Description

 Specification
1. Due to the adoption of the planetary gear reducer in a single electrical motor-operated form (the planetary gear reducer keeps up with the international trend with a large train ratio and high reliability), the Cutter head works with high efficiency, low calorific value, and good reliability. Furthermore it is small in size, so it is easy for operation, installation, maintenance and management of the machine.

2. The main devices inside the machinery, such as mechanical transmission system, hydraulic system, sludge-discharge system and electric controller, etc., can always serve several purposes, which absolutely satisfy the needs of a variety of calibers with the diameter from **0mm to **0mm. Therefore, it benefits the general domestic users a lot with the minimum investment in the early stage.

3. The structure and dimension of the mechanical transmission system is adapted to the space of theФ**0 Pipe-Jacking machinery; the strength and service life of the whole system can also satisfy the construction requirements of Ф**0 Pipe-Jacking machinery. Especially, it can serve the particular demands of Pipe-Jacking Tunneling Machine in start-up with heavy loads.

4. The machinery system is controlled from the ground with remote-controlled operator. The electric-controlled system includes the data acquisition system and PLC. It takes touch-screen operation with display function. The design of highly integrated operation structure can improve the processing property of the machinery. At the same time, it is able to lower the workers labor intensity.

5、Its second-breakup function allows the Pipe-Jacking machinery work in special geological conditions (e.g. soil mingled with small pebbles or gravels.)

6、The cutter teeth are mainly flat. The cutter tip adopts the high-strength and high abrasion-resistance hard alloy with good impact toughness.
