50 Ton Lifting Equipment Rail Mounted Gantry Crane for Sale
Overview
The Rail Mounted Gantry (RMG) Crane is a highly efficient container handling solution widely used in ports, docks, and inland container yards. It is designed for stacking, loading, unloading, and transferring international standard containers between ships, trucks, and storage areas.
The crane’s main beam adopts a strong box-type structure, supported by robust outriggers on both sides that allow smooth movement along ground rails. This design ensures superior stability and strength during heavy-duty operations. Driven by an advanced full-digital AC frequency conversion system and PLC speed regulation control, the RMG crane delivers precise, flexible, and energy-efficient performance. All key components are sourced from internationally recognized brands to ensure long-term reliability.
With its multi-functional design, high stability, and easy maintenance, the RMG crane offers outstanding efficiency and dependable performance in modern container terminals.
Main Components
Main Beam: The main beam adopts either a box-type or truss structure, serving as the primary load-bearing element that supports both the hoisting mechanism and the trolley system. It ensures rigidity and stability while maintaining high structural strength under heavy loads.
Outriggers: These rigid steel frames connect the main beam to the traveling carts. They efficiently transfer the crane’s weight and the lifted load to the ground rails, guaranteeing overall machine stability and balance during operation.
Traveling Cart: Equipped with a motor, reducer, and wheel sets, the traveling cart enables the crane to move smoothly and accurately along the rails, ensuring efficient container positioning across the yard.
Hoisting Mechanism: Comprising a motor, drum, wire rope, and spreader, this system performs vertical lifting and lowering of containers. Advanced speed control and anti-sway functions provide smooth and safe lifting operations.
Trolley Running Mechanism: This mechanism drives the spreader horizontally along the main beam, utilizing frequency-conversion control for precise alignment and efficient handling.
Electrical Control System: Integrated with PLC and inverter technology, it coordinates crane movements, supports semi-automatic operation, and monitors faults in real time.
Safety Devices: Equipped with overload limiters, travel limit switches, and windproof anchors, ensuring safe and reliable crane operation under all conditions.
Advantages
Exceptional Anti-Sway Performance: Advanced control technology minimizes load swing during lifting and traveling, ensuring safer and faster container handling even in challenging conditions.
Precise Spreader Positioning: Without a headblock structure, the operator benefits from improved visibility and accurate spreader alignment, enabling faster and more reliable container placement.
Lightweight and Efficient Design: The absence of a headblock reduces the crane’s tare weight, lowering structural stress and improving energy efficiency during operation.
Enhanced Productivity: Compared to traditional crane designs, RMG cranes offer higher handling speeds, shorter cycle times, and greater overall throughput in container yards.
Low Maintenance Costs: Simple mechanical design and durable components reduce maintenance frequency, minimizing downtime and spare part expenses.
Stable Gantry Movement: Smooth traveling and precise control ensure steady operation, even under heavy loads or uneven rail conditions.
High Wind Resistance: Engineered for stability, the crane maintains superior performance and safety in high-wind environments commonly found in coastal ports.
Automation-Ready Design: The RMG crane structure and control systems are optimized for full or semi-automated operation, supporting smart port development and long-term efficiency.
Energy-Efficient and Reliable Support: With lower power consumption and strong technical aftersales service, RMG cranes deliver dependable, cost-effective performance throughout their lifespan.
