This option enables hoist speed to be automatically adapted to the hook suspended load.
This recent feature allows lift speed and motor torque to be dissociated: speed - for the reduction of cycle time to enhance hoist station productivity when running empty, and motor torque - for lifting when loaded to ensure precision travel with a maximum power margin.
Principle of operation
For the majority of uses with type A (ASR) motors (up to 35% of the nominal load), you can use the hoist with its nominal speed, or even beyond. This option makes it possible to automatically adapt the lifting speed according to the load on the hook.
