rail welding yard gantries for rail synchronous lifting

Rail welding yard crane design

Special design multiple gantry cranes for long rail handling at rail welding yard to realise synchronous liftingGrey Busbar Displacement Detection System (GBDDS) Introduction:

The multiple gantries system can reach:

1.synchronous hoisting movement for long rail hoisting without twisting it
2.100m-500m rail handling
3.crane group
4.remote control
5.2-3 worker operation

In order to solve the problem of lifting long welded rail from 100~500m, we put up a now solution: Combined Crane Grey Busbar System. It is the combination of cranes and wireless displacement detection system. This system can ensure the accurate move of the rail from up & down, left & right, forward & backward direction to prevent from distortion..

The crane group consists of gantry cranes or overhead cranes. They can be traveling or fixed type. 8 gantry or overhead crane can lift 100m long rail and 20 cranes can lift 300m long rail.

The control is also easy and efficient. 3~5 workers are enough to control the crane group, pendent control or remote control.

Grey Busbar Displacement Detection System (GBDDS) uses flat Grey bus bar and electromagnetic coupling between antenna boxes to detect, locate and communicate data. It's a very mature non-contact absolute position detection data communication sensor technology.

It consists of four parts: Grey Busbar, Antenna Boxes, Address Code Generator and Address Decoder. Grey Busbar likes a ruler with scale, Antenna Boxes similar to pointer, pointer location is the current position. No need to set original reference point. It has a five millimeter location accuracy, able to do make-and-break or continuous detection, especially for uneven rail or circular motion location detection. Generally, Grey Busbar is installed beside the rail, Antenna Boxes fixed on crane. Position value can be received on ground or crane. Address information can be transferred via own sensor, data radio or signal cable. One Grey Busbar can used on multiple movable machines and the length can be designed by project requirement. Several pieces of Grey Busbar can be connected together.

With the performances of water-proof, grease-proof, dust-proof and anti-erode, it has no theoretical life cycle, widely used for severe environments like metallurgy, hydraulic engineering, open-pit mines, stockyards, port terminals, non-ferrous metal and petrifaction and so on.
