Winches

Compared to hydraulic systems, electrical motors controlled by a VLT® or VACON® drive provide substantial energy savings, low noise operation and no risk of hydraulic oil leaks. Drives enable excellent speed and tension control and load sharing with several motors driving the same winch.

Advanced mechanical brake control eases stress on both gear and brake, while automatic DC hold preheating keeps the motor dry in standby mode. Robust open-loop control eliminates the need for fragile encoders in open deck environments. To enhance reliability, use highly dynamic active heave compensation functionality, which actively lifts the cargo.

Danfoss Drives’ solutions for the marine and offshore industry have the highest number of class type approvals from nine authorities: DNV-GL, ABS, Bureau Veritas, Korean Register, CCS, RINA, Lloyds Register, RMRS and Class NK.

This gives you the best possible choice when selecting drives for your marine application.  

Cranes

Variable speed drive control of cranes provides higher availability and productivity, compared to traditional hydraulic cranes. By using a drive, owners avoid overheating in the hydraulic oil system and typically benefit from a 15% shorter cycle time, due to faster movements.

The result is an environmentally friendly and efficient system characterized by:

  • Elimination of hydraulic fluid leakages
  • Only marginal losses in standby mode
  • High efficiency during normal operation
