Abstract: The invention concerns a suspension for load hooks, especially for lower blocks of cable controls, with a shaft mounted in a recess of a carrier body and able to turn about a vertical axis, which is mounted in a continuous bore of a support element and thrusts against the carrier body by means of at least one axial bearing. In order to create a short and simple construction of a suspension for a load hook, the invention proposes that the shaft of the load hook is mounted in the carrier body by a bearing arrangement consisting of the support element, at least one axial bearing, and the retaining ring surrounding the shaft, and the bearing arrangement is secured by a fastening element, especially a snap-ring, in the carrier body.

Abstract: A lifting apparatus includes two parallel longitudinal members interconnected by at least one connecting element. A lifting beam is movable by a drive mechanism along the longitudinal members and supports, directly or indirectly, a handling device. Extending parallel to and supporting the lifting beam is a guide rail, which is received in spaced-apart carriages, for displacement in longitudinal direction in a freely running manner, as the lifting beam is moved by the drive mechanism. The carriages are arranged in a space between the longitudinal members and secured to the connecting element, wherein the longitudinal members and the lifting beam are formed with longitudinal grooves for engagement of sliding blocks so that the connecting element, the drive mechanism and the carrying unit are securable to the longitudinal members in any desired longitudinal position, and the guide rail is securable to the lifting beam in any desired longitudinal position.

Abstract: A torque support, especially for wheel blocks, is arranged between a gear unit housing with a drive shaft and a driven unit housing. The torque support includes a plate-shaped base body which is detachably fastened to the gear unit housing with fastening elements. The plate-shaped base plate has at least two fastening locations comprising through openings for fastening the torque support to the driven unit housing. To keep the shearing forces resulting from the torque support and acting on the gear shaft small while the torsional moment is simultaneously absorbed with low play and in such a way that load peaks are damped, a corresponding plastic ring body is inserted into each through-opening in a positive-locking engagement. A side of the plastic ring body facing the driven unit housing has an edge area which widens radially outward forms an elastic disk element arranged between the driven unit housing and the torque support.

Abstract: A securing ring, includes a body defining a ring opening and having a circumference of substantially circular configuration at formation of a slotted gap to define confronting ring ends. The body defines a ring plane and an axis of symmetry and has a radial width which continuously increases, at least in sections, from the ring ends onwards at both sides of the axis of symmetry. Each of the ring ends has a L-shaped configuration and is extended by a lug jutting out from the ring plane and formed with a throughbore. Both lugs of the ring ends are positioned on a same side of the ring plane, with the throughbores of the lugs extending in parallel relationship to one another and to the ring plane.

Abstract: The invention is directed to a running wheel for traveling units which are movable on rails, especially for traveling cranes. The running wheel includes an outer running ring, a resilient damping hub inserted in central opening of the running ring. The hub transmits torque received from a drive shaft to the running ring. The resilient damping hub effectively intercepts occurring torque peaks forward of the gear unit and drive shaft, by elastically deforming while maintaining a connection at the central opening of the running ring without play.

Abstract: The invention relates to a robot arm with a work arm connected to it, a connector moved by motors for tools, workpieces, workpiece grippers or gripper change systems, whereby the motors are located at the end of the work arm opposite the connector, and are connected by output connections with gear wheels mounted in a swiveling axis of a swiveling head of the connector. To make such a robot arm flexible, and moreover to guarantee that the work arm is rigid, it is proposed that the axes (D,E,P) of rotation of the elements (work arm 2, swiveling head 23, connector 3) intersect at a common intersection point (A).
