Roadway Support Split Set Rock Bolt with Plate

The importance of the face plate as part of an

A well design domed plate will work in a coordinate manner with the rockbolt to absorb energy first,in case of a hit at the collar of the bolt.A face plate that is too strong will immediately transfer the entire load into the bolt head,reducing the energy capability of the bolt for a second hit.Tension Jack/Pull Test Kit - DSI Underground CanadaAnchors,Rock Bolts Pre-Support.CT-Bolt Combination Rock Bolt; AT - Pipe Umbrella System; AT - Pipe Umbrella Automation; AT - TUBESPILE Spiles and Forepoling Boards; Underground Construction.Support Systems.Lattice Girders.3 Bar / 4 Bar; Advantages / Fabrication; Applications; Requirements; Wallplate Beams; Liner Plates; THREADBAR Swellex Rock Bolting System Rock Reinforcement EpirocDesigned and developed to match the perfect rock bolt criteria,the Manganese rock bolt has set a new benchmark for safety and reliability.Made from steel having a richer manganese content,and submitted to a specifically engineered process,Swellex Mn rock bolts have a high tensile strength and improved elongation that provide excellent
