Driverless transport device with adjustable width function

Abstract

The invention relates to a driverless transport device for the automatic, space-saving and collision-free picking-up, transport, lifting and delivery of pallets closed at the bottom and pallets open at the bottom, wherein the wheel arms of the chassis, which is substantially U-shaped in plan view, can be displaced transversely together or independently of one another relative to the base unit or to the lower part of the base unit of the transport device and can be positioned in a first position in alignment below and in a second position laterally outwardly spaced from the lifting fork tines in the width of the transport device, wherein the lifting fork tines are movable with the lifting fork back independently of the wheel arms relative to the base unit or to the lower part of the base unit independently of the wheel arms, and the transport device can be moved omnidirectionally along any trajectories from any first point to any second point. In this way, pallets open at the bottom, the width of which is smaller than the width of the transport device, can be picked up or deposited flush, e.g. laterally on the inner walls of loading containers or other lateral boundary surfaces, without collision. The driverless transport device according to the invention is particularly light, requires no counterweight, has the lowest possible energy consumption and the lowest possible space requirement and requires no additional equipment.
