Beschreibung
Zusammenfassung:	A forklift (10) comprises a main control device (31), a travel motor (41), a travel control device (43), and an object detection unit (51). The travel control device (43) controls the travel motor (41). The object detection unit (51) detects the position of an object existing in the backward direction of the forklift (10). The main control device (31) derives the expected trajectory (T) of the forklift (10). The main control device (31) imposes a speed limit on the forklift (10) by setting a vehicle speed upper limit (VS, AS1, AS2, DS1, DS2) when the object detected by the object detection unit (51) is located within the expected trajectory (T) and the forklift (10) is traveling in the direction of approaching the object. The main control device (31) gives commands to the travel control device (43) to prevent the vehicle speed of the forklift (10) from exceeding the vehicle speed upper limit (VS, AS1, AS2, DS1, DS2).
