Question:

I would like to know the working principle of JQ IV 160t/40m bridging machine?

I would like to know the working principle of JQ IV 160t/40m bridging machine?

Answer:

Working principle: the front assembly, the central assembly and the longitudinal moving flat car assembly are equipped with rotary 0-45 angle of the rotating support to meet the requirements of the bridge girder oblique beam. When the bridge erecting machine is inclined to set up, it is necessary to pre install the central cross beam and the middle part of the roll, the front cross beam and the front roll, the trolley beam and the crane in the angle of oblique installation.
The guide beam is composed of double girder truss, a connecting pin, a connecting frame, the front rear connecting frame, wire rope fixing rack etc.. The guide beam is arranged on the lower part of the central assembly (including 2 active flat, middle, middle oil shake rolled flat top), tail assembly (including 2 tail oil top and tail legs and tail bearings), front assembly (including 2 sets of active front roller, flat, flat front beam wave temporary support, front). The upper part of the two guide beam is welded with a track, and the track is provided with 2 longitudinal shift flat car assemblies. The guide beam is arranged inside the platform, or via bridging machine can go through temporary support from Taiwan to the top cap.The longitudinal moving flat car assembly is a single track active flat car, each longitudinal shift flat car assembly is controlled by the electric circuit to realize the longitudinal walking. Can be used alone, can also be used online.The moving car is composed of two parts: the walking mechanism and the lifting mechanism. The lifting mechanism is used for hoisting and the traveling mechanism realizes the lateral displacement.
JQ IV 160t/40m bridging machine:JQ bridge erecting machineType fourth, refers to the step type bridging machine160t - rated lifting weight 160t (2 x 80t)40m - allows the erection of the maximum span of 40m
