RPCF Rotation Pressure Controlled Feeding

 Continuously monitors and adjusts the feed pressure
according to the rotation pressure
 If the rotation pressure continues to increase beyond a pre-
defined upper limit, the rock drill is pulled back and starts a
new collaring in the hole

Anti - Jamming automatics

FPCI Feed Pressure Controlled Impact

 The percussion pressure is only allowed to ramp up
full impact level when the feed pressure is above a
certain ”contact” level and the drill bit is properly
pressed against the rock.
 Reduces the impact pressure when the feed pressure
goes under a certain ”contact” level
