QDX type European double girder hoist bridge crane adopts a unique European standard design concept, featuring small size, lightweight and small wheel pressure.
Compared with the traditional double girder crane crane, the limit distance from the hook to the wall is the smallest, and the clearance height is the lowest. The European crane is closer to the front work, and the lifting height is higher, which increases the effective working space of the existing plant. Due to the lightweight and small wheel pressure, the new plant space can be designed to be smaller and more complete. Smaller plants mean an initial investment in construction, as well as long-term heating, air conditioning and other maintenance costs can save a considerable amount of money.
The main beam is a partial rail box beam or steel beam, The end beam is made of welded steel (rectangular tube). Between the end beam and the main beam with 10.9 high-strength bolts group as a whole.
Box girder for partial rail beam or H beam structure, the steel plate welding forming
material of steel plate is Q235B / Q345B
Vertical deflection is L/800
All steel shot blasting pretreatment, achieves Sa2.5 level standard
Carefully check and clean before welding steel, usually by the automatic welding machine for welding (MIG or semi-automatic welding)
All weld for X-ray nondestructive flaw detection
A beam of rectangular steel pipe or welding forming in the numerical control machine tool processing forming at a time, the material of steel plate Q235-B
Each end beam is equipped with double rims of wheels, buffers and derailment protection devices
the maintenance platform (maintenance walkway) of the double-beam crane is installed on the driving side of the crane in the direction of the main beam
The main beam and the end beam are connected with 10.9 high-strength bolts to ensure the precision and smooth running of the whole machine.
Lifting Mechanism
QDX European double girder electric Wire Rope Hoist. The most advanced lifting mechanism, good performance of maintenance free (Please refer to QDX European double girder electric wire rope hoist).
Safety Protection
Safety device
Anti-falling protection for the Three-in-One electric motor of the trolley and crane prevents accidental falling
Rain Cover: For lifting mechanism of outdoor cranes, electric cabinet and driving mechanism
