    摘要: 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.

    摘要: 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.
