Product Description
300 ton railway beam launcher machine erecting girder is used in the erection of precast beam bridges for span by span method of construction for precast beam girders like T beam, U beam, etc. This self-beam launcher is suitable for bridge construction over river, valley or highway and so on.
300 ton railway beam launcher machine erecting girder is suitable for the construction of bridge for roads, railways and other bridge erection construction site. Its main function is to lift the prefabricated beams, then transported onto the prefabricated pier. It has big difference from the general cranes. It requests high security.

Packing
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 300 ton railway beam launcher machine erecting girder are suitable for container ship, usually by container;
2.If the size is too big, usually by bulk ship or by container after truncation; Transport ways are based on reducing cost for you and keep the crane performance.
Delivery time
Within 30 to 40 working days after the receipt of deposit.
Transportation
Generally 35 days to 50 days to destination port.
FAQ
1.What’s the information should I provide when inquiry about the beam launcher?
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 300 ton railway beam launcher machine erecting girder?
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
1.25times rated load, all mechanisms work well, the crane stops 20-30min 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;
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 300 ton railway beam launcher machine erecting girder?
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 beam launcher in the worksite we need?
Personnel: 8-10 workers equipment:
Truck crane>50t:2 sets
Φ19.5 steel wire rope 8m:4 ropes
Sleepers:Several
Electric welding machine:1set
Oxygen, acetylene:1 set
Hammer(12pound and 8pound):1 set for each
Wrench and pincher:Several
Gradiometer:1set
