Rubber Tyre Mobile Harbour Port Container Gantry Cranes(RTG) are special equipments to remove, load and unload containers in port. The port crane can run and move in the yard, it has the great feature of high working efficiency and fine maneuverability, also be influenced by unevenness of the ground. RTG is powered by cable drum. At the same time, the most outstanding advantage is that it with diesel generating set for the situation when the power is off or the crane need to move to another yard.
1,The common power source is three-phase alternating current, rated frequency is 50HZ/60HZ ,rated voltage is 380V. (Special request power is customized)
2,The working environment temperature ranges from -20℃ to +55℃ and the relative humidity is no lower than 95%(with dew).
3,In-service, the wind speed should be no more than 20m/s; out-of-service, the wind speed should be no more than 44m/s.
4,The work duty is A6-A7.
5,The gradient of crane traveling floor should be less than 1% and part of that should be no more than 3%.
According to the general rules of products, components, the Heavy Duty Port Marine Crane STS forms the lifting mechanism module, trolley mechanism module, trolley assembly module, steel structure module, function module, general module and so on. Due to the standard module production can make products with stability quality and shortens the delivery period.
