Hava - Air LEG Pusher

HAVA Pusher Leg is used along with a Wet Rock Drill Machine in drifting and tunneling operations for inclined and horizontal drilling. The feed cylinder of steel and the rugged, simple design of the parts of the feed guarantee operation without disruptions and reduce maintenance cost to a minimum. The feed pressure is regulated with a control valve on the air inlet which is both throttle and shut-off valve. The feed pressure can be unloaded by means of a button-operated relief valve.
