Abstract

PURPOSE: To simplify a construction and eliminate the possibility of wrong operation, by separating hinges from each other for backward swing-down and sideward swing-down and separating hinge sections from lockup sections.
CONSTITUTION: For backward dumping, cylinders 14L, 14R are retracted for unlocking and a hydraulic cylinder 14C is expanded to lock up a shaft 8C on a carrying portion 11C by a hook 13C. When a hydraulic cylinder for swinging the bed of a dump truck up and down is expanded, shafts 8L, 8C, 8R are guided and supported on carrying portions 11L, 11C, 11R to swing the bed backward. For leftward dumping, the cylinder 14L is expanded to lock up a shaft 6L' on a carrying portion 10L' by a hook 13L and the cylinders 14R, 14C are retracted for unlocking. When the cylinder for swinging the bed up and down is expanded, the bed is swung down leftward as shafts 6L, 6L', 6L" act as pivots. Rightward dumping can be effected in the same way.
