Product Introduction:
ZTE Series EPB is one of National 863 Program’s key projects, as well as one of the State Department’s 16 national key technical equipments. It is the earliest TBM type designed by CRCHI which has the best sales performance. 
CRCHI makes full use of CRCC’s abundant tunnel construction experience, in the field of TBM, developed its own advanced system integration and manufacturing technology, and attended national large diameter TBM science & technology support project and Hunan province heavy equipment development science & technology support project. After several years’ R & D experience, now CRCHI has already fully acquired EPB’s technology of designing, manufacturing and application.  
Based on the reality of domestic tunnel construction, CRCHI optimized its series design; There are two optional driving method for cutter head: electrical driving and hydraulic driving.
According to different geology condition, the designing proposal provided by CRCHI’s R & D can satisfy geology adaptability, using economical efficiency and product reliability. CRCHI can provide excellent after-sales service and technical support. 

Product Features:
Some key technology like control software, system integration and parameter matching, are all independently developed by CRCHI, the TBM can fully achieve reliable performance and convenient operation.
The series type is widely used in the geology condition of clay, sandy soil and soft & hard compound stratum. Its features are high advance rate and low construction cost, it can be widely used in urban metro, mine, water diversion works and other tunnel construction work.
