Modular designs coupled with our global production and distribution centres located close to the world's main shipbuilding centres, means short lead times.
Select from all-electric, high-pressure or low-pressure hydraulic drive options to match your requirements. Each winch is built of modules that include the drum, shafting with accessories, brake, bearing bracket, warping end, gear and drive.
Towing winches and systems for harbour tugs
Towing and escort winches can be supplied with a number of different drive options including low and high pressure hydraulic and all-electric. They are compact, rugged and reliable.
Frequency-controlled winches using technology from our anchoring and mooring packages supplied for cruise ships, are a worthwhile option for some tug applications and have a number of advantages: easier installation; reduced start-up costs, space savings, greater freedom of deck layout and immediate availability for use.

Anchor and mooring winches
The modular concept
Select from all-electric, high-pressure or low-pressure hydraulic drive options to match your requirements. Each winch is built of modules that include the drum, shafting with accessories, brake, bearing bracket, warping end, gear and drive.
Options include remote control for brakes and clutches and an auto-tensioning system that automatically keeps the tension in the mooring line within pre-set limits automatically. Windlasses are made up of a cable lifter unit, a pinion shaft and the clutch and brake module - the drum size and the main shaft line are open design parameters and can be specified. Mooring winches can be supplied with pulling capacities from 5 to 40 tonnes and anchor windlasses for up to 137mm chain.
Low-pressure hydraulic systems are often the preferred choice for LNG carriers and large VLCC's where safety is a vital consideration. Systems are capable of delivering high-speed dynamic lowering of the anchor, up to 40m/min.
Low-pressure systems have now been installed on more than 100 LNG vessels, which is approximately 40 per cent of the total market share worldwide.
High-pressure hydraulic systems are a popular choice for oil product and chemical tankers. They can be directly integrated with the vessel’s central hydraulic system that is used to drive the cargo pumps, so there is no need for a dedicated power pack.
Frequency controlled winches are now the natural choice for cruise ships where speed, step-less control and quiet operation are important.

Low-pressure hydraulic
The low-pressure hydraulic is originally designed for heavy winch operations in marine environments. Through more than 70 years of experience the feedback from our end users have been that low-pressure hydraulic winches are exposed to minimal risk for off hire, caused by total breakdown.
The system has the market’s highest focus on safety and lifecycle cost. It is robust, reliable and easy to install. The winch motor and power pack operates at very low noise as part of a constant flow system at max 64bar, with variable pressure depending on the flow requirements of the winch.
The vane type winch motor provides step-less speed control and automatic speed selection with full starting torque. Its three-chamber design allows an increase line speeds in light line situations by up to three times with full hydraulic control. All parts are based on in-house technology.
We focus intensively on reserach and development and take advantage of our tremendous skills acquired through operating in all maritime markets.
This has resulted in a unique business process that gives you the optimum solution for your vessel, with the benefit of minimum lead time, guaranteed on-time delivery, close follow-up and life-long product support for the module-based winches.
Regional expertise, combined with a global and local presence and our vast experience ensure the best possible client-focused solutions - whether it be electric or hydraulic systems.
