Abstract: This autonomous forklift truck (1) comprises: a lifting member (2) comprising a vertically mobile fork (4) provided with at least one arm (4a, 4b) for lifting loads, a drive system (6) for moving the truck (1), and a control unit (14) able to control the operation of the drive system (6) for autonomous guidance of the truck and able to control the vertical movement of the fork (4). The truck further comprises a device (8) for contactless detection of an obstacle mobile conjointly with the lifting member (2). The detection device (8) is able to emit a light beam sweeping at least one predefined plane detection zone to detect the presence or the absence of an obstacle. The detection device (8) is fixed to the lifting member so that the light beam passes above the transported load.

Abstract: This autonomous lift truck (1) comprises: a lifting member (2) that can move at least vertically, a drive system (6), a first contactless detection device (9), which is fixed with respect to the truck and makes it possible to detect an obstacle situated in front of the truck, and a control unit (8), which can control the truck on the basis of the information from the first detection device, and can control the movement of the lifting member (2). The truck further comprises a second contactless detection device (11), which is fixed with respect to the truck (1), arranged above the first detection device (9) and can detect an obstacle situated in front of the truck (1). The control unit (8) can control the truck (1) on the basis of the information from the second contactless detection device (11).

Abstract: This autonomous lift truck (1) comprises: a vertically mobile fork (4) equipped with at least two blades (4a, 4b) for lifting loads, a drive system (7) for moving the truck, and a control unit (9) able to command the operation of the drive system for autonomously guiding the truck and able to command the vertical movement of the fork (4). The truck further comprises a contactless load-detection device (10) able to move together with the fork and positioned above the blades (4a, 4b) of the fork. The contactless detection device (10) is able to emit a beam of light that sweeps at least a predefined planar detection zone situated above the blades of the fork so as to detect the presence of a load that is to be lifted.
