de Gruiter we developed a unique set of winches. For the outfitting in the Netherlands a yacht needs to be transported behind a tugboat through a number of sluices. During locking, the tugboat and the yacht cannot fit into the lock simultaneously. For this purpose, DROMEC Winches developed a quadruple winch system on the hull of the yacht.

Quadruple winch system

Using 4 electric mooring winches with a pulling force of 5500 kg on deck 1, the hull is secured before entering the lock. The tugboat passes through the lock. Subsequently, the 70-meter cables with a diameter of 28mm are attached to the bollards in the lock. The 4 winches with controls pull the hull into the lock. After locking, the cables are disconnected and reattached to the tugboat. Similarly, the hull is then pulled back to the tugboat.

Free-wheeling clutch

The 4 winches are identical, they are mirrored at the bow and on either side of the aft deck. The cable is retracted at a speed of 10 meters per minute. The winches are equipped with a manually operated free-wheeling clutch, a crucial requirement for these winches. With a drum in free-wheel mode, the operators on shore can pull the cable to the bollard. And once the cable needs to be released, the drum goes into free-wheel mode. When the cables need to be retracted again, the drum is reconnected to the drive for rewinding.


DROMEC Winches has mounted a frequency-controlled control system on the winches. With a user-friendly handheld controller, the operator can incrementally increase and decrease the speed with push buttons.

Joost Ressing:
‘We have connected a control system to each winch, making it a complete set that is versatile. This way, multiple yachts can be moved over long distances. The collaboration with Van de Gruiter was pleasant, and communication was good on both sides. Despite the tight delivery time, everything worked out well!’

Ingenious winch system

DROMEC Winches has developed an ingenious winch system to safely tilt a high-tech and valuable object for special international transport.

Cees Drost from DROMEC states,

“Within Dromec, we have a dedicated production location where systems for the cleanroom industry are assembled. This space has its own setup in terms of tooling, reflecting the high-quality standards that our company can achieve.”

Specials equipment for DICK&DOOF Curacao

DICK&DOOF has an excellent reputation in all areas of mechanical construction within the energy sector and downstream activities in the oil and gas industry. D&D specializes in transportation, demolition, and construction, serving as an industrial contractor for Royal Dutch Shell in the Caribbean and Latin America. For a project in Suriname, DROMEC Winches developed two winch systems with controls.

Electric winch in frame

The electric winches with a pulling force of 2 tons are used to pull stove pipes at a construction site. The winch systems can also be deployed in storage tanks to move bottom plates. A special ECH-2000 frame with cutouts has been developed for these winches, allowing them to be moved on with a forklift.

Roelof van Urk, DROMEC:
‘We have these winches in stock as standard. We were able to deliver them with frames within 5 weeks. For DICK&DOOF, this quick delivery time was crucial for the Suriname project.’

Efficient winch system

With this plug & play principle, the winch systems can be efficiently used for various tasks. Even in D&D’s future projects, the winches can be deployed internationally for the realization of new constructions.

Manoel da Silva, D&D:
‘Our experience from the purchase process to the delivery from DROMEC has been perfect. Agreements were duly fulfilled!’

DROMEC Winches develops umbilical winch for Seatools

Seatools is a subsea technology company that provides high-end solutions for a wide range of underwater challenges. The majority of solutions they deliver are custom-made and cater to markets ranging from aquaculture to offshore oil and gas. DROMEC Winches has developed a special umbilical winch for Seatools.

Umbilical Winch

The depth of the sea is a determining factor for placing offshore wind turbines. Foundations are realized by driving so-called pile casings into the seabed, which generates significant vibrations that can disrupt marine life. These vibrations need to be minimized as much as possible. Using a specially developed bubble curtain, where air is blown into the water through holes, the vibrations are dampened. To supply air to the system, a 150-meter-long hose is extended from the sea vessel. DROMEC Winches has developed an umbilical winch for this application.

Constant Tension

As the bubble curtain descends to the seabed, the electric umbilical winch automatically pays out the hose using Constant Tension. This CT function monitors the preset maximum allowable tension on the hose, thereby preventing damage. With a pulling force of 1500 kg and a hose width of 90 mm, it is a relatively large system. In this project, DROMEC also provided special controls so that the client can remotely operate the machine. In case of unforeseen extreme weather conditions, an “hammerlug” coupling can be used to disconnect the air hose from the winch and float it overboard. Additionally, the winch is equipped with a spooling mechanism to ensure the hose is neatly wound on the drum. An additional spool guide prevents damage to the umbilical hose. The entire system is compactly built within a shipping container frame, making it easy to transport and relocate during offshore operations.

Paul, engineer, says,
“Seatools is a great company, and there is much appreciation for their quality and expertise. DROMEC Winches aligns well with Seatools in terms of mentality, engineering, controls, and assembly, making it a pleasant collaboration!”

DROMEC builds series of Pull-In Systems

Van Oord is a leader in offshore wind farm construction. The company is responsible for the cable pull-in operation for the Sofia Offshore Wind Farm project located on the Doggersbank in the North Sea. This operation involves providing the wind turbine with power cables to transport the generated energy. In 2019, DROMEC delivered a special series of 10 user-friendly pull-in systems for this application and is now supplying another series of 10 systems.

Stefan Graat, Project Engineer at Van Oord:
“Dromec provides Van Oord Offshore Wind with equipment, support, and services that make a significant contribution to successful cable projects!”

Pull-In System

The pull-in system, developed specifically by DROMEC, is used to draw the thick power cable from the ship into the wind turbine. It is a complex tool designed for this purpose. Specific variants have been designed for different continental areas. For instance, in the waters of the United Kingdom, additional safety standards are required, such as LOLER and PUWER.

Constant Tension

Before installing the wind turbine on the platform, the pull-in operation takes place. The cables are pulled from the ship through the seabed into the platform using the DROMEC pull-in system. This system features a constant tension function, ensuring that the cable is always kept at a preset tension, even when unexpected changes in cable force occur. This prevents cable overload. This special tool has a nominal pulling force of 10 tons, which is maintained through friction between the rope and a special capstan head. The combination of the number of wraps and a fairlead ensures the safety of the pulling force up to a holding force of 12 tons.

Pieter, engineer DROMEC:
“We designed this compact pull-in system specifically for operations of this kind, and since then, the demand from various customers has significantly increased. It’s a user-friendly tool that can be installed for any pull-in operation on a random platform. The combination of its low weight and high force, along with advanced control software, provides real time savings for the customer. The system can be used both in a standing and hanging configuration. Various improvements have been made for the new series, such as the nominal pulling force and the hard-anodized capstan head. This material is more resistant to corrosion. The frame is also more user-friendly with an integrated lifting eye and an additional guide bracket, allowing the cable to wind on and off at a 70-degree angle.”

Automatic Tensioning

The system operates with automatic tensioning. A fairlead that runs in sync with the capstan head through the control system ensures a consistent tension between the fairlead and the capstan, guaranteeing the pulling force by the capstan without the need for a person to hold the loose end continuously. The system is electrically powered, compact, and lightweight, weighing 550 kg. It weighs 475 kg without the detachable fairlead. Once the operation is complete, the system is moved to the next wind turbine platform.

DROMEC Winches develops ingenious winch system

Cordeel Netherlands is involved in a wide range of construction projects, from residential to commercial. They work in various sectors, focusing on sustainable building and customized solutions for new constructions. For the Clubhouse Boompjes project in Rotterdam, WVH Facade Technology approached DROMEC Winches to develop an ingenious winch system for the construction of the residential towers.

Winch System for Residential Towers

Cordeel Netherlands, in collaboration with WVH Facade Technology, is constructing two residential towers in Rotterdam, with heights of 100 and 70 meters. The bare concrete structures are being further developed using finished facade elements. These 1200 kg facade elements are lifted into place using a DROMEC winch system. What sets this system apart is the bottom-up assembly of the residential tower, with each floor being progressively expanded in 5 steps.

Electric Drive

WVH designed the residential towers with floor grooves to facilitate the lifting of facade elements. On each floor, two winch systems with a combined lifting capacity of 2 tons are installed in lifting frames. These lifting frames can extend up to 1.5 meters and are stabilized. On the ground floor, two tagline winches are in place to maintain Constant Tension on the element in the correct position. As the element reaches its destination, it is slid into place using the lifting frames. DROMEC Winches also integrated a third lifting frame into this design, providing the ability to lift ceiling elements. All winch systems are electrically driven, which is of significant environmental importance in cities like Rotterdam.

Constant Tension

In this ingenious winch system, the control system plays a pivotal role, as all components must work in harmony to ensure a safe working environment. The three lifting frames can be operated simultaneously with a single joystick, and they can also be controlled individually for fine-tuning the lifting operation. The Constant Tension tagline winches on the ground floor can be operated remotely through the control system.

Gijs, the engineer, states,
“The winch systems working together allow for very precise positioning of facade or ceiling elements through Constant Tension. This is especially significant in urban areas with high-rise buildings.”

Compact and Safe

The winch system is designed to be highly compact and can be placed in the construction elevator. Each lifting frame, weighing 1000 kg, is equipped with wheels for easy mobility. The winch system has a cable storage capacity of 110 meters and is secured with a Dyneema chain. In case of cable breakage, the Dyneema chain serves as a safety measure. With this winch system, DROMEC Winches has once again elevated the bar for their projects.

DROMEC Constant Tension machines

DROMEC Constant Tension machines are known for their multifunctional spooling capabilities. These machines find applications in various market sectors, ranging from spooling and unspooling electrical cables to winding heavy tow wires for offshore vessels. Over the years, DROMEC has developed a diverse range of winches in terms of power and size.

Electric Drive

What makes DROMEC special is the deliberate transition to exclusively using electrically powered systems a few years ago.

According to Cees Drost,
“This transition has brought DROMEC two significant advantages. Firstly, we have reduced environmental impact by eliminating diesel emissions. Secondly, our machines can be controlled with much greater precision, allowing even highly sensitive umbilical wires to be spooled without risk, thanks to integrated data logging. Furthermore, our system offers the capability to generate electricity during the project itself. These machines are often employed in opposite position to other winches or reels, where customers require specific tension requirements. During spooling, we can switch the motor to act as a braking dynamo. This not only results in emissions savings but also energy savings, especially in situations where work is predominantly carried out indoors. In the absence of a power source at a project site, there is always the option to activate a small and energy-efficient generator, a requirement in less than 5% of projects.”


DROMEC primarily sees these machines being used in markets such as rigging companies, where long lengths are converted into customer-specific lengths for both steel and fiber ropes. Another application involves replacing steel cables on cranes and pile drivers, where old wires are first spooled onto an empty reel before the new or clean cable is wound under tension on the machine. DROMEC spooling machines are also widely used for wire inspection. In this process, wires are degreased, inspected, re-greased, and immediately spooled under tension on the winch, all in a single back-and-forth motion.


Upon request, DROMEC Winches can offer more extensive customer-specific features, such as Active Heave, line measurement, high-speed capabilities, or specific pulling forces. DROMEC spooling machines vary in pulling force, with the smallest machine having a pulling force of 60 kg, and the largest machine exerting a pulling force of 42 tons (at the core). For newly developed spooling machines, two essential parameters are always considered: the maximum weight of the reel within the machine and the desired pulling force. At DROMEC we are always up for this challenge!

DROMEC Winches develops winch systems

Kooiman Marine Group is an independent group of multi-disciplinary shipbuilders in the maritime sector. On behalf of Kooiman Marine Group, DROMEC Winches has developed specialized winch systems for the dredgers Maas and Mursy operated by Van Oord.

Active heave

On both sides of the dredgers, there are 25-meter-long injection pipes used to dislodge the seabed with water jets, allowing it to be carried away by the water’s flow. The pipes are lowered into the water at an angle using the winch system. The winches are equipped with active heave, which ensures that the pipe remains at the same height above the seabed, compensating for wave motion. Both the Maas and the Mursy are equipped with two winches.

Absolute encoder

The electric hoist winches each have a 110 kWh electric motor. The working load for lowering the pipes is 30 tons, with a peak load of up to 40 tons. The holding force of the winch system is 45 tons. In the event of a cable breakage, the ship can pull the winch up to the waterline and proceed to repair. What makes this system unique is the interconnection of the winches through an absolute encoder that records the motor positions. This synchronization allows the pipes to be lifted in parallel. When combined with active heave, this means that the system is constantly in motion. The active heave capacity is 20 tons, with a wave height of 400 mm amplitude within 7 seconds.

Jan Willem, engineer: “The control of the winch system is truly exceptional for these Van Oord vessels. We have had a positive collaboration with Kooiman Marine Group, with clear agreements in place. They entrusted us with the development of this system, and as DROMEC Winches, we have delivered on our promises. It’s satisfying to know that we are now building a series of 4 winches for 2 new vessels once again.”

Efficient winch systems for Coreworks

Coreworks is a company specialized in building stages and scaffolding based on steel frames. These are temporary structures for various events. Using a pulling winch system, large tent fabrics or sails can be pulled over the frames. In the past, this was done with a lot of manual labor, but now with the help of an efficient winch system.


Winch system with foot pedal

The winch is attached to a construction vehicle, such as a forklift or telehandler, for Coreworks. One person can operate the winch using foot pedals, allowing their hands to be free to finely and evenly pull or release the rope. The system is very simple to use. The operator wraps the rope around the drum, and on the other end, it is attached to the sail. Through the friction between the rope and the drum and by accelerating with the foot pedal, the person can pull a load of up to 600 kg with just 20 kg of force.

The pulling force of the winch for Coreworks goes up to 1 ton. Since the system is mounted on a construction vehicle, it is highly flexible to use. Despite the immense pulling force, the system can be connected to a regular 230V plug or construction power outlet.


Multifunctional tool

DROMEC Winches has built a good relationship with Coreworks over the past years. With this versatile system, they work together with the customer so that they can reuse this system for every event. It truly is a multifunctional tool that saves a lot of manpower. By using this winch system, Coreworks can efficiently and safely assemble events with less effort and manpower.

DROMEC Winches Supplies Winch System for FLEET CLEANER Delft

FLEET CLEANER Delft specializes in cleaning seafaring vessels in ports such as Rotterdam, focusing on efficiency during the loading and unloading processes. DROMEC Winches has supplied a winch system for the work vessel Thunderbird 4 of FLEET CLEANER, enabling environmentally friendly cleaning of ship hulls.


Umbilical System

Onboard FLEET CLEANER’s work vessel, a crane with a remote-operated robot, known as the ROV (Remote Operated Vehicle), is positioned. This robot is controlled remotely and connected via an umbilical cable to the system provided by DROMEC. Within this umbilical bundle, hydraulic, electrical, and data cables are integrated, along with a wastewater hose, allowing for eco-friendly water discharge. The winch is suitable for ATEX environments, enabling FLEET CLEANER to clean oil and chemical tankers as well.


Mechanical Coupling

DROMEC Winches’ winch system can spool up to 180 meters of umbilical cable. The fully electrically powered system boasts a pulling capacity of 2.5 tons and a holding force of 4.5 tons. The cable can be reeled in at a speed of 30 meters per minute. DROMEC Winches has specially developed a mechanical coupling on the cable guide, which is detachable, allowing FLEET CLEANER to manually adjust the cable. This feature proves particularly useful for the umbilical cable, which may not always maintain a consistent shape.


ATEX Certification

Jan Willem, engineer, explains,
“While this winch system has the size of a container, it is very straightforward to operate with just two buttons on the control panel for speed and winding. All components are ATEX-certified, except for the control unit located below deck. An interesting development is that DROMEC Winches now also develops winches with full ATEX certification, including control units. DROMEC has already developed a wide range of umbilical winch systems, providing us with a diverse selection of models.”

DROMEC winches designs electric spud pole system

DAMEN Shipyards Gorinchem focuses on design and construction of ships and pontoons in various sectors. DROMEC has developed a special spud pole drive system for a large crane pontoon (L x W = 76 x 32 metres), so that the pontoon remains on location in various weather conditions.

Using four systems, each on every corner of the pontoon, the spuds are driven into the seabed with a force of 85-160 metric tons. This means that the crane pontoon is anchored to the bottom and can carry out lifting and maintenance work. The 2 spud poles with a length af 30 meters each, are interchangeable in the systems, so that the pontoon can be anchored in each desired position. The spud poles of approximately 85.000 kg each are lifted into the system using the onboard 625 mT crane.

Electric drive

For this project DROMEC used electric rack & pinion drives. The system is equipped with a floating mode that allows the pontoon to move along with the waves.

Jan-Willem (system engineer):
‘The system is special because of the high forces that occur. By driving the poles into the ground with 160 tons, the pontoon is stable in all weather conditions. Because the customer can exchange the spud poles, he can work very efficiently.’

Absolute encoder

The entire system is powered, controlled and monitored from a central control below deck. Each spud can be operated separately via a local control unit near each spudpole station on deck. The crane operator receives all crucial values and alarms in the cabin, so that the system can be used safely during “in” and “outfeed” of the poles. DROMEC has equipped the system with absolute encoders in the drive line. This makes it possible to measure and monitor the exact pole length and position. In addition, all important data such as forces, speeds, positions etc. are constantly monitored and logged. Reading and online support can be realized remotely from the Netherlands and that is unique!

DROMEC pull-in system

DEME Offshore is a world leader in the construction of offshore wind farms. The company is responsible for, among other things, the pull-in operation in which the wind turbine is provided with the power cable. DROMEC has developed a specially designed and user-friendly pull-in system for this purpose.

Pull-in system

With the help of the pull-in system, the cables for power and data are pulled from the ship into the wind turbine. It is a complex tool that DROMEC has developed specifically for this purpose. Specific versions have also been designed for various continental areas. For example, in the waters of the United Kingdom, additional safety standards such as Loler and Puwer are required.

Constant Tension

Before the wind turbine is installed on the platform, the pull-in operation takes place. The cables are pulled from the ship into the platform over the seabed. The system has a constant tension function, which keeps the cable under a preset tension at all times, even when unexpected in- or decrease of cable force occurs. This prevents overload in the cable. This special tool has a nominal pulling force of 10 tons. The force is generated by the friction between the rope and the special warping head of the capstan. By the number of turns in combination with the back tensioner, the pulling force is guaranteed up to a holding force of 12 tons.

Pieter, engineer: ‘We designed this compact pull-in system specifically for this kind of operations, and the demand from various customers has since increased enormously. It is a user-friendly tool that can be installed on any platform for any pull-in operation. The combination of low weight and high pulling force in the system, using sophisticated control software, makes it a real time-saver for the customer. The system can be used both standing and hanging.’

Automatic back tension

The system works automatically. The back tensioner, which via the control works together with the special treated warping head, ensures that there is always sufficient-pretension between the back tensioner and the capstan. In this way the pulling force is guaranteed without need of a person holding the slack part. The system is electrically driven and is very compact, with a low weight of 475 kg. Once the operation is complete, the system is moved to the next wind turbine platform.

A committed family business that can realize a system from application to end product in a short period of time. In this context, DROMEC winches works together with highquality partners.

In the field of hydraulic, compact winches, Dinamic Oil is a reliable supplier.  DROMEC winches has a large stock, so that we can help the customer quickly and accurately in case of malfunction and damage. This small functional ‘liftingmate’ is also often used in newbuild projects.


The Dinamic Oil winch is used in various sectors as Inland shipping as a car crane winch, but also on trucks and compact cranes. The jib equipped with a winch is widely used on telehandlers, maritime- and offshore cranes. But also for agricultural mechanization, forestry and tree nurseries, the winch is a popular. At DROMEC winches, the service technicians also think along with you about the necessary accessories such as safety hooks, lifting blocks or cable that has been spooled under the right pres-tension.

Constant Tension; that’s the power of this windingmachine.

Constant Tension; that’s the power of this windingmachine. This system was recently commissioning at EFG Equipment. DROMEC winches builds this machine in series for on- and offshore.

With this system, a cable is rinse up and down under continuously adjustable load. In any sector where cables, ropes or umbilicals are winded with great precision, these machines are an efficient solution. Due to the precise and easy operation, the customer saves a lot of time and damage.

Bas Broekman of EFG Equipment: ‘We should have done this ten years earlier, which saved us a lot of time. We now change a wire from a drilling rig in 20 minutes instead of a few hours.’

Power and control

DROMEC winches builds the Constant Tension windingmachine from 1.5 to 250 tons. The pulling force increases from 500 kilos to 44 tons. This makes the system suitable for many segments.

Rigging, cranes, drilling and piling racks, winches and umbilicals are examples of markets and products that benefit from this machine. For accuracy, DROMEC winches builds the windingmachines with electric drive and control. In the context of sustainability, this is an advantage. For a specific application related to the machine, DROMEC winches engineers like to think along with the customer.


Unique to this machine is the control. DROMEC’s own developed software platform, customer-specific wishes for the winding machine are realized. DROMEC winches engineers can watch worldwide in the event of a malfunction. With this platform, the system is able to recover energy. The application of active heave linked to the Constant Tension machine is also a development in which DROMEC winches excels!

Custom EWA-650-KB anchorwinch

This week we again supplied an EWA-650-KBV wire anchorwinch. Due to the onboard situation, the requirement was to position the winch directly near the living area, to realise extra free deck space.

Because of this a modification to the bandbrake handle was needed. Now the handle points horizontally forward instead of the standard vertical position.
Also a 35 x 7 non rotating cable is spooled on the drum with right pre-tension. This cable is equipped with an open spelter socket to make anchor assembly quite easy.

Are you looking for a standard anchor winch or are you looking for a special execution? Dromec provides a solution!

Compact, safe and powerful winches

In recent years, we supplied several winches to our customer Waternet Amsterdam. De winches on the photo’s where supplied in 2019 and are used as couple & mooring winches.

In that time, the customer required powerfull and safe winches with minimal impact on shipdesign and free deckspace.

Because outgoing cables run below deck and are completely covered, a safe working environment is created.

Recently we replaced new stainless steel drum covers.

Dromec designed and build special cable spooling machine for DEME

In the field of spooling machines, Dromec already designed and built many different versions however, this EPW-750-400-KTPF was special again.

This so called “Electric Constant Tension System” can work in a forcerange between 7 and 17 mT and can handle a reelweight of 40 mT !

Via Dromec’s wired full color  HMI,  the operator has realtime information about adjusted and realtime speed and torque values on each specific cable layer.

This spooling machine will be applied on board of Deme’s Spartacus for rewinding the winches with new steel cables under the right pre-tension. Because of the special design, the cable can leave the machine at several locations so all ships winches can be reached while the machine itself can remain in 1 fixed location.

UFO restaurant Rotterdam

During a weekend trip in Rotterdam,  I came across an old acquaintance of Dromec in the magazine “Inside Rotterdam” namely the UFO restaurant.

In this unique restaurant you can dine at a height of 42 meters and while the floor rotates slowly, you have a 360 degree view of the Rotterdam skyline. Dromec designed and built the top section of this tower.

The top section houses 4 Dromec hydraulic HPH-20000 winches, controls and the hydraulic power packs to raise and lower the restaurant in a safe and comfortable way  .

This project shows Dromec’s strength, namely providing turnkey customer specific solutions.

Dromec supplied 2 pcs. Rotating Bollards to GMS REIMA Binnenschifffahrt

After a lot of positive reactions from inland shipping colleagues about Dromec’s Rotating Bollard, Mr. Reinhold Martin from GMS REIMA Binnenschifffahrt got also interested. In the meantime 2 of these special capstans are on it’s way to his ship.

Mr. Martin made a good choice we think! Dromec’s rotating bollard combines the characteristics of a  capstan with a classic static bollard. The special compact  design results in more free deck space and a static  holding force of 15mT.

Besides that, this EPK-5000 saves also time because  in most situations mooring can be done by 1 (one) person.

Kitepower & Dromec: Building the New Generation of Wind Energy Systems

Kiterpower published a great testimonial about our tailor-made winches, winch systems, controls and power transmission. You can read the full article here: https://thekitepower.com/kitepower-and-dromec-building-the-new-generation-of-wind-energy-systems/

Dromec specializes in tailor-made winches, winch systems, renewables,  controls, reel machines and power transmission. Dromec’s approach assures the highest reliability in power transmission applications and boasts dynamic and innovative manufacturing techniques when it comes to winch systems. Such features had made Dromec a key development partner of Kitepower since day one, when back in 2015, at the time of REACH, the Dutch company has joined the mission to develop Kitepower’s first commercial Airborne Wind Energy System (AWES).

The role of Dromec is to manufacture the ground station (GS) of the Kitepower AWES, an exclusive development path that so far has brought to life two versions of Kitepower’s combined smart generator and winch system. Within a Kitepower system, the ground station is the component that converts the mechanical energy of the kite into electrical power and is also used to reel the kite in and out by using the generator as a motor.

Kitepower is proud to be cooperating with Dromec in the construction of an energy system capable to play a significant role in the EU’s energy mix and majorly contribute to the global energy transition to renewables.
