Product Feature And Application

Tangshan Yuexin Machinery Manufacturing Co., Ltd.'s Bridge Erection Machine Components utilize a combination of CNC gantry machining centers and large submerged arc welding machines. After welding, the structural components undergo vibration aging treatment, effectively eliminating internal stress and preventing deformation under heavy loads. Key load-bearing components (outriggers and lifting beams) are made of Q460C high-strength steel, with a tensile strength ≥460MPa and impact resistance ≥47J (-20℃), fully meeting the demands of extreme working conditions. Connections are precision-machined, with bolt hole positioning accuracy ≤0.03mm, ensuring seamless integration with the bridge erecting machine and convenient installation. Custom sizes are also supported, accurately replicating customer drawings to suit bridge construction needs of different spans and tonnages.

Our accessories have a wide range of applications. The outrigger assembly is responsible for the vertical load-bearing and lateral leveling of the bridge erecting machine, ensuring stable support during bridge erection. The main beam and crossbeams form the core load-bearing frame, supporting the hoisting and transport of bridge beams. The lifting beam device and guide wheel assembly enable precise lifting, translation, and alignment of the beams, improving construction efficiency. These accessories are widely used in large-scale bridge projects such as highways, high-speed railways, and cross-sea bridges, adaptable to the erection of various beam types, including simply supported beams and continuous beams, and are the core guarantee for the safe and efficient operation of the bridge erecting machine.

Tangshan Yuexin Machinery's Bridge Erection Machine Components adheres to a strict, standardized process control system encompassing "drawing analysis - raw material selection - precision machining - heat treatment - comprehensive testing," ensuring product quality through stringent standards. In the raw material stage, high-strength steel undergoes ultrasonic testing, spectral analysis, and mechanical property testing to eliminate defects such as cracks and slag inclusions, ensuring that material composition and strength meet standards. In the machining stage, CNC equipment precisely processes key structures and connecting holes. Large structural components are processed in sections combined with overall assembly and calibration to maintain precise dimensional accuracy.

The welding process is carried out by certified welders using submerged arc welding and gas shielded welding techniques. The welds are inspected by X-ray flaw detection to ensure that the welding quality meets the Class II standard. In the post-treatment process, the oxide scale is removed by shot blasting, followed by the application of multiple layers of anti-corrosion coating, and finally vibration aging to eliminate welding internal stress. In the testing process, a tensile testing machine, hardness tester, and coordinate measuring machine are used to conduct a full range of tests, and a complete test report is issued to ensure that each component meets the bridge construction safety standards.
