We are always emphasize the important role of the maintenance of launching gantry, why does us have to maintain the bridge girder launcher? Maybe the users don’t know theBridge building cranes reasons very clearly, so ZZHZ can explain the reason as follow:

 After a long time running , active parts must be abraded , the connecting parts loose, the oil go bad, and the metal structure may be corroded, so they maybe reduce the technical performance , economical efficiency and safety performance.

The aim of the maintenance of bridge building machine is following  :

1, to make sure the good technical performance in order to keep the normal running, improve the intact rate and utilization etc.

2,to make sure the good functional performance in order to enhance the protection of structure, keep the firm connection, keep the electro hydraulic components common action and function to meet the requirements of bridge girder launcher.

3, to make sure the safety.

4.to meet the environmental rules.

5,to prolong the life reasonably.

 So , maintenance takes a very important role in usage of bridge girder launcher.
