The track laying gantry crane is specially designed and manufactured for the laying of 25m rail row of subway (urban light rail), and can also be used for the construction of single crane or the laying of 125m long rail row of multiple linkage laying operations.

The main beam of the machine adopts Yuanbao single box girder as the main load-bearing member unit, and the bolt pair connection is adopted between the units. It is equipped with self-propelled running device and electric hoist lifting device. The structure is simple, and the performance is stable and reliable.

Applicable fields of track laying gantry crane:

The track laying gantry crane is mainly used for track laying and maintenance of subway construction. The track laying machine can realize the height adjustment of the whole machine and the change of walking span by using the hydraulic system drive. The height adjustment range of the whole machine is 3158mm-3808mm, and the span adjustment range is 3000mm-3900mm. It is suitable for areas with an altitude of less than 2000 meters.

The subway track laying machine can not only work together to complete the laying of 25m track row synchronously, but also work alone to lift concrete and other single items.

Characteristics of track laying gantry crane:

1. The machine uses electric hoist to lift and fall through pulley block;

2. During the operation of the whole machine, the braking motor, coupling and worm gear reducer drive the driving wheel to rotate to realize the whole machine to move along the track;

3. The variable frequency speed regulation technology is adopted to realize the stepless speed regulation operation of the gantry crane for track laying and lifting;

4. The machine is not limited by the platform in the tunnel when walking in the subway tunnel, which facilitates the project construction;

5. Simple operation, stable and reliable performance, easy disassembly and transportation, easy to transfer to the construction site, and good economy;

6. According to the user's requirements, the programmable controller (PLC) can be used to control the whole machine and single machine, so that the synchronization performance of multi machine linkage for the laying of 125 meter long rail row is better
