Metro Track laying crane, China good quality dt10t gantry crane, track laying

Product Specification

In order to meet the needs of China's urban subway construction and meet the needs of all kinds of subway track laying construction, our company is committed to the R & D and manufacturing of supporting railway engineering machinery.

Dt10 metro track laying machine is a self-developed mechanical equipment for metro track construction, with lifting capacity of 10 tons and adjustable span of 2980mm-3900mm; The height of the whole machine is adjustable from 2950 mm to 3650 mm. The machine is suitable for working in the environment with altitude below 2000 meters, working temperature - 30 ℃ ~ 50 ℃, humidity ≤ 90%, no fire, explosion and corrosive medium. The overall dimension of the metro track laying machine can meet the requirements of metro equipment construction clearance, and has the characteristics of stable start, safe and reliable braking, which can be operated by two sets of joint operation or one set of independent operation. When two metro track laying machines work together, 25m track can be laid; When a single metro track laying machine works, it can lift concrete and other items with a single weight of no more than 10 tons. The traveling part of the crane adopts frequency conversion speed regulation, and the equipment starts smoothly; The motor has its own braking device, which can ensure the safe and reliable braking of metro track laying machine on 35 ‰ ramp (customized all wheel drive track laying machine can meet the requirements of 50 ‰ ramp, which is only applicable to new tunnels due to the limitation of overall width); Using cable reel power supply, safety and environmental protection.

The metro track laying machine has a hydraulic system, which drives the hydraulic cylinder to adjust the height of the whole machine and change the running gauge of the whole machine. By using flat car and tooling support, the whole machine can realize automatic span and height adjustment in the tunnel; And rotate 90 ° After the use of flat car transit transportation.

Technical features

1. Light and flexible, simple operation, stable performance.

2. It is convenient to pass through platform, civil air defense door and curve.

3. The equipment connection is simple and reliable; The circuit and hydraulic pipeline are connected by quick connector, which is convenient for installation and disassembly.

4. The main girder can be hydraulically expanded and span changed, between 3m-3.9m, with 5 groups of parameters to choose from.

5. The gantry can be lifted by hydraulic pressure, the equipment is 3.808m, and the height is 3.158m. The implementation of the above scheme has solved the problems such as free span change without disintegration of the track laying crane in the tunnel, whole machine assembly and disassembly of the flat plate, transit transportation and subsequent construction of the liaison channel, etc.

6. The traveling frequency conversion control can realize single speed, double speed and frequency conversion control according to the user's requirements.

7. Frequency conversion and two speed control ensure smooth operation of the equipment and neat alignment of the track. Using large square power supply cable solves the problem of voltage drop, which can ensure that there is no voltage drop within 3km.

8. Due to the realization of the walking frequency control and lifting double speed control, gantry lifting and variable span full hydraulic control, the operation process is simplified, and the work efficiency and safety factor are greatly improved. According to the field test of tunnel, the whole process of lifting, changing span, loading and unloading plate is completed within 10 minutes without dismantling the cross hanger.

9. Using high standard material configuration, the whole machine has light weight, small volume and large lifting capacity.

10. It is equipped with cross spreader to lift rail row and concrete pouring hopper.

Application field of metro track laying machine

The metro track laying machine is mainly used in the track laying and maintenance of metro construction. It is a new product independently developed by our company. The product 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 the area below 2000m. The track laying machine can be used for two sets of joint operation to complete the 25m track laying at the same time, and can also be used for lifting concrete and other single items separately
