ABSTRACT:
A lift truck having a hydraulic power piping unit for interconnecting between a control valve unit and a hydraulic actuator, mounted and encased in a full free lift upright assembly arranged in front of the truck body. The piping unit has a first pulley unit held by a middle tie beam of the vertically liftable inner masts, for guiding one assembly of flexible hydraulic hoses hanging down in a loose U-shape and connected to the control valve unit. The piping unit also has a second pulley unit held coaxially with a chain wheel on a top of a piston rod of a free lift cylinder mounted on the middle tie beam of the inner masts, for supporting the other assembly of flexible hydraulic hoses connected to the hydraulic actuator. The one and the other assemblies of flexible hydraulic hoses are fluidly connected to one another by a hydraulic joint unit held by the middle tie beam.
