Document Type and Number:
Japanese Patent JP2020055441
Kind Code:
A
Abstract:
To effectively prevent occurrence of an unexpected situation even if a plurality of operation switches for selectively performing a dump raising/lowering process and load-platform loading/unloading process are erroneously operated at the same time in a transport vehicle designed such that at least the front part of the load platform is engaged with the top of a swing frame, pivotally supported on the rear part of a vehicle body, so as to be movable forward and backward, the swing frame is allowed to erect and swing together with the load platform by means of a raising/lowering cylinder, and the load platform can be driven between the furthest backward inclining position where the rear end of the load platform is in contact with the ground and the furthest forward loading position on the top of the swing frame in a lowered position.SOLUTION: A hydraulic control device C that operates and controls at least either raising cylinders Cc or slide cylinders Cs on the basis of an on-operation of each of operation switches SW1 to SW4 stops at least all of the raising cylinders Cc and the slide cylinders Cs when another one of the operation switches SW1 to SW4 is on-operated during on-operation of one of the operation switches SW1 to SW4.SELECTED DRAWING: Figure 12
