The movement of whole-section tunneler is composed of forward movement of tunneler body pushed by the crowd cylinder and rotational movement of disk-cutter driven by the rotating motor.
全断面掘进机工作时的运动主要由推进液压缸推动机身的前进运动和旋转电机带动刀盘的转动组成。
The thrust of crowd cylinder on tunneler is the main design parameter to determine the number and dimension of crowd cylinder on tunneler and the basis to determine propelling force of tunneler work.
掘进机推进液压缸的推压力是确定掘进机推进液压缸缸数和液压缸大小的主要设计参数，也是确定掘进机工作中推进力大小的依据。
