Rubber tyred gantry crane is a special machine for stacking and yarding operations of containerized goods. It consists of gantry bracket, power transmission system, lifting mechanism, trolley running machine trolley running mechanism and telescopic spreader and so on. Container spreader equipped with walking trolley along the main beam track walking, container loading and unloading and stacking operations, tire type line it walk mechanism can make the crane walking in the yard, and can be 90°right-angle steering, from a yard to another yard transfer, flexible operations.
Rubber tyred gantry crane is suitable for loading and unloading of large span, frequently railway freight yard, port, open storage, container transfer station etc. It is suitable for heavy bulky cargo and container handling operations, with frequent high-level work, A5 ~ A8. The capacity is from 5 to 500 tons, span is from 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.
According to the drive mode heavy duty gantry crane can be divided into a diesel-electric mode and a diesel-hydraulic mode. Diesel an electric way is driven by a diesel engine DC generator, DC generator driven DC motor, and then drive the various institutions. Diesel engine a hydraulic way is driven by a diesel engine hydraulic, hydraulic pump driven by a hydraulic motor, and then drive the various institutions, the way of acceleration performance is good, the weight of the power unit but the system is prone to oil leakage, maintenance is more complex, less use.
The hevy duty gantry crane 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. It can work independently or collaborative work by two units.
Efficient container loading and unloading along railroad tracks. High stacking capacity to maximize vertical space. Precise positioning and alignment of containers. Reduced floor space requirements compared to other gantry crane types.
