Product Description

150t 160 ton u type subway bridge erecting beam launcher crane is a professional design for U type bridge machine required for erection of city rail transit construction beam. As a kind of structure section, the U beam has good noise reduction effect, low construction height, high utilization ratio of cross section space. Because of U type beam for thin-walled opening structure, the traditional bridge rack beam cannot be applied directly. Unable to realize the traditional function of carrying beam traversing, beam body installation can only be achieved by traversing the crane. Therefore Huada Heavy Industry U type bridge erecting machine with "front overhead crane beam, acquired vehicle girder, two cranes synchronous walking, then synchronized fall beam" of the process, simple operation, safe and stable.

U model bridge girder beam launcher crane is mainly used in the Inter-city railway building projects, such as metro way, light rail transit, etc. As economy and public transportation develop, inter-city railway is vigorously building in developing countries, such as China, Indonesia, Philippine, Vietnam, Myanmar, Russia, Kazakhstan, etc.

As the great project of “One Road One Belt” implement deeply, this “U” girder beam launcher cranes are of great potential market in the world.

“U” bridge girder is just like a tunnel without cover; which not just largely reduces the overall height of the viaduct bridge structure, but also largely shield the train noise.

FAQ

1. What’s the information should I provide when inquiry about the 150t 160 ton u type subway bridge erecting beam launcher crane? 
a.we need the Bridge Drawing;the Maximum longitudinal slope and the Maximum Transverse slope; 
b.The Girder/beam drawing;

2. How many Personnel and equipment to assemble 150t 160 ton u type subway bridge erecting beam launcher crane in the worksite we need?

Personnel: 8 to 10 workers equipment
Truck crane > 50 t : 2 sets
Φ19.5 steel wire rope 8 m: 4 ropes
Sleepers: several
Electric welding machine: 1 set
Oxygen, acetylene: 1 set
Hammer(12 pound and 8 pound): 1 set for each
Wrench and pincher: several 
Gradienter: 1 set

3. What are inspection standard for load test of 150t 160 ton u type subway bridge erecting beam launcher crane? 
Dynamic load test: 1.1 times rated load.
Static load test: 1.25 times rated load.

4. How to make highway bridge concrete girders? 
Highway Bridge concrete girders could be made by 4 methods: 
a. Full span prefabrication.
b. Segment girder prefabrication.
c. Full span cast-in-place girder.
d. Segment cast-in-situ.

5. How about maintenance of 150t 160 ton u type subway bridge erecting beam launcher crane? 
a. Lubricating: Working performance and service life of all mechanisms of crane depend on lubricating to a big extent. 
b. Steel wire rope: Fracture of wire has to be specially noticed. A new steel wire rope has to be changed immediately with the condition of broken wire, broken strands and wear loss to scrapping standard. 
c. Spreader: The spreader has to be checked regularly. 
d. Pulley block: Mainly check rope race wearing condition, check whether wheel flange is cracked and whether pulley could get stuck in the axle or not. 
e. Wheels: Regularly check wheel flange and tread, a new wheel has to be immediately replaced as crack part or wearing in wheel flange reaches 10% of wheel thickness; Re-polishing has to be done as diameters between two driving wheels on tread differs more than D/600, or there are severe scar on the tread. 
f. Brake: Check one time per shift; The brake should be in accurate movement, and pins do not allow to be stuck. Brake shoes shall fit brake wheels correctly; the brake shoes interval shall be equal to open them.
