FEM Standard Double Girder Gantry Crane – Powerful, Reliable & Engineered for Excellence

The FEM Standard double girder gantry crane is a high-performance lifting solution designed and manufactured in full compliance with European FEM standards. It is widely used in steel structure fabrication, machining workshops, metallurgy, shipbuilding, large-scale assembly, wind power equipment manufacturing, and port yards where heavy-duty and continuous operations are required.

Compared with traditional gantry cranes, the FEM Standard double girder gantry crane offers higher structural strength, longer fatigue life, and more precise motion control. It significantly improves operational efficiency and safety, making it the preferred double-girder gantry crane solution for modern factories and large manufacturing industries.

Advantages of FEM Standard Double Girder Gantry Crane

Engineered for high-frequency, heavy-duty, and continuous industrial applications, the FEM Standard double girder gantry crane delivers performance far beyond traditional gantry cranes. Through higher structural strength, lightweight girder design, and precision European-style drive systems, it delivers superior efficiency, safety, service life, and maintenance performance.

1. Lighter, Stronger, and More Efficient FEM-Designed Main Girder

Designed according to FEM high-strength and high-fatigue-resistance requirements, the girder adopts an optimized stress path and lightweight box-girder structure, reducing weight by 15–30% while providing higher rigidity, smoother operation, and lower energy consumption.

2. High-Precision European Hoisting and Travel Mechanisms

Built to FEM 9.511 requirements, the crane adopts compact European-style hoisting systems, frequency conversion control, integrated three-in-one drive motors, and high-precision gearboxes. This ensures smoother lifting and trolley/crab travel, reduced impact, and more accurate positioning.

3. Enhanced Safety Level in Compliance with FEM Standards

The hoisting mechanism, electrical control, and working class follow FEM 9.661 specifications to achieve a higher safety margin. Features include dual hoisting brakes (optional), anti-sway control, precise PLC-based positioning, and redundant protection for critical components, ensuring long-term stable operation under high-frequency workloads.

4. Longer Service Life with Higher Fatigue Resistance

The higher fatigue class required by FEM significantly improves the durability of girders, wheel groups, and drive components, making it ideal for multi-shift and 24/7 industrial environments.

5. Extended Maintenance Intervals and Lower Operating Costs

FEM-oriented optimization of wear points, inspection intervals, and component life reduces failures and maintenance frequency. This results in significantly lower lifecycle operating costs compared with conventional gantry cranes.

6. Precision Control for Smoother and More Reliable Operation

With high FEM control accuracy requirements, both trolley and crane travel use full frequency conversion control. This enables micro-speed operation, soft braking, reduced structural impact, and improved handling efficiency.

High-Performance European Design for a Lighter, Stronger Core Structure

The main girder is designed according to FEM requirements, using optimized force transmission and welded structures. The lightweight box-type double girder reduces weight by 15–30% while increasing strength and energy efficiency.

The hoisting mechanism features a compact layout with frequency control and a three-point support design, enabling clear force distribution and reducing overall crane height and self-weight.

The crane travel mechanism utilizes a three-in-one geared motor with a helical and bevel gear structure, offering high gear accuracy and low noise.

Wheel assemblies are manufactured from high-strength alloy steel, offering a high load capacity, long service life, and ease of installation and maintenance.
