Abstract: A shut-down buffer for a lifting device, in particular a chain hoist, includes two opposing end surfaces and at least two mutually spaced web elements extending between the end surfaces. The shut-down buffer is defined by the end surfaces, between which a through-opening for passage of a load-bearing element of the lifting device extends through the shut-down buffer.

Abstract: A load-handling crane, and a system and method are provided for operating the load-handling crane having a hoist movable by means of a drive of the crane and a handling device for operating the crane. The handling device is fastened to a liftable and lowerable suspension element of the hoist and having a sensor system for determining an orientation of the suspension element, or of a part fastened to the suspension element, or of the handling device, or of a load-handling attachment. The system further has an operating element that cooperates with the sensor system such that, when the operating element is actuated, a control command for activating the drive is able to be triggered, resulting in the hoist being movable by means of the drive in a direction of travel, with the direction of travel being dependent on an orientation determined by means of the sensor system.

Abstract: A cable winch having a base frame with at least two base plates, and at least two longitudinal beams for connecting the base plates to each other. One of the base plates is designed such that the longitudinal beams can be installed or removed in the direction of the longitudinal axis of the longitudinal beams through the base plate, with passage openings in the base plate for feeding the longitudinal beams there through, and with one beam end of each of the longitudinal beams inserted into one of the passage openings. A beam end of each of the longitudinal beams is fastened to the base plate in and against the direction of the longitudinal axis of the longitudinal beam by a retaining element that is fastened to an outer face of the base plate, wherein a separate retaining element is provided for each longitudinal beam in order to enable simple assembly, disassembly, or conversion.

Abstract: A steel product may include a metallic anticorrosion coating of an aluminum alloy. So that such a steel product possesses high media resistance, more particularly high acid resistance and corrosion resistance, the steel product may be immersed in a liquid-melt coating bath that includes an aluminum alloy. In addition to Aluminum and unavoidable impurities, the aluminum alloy may include at least one of 0.2-2% by weight Mn or 0.2-7% by weight Mg, 0.5-5% by weight Fe, and at least one of 0.05-0.4% by weight Ti or 0.05-0.4% by weight Zr. A method for producing such steel products may involve providing a steel product in a hot-rolled or cold-rolled state, activating a surface of the steel product to remove passive oxides, and coating the surface-activated steel product by immersion in a liquid-melt coating bath that comprises an aluminum alloy having the aforementioned composition.

Abstract: A cable winch, comprising an electric drive motor, a transmission, and a rotary indicator, where the electric drive motor is coupled to the transmission and the rotary indicator is associated with the electric drive motor and/or the transmission in such a way that the rotary indicator provides a signal for determining the rotational speed of the drive motor and/or of the transmission, with the rotary indicator being arranged between the electric drive motor and the transmission.
