Load compensator for lifting equipment, especially for loading nuclear power station reactor, includes actuator fixed to load bearing cable, brushless electric motor and overload or underload detector

摘要

A load compensator, especially for lifting equipment, to be activated when an overload or underload is detected, comprises an actuator fixed to the one of the ends of cable(s) (6) carrying the load (11), which causes positive or negative displacement of the cable(s) over a short distance relative to the overall length. The device is driven by a brushless electric motor (21) associated with a variator, itself connected to the overload or underload detector. An independent claim is included for a loading device nuclear power station reactor, comprising a carriage to be displaced along a rail track above the core of a nuclear reactor, having a lifting device consisting of a motorized (5) winch (4) for winding lifting cable(s) (6), the other end of which is fixed to a load compensator as above.
