APPLICATION WINCHES

Hydraulic winches are used in various fields all over the world. One of the most demand-
ing applications is surely on board ships, where salt water and high temperature differ-
ences affect the construction. Outstanding reliability and availability are certainly among
the most important features of all systems used on the high seas.

FUNCTION
Winch systems on ships are used for lifting and lowering an-
chor chains, for installing underwater cables or for setting

down and hauling nets and fish traps for fishing. In many
applications, precise control of the rope tension in every op-
erating phase is of the highest importance. Whether it is to
avoid damage or to ensure the safety of the workers on the
ship. The winch control is usually integrated into an overall
system and interacts with a crane boom control or a linear
cable engine, for example. Especially on large ships in rough
seas, extreme forces act on the individual systems. These
must be able to absorb the forces and have a high reliability
so that the loads can be quickly hauled in the event of an
impending storm.

COMPONENTS
Valves with increased corrosion protection and stainless
external parts are mostly used for controlling the winches.
When proportional valves are used, the associated control
devices are pre-parameterised on the basis of the system
reference values, so that the customer only has to readjust
them slightly in the overall system using the intuitive PASO
software.

SPECIALTIES
• Explosion protected valves
• Corrosion protected valves
• Valves with integrated electronics and controllable via CAN bus
• Customer-specific adaptations possible
