Container-handling vehicle

A container-handling vehicle for picking up storage containers from a three-dimensional grid of an underlying storage system includes a vehicle body and at least one lifting device. The lifting device includes a lifting shaft assembly including a lifting shaft and at least one motor for rotating the lifting shaft, a lifting frame for releasably connecting a storage container, and a first pair of lifting bands and a second pair of lifting bands connecting the lifting shaft to the lifting frame. The lifting shaft includes a first end section and a second end section. Each lifting band has a first end and a second end connected to the lifting shaft and a corresponding lifting band connector on the lifting frame, respectively. Each pair of lifting bands has a first lifting band connected at the first end section of the lifting shaft and a second lifting band connected at the second end section of the lifting shaft. The first pair of lifting bands extends in a substantially horizontal direction from the lifting shaft towards a band guiding assembly, the band guiding assembly is arranged to change the direction of the first pair of lifting bands to extend in a vertical direction. The second pair of lifting bands extends in a vertical direction from the lifting shaft at the side of the lifting shaft facing away from the band guiding assembly, and the connections between the first ends of the first pair of lifting bands and the lifting shaft is staggered by 75-105 degrees relative the connections between the first ends of the second pair of lifting bands and the lifting shaft.
