Description

Product Description

Traveling underslung bridge launching gantry crane
traveling underslung bridge launching gantry crane was developed and designed by our Design Department for high speed railway bridges construction (250 km/hour and 350 km/hour).

The feature of traveling underslung bridge launching gantry crane:

1. light weight

2. good stability

3. precise self positioning

4. precise beam positioning

5. easy operating

traveling underslung bridge launching gantry crane comes with Centralize control system, Multi speed Crane, Hydraulic powered Support, Mechanical powered Self Advancing system and spare-parts.

Packing & Description

Paching & Delivery of traveling underslung bridge launching gantry crane

Packing:

1. Electric parts are packed by high quality plywood crate to reduce distortion.
2. Main beams, end beams and electric hoist are packed by plastic woven cloth to reduce abrasion during transporting.

Delivery:
1. 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 traveling underslung bridge launching gantry crane?

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 traveling underslung bridge launching gantry crane?

2.1.Dynamic load test

2.2 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.
2.3Static load test
2.4times 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?
Highway Bridge concrete girders could be made by 4 methods:
3.1.Full span prefabrication
3.2 Segment girder prefabricationull span prefabrication,
3.3 Full span cast-in-place girder
3.4 Segment cast-in-situ
4.How about maintenance of keywords$?

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.
