These roof bolt installation spanners are purpose designed for use with Flexibolts in their installation and subsequent tensioning.
The spanner socket is compatible with DSI’s patented "rim cone" system. This system allows the Flexibolt to be tensioned up to 5 tonnes on installation.
The spanner drive end and socket are manufactured from high tensile material for strength and wear resistance.
Each spanner is also manufactured from a heavy duty tube to provide robustness and internal clearance for rock bolt drive nut inserts.
These installation spanners are available in nominal overall lengths from 400 mm to 1800 mm.
All DSI installation spanners are assembled on a mandrill to ensure concentricity with the machine rotation.
Packaging
Shorter spanners supplied as required in hessian bags or cardboard boxes.
Longer spanners steel strapped together with up to 5 spanners per bundle.
