Boom cylinder stop for the lift cylinders of a skid steer vehicle

摘要

A boom stop having a elongated tubular body portion is mounted on the rod end of one of the hydraulic lift cylinders of a skid steer loader. When the boom of the skid steer loader is lifted, the boom stop is carried outwardly with the rod end of the cylinder, the opposite end of the boom stop dropping into a plane adjacent the rod end of the cylinder when the hydraulic cylinder is almost fully extended. Thus the boom stop is interposed between the outer end of the cylinder body and the rod end of the cylinder to retain such lift cylinder in an extended position under loading conditions. A projection provided at a lower end of the boom stop carries a toggle mechanism mounted on a pivotal connection, the mechanism including a ramp like projection which rotates downwardly when the cylinder is extended further outwardly to disengage the stop from the cylinder body, the ramp engaging both the cylinder body and the body portion of the stop to slide the body portion of the stop onto the cylinder body when the cylinder is pulled back to a fully retracted position.
