問題があつた。 Conventionally, in power-driven vehicles, the engine section and the transmission section are placed on the same side of the drive pulley and main clutch pulley, on which the transmission belt is stretched to transmit power from the engine section to the transmission case. On the other hand, the hydraulic pump and hydraulic switching valve for the hydraulic cylinder of the platform dump attached to the main drive pulley are arranged on the opposite side of the transmission belt from the engine section and transmission case. For this reason, the hydraulic hose installed between the hydraulic pump and the hydraulic switching valve has an integral structure with the hydraulic pump, so it is stretched in the opposite direction from the inside of the transmission belt to the outside of the transmission belt. It was connected to the hydraulic switching valve. For this reason, the tensioning of the hydraulic hose becomes complicated, and there is a risk that the hydraulic hose may come into contact with the transmission belt.
