A method for monitoring a chain hoist having an electric drive motor which is connected on the output side, via a friction clutch, to a transmission, wherein, via a sensor, a speed of the transmission is sensed, and the sensed speed of the transmission is compared with an operating speed of the drive motor by means of a control device. In order to achieve safe and efficient operation of the chain hoist, a vertical position of the load handling device of the chain hoist is also determined by means of the control device. The invention also relates to a chain hoist having a control device which is designed and configured to carry out the method according to the invention.

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.

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.

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.

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.

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.

Lifting device, in particular a cable winch

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.

A running gear, for example, a single-rail lower-flange running gear for hoisting equipment, includes several wheels running on a rail, at least two of which are arranged one behind the other in the direction of travel of the running gear and adapted to be driven by an electric motor. The driven wheels are joined to at least two shafts, which are oriented coaxially to the axis of rotation of said at least two driven wheels.

A chain block with a drive motor () with a motor shaft (), which is connected at the take-off side via a slip clutch () to a transmission input shaft (), having a first gear () and mounted in a housing () by pivot bearings (), of an at least one-stage transmission (). In order to create a simple design of chain block with a slip clutch, the transmission input shaft () is to be mounted floating in the pivot bearings () in order to change the frictional force of the slip clutch ().

Chain block

A chain block with a drive motor () and with a transmission (), connected to the drive motor () at the take-off side, with a transmission output shaft (), on which a chain wheel () is rigidly arranged for pulling a chain. In order to create a compact chain block, the chain wheel () faces the drive motor () at its take-off end face () and the outer circumference of the chain wheel () reaches into the imaginary extension of the outer contour of the drive motor ().

A chain hoist, includes a chain which is trained over first and second sprockets defining a movement path for the chain, with the first sprocket being connected to a load-bearing member, and with the second sprocket being part of a drive unit for operating the chain. In order to effectively prevent chain vibrations caused by the so-called polygon effect, the chain hoist includes a damping unit which is positioned in the movement path of the chain for damping vibration.

Pivot-hung door drive system with an electronic control system that contains at least one memory and one microprocessor, for an at least single-panel door, the door panel of which is driven by an electro-mechanical drive unit that acts in the opening and closing directions. The drive unit consists essentially of a drive motor with a transmission and a power transmission unit for the door connected to it, whereby the power transmission unit consists of a drive shaft which is connected with one end of an actuator lever and the pivot-hung door drive system is installed inside a door panel or inside a door frame or casing. The power transmission unit consists of a screw with a nut that partly surrounds it, which nut is positively and non-positively connected to a toothed rack, whereby the drive shaft is engaged with its gear teeth in the gear teeth of the toothed rack.
