Launching Gantry Crane

タイトルまたは説明

Our range launching girder is an important machinery for building high rise constructions, bridges etc. These launching girders can handle cat-in place concrete, as well as prefabricated elements, hence they are highly adaptable for varied spans and types of superstructure. With sophisticated design & fabrication, these launching girders are itself a steel structure, which moves forward on the high rise constructions or the bridge piers span by span. With varied launching capacities and heights, our range of launching girders are made using quality material, ensuring durable and reliable performance.

Launching cranes are widely used in the following applications:

1.     Bridge construction

2.     Highway construction

3.     Railway construction

4.     Road construction.

Design features include:

1.      Reliableperformance

a)        Apply the latest separate pinned structure of triangular space truss to main girder, so as to improve the stiffness and strength of whole crane.

b)       Main girder is made of Q**5 high strength steel, and melt into the latest design to ensure the main girder can work under high strength mode safely.

 

2.      More powerful corrosion resistance

a)        Strictly execute standard painting process to ensure blasting and painting quality.

b)       Apply H steel enclosed section for main girder chord. Web chord is made by customized square tube to realize enclosed welding, which can avoid inner rust.

3.      Higher working efficiency

a)        There is traveling rail together with main girder, trolley and longitudinal crane. So, it is no need to lay traveling rail more. In this way, a lot of auxiliary materials are saved and production time is also saved.

b)       ZHONGJIAN launching crane has higher working efficiency, with 6~8 pieces girder erection every day, based on enough concrete plate supplying, skilled operator and good condition at site.

4.      More flexibility

a)        It is symmetrically designed. Two way girder erection can be realized without split and slewing at original place.
