<p>PURPOSE:To obtain smooth positioning and to prevent a transporting truck from turning over by installing a driving elevator for a positioning member to the lower frame of a table which makes floating motion horizontally in relation to the truck main body and by shifting the weight of the truck main body to said lower frame when the elevator is elongated. CONSTITUTION:A table lower frame 2, which supports the cargo table 3 in such a manner that the table 3 can freely extend and retreat in the lateral direction, is constructed so that it can make floating motion in the horizontal direction in relation to the truck main body 1. The table lower frame 2 is provided with a driving elevator 5 for a member 4 for positioning in the horizontal direction in relation to floor 6. In addition, an impressing mechanism 9 consisting of a supporting member 10 and a retaining member 11 is provided between the truck main body 1 and the table lower frame 2. The impressing mechanism 9 functions in shifting the weight of the platform main body 1 to the table lower frame 2 by abutting the supporting member 10 against the retaining member 11 and lifting the truck main body 1 after extending the driving elevator to fit the said member 4 onto a positioning member 7 on the floor 6.</p> |
