An apparatus for controlling pivoting of a forklift rear axle (10). A hydraulic damper (13) is arranged between a rear axle (10) and a forklift body (1a). The damper (13) includes two oil chambers (R1, R2). The oil chambers (R1, R2) are connected to a first passage (P1) and a second passage (P2). A two-way switch valve (14) is arranged between the oil chambers (R1, R2). The valve (14) permits the flow of oil between the oil chambers (R1, R2) and allows pivoting of the rear axle (10) when opened. The valve (14) restricts the flow of oil between the oil chambers (R1, R2) and prohibits pivoting of the rear axle (10) thereby locking the rear axle (10) when closed. When the rear axle (10) is released from a locked state, the valve (14) repeats a valve cycle, which includes opening and closing the valve (14), to regulate the amount of fluid that flows between the chambers (R1, R2). The valve (14) is then kept in an opened state. This prevents shock that may be produced by sudden tilting of the body (1a) when the rear axle (10) is released from a locked state. <IMAGE> |
