Product Description

The rubber tire type container gantry crane(RTG,also known as yard/field bridge) is a specialized machinery used in large specialized container yards to load and unload standard containers. It is not only applicable to container terminal yards, but also to container dedicated yards.

Equipped with diesel AC generator set for power supply and digital variable frequency speed regulation, it can move in two directions within the container yard. Equipped with telescopic slings capable of lifting 20 foot and 40 foot containers. In general, the span of the field bridge has been standardized to 23.47 meters (six lanes plus walkways), and non-standard span field bridges can also be supplied. The lifting height can ensure the lifting of a 40 foot high 9'6" container, crossing four layers (or five to six layers) of the container stack.
The traveling mechanism of the crane can be four-wheel or two wheel drive. To prevent collisions between yard bridges and between yard bridges and containers, a manual deviation correction system and anti collision devices at the four corners of the crane are installed.
The mechanical operation of the small car can adopt rack and pinion type or dual axis or single axis drive, ensuring smooth operation. There is a cab under the small frame, where the driver operates the entire crane.

Safety Feature of RTG Crane:
Automatic rectify deviation control
Weight overload protection device
Top quality polyurethane buffer
Phase protection
Lifting limit switch
Cross traveling limit switch
Long traveling limit switch
Voltage lower protection function
 

High Reliability:
The motor,Frequency converter and reducer are imported from domestic and international famous brands with industry recognition, quality assurance.
The main electrical components is from the selection of Siemens, ABB and other international well-known brands, the protection degree electronic control box is no less than IP54.
 

Advanced Manufacturing Technology:
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 radio graphic testing and ultrasonic testing to ensure the welding quality.
 

 

Modular design:
 According to the general rules of products, components, it forms the hoisting mechanism modeule, trolley traction mechanism module, trolley assembly module,steel structure module, founction module, general module and etc. 
The standard module production ensures product stability of quality and shortens the delivery cycle.
