Legs are constructed using the same components in the pusher legs for JOY Jackleg drills.
Our Legs employ a three way valve to extend the leg, and hold screen in place at the back.
The valve feeds a continuous supply of air, locking the mesh screen tightly to the back.
The miner has both hands free to install rock bolts through the screen using a Stoper drill.
