Abstract: The invention relates to a loading platform (2,3) for displacing goods, comprising a support frame for goods (8) and at least one double roller device (7,9) arranged in longitudinal direction, wherein the double roller device comprises a number of first roller elements (9) situated at regular mutual distances and having a rolling surface (15), and a number of second roller elements (7) situated above the first roller elements and having a rolling surface (15), and wherein the rolling surface of the first roller elements lies against the rolling surface of the second roller elements, characterised in that the roller elements engage movably on the frame in vertical direction.

Abstract: A loading device is disclosed for transferring a cargo onto a mobile loading floor. The loading device includes a frame having a carrying surface wherein the carrying surface has a longitudinal direction and wherein the frame is also provided with a support device for supporting the loading device on a ground surface. The loading device is provided with an adjusting device for aligning an outer end in the longitudinal direction of the carrying surface. An auxiliary transport device is further disclosed for loading and unloading cargo in a vehicle.

Abstract: The present invention relates to a method for forming weakenings in a metal plate (8), comprising of: deforming the metal plate to a predetermined depth to form a weakening thinned portion along at least one line; and bending the metal plate along the line, characterized by displacing relative to each other the metal plate and at least one tool deforming the metal plate along the line and over at least one surface of the metal plate with a force directed substantially transversely of the metal plate and sufficient to deform the metal plate. The invention also relates to a device for performing thereof.

Abstract: A hydraulic device comprising at least two cylinder-piston assemblies. Each of the assemblies are of the double-action type with a front and rear chamber on either side of a piston. The chambers are connected in series in a hydraulic control circuit such that the front chamber of a first assembly has a direct connection to a rear chamber of a second assembly. At least one of the cylinder-piston assemblies is provided with a valve assembly which opens a bypass thereby bypassing the piston of the assembly when the piston is situated close to the direct connection at the end of its stroke and the effective piston surfaces are the same in the chambers mutually connected by the direct connection.

Abstract: A bulkhead is formed of a sheet of material which is preformed so as to have alternatingly opposed S-shaped creases at spaced intervals which define pairs of mutually facing recessed grooves between adjacent creases. Resilient surface area enlarging members are each provided with a pair of lips formed on the opposite edges thereof. Each pair of lips are received within a pair of mutually facing recessed grooves of the bulkhead. The surface area enlarging members can be snapped into or out of operative position with respect to the bulkhead to adjust the surface area of the device.

Abstract: A fork lifter comprising a mobile frame, a pole arranged on the frame and a load carrier adapted to move up and down along the pole and having a fork protruding from the pole, the prongs of the fork being provided with extensible parts wherein the extensible parts are driven by at least two cylinder-plunger combinations accommodated in the prongs of the fork and being located in a substantially horizontal plane.
