Device for handling load, has digital data processing unit i.e. microprocessor, generating control setpoint of drive unit based on distance measured by contactless sensor i.e. intention sensor

摘要

The device has a drive unit (2) constituted of a winch motor to displacably drive a load towards top and/or bottom. A control handle (4) controls the drive unit. Movable parts (4A, 4B) form a gripping part by an operator. A contactless sensor (5) i.e. intention sensor, provides data representing the distance (D4) between the parts of the handle. A digital data processing unit i.e. microprocessor, generates a control setpoint of the drive unit based on the distance measured by the sensor.
