Abstract:
1. Coupling device for a handling trolley, comprising a drawbar ( 22 ) mounted at the front of the trolley and designed to co-operate with a hook ( 24 ) mounted at the rear of a towing unit, such that two such equipped trolleys may be used together, wherein the drawbar ( 22 ) of one coupling device has a longitudinal slot ( 36 ) in which the hook ( 24 ) of another coupling device is able to slide so that the said hook can slide in the said longitudinal slot such that the two trolleys may be connected together by the drawbar of one trolley's coupling device and the hook of a second trolley's coupling device, wherein the drawbar ( 22 ) is connected to the front of the trolley by articulation means ( 30 , 32 ) defining an articulation axis (XX) in such a way as to pivot between a coupling position, in which the drawbar extends substantially horizontally in order to co-operate with the hook, and a lifted position, in which the drawbar is in a raised position and is disengaged from the hook.
