ABSTRACT:
Stabilizing apparatus for a dump vehicle including a dump box pivotally movable about a frame between lowered and elevated conditions utilizes two leg members each having two end sections which are movable relative to one another in a telescoping fashion and hydraulic cylinders for telescopically moving the end sections of each leg members relative to one another. One end of each leg member is connectable to the dump box adjacent a corresponding side thereof for pivotal movement relative thereto between a first condition at which the leg member is positioned generally alongside the box for storage and a second condition at which the leg member extends angularly downwardly from the box for engagement of the other end section of the leg member with the ground. The hydraulic cylinders telescopically move the end sections of the leg member as the dump box is moved relative to the frame between the lowered and elevated conditions so that the other end section of the leg member is maintained in engagement with the ground as the dump box is moved relative to the frame so that the leg members brace the dump vehicle against forces which tend to tip the dump vehicle upon one of its sides.
