Large-tonnage double-girder cranes ensure stable assembly operations for large heavy industrial equipment.

Industrial scenarios such as large-scale heavy equipment manufacturing, large pressure vessel processing, wind power equipment assembly, and heavy steel structure assembly commonly involve production demands for hoisting large-tonnage workpieces, aligning entire equipment, and performing continuous heavy-load assembly. Conventional small-to-medium tonnage lifting equipment has limited load-bearing capacity and insufficient structural rigidity, failing to meet the operational standards for hoisting large components as a whole. Segmented hoisting easily leads to assembly errors, cumbersome procedures, and low work efficiency. Large-tonnage double-girder cranes are specifically designed for heavy equipment manufacturing conditions, offering ample load-bearing redundancy and strong structural stability. They can complete the overall hoisting and precise assembly of large workpieces, effectively simplifying production processes and improving assembly accuracy.

The equipment adopts a thickened, integrally welded box-type double main beam structure, exhibiting excellent overall bending, torsional, and compressive resistance. Under ultra-large tonnage heavy-load operation, the machine body shows no deformation or vibration. Its structure demonstrates outstanding fatigue resistance and impact resistance, making it suitable for long-term, high-intensity, uninterrupted heavy-load assembly operations in workshops. The entire machine undergoes stress-relief treatment, ensuring long-term structural stability. Long-term, high-frequency, heavy-load operation is less prone to structural loosening or deformation, significantly extending the equipment's service life. The equipment's walking and lifting drive system has ample power reserves, ensuring smooth start-up under heavy loads and stable, uniform operation, effectively preventing swaying and misalignment during the hoisting of large components.

The equipment is equipped with a comprehensive intelligent safety protection system, integrating real-time overload monitoring, dual high and low position limits, buffer collision protection, pressure loss protection, and emergency interlock shutdown, mitigating safety hazards in heavy-duty hoisting from the outset. The enclosed operator's cab offers excellent visibility and convenient operation. Upgrades are available as needed, including variable frequency stepless speed regulation, micro-motion positioning, and an intelligent anti-sway system, meeting the millimeter-level precision alignment and assembly requirements for large components. The equipment is suitable for routine overall hoisting, turning, assembly, and maintenance operations in various heavy industrial workshops, effectively enhancing the integrated operation capabilities of heavy equipment manufacturing, reducing process losses caused by segmented hoisting, and contributing to quality and efficiency improvements in the heavy manufacturing industry.
