An industrial vehicle remote control system includes a forklift that has a vehicle communication unit and a remote control device that has a remote communication unit and is used to remotely control the forklift. A vehicle wireless CPU of the industrial vehicle remote control system acquires the received radio wave intensity of a remote control signal by which the two communication units wirelessly communicate, and, on the basis of the results thereof, determines whether the forklift is positioned in a permission range or in a prohibition range.

An industrial vehicle remote operation system includes an industrial vehicle including a vehicle communication portion, a communication device, and, a first signal conversion portion. The communication device includes a reception portion that receives two or more types of operation signals, an obtainment portion that obtains a conversion program for converting the operation signal into the remote instruction signal, a storage portion configured to store the conversion program, a second signal conversion portion configured to convert the operation signal into the remote instruction signal using the conversion program, and a communication device communication portion that sends the remote instruction signal to the vehicle communication portion. The communication device includes an update portion configured to update information stored in the storage portion so as to enable addition, deletion, or change of one or more of the operation signals that are convertible by the second signal conversion portion.

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.
