Rubber tired gantry crane applies to international standard container transporting, loading and unloading at the container yard and railway container depots, with stable performance, high efficiency and ease maintenance having proper safety instructions and overload protection devices to maximizely ensure the safety of operational personnel and equipment. Electrical system uses PLC frequency adjustment which can easily control every mechanism. We are the professional rubber tired gantry crane manufacturer.

1,The power source is three-phase alternating current,rated frequency is 50HZ,rated voltage is 380V.
2,The working environment temperature ranges from -20℃ to +45℃ and the relative humidity is no lower than 95%(with dew).
3,In-service, the wind speed should be no higher than 20m/s; out-of-service, the wind speed should be no higher than 44m/s.
4,The working 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%.
6,The crane which has the special requirement for working conditions, can be manufactured following the contracts.

Steel shot blasting pretreatment, the surface quality reaches Sa 2.5 grade.
Crane wheel and wheel shaft through the high frequency quenching and tempering treatment, it eliminates the internal stress and ensures the machining accuracy. the use of welding robot, the main girder inseam weld by advanced MAG welding. The main girder welding adopts radiographic testing and ultrasonic testing to ensure the welding quality.
