SupHulk Rock Bolt-SupAnchor

 

SupHulk TM Swell friction bolts are used for the strengthening of rocks in mining and tunneling construction. 

The bonding to the rock results from the friction which is formed between the extended bolt and the rock. 

Friction bolts can be subjected to the full load directly after they have been positioned and are immediately able to absorb the rock movements.

The carrying force is applied along the complete length of the inserted bolt..

- PM12 -

  Premium line (PM)
   

- PM16 -

  The Premium line is a typical tunneling bolt, with a high yield load and good deformability. Pm rock bolts can also be used in mining when low to medium stress conditions require a stiff  SupHulk TM  rock bolt with a high yield load.
