ンプ荷台の取付構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a loading platform supporting member that is rotatable around a first axis on a vehicle body, and when the loading platform is in a seated state, a first hook is provided on the right side of the loading platform supporting member and a second hook is provided on the left side of the loading platform supporting member. Two hooks are provided, each of which can be released from the connection and urged toward the connection side, and a third hook is provided on the right side of the vehicle body.
and a fourth hook is provided on the left side in a state in which the hooks can be freely connected and biased toward the connection release side, and the first hook
And with the third hook connected, the loading platform is moved to the second
The loading platform is configured to be swingable around a third axis with the second and fourth hooks connected, and the first and second hooks are connected to each other, and the loading platform is configured to swing around a third axis. The present invention relates to a mounting structure for a three-way dump platform, which is provided to allow the dump truck to swing freely around a first axis and either of the second and third axes facing in the longitudinal direction of the vehicle body on both left and right ends of the vehicle body.

虞れがあつた。 The above-mentioned device allows dumping around the first axis to be performed by rotating the platform support member, thereby controlling the hook, the pivot shaft for engaging and disengaging the hook, and the receiving member for the pivot shaft. The structure is simple, as only four pieces need to be provided, but if the spacing between the receiving members and the hooks is too close, mud may accumulate there, causing the hooks to malfunction. It is necessary to provide the receiving member and the hook relatively far apart from each other, and as a result, when dumping around the first axis, for example, when the cargo platform is raised, the dumper swings ahead of the supporting member, and the pivot There was a risk that the shaft would be tilted with respect to the receiving member and would unexpectedly come off from between the receiving member and the first and second hooks, causing the position of the loading platform to shift.
