Gantry crane, types of gantry crane designs, Dongqi Gantry Crane

 A-type Gantry crane consists of gantry frame steel structure, trolley, crane traveling mechanism, electrical system and other major components.

To facilitate transport, loading, unloading and installation on site, on the main components set up lugs, hanging holes, etc., used for lifting. The intensity and location of these lugs and hanging holes fully consider lifting safety and convenience.
Crane machine technical parameter is an indicator of the operational capability of the crane, its main parameters including: lifting capacity, lifting height, span, working-level, working speed, etc., you can check the general drawing. Various components (such as: reducer, motor, brake, etc.) operation and maintenance, please refer to the manual.

 U-type Gantry Crane

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

U-type Double Girder Gantry Crane with mature technology, it is safe, reliable, easy to operate and running smooth, it is our company's mature product over the years, as the most widely used cranes in China now.
U-type double-girder gantry crane mainly consists of gantry frame steel structure, trolley and crane traveling mechanism, electrical system and other components. Outdoor work crane also installed with rail clamp, rail anchor device, anemometer, corrective devices, etc.

U-type double girder gantry crane uses double-beam and double-track, winch single trolley structure. Crane winch trolley part is including main and auxiliary hoisting mechanism, each using a 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.

 

L Type Gantry Crane

L-type gantry crane is single girder Gantry Crane; with large net space due to L-shaped structure. With light weight, low overall height; the structure is compact, more cost savings, and it is cost-effective gantry crane with respect to A-type and U-type gantry crane. Maximum lifting capacity is of 50 tons. Widely used in open-air yards, docks, along railway operations and other places.
L type single girder gantry crane mainly consists of the L-shaped bridge frame, traveling mechanism, trolley parts, electrical control system and other components.
Gantry frame steel structure of L-type single girder gantry crane mainly consists of the main beam, L-type legs, lower cross beam (crane traveling parts) and other components. Connection by high strength bolts.
Crane traveling parts included in the lower cross beam, motor drive through reducer, with reasonable structure, smooth operation.
