Advantages of Rail-Mounted Container Gantry Cranes (RMG)

Ideal for

• Port container yards

• Rail freight hubs

• Cross-border logistics parks

Background
As container traffic grows, RMGs help yards work faster and save space. They stack densely (e.g., "stack 4, reach 5" layouts), use electricity (less pollution), and can be automated. Downsides: limited to tracks, high upfront cost, and need steady power.

Technical Notes

• Typical RMG: 23m span, 40t capacity, 30m/min lift speed.

• Powered by ground cables, with 16 steel wheels.

• Digital PLC control with AC frequency drives.

• Can move and lift at the same time.

• Includes CMS/RCMS remote monitoring.

Rail-Mounted Gantry Cranes (RMG) are efficient electric cranes for container yards. Here are their main benefits:

✔ Eco-Friendly & Saves Energy – Uses electricity instead of diesel, cutting emissions and costs.
✔ Strong Lifting Power – Handles 20' and 40' containers (can lift two at once with twin-lift spreader).
✔ Fast & Smooth Movement – Moves quickly even with heavy loads, boosting yard efficiency.
✔ Precise Control – AC frequency control ensures steady lifting and reduces sway.
✔ Long-Lasting & Easy Maintenance – Heavy-duty steel and wear-resistant wheels for durability.

Key Features of Our RMG Cranes

1. Smart Control & Automation

• Uses Siemens PLC and Schneider frequency control for accuracy.

• Remote Monitoring (RCMS) allows real-time checks and control.

• Flexible Lifting Options

• Single or double drum systems for different loads.

• High-precision spreaders fit 20’/40’ or twin-lift containers.

• Strong & Safe Design

• Circular trolley system for better weight balance.

• Reduces sway for safer handling.

• Perfect for Ports & Terminals

• Moves on rails for wide yard coverage.

• Faster than rubber-tired gantries (RTG).
