Double girder overhead crane manufacturing

Double girder overhead cranes - supported on rails, can easily transport heavy loads weighing up to 200 t.

Double girder overhead cranes

Supported on rails, double girder bridge cranes can easily transport heavy loads weighing up to 200 t. The crane has a span up to 40 m and the maximum lifting height H = 50 m. Cranes can be used for indoor and outdoor service at room / ambient temperatures ranging from -20°C to +40°C. This type of crane has a high resistance to horizontal loads.

Double girder bridge cranes can be operated from the ground via cable-connected control pendant or radio remote control. In addition, multiple controls are possible by switching control from one mode to another. Cranes can be supplied with one or two loading trolleys based on the number of trolleys used. A trolley can feature a primary or assistance lift function. These cranes can be supplied with a hook, grapple attachment, magnet or vacuum beams.

The system allows operation of the crane in a manual, semi-automated or fully automated mode.

The crane can be provided with custom service platforms, maintenance walkways and auxiliary lifting equipment. The crane itself can be manufactured with explosion-proof installations.

1. Lifting capacity Q = max 200 t
2. Span La = max 40 m
3. Base A = relative to Ls
4. Hook height H = max 50 m
5. Extreme positions of the hook L1 and L2 = relative to the hoist design
6. Distance between the runway rail and the hook H1 = relative to the bridge and hoist design
7. Distance between the runway rail and the bridge H2 = relative to the bridge and trolley design
