SRC Series
APPLICABLEDIAMETER:800-4000MM
APPLICABLE GEOLOGY:PEBBLW,GRAVEL,SOFT ROCK
* Independent cutter head center scour system
* Reliable displacement space shear crushing structure
* Reasonable cutter design makes the pebble particle size effectively controlled
* Stable and safe power system provides enough power for crush pebbles

SPB Series
APPLICABLE DIAMETER:500-4000MM
APPLICABLEGEOLOGY:SILT,SAND,CLAY
* Applicable to all kinds of normal soil, such as silt, sand, especially for strata with high ground water level and large soil variation range.
* The construction excavation surface instable, low disturbance to the soil around the pipe jacking, low subsidence of the ground.
* The slurry transfer system has strong continuity and the jacking construction speed is fast.
* Remote operation controlled on the ground, full automatic response within the machine head, more safe, standardized and convenient.
* The spindle seal is reliable and has a long service life.


EPB Series
* Applicable to different kinds of normal soil with low ground water level.
* Adopting low speed and high torque transmission mode with greater excavation force, and the overload coeficient can reach more than 3.
* Independent and perfect water injection and grouting system improve the excavation surface soil condition to expand the scope of application.
* The construction ground settlement is small, and the minimum thickness of the overburden layer is only 1.2 times of the pipe diameter.
* The center-supported cutter head, compact structure, light weight, long service life, and convenient maintenance.
* Unearthed by the screw conveyor, with a high amount o f excavation and large particle size.
* Steering controlled by the advanced electrical system operated easily and response sensitive, digitally displayed, intuitive and reliable.
* Full-section cutting, large aperture ratio.
