The jib of jqj160t-40m highway bridge erecting machine is composed of left and right box girders, which run through the fuselage and extend forward and backward. There are folding columns composed of two legs at both ends. There are two truss cars across the two box girders, which can travel along the boom longitudinally. The trolley is placed on the truss car and can travel along the truss car. The beam to be erected (or the whole beam) can be directly sent to the rear arm of the bridge erecting machine by the railway flat car, lifted by the beam trolley, moved forward by the truss trolley, then moved horizontally by the beam trolley, and then dropped into place. The front and rear ends of this kind of bridge erecting machine can lift and drop beams; When changing the direction of beam erection, there is no need to turn around; In order to adapt to the curve beam, both the front and rear arms can swing in the horizontal plane; When erecting in pieces, the beam can be in place without moving the beam or shifting the track“ "Beam feeding" also does not need a bifurcated line at the bridge head or a special beam carrier. Track laying should be done immediately after girder erection, so that the bridge erecting machine can continue to work forward. The latter two kinds of bridge erecting machines can generally hoist the pre assembled track rows in place, so that the beam erecting work will not be delayed due to track laying.

Features of jqj160t-40m highway bridge erecting machine:

It is mainly composed of bridge, cart running mechanism, trolley, electrical equipment, etc. According to the frequency of use, it can be divided into A5, A6 and A7. The operation of hook bridge crane is completed by the driver.

Lifting height of jqj160t-40m highway bridge erecting machine: 6-22m.

Design advantages of jqj160t-40m highway bridge erecting machine:

1. The first honeycomb beam design, with light weight, large load, strong wind resistance and other characteristics.

2. Unique steel pin connection, not only firm and reliable, but also short assembly time.

3. Flexible rod legs, site steering can be disassembled into a single piece, convenient transportation.

4. Due to the small installed capacity, the difficulty of power consumption in field construction is solved.
