Product Description

1. Application range of Bridge Girder Launcher 
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 bridge girder launcher with double girder. It is mainly used for hoisting (lifting) of concrete girder in bridge construction (bridge building) of general railway and highway.

2. Main features and advantages of Bridge Girder Launcher 
According to users' demands, the new type Bridge Girder Erection Machine which integrates carrying with erecting is designed. Also we apply for national patent (The patent No. Is 02228146.0) 
Features: 
A. The machine can accomplish the girder's carrying with erecting at the same time. 
B. The machine can erect 4 pieces of girders with another two cranes one day, saving construction cycle. 
C. Another advantage: If the concrete girder is between the two piers, just exchange the front and rear legs, it can continue to work, no extra assembly, shortening construction period. 

3. The design basis of Bridge Girder Launcher 
We design the bridge girder launcher according to the rules of the newest machinery and crane in China, the rules are following: 
A. < Cranes--Test code and procedures> GB5905 
B. < Safety regulations for hoisting machinery> GB6067 < Code for design of steel structures> GB50017 
C. < Safety technology specification for special equipment> TSG Q7002\Q0002 
D. < Code for construction and acceptance of steel structure> GB50205 
E. < Standard for quality inspection and evaluation of steel structure engineering> GB50221 
F. < Weld Outer Dimensions for Steel Construction> GB10854 
G. < Code for construction and acceptance of electric equipment installation engineering> GB232 
H. < General technical requirements of assembly> JB/ZQ400.9 
I. < Mechanical properties of fasteners> GB3098 
4. Main design requirements of Bridge Girder Launcher

Working condition and requirements of design etc. 

5. The quality control in Bridge Girder Launcher manufacturing process 
Technology file drawing and project are handed to production department which assorts with related department and quality department to process, manufacture, control, check and accept of product. 
The workshops do the following work according to drawing: 
A. Blanking splicing(technology and requirements of blanking splicing) 
B. Assembling welding(welding procedure card, welding technology qualification and welding record) 
C. Mechanical manufacture(mechanical manufacturing card) 
D. Finishing time of manufacture and patrolling card 
E. Assembly(assembly technology) 
F. Checking descriptive chart(controlling the geometry size and key part).
