Workstation cranes are a type of bridge cranes or overhead traveling cranes that are used to lift and move light to moderate weighing loads within a work area. These cranes consist bridge or girders, hoisting trolley, rope and poles. Work station cranes are specially designed to meet the demands and requirements of workstations and production lines that need machine with 2000 kg of lifting capacity. These cranes can be ceiling mounted or freestanding on the floor, which can be operated electrically or manually. Manually operated work station cranes are propelled by the hydraulic pump system.
Different types workstation cranes are Free standing work station cranes, Wall mounted workstation jib cranes, Wall mounted workstation bridge cranes and Work station monorail cranes.
Prime Components :
Various components of a Workstation Crane are as follows:
End stop bumpers – These are mainly used for enclosing tracks to stop the movement of hoist trolley. End stop bumpers have rubber coating for increased impact resistance.
Festoon sections – These are bolted onto an end of a runway to allow stack up of cable/ hose trolleys.
Cable/Hose clamps – These are attached to one end of the runway ( festooning section) and one end of the bridge.
Cable/Hose Trolleys – These have four wheels, which ensure easy movement of loads.
Flat cable festooning system – These are used to manage cables and hoses which provide power or necessary gaseous/liquid media for moving cranes.
End trucks – These carry the bridge along the runways. End trucks guard against crabbing of the workstation bridge cranes.
Hoist trolleys – These have sets of wheel, which allows the horizontal movement of hoisted loads.
Track Options in Workstation Cranes :
Workstation cranes are also available with varied track options like:
Alu Track – These are enclosed tracks, which are made from aluminum. Alu-Tracks reduce the overall system weight, so that bridge cranes can be operated more smoothly.
Steel Tracks – These tracks are made from high quality stainless steel, which gives these tracks an extra strength and durability.
Trussed Steel Tracks – The trussed steel tracks are used for longer span in locations where repeated support points are not available.
Application areas :
These are widely used in various sectors and industries such as:
