  Our Box type bridge girder crane overhead launching gantry machine lifts, transport and position the Full Span Bridge in few simple steps. Shenghua’s scope of delivery of FSM equipment covers the design and supply of the complete range of equipment typically needed in such constructions: Special formwork with inner mound(hydraulically maneuvered),Lifting cranes for pre-cast yard, Lifting cranes for pre-cast bridge span, Multi-axle tyre trolly, FSM launcher.


 1. What’s the information should I provide when inquiry about the Box type bridge girder crane overhead launching gantry machine?

1.1 We need the Bridge Drawing, the Maximum longitudinal slope and the Maximum Transverse slope.
1.2 The Girder/beam drawing.


2. What are inspection standard for load test of Box type bridge girder crane overhead launching gantry machine?
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. 
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.


3. How to make highway bridge concrete girders? 
Highway Bridge concrete girders could be made by 4 methods: 
3.1 Full span prefabrication.
3.2 Segment girder prefabrication.
3.3 Full span cast-in-place girder.
3.4 Segment cast-in-situ.


4. How about maintenance of Box type bridge girder crane overhead launching gantry machine? 
4.1 Lubricating: Working performance and service life of all mechanisms of crane depend on lubricating to a big extent.
4.2 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. 
4.3 Spreader: The spreader has to be checked regularly 
4.4 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 
4.5 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 
4.6 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.
