Abstract

PURPOSE: To simplify the mechanism and to improve safety by securely engaging hinge shafts by a fluid actuators and locking them.
CONSTITUTION: Hydraulic cylinders 24R and 24L are expanded and hinge shafts 11R and 11L are held by rear right and left hooks 19R and 19L and engaging pieces 17R and 17L, and locked. Hydraulic cylinders 23R and 23L are contracted and front right and left hookds 18R and 18L are disengaged. When an oil pressure cylinder between a frame 2 and a tipper body 3 is expanded under this condiction, the tipper body 3 is inclined rearward with a supporting rod 9 as a supporting point. In the case the tipper body 3 is inclined to the right, the hydraulic cylinder 23R is expanded by a change-over valve, while the hydraulic cylinder 24L is contracted. Then, a hinge shaft 7R is held by the hook 18R and an engaging piece 16R, and locked, and the hook 19L is disengaged. Since other hooks 18L and 19R are under the same condiction at the time of rearward inclination described above, the tipper body 3 is inclined to the right with the hinge shafts 7R and 11L as supporting points when the hydraulic cylinder is expanded. In the case of left inclination, the similar procedure is applied.
