The long and dynamic function sleeve of NMX Dynamic 2.0 enables energy-absorption near the rock face.
NMX Rock Bolts
NMV Group has been designing and manufacturing rock bolts for specific fields of application since 1968.
Our dynamic rock bolts NMX Dynamic and NMX Dynamic 2.0 are constructed with a thread that is thicker than the diameter of the rest of the bolt. This unique design means that the thread of the bolt can never break, ensuring the stress-relieving function of the washer on the exterior of the rock mass.
Among our products is also the tried and tested NMX Static, the Kiruna Bolt, which has been described as a link between efficiency and safety. The Kiruna Bolt has been used in Sweden’s underground mines for over 40 years and is known for its unique time- and cost-saving qualities.
A testing programme performed at our in-house testing facilities ensures the quality of our rock bolts.
