1. TIANDI HEAVY INDUSTRIES (Here after refer as "THI") cooperate with MITSUBISHI HEAVY INDUSTRIES(Here after refere as "MHI") to develop and manufacture Shield Machines to satisfy booming underground engineering constrcution requirement.

2. Shield Machine is the key equipment for underground traffic expend engineering project (Metro system) and underground telecommunication, electriction, Oil & Gas, Mining, Water piping system project. with the flexible, harmonious development object, and for the increasing underground linking system for the morden society, deeper underground space development is essential. THI import the most advantage underground engineering technology into China to meet the demand of urban constructions.

3. THI's current Shield machine has two type as follows, we can design different size of shield machine according to customer need.
    3.1 SS (Slurry Shield Machine)
    3.2 EPB(Earth Pressure Balance Shield Machine)
