MEGABolt Water Expandable Rock Bolt (ERB)
The MEGABolt Water Expandable Rock Bolts range features friction bolts with superior product characteristics to meet the most demanding roof support applications. The high-load bearing capacity and excellent elongation properties ensure safer working conditions and faster excavation cycles for low costs.
Reinforcement with Water Expandable Rock Bolts occur by hydroforming (i.e., expanding) the bolt with high-pressure water against a drill hole wall. Water Expandable Rock Bolts expand into the hole shape when water at high pressure is pumped. The bolt expands to create a friction and interlocking anchor. MEGA Bolt’s ERB provides immediate full load-bearing capacity with safe and easy installation. Installation is easy and flexible to fit various drill hole diameters.
The MEGABolt Friction rock bolks are manufactured according to the ISO 9002 standards. Each batch and finished rock bolts are texted to ensure final quality.
The MEGABolt Friction Range consists of three products that provide 30% elongation:
- Standard for lighter applications with load capacity of 12 metric tons (120 kN)
- Midi with a load capacity of 16 metrics tons (160 kN)
- Super with a capacity of 24 metrics tons (240 kN)
