CONTROL DEVICE FOR INDUSTRIAL VEHICLE

摘要

PROBLEM TO BE SOLVED: To improve sensing arts to decide whether an axle fixing mechanism is locked or not during turning, in an industrial vehicle having an axle fixing mechanism to support a rear axle to a machine bed by means of a center pin and lock a rear axle to the machine bed during the occurrence of an unstable factor. SOLUTION: A one-way force sensor 24 to detect a force in a lateral direction generated at a machine bed 11 during turn running is arranged on the front axle side. By detecting a force in a lateral direction to the outside widely occurring in front of the machine bed at an early time by the one way force sensor 24 when a vehicle is transferred from straight running to a turn, a threshold for decision of whether axle fixing mechanisms 21 and 22 are locked or not in correspondence to the force of a lateral direction is set to a high value and accurate axle fixing operation not to sacrifice a running feeling is practicable.
