    Abstract: A refuse handling device for moving a refuse receptacle (12) between a lower level and a higher level and for emptying the receptacle at the higher level by tipping the receptacle, includes a cradle (11) for carrying a receptacle. A driving arrangement (9) lifts and lowers the cradle and also a device (31) for turning the cradle between an upright receptacle position and a receptacle emptying position. The cradle (11) is carried by an axle, which may be raised and lowered transverse to its longitudinal direction and which is rotatable. At its ends the axle has wheels (8), which are non-rotatably connected to the axle. Each of the wheels is rotatably journalled in a respective car (6, 7) for running in a respective elongated guide device (25). The cars are driven by a driving arrangement (9) by it being subjected to a force which is directed mainly in the longitudinal direction of the guide arrangement, thereby causing the lifting and lowering motion.
