FEM Single Girder Gantry Cranes: Lightweight, Safe & Reliable Lifting Solution for Multiple Industries

FEM Single Girder Gantry Crane integrates advanced European technology, with lightweight and modular design as its core. It adopts new configurations and manufacturing processes, complies with the latest national standards, and references international standards including FEM, DIN, and IEC. As an upgraded replacement for traditional hoisting equipment, it uses an electric hoist as the lifting mechanism, operates on ground rails supported by outriggers on both sides, and achieves three-dimensional material handling. Compared with traditional models, FEM Single Girder Gantry Crane features lower dead weight and reduced wheel pressure; its high-precision transmission components are paired with a speed control system, ensuring stable and accurate operation. It also boasts energy efficiency and low operation and maintenance costs, being widely applied in material transfer across machinery manufacturing, warehousing, assembly, chemical, railway and other industries.

Advantages of FEM Single Girder Gantry Cranes

Reliable Structural Welding: The bridge frame is measured with an optical calibration device and its cross-section is machined, ensuring the connection accuracy and parallelism of end beams for stable operation. CO2 gas shielded welding is adopted for steel welding, reducing weld oxidation and improving mechanical properties.
High-Strength Materials & Reduced Dead Weight: The lifting mechanism, steel structure and accessories adopt rational structures and high-strength materials, increasing load-bearing capacity while reducing self-weight by 15%~30%. It has lower dead weight, smaller wheel pressure and lower energy consumption than traditional cranes.
Low Operation & Maintenance Costs: The FEM Single Girder Gantry Crane is equipped with standardized high-quality, high-performance components, reducing daily maintenance workload and time. Its low overall power consumption ensures higher energy efficiency and lower operating costs.
High Working Performance: Full-machine frequency conversion technology enables speed adjustment according to load, with a wide speed regulation ratio of 1:10 and high speed controllability. Combined with anti-sway technology, it achieves high-precision positioning of lifted items.
Safe & Reliable with Multiple Protection Measures: It features an independent motor air cooling system for overheat protection; a high-quality steel drum to reduce wire rope wear; and advanced PLC functions to monitor crane performance, safety and operation status for timely fault detection.
Self-Developed & Manufactured Core Components: 90% of core components such as precision castings and high-end drive parts are self-manufactured, ensuring controllable quality and better adaptability. Core components (e.g., couplings, wheels) can be quickly replaced to minimize downtime

Premium Components for FEM Single Girder Gantry Crane

Electric Hoist: It adopts imported German hoisting motors and reducers, with a modular and compact layout to save space. It features light weight, small size, strong component versatility and easy operation, ensuring small lifting swing and precise positioning during operation. Additionally, it boasts high reliability, low maintenance costs and safe use.

Crane Main Ginder: It is made of special cold-drawn rail steel, with a rectangular beam cross-section. It features uniform force distribution, resistance to deformation, long durability, and an overall weight reduction of 15%~30%.

The end beam adopts a rectangular tube formed by standard automated one-time welding, with excellent mechanical properties and stable quality. Connected to the main beam via 10.9-grade high-strength bolts, it uses CNC boring for small machining errors, ensuring precise assembly with wheels.

The electrical control box features modular integrated design, high standardization, easy replacement/installation and IP55 protection. It has concise wiring, no noise during operation and stable performance, with key electrical components from Schneider.

The wheel assembly is manufactured from high-strength alloy steel. Compared with ordinary wheels made of carbon steel, it possesses significantly superior wear resistance, which can effectively prolong the overall service life of the wheel assembly.

Application Industries & Scenarios of FEM Single Girder Gantry Crane

• Machining Workshops: Hoists machine tool beds, large gears and shaft workpieces, facilitating component processing, transfer and equipment assembly.
• Outdoor Warehouses & Logistics Parks: Loads/unloads bundled steel, steel coils and large equipment packaging, enabling efficient cargo stacking and turnover.
• Railway Yard Transfer: Hoists 20ft containers, bundled rail tracks and heavy machinery parts, connecting cargo transfer between railway and other transport modes.
