Coupler hook for a lifting device for a tractor

Abstract

The invention relates to a coupling claw (10) intended for a tractor lifting device, comprising a coupling jaw (27), a housing (25) and a latch (2), which coupling claw (10) is adapted to attach the coupling ball (11) of a working machine or similar device to its coupling jaw (27) and to lock it with a latch (2) extending from the housing (25) to the coupling jaw (27). The coupling claw (10) comprises an actuator (40) adapted to press the coupling ball (11) against the contact surface (50) of the coupling jaw (27), eliminating the clearance (44) between the coupling ball (11) and the coupling claw (10).
