Advantages of us: 1. We use Pressing and Breaking technology,with Mud-Water Balance technology coupled with our own technological breakthroughs, machinery slow speed, torque, to identify the wide range of ability broken. 2 .Diameter of this cuttering head machine can be enlarged after dealing with the case a little. Therefore, one machine can be used in many ways, reducing the investment of equipment. (Simple example: Our 800mm diameter machines, after shell Shell modified and Lengthened cutter, they can work on the 1000mm diameter of the excavation. Soil if the circumstances permit, and even can be improved to 1200) and this is production machinery form other companies could not be satisfied.3 .We have a good project before guiding, teaching, as well as after-sales service: In your pre-construction, you can send people to learn our factory, and then, we will send people to guide you jacking first step of you project.
