1. Electric and hydraulic parts are packed by high quality plywood crate to reduce distortion in conveying;
2. Main beams, end beams are packed by plastic woven cloth. It can reduce abrasion when transport.
1.If the size of Overhead truss type segment launching gantry crane are suitable for container ship, usually by container;
2.If the size is too big, usually by bulk ship or by container after disassembly.
Transport ways are based on reducing cost for you and keep the crane performance.
1.What’s the information should I provide when inquiry about the Overhead truss type segment launching gantry 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 launching gantry in the worksite we need?
Personnel: 8 to 10 workers equipment:
Truck crane>50t :2 sets
Φ19.5 steel wire rope 8m:4 ropes
Electric welding machine:1set
Oxygen, acetylene:1 set
Hammer(12pound and 8pound):1 set for each
Wrench and pincher:several
3.What are inspection standard for load test of Overhead truss type segment launching gantry 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 800 ton segment china launching gantry equipment for bridge construction?
a. Lubricating. b. Steel wire rope. c. Spreader d. Pulley blocke.Wheels f. Brake
