Ship technology on deck
Whether you need cranes or hoists for safe and precise ship loading and unloading, RoRo equipment, loading hatches or winches – HYDAC is your partner for ship superstructures. With our wide range of components and systems, you get everything from a single source. We actively support you with our on-site service.
On deck applications for the shipping industry with worldwide approvals
Cranes & hoists
Strong winds, high humidity, rough tides – cranes and hoists on ships are almost defenceless against the weather. Nevertheless, they have to work with high precision when loading and unloading, whether it's at a harbour or on the open sea. Complex crane applications need finely tuned systems: from drive units and motor cooling for electric hoists to hydraulic accumulators for wave compensation systems. Perfection is required here. And HYDAC delivers it.
Applications for cranes & hoists
HYDAC pumps
Whether it's variable displacement or fixed displacement pumps – our pumps operate quietly and are ideal for use on the high seas due to their compact design. Our pumps are also suitable for potentially explosive atmospheres thanks to ATEX certification.
HYDAC sectional control block LX-6
Rely on our load-sensing sectional control blocks for sensitive response behaviour. They have a compact and energy-efficient design for hoist and crane applications on deck.
HYDAC hydraulic accumulators
Cranes and hoists of all kinds are exposed to strong forces. HYDAC hydraulic accumulators are responsible for energy storage in wave compensation systems and safety systems. Find out more about our innovative accumulator technology.
HYDAC hydraulic cylinders
Reliable solutions for precision tasks. Our hydraulic cylinders with special corrosion protection move the booms in your crane applications. Explore our wide range of cylinders. We also have specialised solutions for special ships, such as suction dredgers and floating dredgers, in our range.
Loading hatches & roll-on roll-off equipment
Opening and closing: hatch covers, bow doors and stern doors are frequently in motion. They need to work perfectly and reliably to protect freight and transport passengers. Make life easy for yourself – in addition to hydraulic cylinders and drive units, our complete hydraulic package includes the right valve control technology and sensor technology. Contact our experts for a custom hydraulic solution.
Applications for loading hatches & roll-on roll-off equipment
HYDAC hydraulic cylinders
For safe navigation and travelling in shallow waters – our hydraulic cylinders reliably help you lift your drive propellers. Discover our wide product range.
HYDAC sensors
Ensure increased functional safety on deck with our sensors for pressure, angle, position and linear position. These allow your applications for loading hatches and roll-on roll-off equipment to work reliably.
HYDAC electric cylinders
With a speed of up to 1 m/s, our HEZ series electric cylinders help to stabilise boats on waves. You can rely on the dependable cylinders from HYDAC for flap adjustment.
Winches
Nautical winches work at their maximum performance level to keep your ship in place. When ships are anchored or hauled to another location, the robust winches have to withstand the forces of the water.
Did you know? The advantages of the hydraulics can be fully utilised, especially when it comes to hydraulic winches. This is because special hydraulic accumulators can store the energy released during active wave compensation and release it at a later time. Sophisticated systems from HYDAC make this possible.
Applications for winches
HYDAC drive units
Our drive units are the ideal choice for on-off or proportional brake control. Our compact units are suitable for use in electric winches.
HYDAC pressure sensors
Maximum safety for your winches on deck: for accumulator pressure detection, you need reliable pressure sensors and switches. For this reason, our products have type approval from all renowned classification societies.
HYDAC directional control valves
Our directional valves control actuators in hydraulic circuits and control the oil flow. We offer a wide selection of poppet and spool versions – our range also includes Ex versions.
HYDAC gearbox cooling
Reliable cooling is required for ship winches to function perfectly. Choose between air cooling, liquid cooling and plate heat exchangers. HYDAC has the right products on board – with corrosion protection included.
