PURPOSE:To prevent variation of the load-carrying surface on transferring of a load onto a truck by abutting an abutting member on the ground side against the bottom surface of an auxiliary bumper on the truck side and locking the same. CONSTITUTION:When a truck 6 is moved backwardly, a roller 7 on the ground side goes ahead along a tilting surface 9b of an auxiliary bumper 9 and then the bottom surface 9a and is stopped, when the auxiliary bumper 9 comes in abutment against a positioning stopper 22. Then, a directional control valve of a fluid cylinder 14 is switched by the display of a proximity sensor 14 to lock a piston rod 15 of the cylinder 14. When a load on a traverser is transferred onto the truck 6, the load applied to a load-carrying platform is increased, but as the bottom surface 9a of the auxiliary bumper on the undersurface of the load carrying platform is kept in abutment against the roller 7 of a lever 10 locked by the cylinder 14, the load-carrying platform 6a will not be depressed. |
