new light rail lrt manufacturer truss viaduct construction launching gantry crane

Double truss 1000 ton MTR launching bridge girder erection crane is generally used in the erection of the Highway Bridge and Subway Bridge, using the precast segmental prestress concrete box beam (PC beam) assembly. The main feature is the high efficiency of construction and self-traveling. Generally it is composed of the main beam, leg and winch trolley, the main girder is used for bearing, the leg is to execute machine transverse moving, longitudinal moving, leveling, support, cross span, cross scale and other functions, and the winch trolley used for lifting the precast girder.

  Test before shipment

1.What’s the information should I provide when inquiry about the double truss 1000 ton MTR launching bridge girder erection crane?
a .we need the Bridge Drawing;the Maximum longitudinal slope and the Maximum Transverse slope;
b. The Girder/beam drawing; 

Gradienter：1set                                           
3.What are inspection standard for load test of double truss 1000 ton MTR launching bridge girder erection crane?
a. Dynamic load test
1.1 times rated load, main girder does not down deflection, all mechanisms work well, performance parameters meet the design demand, all limit switches and safety protection interlock devices are reliable, all spare parts does not have cracking and flexible connection, all motors and contactors are not overhead.
b. Static load test
1.25times rated load, all mechanisms work well, the crane stops 20min to 30min as trial load is lifted 10cm high, then measure main girder down deflection(theodolite, ruler). Put down trial load to measure main girder upper camber, repeat 3 times, steel structure does not have permanent deformation.
4.How to make highway bridge concrete girders?
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 double truss 1000 ton MTR launching bridge girder erection crane?
a. Lubricating. b. Steel wire rope. c. Spreader  d. Pulley blocke.Wheels  f. Brake
