For HI-TEN Strand Bolts

 

General Features

  • These roof bolt installation spanners are purpose designed for the installation of Hi-Ten strand bolts.
  • This spanner incorporates an internal 14.0mm square female socket to match the mixing square on the Hi-Ten bolts. The set distance from the top of the spanner to the internal drive square provides the optimum bolt tail length required for placement of the hydraulic tensioning unit onto the bolt after installation.
  • The spanner drive end and the mixing square socket are manufactured from high tensile material for strength and wear resistance.
  • Four (4) small holes are provided through the body at the bottom of the internal socket to allow flushing with water if internal cleaning is required.
  • Each spanner is also manufactured from a heavy duty tube to provide durability.
  • These installation spanners are available as standard in nominal overall lengths of 300mm.
  • Please refer to your DSI Technical Service Engineer for details of product codes if alternate spanner lengths or special drive ends are required.
  • All DSI installation spanners are assembled on a mandrill to ensure concentricity with the machine rotation.
