Product Details

 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

 cranes 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
