Abstract:
An apparatus for controlling pivoting of an industrial vehicle axle, the axle being pivotally supported with respect to a body of an industrial vehicle, wherein the apparatus comprises:a fluid pressure damper arranged between the axle and the body to connect the axle to the body, wherein pivoting of the axle is permitted when the flow of fluid through the damper is allowed, and pivoting of the axle is restricted to lock the axle when the flow of fluid through the damper is prohibited;a fluid passage connected to the damper; anda valve for selectively opening and closing the fluid passage to selectively allow or prohibit the flow of fluid through the damper, wherein the valve repeats a valve cycle, each valve cycle comprising opening the valve to open the fluid passage and closing the valve to close the fluid passage, to regulate the amount of fluid that flows through the fluid passage and thus limit the pivoting speed of the axle to a first predetermined value or lower when the axle is released from a locked state.
