A method and apparatus for restricting pivoting of an industrial vehicle axle and maintaining the vehicle stability without sacrificing the vehicle's driving performance. Pivoting of the axle with respect to the vehicle's body is temporarily restricted in accordance with the yaw acceleration when the vehicle is turned. The acceleration value for limiting restriction is varied in accordance with the stability of the vehicle, which is determined by the state of the carried load. The limit value is relatively high when the load state causes the vehicle to be relatively stable and is relatively low when the load state causes the vehicle to be relatively unstable.

[ What is claimed is:] [14.] An apparatus for controlling pivoting of an axle in an industrial vehicle for carrying and moving a load, wherein the vehicle supports the axle such that the axle is pivotal with respect to a body of the vehicle, wherein the apparatus comprises:a yaw acceleration detector for detecting a yaw acceleration of the vehicle when the vehicle is turned;a pivot restricting mechanism for restricting pivoting of the axle in accordance with the detected yaw acceleration;a setting device for setting a yaw acceleration limit value in accordance with a current state of the load, wherein possible load states are classified into a plurality of stability ranges according to how the load state affects the stability of the vehicle, the ranges including a relatively high stability range and a relatively low stability range, wherein the yaw acceleration limit value is set at a relatively low value when the load state is in the relatively low stability range, and wherein the yaw acceleration limit value is set at a relatively high value when the load state is in the relatively high stability range;a load detector for detecting the load state; anda restriction controller for temporarily restricting pivoting of the axle when the yaw acceleration detected by the yaw acceleration detector becomes equal to or higher than the set yaw acceleration limit value, wherein the restriction controller further restricts pivoting of the axle in accordance with the result of a comparison between a lateral acceleration of the vehicle and a lateral acceleration limit value when the yaw acceleration is lower than the yaw acceleration limit value.
