Product Introduction

Tunnel Frame Column Type Pneumatic Rotary Drilling Rig

pneumatic frame column use press air as power,use rotary motor control valve control the rotary motor.Compressed air drive the gear motor’s rotation.After the two-stage reduction drive spindle rotation in order to drive drilling work.By supporting cylinder valve control cylinder and loosen tight top.This machine is powered by compressed air, when used, ure 0.63MPa.Should stop reliably close the intake valve to prevent turning mechanism automatically open
