Abstract

PURPOSE: To perform discharge of the load of a dump truck quickly by guiding forcedly a link mechanism, which works in linkage with tilting of the rear body, so that the rear dump door is opened fully in the initial period of tilting.
CONSTITUTION: When the rear gate 9 of a dump truck is closed, a roller 18 in a link mechanism 10 is pushed against a guide member 17 by an elastic member 23 and, thereby, hindered from movement so as to hold the rear dump door 9 shut perfectly. When the rear body 2 is tilted, the roller 18 rolls on the guide part 21 of the guide member 17 and links 13, 16 turn around a shaft 11 to allow the rear gate 9 to open fully with the aid of a rod 15. The roller 18 is, at this time, located at the start point of a retainer guide part 22 and, when tilting has gone further to the maximum tilt angle β, rolls on the arc-shaped retainer guide 22 to restrict turn of the links 13, 16. Thus, the rear dump door 9 is now held fully open and discharge of the load can be performed quickly.
