Gantry cranes or Goliath Cranes are very versatile cranes used typically for activities in steel warehouse, precast yards, construction sites, port, train station, powe plant and other outdoor applications.
Include single girder gantry crane, double girder gantry crane, semi gantry crane, trussed gantry crane. Suitable for indoor and outdoor usage.
These cranes can be completely customized for SWL, span, lifting height, speeds, control method and class of duty to suit the actual applications.
Dafang provide single girder gantry crane solutions from 1 Ton SWL up to 20 Ton SWL (we also manufacture gantry crane designed according to client special requirement).
According to different situations, single girder gantry crane have three type: L single girder gantry crane, MH single girder gantry crane, truss type single girder gantry crane.

When export gantry crane, to largely save sea freight, our engineer will try to reduce the goods volume. The support beams is dismountable.
Ground Beam connect with support legs, travelling on the floor rail. Ground beam use reliable motors, ensure stable travel.
Support legs support the main beam and lift mechanism. It can be box type and trussed type due to different use situation
Maintenance cage is a small mechanism, workers can stand on this cage and offer repair or maintenance for crane
Q235/Q345 carbon structural steel. Strong box type with standard deflection. If deliver by container, then need to divide the main beam.
Light capacity equipped with general LD wheel, heavy capacity equipped with high quality forged wheel or wheel group
Crane leg is ‘L' type, is it more convenience for large size goods from middle position move to cantilever without any dimensional limit of support leg.
Crane can equipped withtwo type lifting mechanism, one is steel wire rope hoist, hoist traversing under the main girder, the other one is trolley, trolley traversing on the main girder.
