<p>The level control for a double axle elevator platform has a frame (1) with pivoted axles (2,3). A fluid cylinder (6) is pivoted between one axle (2) and the chassis (1). A second cylinder (7) is pivoted between the chassis and the rear axle (3). The two cylinders are connected in parallel on the same control circuit (12). The pivot points of the cylinders to the axles are at the same spacing from the longitudinal axis of the platform</p> |
