DN type all-hydraulic computer controlling single cutter soil pressure balance pipe jacking machine

DN type all-hydraulic computer controlling single cutter soil pressure balance pipe jacking machine: To be used in soft soil,hard soil , strong weathered rock and all-terrence soil for pushing pipe and tunnelling with reliable structure and good construction achievement in large calibre pipe pusher. Requirement for backfil depth isnt high,minimum is 1.5 time pipe diameter. May improve soil body and keep control surface steady and land subsidence by means of reasonable grouting mode. Transforms is minimum ,the transportation and treatment for spoil are convenient and easy, good operation environment ,safe operation and fit for large calibre pushing pipe.

Production main characteristic

a. It is mechanical electrical integation high technology production ,technical merit reaches the world class and originate in China.b. Appliance computer full auto , semi-auto and manual drive control in a long distance.c. Power driving system adopts full cylinder proportional control system.d.Adopt laser positioning airmanship,auto skew adjustment ,guarantee pushing pipe project quality.e.Motor start adopts soft start, reduce to interfere with electric fence and to shock to mechanical transmission.f. Use electric element,hydraulic part,reducer,sensor made in the world famous factories to guarantee production quality.g.full auto control program.
