Abstract
A forklift truck includes a two-dimensional rangefinder, a mover device, a calculator, and a determiner. The two-dimensional rangefinder emits a measurement wave in a downwardly inclined direction from above and toward a first load and measures a distance to a measurement point located on a surface of the first load. The mover device moves the two-dimensional rangefinder. The calculator calculates a longitudinal distance between the emitting source and the measurement point. The determiner determines that the first load is in a condition in which there is a level difference between a front part and a rear part of an upper surface of the first load, and the front part is higher than the rear part, when a variation in the longitudinal distance that is generated in response to a displacement of the two-dimensional rangefinder moved by the mover device exceeds an upper limit of a specified threshold range.
