Bridge Girder Erection Machine Description

JQ Road Launching Gantry is a professional construction machinery, which is used to transfer the road concrete precast blocks and bridge beams to the position of abutments or supporters, and then built road or highway bridge.

It composed of horizontal moving girder devices, main girders, support system, vertical moving gantry devices, horizontal moving gantry devices, hydraulic system and electrical control system.

Highway bridge is the highway bridge prestressed concrete beam tablet or beam section lifting to bridge bearing on the special construction machinery. Mainly by the beam longitudinal shift flat car assembly, girder components, support system, the longitudinal shift system, the transverse system, hydraulic system, electric control system components.

Main girder is commonly double beam truss structure. At present domestic highway bridge structure form in roughly the same, the main difference is that the longitudinal guide beam bridge form and via way. According to the longitudinal guide beam forms can be divided into single guide beam bridge and double guide beam bridge, according to the via form is divided into LunGuiShi bridge and walking machine.

Parts Details of Bridge Girder Erection Machine

Bridge Girder Erection Machine Parameters

Bridge Girder Erection Machine Advantages

♦ It's light weight, transportation, installation and removal is very convenient

♦ The Beam Launcher represents a good stability, high efficiency, safety and reliability, easy to adjust variable cross and easy to operate

♦ The legs do not through the bridge deck when longitudinal move, no need to lay vertical moving orbit, reduce the pressure on the deck

♦ It has three method picking up the precast beam: from rear end of the beam launcher on the deck level, from below on ground level, or from bridge side

Bridge Girder Erection Machine Safety Features

Shenghua BL Series are designed for safety. Winches are equipped with double breaking system. Upon request we provide Triple breaking system. Emergency stop button, Limit switch, sensor are located at designated location. Lighting and spare-parts are part of the items coming with our beam launcher.

Packing and Delivery

Packing methods:

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 methods:

1. If the size of 150 ton concrete T beam launcher 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 150 ton concrete T 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 150 ton concrete T beam launcher?

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 150 ton concrete T beam launcher?

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 150 ton concrete T beam launcher in the worksite we need?

Personnel: 8 to 10 workers equipment

Truck crane > 50 t : 2 sets

Φ19.5 steel wire rope 8 m: 4 ropes

Sleepers: several

Electric welding machine: 1 set

Oxygen, acetylene: 1 set
