Remotely operated roof bolter

The Smart Bolter (electro-hydraulic roofbolter) features individually controlled functions from a push-button remote. The Smart Bolter is only available on the Joy 12ED25 entry driver. The Smart Bolter can be easily programmed to perform controlled automatic cycles: Automatic drilling cycle: operator-initiated once the rig is positioned Automatic bolting cycle: operator-initiated after the drill cycle is complete and the chemical is inserted. The cycle inserts the bolt and torques up to the nut (to pre-defined limits), mixes the chemical, waits for the set time, and then tightens the nut Advanced functions available The Smart Bolter also includes several key advanced functions: Adaptive drilling function: the drill feed speed is adapted to the roof conditions (hard or soft materials) Anti-stall function: when the drill speed slows, the feed thrust also reduces Drill steel bending prevention: the feed pressure is monitored depending on the drill steel type and the depth of collaring into the drill hole Water blockage prevention: the water flow is monitored and the feed rate is slowed if the water flow slows
