Port Cranes
RTG Rubber Tyre Container Gantry Cranes are indispensable in handing, loading, and unloading ISO container in container yards or transfer station such as port, wharf and logistics. Supported by pneumatic rubber tires and powered by diesel generators, cable drums or lithium batteries, these cranes consist of gantry mechanism, trolley assembly, gantry frame, power system and special container spreader. All parts work together to ensure the efficient operation of the crane. The gantry mechanism and frame provide a stable structural foundation for the whole equipment. The trolley assembly is responsible for the horizontal movement of containers within the gantry, and the special spreader can accurately grab and lift containers. Their design, manufacture, and inspection adhere to both Chinese and international standards like FEM, DIN, IEC, and AWS, guaranteeing high quality and wide applicability in the global market.
Weihua's RTG cranes are multifunctional and highly efficient, reducing container - handling time and enhancing overall operational efficiency in ports or logistics hubs, stable under heavy loads and reliable during long - term operation to minimize breakdown risks. They have an extensive operation range and remarkable maneuverability, being able to travel straight, laterally, make 0 - 90 degree turns and turn in - place with ease to adapt to different container storage layouts and complex working environments and are less affected by ground unevenness. Their operation is user - friendly with a simple interface for quick operator proficiency and maintenance is easy with accessible components and a clear procedure, reducing downtime and costs.
Safety is prioritized with a comprehensive safety indication system giving clear warnings and an effective overload protection device responding promptly to overloads to safeguard the equipment and operators. The electric drive system uses full digital AC variable frequency and PLC speed control technology for flexible and accurate control, allowing smooth speed adjustments during start - up, stop and speed - changing with minimal mechanical shock and wear and precise control of gantry, trolley and spreader movements for accurate container - handling, and we use standard - bought - in components from renowned domestic and international brands that are rigorously tested for excellent performance and durability to ensure long - term stable operation and reliability.
