There are various accessories required for the operation of a crane, such as slings and spare parts. The slings are produced by companies who have the specialised knowledge (e.g. about carrying capacity and security regulations) required. When old cranes are dismantled, it is possible to salvage individual components such as the beams, trolleys and chain hoists.
It makes sense to research the required parts when installing a crane, as there are particularly many slings available. They differ from each other in various characteristics including where they can be applied and their carrying capacity. Further accessories include digital or conventional crane scales, remote control, individual trolleys with a rope, engines and spare parts.
Crane accessories are used for reparation and during the operation of a crane. Crane scales are used to monitor the weight and dimensions for each construction piece. Electronic crane scales ensure that the crane does not surpass its carrying capacity.
Operating a crane scale is very simple; it is fixed between the crane hook and the sling and then displays the weight of the piece to be transported. Other pieces that belong under the category of crane accessories include sprockets, bevels, washer, axles, axle supports, guiding rollers, roller bearings, connecting flange and various bearings. The electronic equipment of a crane includes the radio control unit, combined control for tandem operation, special crane lighting systems, measuring systems, soft start devices, systems to prevent collisions, platforms and balances. Some tasks also require special pulleys, which can be produced in accordance with customer requirements. This also applies to wheels and bottom blocks. The hydraulic equipment of a crane is usually required during reparations, which includes new valves and pressure hoses. A further use of crane accessories is the correct use and supply of electricity.
Several companies have specialised in manufacturing crane accessories. Some of the most recommended suppliers include ABUS, KONECRANES, WARSTEINER EISENHAMMER, VETTER, AUMUND, DEMAG, GKS, GLOBUS, PFEIFER and SPANSET.
