Montrae Mining Shock-Cusion Subs are used in angle and vertical drilling operations for reducing vibration and ware in rotary heads and drilling rigs. The unique design allows soft connections of rod threads and decreases the impact on rotary heads and masts.
Montrae Mining has now developed 6 different sizes of Shock-Cusion Subs to suit any Drill Rig Configuration. All 6 have achieved fantastic vibration analysis results and exceptional feedback from on-site staff. All subs can be fitted with a Montrae Mining Locking System
