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.

Chain hoist

A running wheel block, including a housing having at least one connecting surface for connection to a supporting structure, an inwardly directed rotary bearing holding hub arranged in the housing, a rotary bearing mounted on the hub, and a running wheel mounted in the rotary bearing so that a section of its running surface projects from the housing toward at least one side. The housing is open on a side opposite to the holding hub. The running wheel encompasses the holding hub and is insertable onto or into the rotary bearing from the open side.

A running wheel block, including a housing having at least one connecting surface for connection to a supporting framework, and further having two opposing, detachable side walls, two inwardly directed rotary bearing holding hubs, arranged in the housing, rotary bearings mounted in the hubs, and a running wheel mounted in the rotary bearings so that a section of its running surface projects from the housing toward at least one side. Each of the holding hubs is arranged on one of the two opposing side walls of the housing. The housing further includes at least one spacing holder arranged between the opposing side walls. The spacing holder forms a connecting surface. The detachable side wall has centering members that, when the side wall is attached to the housing, determine the position of the holding hubs relative to the running wheel axis.

Running wheel block

A running wheel block, including a housing having at least one connecting surface for connection to a supporting structure, two inwardly directed rotary bearing holding hubs arranged in the housing, rotary bearings mounted on the hubs, a running wheel mounted in the rotary bearings so that a section of its running surface projects from the housing toward at least one side and a cover connected to the housing so as to close the housing. The holding hubs include a first holding hub that is arranged on the cover. The cover has centering members for fixing a position of the holding hub relative to an axis of the running wheel when the cover is closed.

A travelling mechanism for hoisting equipment, especially for hoisting equipment which runs on monorail flange beams that have, along with straight sections, elevated and/or laterally curved sections. The travelling mechanism has side shield members located across from one another and on each of which at least one travelling wheel is mounted as are pairs of side guide rollers between which the travelling wheels are arranged. A travelling drive and curve travelling device, which travelling device can be positioned against the monorail flange beam by springs, are also connected to the travelling mechanism. The travelling device is provided on at least one side shield member as a rotatably-mounted sprung one-armed pivot lever on an end of which an auxiliary side guide roller is rotatably mounted.
