Abstract: A cellular depot including a plurality of cells facing onto a corridor through which runs at least one motor-driven car to convey loads between the cells. The car includes a trolley which is motor-driven to move between the car and the inside of a cell and transfer a load stored or to be stored to and from the car and cell. The trolley includes a hydraulic drive connected, for their power supply, to an independent source of fluid under pressure, which is automatically recharged when the trolley is accommodated on the car.

Abstract: A supporting device (10) for overhead runways comprises a fastening and adjusting coupling for connecting a bracket (12) (the lower end of which is secured to the rail (13)) to an upper suspension beam (11). The coupling comprises a first (20) and a second (23) element for connecting the beam to the bracket, the first element defining a circumferential rim (19), two parallel plates (14, 15) being interconnected by bolts (16, 17, 18) which reciprocally close together to grip the circumferential rim between the plates thereby enabling the reciprocal rotation of the element and plates around a vertical axis. The plates (14, 15) are adjustably connected to the second element to allow adjustment of the reciprocal gap between the first and second elements.

Abstract: A conveyor system for moving loads, comprises including an overhead rail (11, 211) along which run motor-driven carriages (10), each carriage having a motor-driven wheel (13, 113, 213, 313, 413, 513) resting on the upper part of the rail and a frame (12, 15) ending on the lower part of the rail with a device (16) for supporting a load. The wheel (13, 113, 213, 313, 413, 513) has a rolling surface (22, 122, 222, 330) which rolls over a corresponding rolling surface (25, 129, 225) on the rail and also a gripping surface (23, 123, 223, 330) which grips a corresponding gripping surface (24, 128, 224, 324, 424, 524) of the rail. One of the gripping surfaces (23, 123, 223, 330 or 24, 128, 224, 324, 424, 524) has rigid gripping teeth (23, 123, 224, 330, 430, 530), while the other of the gripping surfaces (24, 128, 224, 324, 424, 524 or 23, 123, 223, 330) is made of elastically pliable material in order to receive an imprint of the teeth.
