Product Introduction of Henan Mine Crane’s Four-Girder Casting Bridge Crane

Henan Mine Crane’s four-girder casting bridge crane is a heavy-duty core equipment custom-designed for foundry workshops in steel and non-ferrous metal smelting industries. It precisely adapts to extreme operating conditions such as molten metal handling, ladle transfer, and casting lifting.

Featuring a four-beam, four-rail, dual-trolley structure at its core, the equipment integrates intelligent welding techniques, multi-level safety redundancy design, and enhanced high-temperature protection. This addresses industry pain points inherent in traditional double-beam casting cranes—poor load-bearing stability, weak torsional resistance, and high-temperature failure susceptibility—delivering a safe and reliable material handling solution for 24/7 continuous heavy-duty operations in foundries.

Core Technical Advantages

1. Four-beam, four-rail structure with stable load-bearing and high torsional resistance: Utilizing a four-beam, four-rail dual-trolley layout, the main beams are constructed from Q235B/Q345B high-strength steel. Optimized through finite element analysis, the structure exhibits superior stiffness under vertical and horizontal loads compared to LQ/1700, with strength ≤1000 kg/cm², far exceeding industry standard requirements. The trolley employs a balanced 20-wheel configuration with uniform wheel pressure distribution, effectively reducing structural steel costs for factory buildings.
2. Full-process safety redundancy ensures secure molten material handling:
   The main hoisting mechanism employs a redundant design with dual motors, dual reducers, and quadruple braking. If one motor fails, the other can temporarily operate to complete the current cycle. Multiple safeguards include overload warning, forced power shutdown at 1.05 times load capacity, infrared temperature monitoring, and anti-collision systems. An upper limit switch on the power circuit prevents hook collisions with the body, eliminating molten metal splatter.
3. Intelligent Manufacturing Processes Enhance Overall Reliability:
   The main girder welding employs industry-leading intelligent welding robots. Internal welds utilize MAG welding with a mixed shielding gas of Ar and CO₂, while external welds employ automatic submerged arc welding. All welds undergo radiographic testing and ultrasonic flaw detection to ensure welding quality, guaranteeing machining precision and service life.
4. High-Temperature Adaptive Design for Enhanced Operating Environment
   The lower section of the main beam incorporates dual thermal insulation systems. An internal cooling fan maintains optimal operating conditions for electrical control equipment. The operator cab features a fully enclosed, insulated structure with integrated cooling fans/air conditioning. The large-format tempered glass front panel provides expansive visibility while blocking high-temperature radiation. Electrical system utilizes IP55-rated, H-class insulation YZR series metallurgical motors, adapted for foundry workshops’ high-temperature, high-dust conditions to effectively prevent component failure.
5. Modular customization for diverse production needs
   Core parameters are customizable. Rated lifting capacities range from 125/32 to 320/80 tons, with spans ranging from 19 to 28.5 meters and lifting heights from 22 to 32 meters. The gantry hook supports both rotating and non-rotating configurations. Employing modular, equal-strength, equal-lifespan design, transmission and structural components are optimally matched for ease of maintenance. Customizable fully automated operation enables remote monitoring and fault diagnosis, supporting seamless integration with MES production systems. Operational efficiency improves by 32% compared to traditional equipment.
