Industrial truck i.e. counterbalance fork-lift truck, for in-plant goods transportation, has recognizing unit to recognize roadway bumps with significant extension in driving direction of truck, where bumps are present lateral to truck

摘要

The truck i.e. counterbalance fork-lift truck (1), has a recognizing unit to recognize roadway bumps e.g. pits, steps and edges, with significant extension in a driving direction of the truck, where the bumps are present lateral to the truck. The recognizing unit has a device including ultrasonic sensors (11a, 11b) for determining distances. The device has a sensor e.g. infrared sensor, for detecting electromagnetic waves. The recognizing unit is in effective connection with a signaling device for outputting acoustic, optical and/or haptic signals.
