A forklift has a frame and a rear axle, which is pivotally joined to the frame about a center pivot axis. Front and rear supporting members support the frame on the axle. A damper is located between the frame and the axle. The damper has an upper end connected to the frame and a lower end connected to the axle. A bracket for joining the upper end of the damper to the frame is located no further forward than the front end of the front support member and no further rearward than the rear support member. This structure suppresses torsion and bending force applied to the damper.

Installation position of a damper for industrial vehicles

A structure for supporting a hydraulic cylinder that controls pivoting of a rear axle in a forklift. The rear axle is supported pivotally to the body. The hydraulic cylinder connects the rear axle to the body. Two hydraulic oil chambers are defined in the hydraulic cylinder. Movement of hydraulic oil between the oil chambers is selectively permitted and prohibited to selectively permit and prohibit pivoting of the rear axle. The body includes a pair of side frame members located on the sides of the body and a pair of cross frame members connected to the side frame members. The rear axle is located under the cross frame members. One end of the hydraulic cylinder is pivotally connected to the cross frame members by an upper joint. An upper pin, which is part of the upper joint, is directly supported by the cross frame members. Accordingly, an exclusive bracket for coupling the hydraulic cylinder to the body is not necessary. This simplifies the structure for coupling the hydraulic cylinder to the body.
