Product Description
The rubber-tired gantry crane can realize a variety of modes such as straight travel, diagonal travel, horizontal travel, in-situ rotation, Ackerman steering, etc.Crane traveling mechanism adopt to structure of wheel and can achieve 360ºC turn and run diagonally.
It has mobility, flexibility, adaptability, high work efficiency, small size occupation area and do not need to lay the rail which are particularly suitable for beam factories and port with horizontal layout.
The crane mainly consists of main beam, support leg, hoisting mechanism, tire walking and braking system, steering mechanism, power system, electrical system, hydraulic system, hydraulic transmission system, cab, control system, safety device, etc.
Environmental Conditions:
1.The power source is three-phase alternating current,rated frequency is 50HZ,rated voltage is 380V.
2.The working environment temperature ranges from -20ºC to +45ºC 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.
Rtg Rubber Tyred Container Gantry Crane for Port
RTG Double Girder Gantry Crane usually called RTG for short, which is employed to stack containers in container storage yards construction to do common lifting and unloading works.It is flexibly moved by its own rubber tires for transshipping containers. RTG Double girder gantry crane is composed of bridge, support legs, crane travelling organ, trolley, electric equipment,strong lifting winch. The frame adopts box-type welding mechanism. Crane travellilng mechanism adopts separate driver. All mechanisms are operated in the driver cabin. Power is supplied by cable or slide wire. there are different capacity double beams gantry crane for your choice according to your actually use.
