Product classification
QY type insulated hook bridge crane
- Commodity name： QY type insulated hook bridge crane
- Description
-
This series of cranes includes various standard lifting capacities such as 5/5 tons, 8/8 tons, 10/10 tons, 20/20 tons, 32/32 tons, 40/40 tons, and 50/50 tons, with spans ranging from 7.5 to 40 meters. The lifting capacity is expressed in fractions, for example, 50/50 tons indicates a main trolley lifting capacity of 50 tons and an auxiliary trolley lifting capacity of 50 tons; the lifting height is also expressed in fractions, such as 14/14 meters, indicating a main trolley lifting height of 14 meters and an auxiliary trolley lifting height of 14 meters. The QY type insulated double girder bridge crane is a large crane with a capacity of 10T-50T. The QY type insulated double girder bridge crane is easy to install, of high quality, cost-effective, and flexible in operation. Its metal structure resembles a door frame, with two support legs installed under the main beam, allowing it to walk directly on the ground track, and the ends of the main beam can have extended cantilever beams.
The QY insulated bridge crane is suitable for smelting workshops of non-ferrous metals such as electrolytic aluminum, magnesium, lead, and zinc. Due to the presence of direct current equipment on the workshop floor, in order to prevent the current from the energized equipment during operation from being transmitted to the crane through the lifted components, endangering the driver's life and the safety of the equipment, several insulation devices are installed at appropriate locations on the crane. It is safe and reliable with good performance.
This crane operates under heavy-duty working conditions. To ensure safe lifting, the lifting mechanism is equipped with dual brakes.
All operations of this crane are completed in the driver's cabin.
Welding Process
1) The main steel structure (main beam, end beam) materials are all made of Q235-B, and the materials used have material reports and corresponding certificates.
2) The manufacturing, welding, and inspection of the steel structure are carried out according to industry standards. Important load-bearing butt welds adopt double-sided bevel welding technology, and external inspections and non-destructive testing are conducted as required, with all welders holding corresponding grade certificates.
3) All crane main beams use solid plate without butt joints, eliminating the hidden dangers of butt welds in steel plates.
4) All plates are automatically cut using CNC cutting machines, presetting the main beam camber to avoid the problem of traditional fire heating causing the main beam to sag.
5) The surface of the steel is treated with shot blasting, achieving a surface roughness that meets the Sa2.5 level in GB8923 "Steel Surface Treatment Registration and Rust Removal Level Before Coating", improving paint adhesion, preventing peeling, and ensuring the crane remains aesthetically pleasing for a long time.
6) The longitudinal welds of the main beam are welded using advanced automatic specialized machines, ensuring a beautiful shape and high welding quality.
7) The trolley crossbeam is made of rectangular tubes without splicing or welding, making it aesthetically pleasing, sturdy, and durable.
8) The wheel installation uses a boring hole method to avoid the wheel tread not being on the same horizontal plane, improving wheel running accuracy.
