<p>The device has a measurement unit (15) i.e. accelerometer, measuring the position and/or movement carried by a flexible link e.g. cable or and/or an element such as control handle (4) and/or a load gripper such as hook. The measurement unit transmits signal representing the position to a digital data processing unit (7) i.e. microprocessor. The data processing unit modifies the control setpoint of a link drive unit (2) in a preset condition of the position to reduce or stop the displacement speed and/or acceleration of the link, in raised and/or lowered position.</p> |
