Zomax RTG cranes are designed for space-efficient operations in container ports, terminals, and logistics, offering top container handling performance. They are equipped with the latest core lifting components (reducers, motors, controllers). The cranes are versatile and maneuverable, supported on pneumatic rubber tires making them less sensitive to ground unevenness.
A key feature of Zomax RTG cranes is that they can travel straight, sideways, 0-90 degree turns and rotate in place. They are available with diesel, hybrid, all-electric or battery power, and optional multi-function variable frequency anti-sway micro-motion system and electronic anti-sway system to enhance container stability and reduce sway during operations.
Zomax’s RTG (Rubber-Tired Gantry) Cranes for Logistics are engineered to provide versatile, energy-efficient, and highly accurate container handling across terminals, depots, and intermodal yards. Designed with durable rubber tires, advanced electronic systems, and multi-mode power options, our RTG cranes deliver exceptional traction, maneuverability, and control on various terrains.
RTG cranes operate on independent rubber tires, allowing them to move containers flexibly without the need for tracks. The crane's lifting system includes:
Open Winch Trolley for precise vertical hoisting via wire ropes and drums
Trolley Mechanism running on the main beam, supporting lateral movement
Main Car Mechanism equipped with 4–16 tubeless tires, enabling straight-line travel, sideway movement, 0–90° turns, and on-the-spot rotation
Electric Drive System using digital AC frequency conversion and PLC-controlled speed regulation for smooth, responsive operation
Optional diesel-electric hybrid or mains electricity + lithium battery systems allow energy-efficient use across diverse working environments
