Core Technical Advantages
- Four-beam, four-rail reinforced structure with stable load-bearing and exceptional torsional resistance: Features a four-beam, four-rail dual-trolley layout. The main beams utilize Q690 high-strength low-alloy structural steel, optimized through finite element analysis. Simulated under 360t full load, off-center load, and high-temperature radiation conditions, it ensures uniform load distribution. Structural rigidity exceeds LQ/1700 standard requirements, with torsional resistance improved by 50% compared to traditional double-beam structures. The trolley employs a balanced 24-wheel arrangement, distributing wheel pressure evenly to significantly reduce structural load on the plant building and minimize retrofitting costs.
- Comprehensive Safety Redundancy, Fortifying Molten Metal Handling Defenses: The main hoisting mechanism features an ultimate redundant design with dual motors, dual reducers, and quadruple braking. Should a single motor or reducer fail, the other set can independently complete one full work cycle, ensuring safe molten metal placement. Wire ropes utilize GB/T 8918 standard wire rope core-specific models with a safety factor of 9:1 (far exceeding the industry standard of 5:1), maintaining safe load-bearing capacity even if two diagonal wires break. Multiple safeguards include 90% overload warning, forced power shutdown at 1.05 times rated load, infrared temperature monitoring, and collision avoidance alerts. The hoisting mechanism incorporates an upper limit switch on the power circuit to prevent molten metal splatter caused by hook collisions with the machine body.
- Smart Manufacturing Processes Enhance Overall Reliability: Main beam welding employs intelligent robotic dual-wire submerged arc welding. Internal welds utilize MAG welding with mixed Ar+CO₂ shielding gas. All welds undergo 100% radiographic and ultrasonic testing with 100% pass rate. Large structural components like drums and trolley frames undergo natural gas annealing to fully eliminate welding stresses. Wheels and axles receive high-efficiency quenching and tempering treatment, achieving HRC 38-42 hardness and 30% improved wear resistance. The machine’s mean time between failures significantly exceeds industry benchmarks.
- High-Temperature Precision Protection for Extreme Environments: To withstand foundry workshop temperatures exceeding 1000°C, the lower section of the main beam incorporates dual ceramic fiber insulation. An intelligent cooling fan system within the main beam maintains the electronic control equipment’s operating temperature ≤40°C.
- The electrical system employs IP55-rated, H-class insulated YZR series metallurgical motors with ≥125°C temperature resistance. Combined with sealed dustproof cooling modules, it effectively withstands high temperatures and dust corrosion. The fully enclosed, insulated operator cab features industrial-grade air conditioning and radiation-resistant tempered glass, ensuring a comfortable and safe working environment.
- Modular Customization + Intelligent Synergy for Diverse Applications: Core parameters are customizable to meet specific requirements. The gantry hook supports both rotating and non-rotating configurations, precisely adapting to layouts of heavy casting workshops of varying scales.
- Featuring modular, equal-strength, equal-lifespan design, transmission and structural components offer high interchangeability for simplified maintenance. Supports fully automated operation with remote monitoring and fault diagnosis systems, seamlessly integrating with enterprise MES production execution systems. Enables automatic task reception and real-time operational data upload, boosting efficiency by over 35% compared to traditional equipment.
