Double girder gantry crane, suitable for open freight yards and along railway operations, because its large leg space, it is suitable for lifting large volumes of goods, and also can lift containers, its gantry frame is similar with container crane.

40 Ton Double girder gantry crane design consists of gantry frame, trolley and crane long traveling mechanism, electrical system and other components. There also equipped with rail clamp, anchoring device, anemometer and corrective devices, etc. for outdoor work gantry crane.

40 Ton Double girder gantry crane design uses double beam and double track, single trolley winch structure. Crane winch trolley part include main and auxiliary hoisting mechanism, each mechanism using separate transmission set. Main and auxiliary hoisting mechanism not only can independently complete lifting, but also can be coordinated to complete the work of flipping objects.

Gantry frame structure same with A frame gantry crane, main girder, end girder, legs, saddles and lower cross beams are connected together by high strength bolts, using reaming bolts positioned on each flange plate, positioning marks have been completed before delivery. Its structure is similar with container gantry crane, which is more stable and firm.

To facilitate transport, handling and installation lifting on site, set with lugs and hanging holes on the crane main components for lifting. The intensity and location of these lugs and hanging holes are fully considering lifting safety and convenience.

40 Ton Double Girder Gantry Crane Traveling Mechanism
40 Ton Double Girder Gantry Crane traveling mechanism driving adopts motor drive the reducer through couplings and transmission shafts, reducer drive the driving wheels, which is smooth and reliable. This structural arrangement is conducive to each driving system component installation, maintenance and removal.

40 Ton Double Girder Gantry Crane Trolley
40 Ton Double Girder Gantry Crane Trolley mainly consists of lifting mechanism, trolley frame and trolley traveling mechanism.

40 Ton Double Girder Gantry Crane Hoisting Mechanism
40 Ton Gantry Crane main and auxiliary hoisting mechanism arranged in the same trolley frame, each set up with separate driving device, main and auxiliary hoisting mechanism not only can independently complete lifting, but also can be coordinated to complete the work of flipping.

40 Ton Double Girder Gantry Crane Trolley Traveling
Trolley tracks using one whole railway that joints welding as integration, to ensure the trolley running well.

Trolley traveling driving type is same with the crane long traveling mechanism.

40 Ton Double Girder Gantry Crane Technical Parameter
Technical parameter is an indicator of the operational capability of 40 Ton Double Girder Gantry Crane, main parameters including: lifting capacity, lifting height, span, working level, working speed, etc., as shown in the drawings. Complete set of supporting components (such as reducer, motor, brake, etc.) operation and maintenance, please refer to the supporting manufacturing factory manual.
