Abstract: An assembly kit for cable winches, comprising a cable drum, a drive motor, a transmission unit, and a supporting frame, where the assembly kit includes various transmission housing parts for the transmission unit in order to enable the assembly of a cable winch in a C shape or in a quasi-coaxial shape. A method for converting a cable winch, comprising a cable drum, a drive motor, a transmission unit, and a supporting frame, between a C-shape arrangement and a quasi-coaxial-shape arrangement, for which purpose the transmission unit, in the case of the use of different housings, in particular specific housing shells that can be assembled in order to form the different housings, is assembled differently for the C shape or coaxial shape while the same parts, in particular identical shafts, are used within the particular housing.

Abstract: A trolley for a lifting device with lifting gear arranged on a support frame and wheels which are mounted on the support frame, via which the trolley can be moved on a support, and at least one first wheel of which is mounted on an axle. The axle can be driven together with the wheel by means of a drive motor. The trolley provides a reliable transmission of drive forces between the wheels and the rail with the drivable first wheel connected to at least one of the other wheels in a driving manner via a flexible drive such that the axle is arranged between the drive motor and the flexible drive and thus the flexible drive is connected downstream of the axle in a driving manner so that the flexible drive can be driven by the axle.

Abstract: A pulley block for tackles has a pulley surrounded by a covering hood having inlet and outlet openings for a load cable, with a covering element inserted into at least one of the openings and retained by a retaining strip reaching behind an edge of the opening. The covering element has an opening for the load cable that is less than the inlet and outlet opening in the covering hood. The covering element is divided into first and second covering parts such that to mount the covering element on the covering hood with the load cable in a reeved state, the first and second covering parts can be inserted into the inlet and outlet opening via the retaining strips of the first and second covering parts, then reach behind the edge of the inlet and outlet opening, and then be joined to form the covering element in a mounted state.

At least one of the braces is designed flatly and has a main surface which extends transversely to a longitudinal direction of the crane girder. The brace is removably secured to the upper chord and/or the lower chord.

Abstract: A lifting apparatus, especially a cable traction mechanism, comprising a base frame that has at least two base plates, further comprising at least two longitudinal beams which have a first end and an opposite second end and which interconnect the base plates and keep the same apart from each other. The lifting apparatus, especially a cable traction mechanism, comprises a simple design and can readily be mounted, dismounted, or modified by detachably fastening the first end and the second end of the longitudinal beams to the base plates in such a way in an operational state of the lifting apparatus and designing one of the at least two base plates in such a way that the longitudinal beams can be inserted or removed in the direction of the longitudinal axis thereof when mounting, dismounting, or modifying the base frame.

Abstract: A lifting apparatus, especially a cable traction mechanism, comprising a base frame that has at least two base plates, further comprising at least two longitudinal beams that interconnect the base plates and are spaced apart from each other, and at least one attachable cross-member for cable reeving parts that is fastened to the base plates and extends substantially parallel to the longitudinal beams. Multiple mounting points, to which the attachable cross-member for cable reeving parts can be alternatively and detachably fastened, may be arranged on each of the base plates to promote modularity of the lifting apparatus.

Abstract: A lifting apparatus, especially a cable traction mechanism, comprises a base frame that has at least two base plates and at least two longitudinal beams that interconnect the base plates and are spaced apart from each other. Attachment elements are mounted on the base plates by means of holding parts. The lifting apparatus, especially a cable traction mechanism, is characterized by a modular design, where the holding parts are arranged as extensions of the longitudinal beams.

Abstract: A brake for a hoist, includes a brake disk and a magnetic filed which is aligned transversely to the brake disk and generates a reactive force which inhibits a movement of the brake disk and is dependent on the rotation speed of the brake disk as well as a radial distance from the rotation axis. The magnetic field is formed by two magnetic poles arranged on both sides of the brake disk.
