Abstract: An industrial vehicle includes: a steered wheel angle control unit for changing a steered angle of rear wheels so that an angle of a steering handle corresponds to an angle of the rear wheels, based on signals from a steering angle sensor and a steered wheel angle sensor; an angle calculation unit configured to calculate an angle of the rear wheels corresponding to a minimum turning radius at which a vehicle does not turn over based on the gravity center height and a speed of the vehicle; a steered wheel angle limitation unit and a steering angle limitation unit configured to limit and control the angle of the rear wheels based on an angle of the rear wheels corresponding to the minimum turning radius; and a warning notification unit configured to execute a warning notification based on the angle of the rear wheels corresponding to the minimum turning radius.

Abstract: Provided is a forklift capable of recognizing an approximate weight of an object to be conveyed supported by a fork without adding special parts. A control unit includes a storage unit which stores load/time information indicating a relationship between a delay time required for an angle of rear wheels to reach an angle corresponding to an angle of the steering wheel and a weight of the object to be conveyed supported by the fork at that time, a delay time detection unit which detects the delay time required for a steering angle of the rear wheels to reach the angle corresponding to the angle of the steering wheel, and a weight identifying unit which identifies the weight of the object to be conveyed supported by the fork on the basis of the delay time detected by the delay time detection unit and the load/time information stored in the storage unit.
