Control system for controlling the speed of displacement of a hanging load and lifting apparatus comprising such a system.

摘要

The invention relates to a system for monitoring and controlling the displacement of a hanging load. The system according to a preferred embodiment of the invention comprises a speed control (t i t), a ramp generator (gr has m p e) and of the circuits (100) for controlling the speed (v (p)) of the hanging load. & br / according to the invention, there is a chain of the retroreflector - action (131) whose output is connected to an input of a comparator (140) which receives on its other input of a control signal of the reference speed (r (p)). br / the output signal is transmitted to the circuits (100) of the speed control. The retroviral - action (131) is determined in order to stabilize the output speed. & br / application to the pipe assisted lifting apparatus, in particular port.
