Abstract:
An industrial vehicle including a hydraulic resistance device for resisting the movement of an axle of the industrial vehicle with respect to a frame of the industrial vehicle, wherein the device is connected to a hydraulic circuit for regulating the behavior of the device, the industrial vehicle comprising:a planar engagement surface located on one of the axle and the frame;a cylinder body fixed to the other of the axle and the frame, wherein a hydraulic chamber, which contains hydraulic fluid, is defined within the body;a piston located in the chamber;a piston rod connected to the piston, wherein the piston rod protrudes from the body toward the engagement surface, wherein the piston rod rotatably supports a rotating member at its distal end for contacting and rolling on the engagement surface such that, when the industrial vehicle travels, at least at certain times according to the state of the hydraulic circuit, the rotating member is permitted to roll along the engagement surface when the axle pivots with respect to the frame, and wherein pivotal movement of the axle toward the frame causes the piston to apply pressure to the hydraulic fluid within the chamber.
