Abstract (en)
[origin: EP1138833A1] The quick coupling device comprises a bolt element (6) acting as a locking element that is pushed constantly into the engaged condition by springs (7) and in the opposite direction by the temporary interventions of a hydraulic jack (4). The bolt element (6) is provided with two holes (6A,6B) adapted to receive, one the end of an emergency lever (3) for emergency manual disengagement and the other one a safety pin (5) which is retained in the respective hole (6B) by the thrust of a spring. The safety pin (5) can be retracted both hydraulically and manually, at a protruding hook end (5A) thereof with which a lever (11) can be engaged when necessary. <IMAGE>
