The McLellan "Bolt Buster "
"Bolt Buster" "THE LINER/BOLT BUSTER" delivers:
That's a lot of productive output without human physical abuse. AS A BOLT REMOVER…Using the impactor and a bolt guide collar, it takes an average of 3 or 4 blows to remove a bolt. Consistently, the bolt
buster has punched out 12 bolts in 10 minutes. AS A LINER REMOVER…A short drift without the collar guide is used to remove liners. If the liner is not dislodged, the Bolt Buster will break it, eliminating any
need for torching. Often, an entire row of liners will fall with only a couple of blows. Cannon Specifications:

Description: The Liner/Bolt Buster has two parts: the Barrel Assembly and a Remote Control Pendant. An overhead crane or optional gantry system, utilized with the pitch attitude adjustment on the unit, positions the head of the Bolt Buster impactor against the liner Bolt (or Liner) to be removed. A spring-loaded collar assists in alignment of the impactor punch to the liner bolts. To prepare the Bolt Buster for Firing, the Load button on the Remote Control Pendant is pressed. This returns the projectile to the rear position for firing. To fire the Bolt Buster, the Arm and Fire button are pressed at the same time (for safety). The fire button opens a valve that releases compressed air into the Bolt Buster Barrel. The air propels the projectile down the barrel onto an impactor punch that strikes the liner bolt (or liner). If the bolt is not removed on the first hit, the procedure is repeated. Once the bolt is ejected, the Bolt Buster is positioned with the crane on the next bolt. A variety of replaceable drifts may be used to extend the Impactor reach. The same drift is used to remove liners. Due to the simplicity of the unit general repairs can be done at the job site by un-skilled labor
