Product Details


Product Description:

For a complex underground or mix, of a composition varying between rock with low resistance and medium resistance, our pipe jacking machine excavation chamber is equipped with a cone crusher. From the cutter head excavation the clod and stones enter into the crushing chamber, to be crushed by a secondary crushing device, the cross arm in the process of rotation breaks the debris, reduce to minimum diameter to fit the outlet line, simultaneously mixed with water for slurry excavation.


Application Scope: 

Gravel, Limestone,Cobblestone,Mix etc.


Main Features: 

The cutter head adopts cross arm structure , greatly improves the speed into slurry chamber, besides, the cross arm includes high pressure water nozzle and improves hardness of the excavation face and the efficiency.

In addition to the body adding welding wear layer, the wear resistance layer height 3-5mm, hardness above HRC56, the tungsten carbide welding adopts silver blade brazing and greatly improves bond strength of cutting tools, brazing strength over 245Mpa



The advantages of our equipment


1.The shell thickness is not less than 25mm so as to avoid any deformation. It is made as a whole part, not pieced together.

2. Power Box:

2.1 The main axle material is 42CrMo and its gear never breaks.

2.2 Good sealing ensures that mud water will not enter the power box.

2.3 Use of ultrasonic flaw detection ensure no occurrence of cracks and achieve triple flaw detection.

2.4 It's a complex processing from rough finish, forging, heat treatment, flaw detection to fine finishing and chroming.


3. PLC electronic control system

3.1 Humanized design with USB interface under control desk (console) for charging

3.2 PLC program is programmed with motor protection and 5-second delay for fast stop under both clockwise and counterclockwise motor running so that the gear will not be broken for sake of gear protection.

3.3 PLC intelligent control can take a three-day record of operator’s deviation correction in case of unnecessary dispute after any accident.


4 Hydraulic valves.

4.1 The hydraulic valve Brand is BMEG, with good hydraulic stability.

4.2 Hydraulic lock ensures no pressure release.

4.3 Separate hydraulic stations, motor, pump ,oil tank separated for easy maintenance.


Technical Advantage:

1. Main drive can be driven by a hydraulic motor, with high torque, high reliability, power and technical parameters are based on Herrenknecht and MTS.

2. Main drives adopts Swing bearing design, it has the same design and function as Herrenknecht and MTS, but with low-cost value.

3. Backup system adopts automatic guidance system as similar as VMT

Tunneling Data Acquisition and Recording System
