1.What’s the information should I provide when inquiry about the 900T launching beam railway bridge launcher machine?
▪we need the Bridge Drawing, the Maximum longitudinal slope and the Maximum Transverse slope.
▪The Girder/beam drawing.
2.How many kinds of construction methods for bridge launcher?
1. overhead segmental.
2. underslung segmental.
3. balanced cantilever erection segmental launching gantry.
4. full span.
3.What are inspection standard for load test of bridge launcher?
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 overheat.
b.Static load test
1.25 times rated load, all mechanisms work well, the crane stops 20-30 min as trial load is lifted 10 cm 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?
Highway Bridge concrete girders could be made by 4 methods:
▪Full span prefabrication.
▪Segment girder prefabrication.
▪Full span cast-in-place girder.
▪Segment cast-in-situ.
5.How about maintenance of bridge launcher?
a. Lubricating. b. Steel wire rope. c. Spreader. d. Pulley block. e. Wheels. f. Brake.
