Rubber Tyre Container Gantry Crane
Rubber Tyre Container Gantry Crane(RTG ) is suitable for loading and unloading of large span, frequently railway freight yard, port, open storage, container transfer station etc.This machine adopts U type gantry, its legs headroom large (nearly 7 meters). It is suitable for heavy bulky cargo and container handling operations, with frequent high-level work, A5 ~ A8. The weight of 5 to 500 tons, the span of 18 to 35 meters, the girder can be designed have cantilever and no cantilever, the end of two main beam connected with end beams to meet the high level requirements.
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.
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 with horizontal layout. The rubber Tired gantry crane can work independently or collaborative work by two units.
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.
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.
Following technical specification is for reference.
Spreader is for container 20`, 40` and 45`. |
