Girders are large beams utilized in heavy constructions, like bridges, buildings, and tunnels. However, because they’re a special sort of beam that gives horizontal support and may bear both dynamic and static loads, they can also be utilized in heavy-duty lifting equipment like girder cranes.
Differences Between Single Girder and Double Girder Cranes
Two of the foremost common cranes for lifting heavy materials are single girder and double girder variations. Both of those cranes are overhead cranes — or, more specifically, bridge cranes, which have horizontal runways and a traveling bridge with a hoist. These cranes can operate quickly and sometimes are often controlled by a foreign system. Single girder cranes have one girder along which the hoist travels, whereas double girder cranes have two parallel girders that the hoist runs between.
While both single girder and double girder cranes are strong and sturdy, they provide different lift and height capabilities. On single girder cranes, the hoist hook is attached below the girder with the assembly attached to the underside, which removes a possible 18 to 36 in. from its vertical lifting capacity. But in double girder cranes, the hoist is within the same plane because the girders and therefore the hoist assembly is attached along the highest of the girders, leading to higher lift capabilities of taller loads.
Double girder cranes are also preferred for very heavy duty and severe duty. This isn’t because double girder cranes have more power or duty classification. Instead, it’s because the double girder cranes tend to possess more specialized equipment. Double girder cranes more practically incorporate a service platform for technicians to use also.
