Form of drawing trolley is adopted to achieve light structure,advanced performance, high production efficiency, fine maneuverability and small sensibility to unflatness of the ground. The crane is powered by cable drum. At the same time, diesel generating set is equipped for conditions when the power is off or the crane moves to another yard. As a result, maximum economic benefits are brought to the users.

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.

Rubber

Top-quality rubber, good abrresistance. Flexible turning. Tyre protection device.

Lifting Trolley

High working duty hoist mechanism. 

Control Cabin

The entire crane adopts Schneider variable frequency speed regulation and Siemens PLC control system. Equipped with remote monitoring RCMS and operation functions.

Container Spreader

Adopting high-precision container cranes handling suitable and loading/unloading international standard containers(or twin-ift spreader if needed).

Features:

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;

5. Travel mechanism: With China or world famous crane motor, reducer supplier, such as Nanjing motor, SEW etc;

6. Electrics: Chint, Schneider or Siemens etc.

Rubber-tyred Container Gantry Cranes are applicable to remove, load and unload international standard containers.

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.
