Abstract: This invention relates to a device for supporting a lift roll for a fork lift truck of the type in which the thrust in the fore and aft direction and in the transverse direction is supported solely by a lift roll, the contact pressure of the lateral side of the outer race with respect to the pressure-receiving section is adjusted by an adjustment screw.

Abstract: A fluid-operated cylinder to be used as a load lifting cylinder includes a cylinder casing defining a cylinder bore between two opposed ends, one of which ends is provided with a fluid supply/discharge port, a piston unit having a piston element and a piston rod, the piston unit being axially movably arranged in the cylinder bore of the cylinder casing, and a flow rate control valve unit axially movably mounted in the piston element so as to cause a gradual change in a flow rate of working fluid throughout a predetermined amount of piston stroke when the piston unit starts to move out of the cylinder casing and comes to a stop at a bottom position in the cylinder casing, thereby cushioning shock occurring in the fluid-operated cylinder.

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.
