Abstract (en)
[origin: EP1473415A1] The device has a hydraulic locking jack (10) with shank tip having a bolt (26) to cooperate with a tool. A distributor has a drawer (19) to link an accumulator (15) to chambers, in a locked position. A detector detects a coupled position of a coupler on the tool. An electromagnetic valve (22) feeds the chambers that are placed before the jack and a security jack (12), and implements a hydraulic cover (24) behind the jack (10).
