MP1 Bolt

MP1 Bolt

Description

The MP1 Bolt is an encapsulated, end-anchored yielding bolt for mechanised installations. The end anchor provides immediate support upon installation with additional anchorage post-encapsulation of the installed MP1 Bolt.

To aid mechanised installation, the end anchor is shielded by a steel sleeve and is only activated once the MP1 Bolt is fully inserted into the support hole.

The MP1 Bolt is provided with a load indicator to confirm correct tensioning of the unit when installed. The MP1 Bolt can accommodate a secondary push on or screw on mesh washer.

A specially designed system ensures easy mechanised or manual encapsulation of the installed MP1 Bolt with minimal spillage during pumping of resin or grout.

Benefits of the bolt

  • High energy absorption
  • Immediate support
  • Pre-tensionable with load indicator
  • Easy encapsulation with reduced spillage
  • Can include attachment points for meshing and lacing directly onto the bolt
