40 Ton Rubber Tyred Gantry Crane for Container Logistics Terminal

A Rubber Tyred Gantry Crane (RTG crane) is a heavy-duty, self-propelled lifting solution widely used in ports, container terminals, freight yards, and intermodal logistics centers. Its primary function is to handle, transport, and stack standard shipping containers such as 20-foot and 40-foot units with high efficiency. Unlike rail-mounted gantry cranes, an RTG crane operates on large rubber tires rather than fixed tracks, allowing it to move freely across paved surfaces. This trackless design enables forward, backward, and lateral movement, providing exceptional flexibility and fast repositioning within busy yard environments.

Structurally, the RTG crane features a tall gantry frame supported by multiple vertical legs, which creates a wide working span beneath the crane. At the top, a robust bridge beam supports a trolley system that travels horizontally along the span. This trolley carries the main lifting device—the container spreader—which is designed to automatically lock onto the corner castings of containers. With precise vertical and horizontal control, the RTG crane can lift containers smoothly, transport them across the yard, and place them accurately into storage stacks or onto trucks and trailers.

Thanks to its mobility, stability, and precise handling capability, the RTG crane plays a vital role in improving container throughput, optimizing yard space, and supporting modern port and logistics operations.

♦Overload Protection System: The rubber tyred gantry crane is equipped with a reliable overload protection device. When the lifted load exceeds the rated capacity, the system immediately triggers an audible and visual alarm and automatically restricts further lifting. This prevents structural damage and ensures the crane always operates within safe working limits.

♦Emergency Braking System: An emergency brake function is built into the crane for unexpected situations. In the event of sudden danger or operational failure, the operator can activate the emergency brake to stop all movements instantly, protecting both personnel and valuable cargo.

♦Safe Control Methods: Multiple control options are available, including ground control and cabin control. These flexible control methods allow operators to maintain a safe distance from the load when necessary, significantly reducing the risk of personal injury during lifting operations.

♦Protected Lifting Motor: The main hoisting motor features thermal protection and overcurrent protection. These safeguards prevent overheating and electrical overload, extending motor service life and maintaining stable lifting performance.

♦Secure Lifting Hook Design: High-strength hooks are fitted with safety latches to prevent the load from slipping or detaching during lifting, lowering, or traveling operations.

♦High-Quality Buffers: Durable polyurethane buffers with long service life are installed to absorb impact energy, minimizing collision forces and protecting crane structures.

♦Protective Earthing System: A complete grounding system is applied to prevent electrical shock and ensure safe operation under all working conditions.

♦Travel Limit Switches: The rubber tyred gantry crane traveling limit switches effectively prevent over-travel, ensuring smooth, controlled, and secure movement across the working area.
