ABSTRACT:
Method and equipment for the transfer of a cargo space (13) onto a vehicle and off the vehicle. The loading device comprises an L-shaped piece (6), the upper end of the vertical arm (10) of said piece (6) being provided with a grasping hook (11), and the rear end of the horizontal arm (7) or of its extension (4) being provided with a transverse pivot shaft (3), around which the L-shaped piece is pivoted by means of an actuator (8). The grasping hook (11) pivots around a transverse shaft (17) relative the vertical arm (10) of the L-shaped piece (6) during the movement of transfer of the cargo space (13). The vertical arm (10) or an extension (16) of the vertical arm of the L-shaped piece (6) is provided with a projection (24), in relation to which the grasping hook (11) moves when it pivots relative the vertical arm (10) of the L-shaped piece (6). In a certain position of the grasping hook (11), the projection (24) on the vertical arm is positioned at least partly in front of the open gap of the grasping hook (11), and when the grasping hook (11) has been pivoted away from this position, the projection allows the open gap of the hook to remain at least substantially open.
