Highway or railway Road construction machine for MRT beam launcher

Highway Bridge erecting machine, highway or railway road construction machine.
Applied to the construction of the highway. The highway bridge erecting machine is the equipment of putting the prefabricated bridge beam on the prefabricated pier. Because it's main function is to lift the bridge beam and transport it to the specified location, so it also belonged to the bridge crane category . But it's also big different from the normal bridge crane , because it's harsh conditions and working on the beam or called lengthways moving.

Packing & Delivery
1. Electric parts are packed by high quality plywood crate, to reduce distortion in conveying;
2. Main beams, end beams and electric hoist are packed by plastic woven cloth. It can reduce abrasion when transport.

Delivery:
1. If the size of whole Highway or railway Road construction machine are suitable for container ship, usually by container;
2. If the size is too big, usually by bulk ship or by container after truncation;
3. Transport ways are based on reducing cost for you and keep the crane performance!

FAQ
1.What’s the information should I provide when inquiry about the Highway or railway Road construction 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 Highway or railway Road construction machine?
2.1.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.
2.2.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?
a.Full span prefabrication,
b.Segment girder prefabrication
c. Full span cast-in-place girder
d. Segment cast-in-situ
4.How about maintenance of Highway or railway Road construction 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.
5.How many Personnel and equipment to assemble Highway or railway Road construction machine in the worksite we need？
Personnel: 8-10 workers Equipment:
Truck crane>50 t ：2 sets
Φ19.5 steel wire rope 8 m: 4 ropes
Sleepers：several
Electric welding machine: 1set
Oxygen, acetylene：1 set
Hammer (12 pound、8 pound): 1 set for each
Wrench and pincher: several
Gradienter: 1 set
