Product Overview

Engineered for high-performance container handling in ports and rail terminals, this rail-mounted gantry crane (RMG) features a robust double-girder structure, vertical legs, and specialized end trucks for smooth rail movement. The top-running trolley is paired with a flexible spreader capable of securely lifting 20′, 40′, and 45′ containers.

Built to maximize operational efficiency, the RMG’s vertical leg design enables seamless container passage between the span and cantilever areas. A rotary-type cart ensures steady multidirectional loading and unloading, while an optional non-rotary cart with a rotating spreader provides added versatility for container positioning.

Designed for demanding, all-weather applications, this crane meets M6 to M8 (ISO) duty classifications and features variable frequency drives for precise speed control. It performs reliably across extreme temperatures, from -40°C to 40°C, making it ideal for harsh environments.

Compliant with GB standards and certified by ISO and CE, this RMG model guarantees safety, durability, and international compliance.

Application Scenario

Rail Mounted Gantry (RMG) cranes serve as critical infrastructure components within global supply chains, providing specialized container and heavy cargo handling solutions. These robust systems deliver maximum operational efficiency across multiple logistics environments.

Primary Operational Environments:

Container Terminals and Ports
Optimized for high-density stacking operations, our RMGs enable rapid loading and unloading of vessels at berth. Their precise electric or diesel-powered movement ensures smooth container transfers between ships, trucks, and storage areas, significantly improving vessel turnaround times.
Intermodal Rail Yards and Logistics Hubs
Facilitating seamless cargo transfer between transportation modes, these cranes efficiently manage container movement from railcars to truck transport. The vertical leg design allows unimpeded container flow, while specialized spreaders securely handle 20', 40', and 45' containers with exceptional stability.
Container Storage and Depot Management
Engineered for all-weather reliability (-40°C to 40°C), RMGs provide uninterrupted operation in outdoor storage facilities. Their M6-M8 duty classification supports continuous container stacking, reorganization, and retrieval operations, maintaining workflow efficiency even under demanding conditions.

Handling Capabilities and Operational Advantages:

Beyond standard container operations, our cranes accommodate various cargo types through customizable attachments. The rotary trolley system provides multidirectional loading capability, while optional configurations support specialized lifting requirements. With ISO and CE certified construction meeting GB standards, these RMGs deliver reliable performance for diverse freight handling needs while ensuring compliance with international operational safety regulations.

The integration of frequency inverter controls enables precise speed management during container positioning, minimizing handling time while maintaining maximum safety standards. This technical sophistication makes RMG systems indispensable for modern terminals seeking to optimize their cargo throughput and storage density.
