Crane lift support winches

The system consists of four electrical driven, frequency controlled winches and is designed to secure cargo during crane operations. Each winch is supported by dedicated frequency inverters, equipped with constant tension (CT) functionality, load cells (2 load cells on each winch) and overload protection by mechanical torque limiter (spring tensioned friction lamella type). On request, the system can also be delivered with hydraulic drive.

The winch system is controlled by two radio remote control units (each radio remote control unit controls two winches). To ensure redundancy each winch is also delivered with a cable based local control panel.
