Double Girder Overhead Crane Manufacturing

2sijos1

 

Supported on rails, double girder overhead 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 overhead cranes can be operated from the ground via cable-connected control pendant, radio remote control or from an operator’s cabin. In addition, multiple controls are possible by switching control from one mode to another. The system allows operation of the crane in a manual, semi-automated or fully automated mode.

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. Stability, a wide span and high speed represent the major advantages of this type of cranes.

double girder overhead cranes are supplied with a hook, grapple attachment, magnet or vacuum beams.

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.
