The subway track laying machine is a kind of gantry crane specially designed for the construction of subway track engineering. It is mainly used for track row lifting, template, steel bar lifting and installation work; the construction site is generally a narrow space such as a subway section.

It can realize the adjustment of the height of the whole machine and the change of the walking span by using the hydraulic system drive. The height adjustment range of the whole machine is 3100mm-3600mm, and the adjustment range of the span is 3000mm-3900mm, which is suitable for the altitude below 2000 meters.

The subway track laying machine can not only work with two units, to lay the 25m rail row simultaneously, but also work alone to lift concrete and other single items.

Applicable Industry:

1. Construction of subway track engineering for track row lifting, template, steel bar lifting and installation work; narrow construction site, subway section.

2. According to the construction characteristics such as the hoisting load status and frequency of use of the track laying machine, the working level of the whole machine is selected to be A3 level or above.

3. According to the requirements, the track-laying gantry crane has the functions of automatic span and height change; to meet the needs of the current construction operation conditions of various subway tunnel track projects, the track-laying crane can pass through the platform, screen door, small curve bends, and communication channels. It can be transported in the tunnel without disintegration.

4. The relative humidity is 55% to 85%; the flammable gas concentration does not exceed 10% of the minimum explosive concentration. The ambient temperature is -25℃～+40 ℃.

Performance:

1. Easy installation and operation, low maintenance cost;

2. Adjustable running speed and high handling efficiency;

3. Simple operation;

4. Compact structure, suitable for small space operation;

5. Strong versatility, suitable for all types of subway tunnels;

6. Automatically changing the span and height;

7. The whole machine can be transferred without disassembly.

Subway gantry crane for slag handling is used for subway tunnel construction. This crane is mainly responsible for the construction of the subway tunnel, lifting the dregs excavated by shield excavator to the ground. Features of subway slag gantry crane:

◆ variable span, improve crane utilization;

◆ cantilever detachable, more practical;

◆ running fast, high work duty, high efficiency;

◆ high lifting height;

◆ with special tilting spreader with automatically tipping.
