Description:
1. The double girder overhead bridge crane main girder made of computer-optimised box sections, end carriages are made of torsionally rigid, welded box-section design.
2. The modular design uses a combination of high-quality parts and serial modules to form a rich product specification, modularization, standardization, and mass production mode to ensure product quality, shorten manufacturing period, easy transportation and installation.
3. By using compact hoist and high strength materials, the crane has much smaller sizes, wheel load and weight.
4. Compact structure, low clearance, small dimension and large work scope, improving production efficiency.
1. Advanced steel plate pretreatment production line for shot blasting, painting and drying.
2. The double girder overhead bridge crane main girder, end carriages and trolley frame adopts our robot automatic welding technology, automatic double-sided intermittent welding technology for the reinforced angle steel weld on the main beam cover web and gantry submerged arc welding for longitudinal weld on the outside of the main beam, all ensuring the highest welding quality.
3. The industry leading technology and application of modular interchangeability of crane main girder and end beams.
4. The industry leading crane bridge frame and trolley frame processing technology after welding, achieving the high efficiency and stable processing accuracy of the overall crane processing technology after welding.
5. The industry leading automatic spraying production line includes three workshops of sandblasting, painting and drying. Safety, reliable and environmental.
Germany ABM Hoist lifting motor double-winding squirrel-cage pole-changing dual speed hoisting motor with stable and reliable operation, and free of maintenance.
Safety monitoring systems for hoisting and travelling mechanism, many functions can be achieved according to the demands of users.
1. Compute the rest circles of safety work of hoisting mechanism.
2. Accumulated working time for hoisting.
3. Accumulated overload times,
4. Accumulated start up times of hoisting motor.
5. Over-heat protection of hoisting motor and alarm.
6. Overload protection and alarm.
7. Brake pad thickness alarm.
8. Display fault information and maintenance tips.
The double girder overhead bridge crane provides with many protection including linkage, overload protection, zero protection and limit protection, ensuring the crane always under safety operation.
The double girder overhead bridge crane provides with advanced PLC automatic detection function.
Overload Protection.
Standard Dual speed for hoisting with SWL below 32 Ton (VFD hoisting speed for SWL above 32 Ton)and variable frequency drive (VFD) control speed for cross and long travelling.
1. Smooth start and stop brings minimum impact and lower wear of brake, gears etc.
2. Variable controlled speed reduce load swing.
3. Slow speed for full load ensure safety while fast speed for light load improve efficiency.
4. Energy saving.
5. Low noise.
Electric Components. Electrical components uses ABB, Siemens and Schneider international brands.
Anti-collision Protection
For several cranes travelling on the same rail, the common resolutions refer to install contact anti-collision device to avoid sharp impact due to incorrect operation.
Tandem Operation
Loads can be safely transported by two ND(S) rope hoists through one single control unit, two cranes systems with up to four rope hoists can be synchronized as well.
Smart Electronic Anti-sway Control Technology
The electronic anti-sway control technology can reduce the mechanical and electrical damage caused by load shaking through controlling the sloshing of the load.
The double girder overhead bridge crane operator will concentrate on the load itself, rather than the movement of the crane, the entire transportation process will be safer, accurate and the work efficiency will be greatly improved.
