PURPOSE:To obtain a truck with a slidable carrier by providing a longitudinal sill under a carrier so that it is moved backward by an oil hydraulic cylinder on a rear frame pivoted with a front frame behind a rear shaft and also it is lifted by an arm rotated with the fulcrum shaft of the front frame as a center during the backward movement. CONSTITUTION:When a control lever 32 is operated and an oil hydraulic cylinder 28 is extended for loading a cargo on a carrier 14, a longitudinal sill 12 starts to move backward horizontally and is floated on a rail 7, and the front is supported by one roller 20 each at the left and right and the rear is supported by two rollers each at the left and right to be moved backward horizontally by a fixed amount. When a stopper 21 hits a roller 20, an arm 18 is rotated in the A direction and is erected, and when the arm 18 hits a rear stopper 23, the oil pressure feed to the cylinder 28 is stopped. Next, a rear drop door 24 is opened in the B direction to get in contact with the ground 26 for loading. On completion of the loading, the rear drop door 24 is erected and the cylinder 28 is contracted so as to move the carrier forward, then the arm 18 is rotated in the counter-A direction to hit a stopper 22 through a process opposite to that before, then the longitudinal sill 11 is moved forward in close contact with the rail 7 to be locked. |
