Project Overview:

This engineering drawing was tailored by Yuantai Cranes for international large-scale container hub ports, railway container transfer stations, and high-intensity multimodal logistics centers, designated as model RMG50t-36m Rail Mounted Gantry Crane (RMG) (Drawing No.: RMG50-36 A7). The complete structural length reaches 52.0 meters, featuring a 36.0-meter main span and symmetrical 5.0-meter cantilevers on both sides, perfectly balancing high-density yard stacking and efficient external truck passage requirements.

Yuantai 50-Ton Heavy-Duty Rail Mounted Gantry (RMG) Crane Custom Configuration: Span 36.0m, lifting height 15.0m, featuring 5.0m cantilevers on both sides (total length 52.0m), with a rated lifting capacity of 50t (referring to the net capacity underneath the spreader excluding spreader weight). Specially engineered for high-throughput ports and freight yards, capable of handling 20-25 containers per hour, supporting 20ft, 40ft, and 45ft containers with 360° automatic rotation. The leg clearance area is specifically optimized for container trucks and trailers measuring 3 meters wide, 15-18 meters long, and 5 meters high. Equipped with a luxury operator cabin traveling with the trolley, full frequency conversion electrical system, hoisting speed of 4.0~20 m/min (with load) to 7.5~37.5 m/min (without load), trolley and gantry travel speed of 6.5~38.8 m/min, and a travel length of 340m. Fitted with R65 heavy-duty rails, designed to withstand severe outdoor environments ranging from -40℃ to 50℃ combining extreme cold and heat.

Yuantai Crane 50t Rail Mounted Gantry Crane Drawing and Technical Specification (Model: RMG50t-36m A7, Drawing No.: RMG50-36 A7, Span: 36.0m, Dual Cantilevers: 5.0m each, Lifting Height: 15.0m, ISO A7/M7 Duty Class, Total Weight: 268t)

The core competitive advantage of this project lies in its super-heavy duty (ISO A7/M7) reliability and exceptional handling efficiency: the rated lifting capacity reaches 50 tons (net capacity underneath the spreader excluding spreader weight), equipped with a high-performance spreader capable of handling 20ft, 40ft, and 45ft containers with 360° automatic rotation, achieving a single-machine handling efficiency of 20-25 containers per hour. The gantry leg clearance perfectly accommodates large container trucks/trailers with a length of 15-18m, width of 3m, and height of 5m; the entire machine adopts full frequency conversion drive with a gantry travel length of 340 meters, perfectly adapted to extreme outdoor climates from -40℃ to +50℃.

Technical Requirements & Manufacturing Standards

Important Engineering Standard Notes:

1. Design & Manufacturing Codes: The design, manufacturing, installation, inspection, and acceptance of this crane shall strictly comply with the GB/T19683 national standard.
2. Insulation Resistance Testing: When measuring the insulation resistance to ground and phase-to-phase resistance, the entire power circuit and control circuit of the crane must be connected across all lines, with a value of not less than 0.5M$\Omega$ (insulation resistance can be reduced by 50% in humid areas).
3. Grounding Protection: The shells of all electrical equipment on the crane must be reliably grounded; crane tracks are permitted to be used for grounding, and the metal structure of the plant serves as a grounding conductor.
4. Environmental Temperature Range: Specifically engineered for extreme outdoor heavy-duty environments with an ambient temperature range of -40℃ to +50℃.
