Rubber tyred gantry crane is kind of special lifting device. It is mainly used for removing, loading, unloading and transporting international standard containers. It has advantages of high production efficiency, fine maneuverability, small sensibility to unevenness of the ground. RTG has two models trolley as tractor trolley and standard trolley. RTG is powered by cable drum. Diesel generating set is equipped for conditions when the power is off or the crane moves to another yard.
Port rubber tyred gantry crane has compact structure. It is mainly composed of the steel structure, lifting mechanism, micro-transfer mechanism, spreader anti-sway system, crane traveling mechanism, container spreader, electrical equipment and other necessary auxiliary equipment.

Application of rubber tyred gantry crane
Rubber wheel gantry crane is widely used in warehouse, container yard, port, material yard and workshop to assemble, load, unload cargo. It has operation ways as cabin control, remote control or pendent line with push button.
Standards modular design of rubber tyred crane
According to the general rules of products, RTG crane forms the following components, the hoisting mechanism module, trolley traction mechanism module, trolley assembly module, steel structure module, foundation module, general module and so on. The standards module production ensures product high quality and shortens the delivery cycle.
Advanced technology of RTG container crane
The crane is through steel shot blasting pre-treatment. The surface quality reaches Safety 2.5 grade. Crane wheel and wheel shaft are through the high frequency quenching and tempering treatment. It eliminated the internal and ensures the machining accuracy. The use of welding robot, the main girder inseam are welded by advanced MAG welding. The main girder welding adopts radio graphic testing and ultrasonic testing to ensure the welding quality.
The spreaders are based on forging technology with the high quality. The main beams and legs are one time forming without welding beam U frame, and carefully welding of the whole beams. The trolley is comprised of motors for lifting and traveling, brake, reducer, coiling block and electric power transmission device. The skills are professional and safe.
