PURPOSE:To relieve and suppress instability of a load-carrying platform during inclination of the load-carrying platform, by forming an interlocking mechanism which causes movement of wheels to depend upon the damping motion of the load-carrying platform. CONSTITUTION:With a cylinder 12 for dumping, hydraulically operated, a load- carrying platform 4 is inclined centering around a fulcrum axle 10 acting as a fulcrum, resulting in movement of the center of gravity of the load-carrying platform 4 to the rear, and in which case, an interlocking link 14 of an interlocking mechanism 5 draws backward a bogie frame 7 and wheels 3 are moved backward. This enables redressing of instability of the load-carrying platform 4 caused by movement of the center of gravity with which inclining dumping operation of the load-carrying platform 4 is attended. Further, when the load- carrying platform 4 is operated to a horizontal position, the bogie frame 7 is moved forward to its original position through the working of the interlocking link 14. |
