Henan Mine Heavy-Duty Engineering Double-Girder Gantry Crane Product Introduction

Henan Mine’s 750-ton double-girder gantry crane is a “giant-class” premium equipment developed by the company to meet the material handling demands of super-large engineering projects.

The equipment addresses core pain points in heavy-duty lifting—safety redundancy, precision efficiency, and energy-saving economics—by integrating intelligent control, high-strength structural design, and green energy-saving technology. It comprehensively resolves industry challenges in lifting oversized components, such as excessive wheel pressure, difficult balance control, and high energy consumption. This crane provides a one-stop heavy-duty lifting solution for scenarios including heavy equipment manufacturing, large-scale infrastructure projects, and port terminal heavy-load operations.

As a flagship product embodying Henan Mine Machinery’s “from strength to precision” transformation, this crane leverages the company’s intelligent and green manufacturing system. It features an innovative single-side dual-track design and PLC + inverter communication control technology, paired with a multi-point synchronous balancing system and full-vehicle safety monitoring system. This ensures stable lifting of 750-ton super-heavy loads while achieving 25%-30% energy savings. Constructed from high-strength special steel, the product enables continuous operation under equivalent loads, fully adapting to the high-intensity, demanding conditions of super-large projects. This demonstrates Henan Mine Machinery’s R&D and manufacturing prowess in heavy-duty lifting equipment.

Core Technical Advantages

Heavy-Load Safety Redundancy: Stable and Reliable: Equipped with a whole-vehicle safety monitoring system that continuously tracks critical parameters like lifting capacity, operational status, and balance precision. It automatically alerts and triggers protective measures during anomalies. Utilizes PLC + inverter communication control paired with multi-hoist point synchronization technology to automatically adjust lifting balance, eliminating heavy-load imbalance risks and achieving operational stability far exceeding industry standards. The hoisting mechanism features a dual-braking design, with critical structures optimized through finite element analysis, fully meeting the safety requirements for lifting 750-ton super-heavy loads.

1. Innovative Structural Design for Specialized Conditions: Innovatively employs a single-side dual-track design tailored for project-specific conditions. This effectively reduces crane wheel pressure, minimizes site foundation requirements, indirectly saves infrastructure costs, and enables lightweight equipment design. It also supports continuous operation under equivalent loads, significantly boosting heavy-duty work efficiency.
2. Intelligent Precision Positioning, Doubling Operational Efficiency: Equipped with a high-precision automatic positioning system achieving ±5mm accuracy, it rapidly and accurately aligns with lifting positions, reducing manual adjustment time. PLC + VFD closed-loop control enables stepless adjustment of lifting and travel speeds, ensuring smooth, shock-free starts and stops. This protects lifted components from damage while further enhancing operational continuity and overall efficiency.

Green Energy Upgrade, Reduced Total Cost of Ownership: The entire vehicle operates on a 10KV high-voltage power supply mode. During heavy-load descent, electrical energy is automatically recovered and fed back into the grid, achieving energy savings of 25%-30%. Based on an annual operation of 8,000 hours, this translates to annual electricity savings of hundreds of thousands of kilowatt-hours. The use of high-strength steel not only extends equipment lifespan but also reduces maintenance frequency, lowering customers’ total operating costs through both energy consumption and maintenance savings.
