Advantages of Gantry Cranes in Construction Projects with their unique portal frame structure and flexible performance, emerge as the core solution to these construction pain points. As a leading domestic crane manufacturer, Henan Mine Crane leverages over 30 years of technical expertise to deliver construction-specific gantry cranes. These cranes stand out for their wide coverage, high load capacity, and precision, making them the top choice for countless construction enterprises.

Construction sites often involve coordinated operations across multiple zones—material storage areas, component assembly zones, and work surfaces. Traditional tower cranes rely on tower rotation, creating circular blind spots, while tire-mounted cranes have limited mobility, making frequent relocation time-consuming and labor-intensive. Henan Mine Crane eliminates coverage challenges through its three-dimensional coordinated design: “gantry + main trolley + auxiliary trolley.”

Henan Mine Crane offers customizable spans (3-50 meters) to span entire construction zones. The main girder travels longitudinally along rails while the trolley moves transversely, creating a rectangular, dead-angle-free operational envelope. A single installation covers the entire workflow from material transfer to component installation. For instance, at a prefabricated residential project in Zhengzhou, a 20-ton Henan Mine Crane covered a 1,200-square-meter construction area. Eliminating frequent equipment relocation boosted material transfer efficiency by 40% compared to traditional tower cranes.

Additionally, Henan Mine Crane offers lifting heights ranging from 1 to 30 meters. This capability spans all construction phases—from hoisting rebar cages during foundation work, to installing prefabricated wall panels in the main structure, to erecting roof steel frameworks—without requiring equipment changes, significantly reducing process transition times.

II. Rock-Solid Heavy-Load Lifting, Meeting Demands for Heavy Building Components

With the advancement of industrialized construction, the demand for lifting heavy components—such as precast composite slabs, steel columns, and steel beams (often weighing 10-50 tons each)—is growing, placing stringent demands on equipment load capacity and stability. Henan Mine Crane, with its high-strength structures and optimized designs, emerges as the “reliable partner” for heavy-duty lifting. The base of the outriggers features a widened load-bearing beam design, increasing ground contact area by 30%. Combined with a rail-based foundation, lateral displacement during the lifting of a 50-ton steel component is only 2mm, offering stability far exceeding that of tire-mounted cranes. For sites with soft ground foundations, Henan Mine also offers a customizable “pile + steel plate” composite foundation solution to distribute ground pressure and prevent equipment overturn risks.

In a steel structure plant project, Henan Mine Crane's 40-ton gantry crane lifted a 32-meter-long steel truss. The entire process—lifting, traversing, and positioning—remained exceptionally smooth. Single-truss installation time was reduced from 1.5 hours with traditional equipment to just 40 minutes, significantly boosting construction efficiency.

III. Precise Control and Easy Operation Meet Demanding Construction Requirements

The equipment features a PLC variable-frequency control system, enabling independent speed regulation for the three major mechanisms: hoisting, main travel, and trolley travel. Hoisting speed can be reduced to a minimum of 0.5m/min, while traverse speed can be precisely controlled at 0.1m/s. Equipped with high-definition cameras and display screens, operators can monitor component alignment in real time. Combined with wireless remote control devices, this enables “long-distance precision operation.” At a bridge precast yard in Xi'an, Henan Mine Crane lifted a 20-ton precast T-beam with alignment errors controlled within 3mm—significantly exceeding the industry standard of 8mm.

Additionally, the Henan Mine Crane features an anti-sway function. Sensors continuously monitor component oscillation angles, automatically adjusting travel speed to prevent swaying during high winds or rapid movements, thereby reducing risks in elevated operations.

IV. Exceptional Site Adaptability for Complex Construction Environments

Rail-mounted: Ideal for long-term fixed operations (e.g., prefabricated building factories, large-scale plant construction). Simple track installation ensures stable operation and enables 24/7 continuous work.

Tire-mounted: Requires no track installation. Equipped with wide-base tires, it demands low ground bearing capacity and suits temporary operations or sites with variable conditions (e.g., municipal projects, small bridge construction).

Crawler-mounted: Features minimal ground pressure (only 0.08MPa), enabling operation on muddy or soft terrain. Ideal for complex construction environments like excavation perimeter areas and mountainous terrain.

At a Wuhan foundation pit project, Henan Mine Crane operated along the pit edge, lifting 15-ton rebar cages without entering the pit. This prevented pressure damage to the pit support structure, ensuring construction safety.

V. Low Consumption & Durability + Full-Cycle Service Reduce Construction Costs

Core components (motors, reducers, brakes) utilize top domestic brands, undergo 100,000 fatigue tests, and achieve a failure rate 35% lower than industry averages. Gantry surfaces feature sandblasting rust removal + fluorocarbon coating for superior corrosion resistance, ensuring over 20 years of service life in harsh environments like high rainfall and extreme heat. For routine maintenance, critical components are centrally located, enabling lubrication and inspections without elevated work platforms. This reduces maintenance costs by 40% compared to tower cranes. A construction group using Henan Mine Crane for five years reported average annual downtime for maintenance under 20 hours, with no construction delays caused by equipment failures.

From bulk component hoisting in prefabricated modular construction to heavy steel installation in industrial plants, and precast girder erection in bridge projects, Henan Mine Crane deliver “wide coverage, high load capacity, precision engineering, flexible adaptation, and cost-effectiveness.” They have served over 100,000 construction projects across 122 countries worldwide.
