High Strength Bridge Crane

Bridge Crane, also known as overhead crane, is a modular lifting equipment installed above the span of buildings such as factory workshops, stockyards and warehouses, operating longitudinally along fixed rails. Adopting a bridge-type steel structure main body spanning the operation area, it cooperates with the lifting trolley moving transversely along the main beam to realize the lifting, handling, shifting and stacking of materials in a three-dimensional space. As the most widely used general lifting equipment in industrial production, the product strictly complies with national GB/T, ISO and FEM international crane machinery standards. With mature structure, stable operation and strong load capacity, it can adapt to light, medium and heavy working conditions. Divided into two mainstream types: single-girder bridge crane and double-girder bridge crane, it is widely used in machinery manufacturing, metallurgy, warehousing, mines, ports, infrastructure and other industrial scenarios, serving as the core equipment for modern factories to realize mechanized handling and improve production efficiency.
The core load-bearing components such as main beams and end beams of the product are made of national standard Q235B and Q355B high-strength structural steel, featuring high overall section stiffness, excellent bending resistance and sufficient structural toughness, which effectively avoids deformation, shaking and fatigue damage under long-term heavy-load operation. The whole machine is integrally welded and formed, with key welds inspected by non-destructive testing to ensure uniform and full welding and balanced stress, meeting the standards for overall structural strength and stability. The walking rails and wheel sets are forged from alloy steel and quenched for hardening, with excellent wear and pressure resistance and long service life, suitable for high-frequency reciprocating operation. The electric control system adopts well-known brand electrical components, equipped with brake motors, reducers, limit devices and other core accessories, ensuring accurate operation, sensitive braking and low failure rate. All steel structure surfaces are treated with multi-layer anti-corrosion processes including derusting, anti-rust primer and finish paint, featuring wear resistance, corrosion resistance and aging resistance, adapting to conventional indoor working conditions and complex outdoor environments with dust and humidity.
