Mech-Lok Bolt - Dynamic 20 mm
Features:
- The 47 mm Mech-Lok Bolt Dynamic 20 mm Hybrid Friction Bolt is designed for easy installation in poor and difficult ground conditions, such as squeezing and seismic ground conditions
- Easy installation, even in collapsed drill holes
- Specialty steel to maximize capacity and energy absorption Energy dissipation minimum 32kJ - Energy dissipation Typical 58kJ
- Typical Bar Elongation 25%
- Manufacturing using proven high elongation 20mm bar
- Dynamically tested using the Jennmar 105kJ
- Dynamic Test facility Increased system capacity utilizes a combination of mechanisms working together
- The resistance of the 47 mm Friction-Lok along the length of the bolt along with a unique expansion shell design improving energy dissipation and impact resistance
- Inclusion of a solid internal bolt increasing load bearing capacity and shear resistance
- Energy absorbing ring retains internal bolt in premature shearing failure mode
- No changes required to existing drill rigs for installation
