| Brief Introduction |
The bridge girder launcher is designed for highway and railway. According to the situation of present railway with less sub-grade, more bridges and tunnels which connected too closely,our company design and manufacture the new box girder bri-dge girderlauncher with double girder.It is mainly used for hoisting (lifting) of concrete girder in bridge construction (bridge building) of general railway and highway.

| Structure |
1.Main girder Be welded of steel plates, connected by high-strength precision bolt. There are sliding rail for trolley to travel upper the girder which is fixed on outrigger by hightension precision bolt. 4. Platform Platform is installed in order to maintain the crane,the protective guard is added to protect the safety of serviceme. This is the considerable device. | 2.Outrigger a.Consist of rigid outrigger and flexible outrigger, all conn ection points are connected by high-tension bolt b. The ladder is used by operator to enter into cab or arriv ing at winch. c.When the span>30m,there need a flexible leg aiming at reducing the lateral thrust the trolley has to the rail when the girder load objects. |
3.Travelling mechanism Consist of driving gear box and passive wheel box a.The driving gear box supplys power to realize the crane’s travelling b.Passive wheel box lacks transmission structure such as dynamo, reducer and a pair of exposed gear 5.Trolley with hoist Be made up of trolley frame, winch and pulley block a.Trolley frame welded of steel plate is the loading and travelling mechanism of trolley with hoisting b.Winch is the lifting mechanism of trolley..when it works, wire rope affects the pulley as rising and falling movement, which makes suspended objects lifting and lowering | 7. Electrical system a.Lifting motor, crane travelling motor and hydraulic power motor are included. The whole electrical system is controlled by PLC. b.Two ways to operate the crane: cab operating and remote controlling. c.Electric components are imported from Germany Schneider 6. Cab a. Glass window through which one can watch overall working condition is installed in the front and two sides of the cab b.Electric cabinet as a group of independent cabinet , fixed out of cab is connected by control cable and linkage station which is set up in the cab |
