PREFABRICATED LIGHT-WEIGHT BORING MACHINE

摘要

PURPOSE: A prefabricated light-weight boring device is provided to reduce the construction period and manufacturing cost. CONSTITUTION: A prefabricated light-weight boring device comprises a light weight endless track(10), a perforation guide(20), a hydraulic motor(30), convey units(40a,40b) and a power device. The light weight endless track conveys a boring device main body. The perforation guide is mounted on the light weight endless track and guides a perforation drill bit. The hydraulic motor is attached to the perforation guide and generates the torque of the drill bit. The convey unit controls the location of the hydraulic motor and perforation guide. The power device supplies the hydraulic power to a punching device stand through a hydraulic hose.
