Maxi Roof Bolter
The Maxi Roof Bolter is a stope roof bolter for high stope heights designed to clamp between the hanging and foot wall. The Maxi Roof Bolter remote control feature allows the operator to be remote from the drilling rig whilst drilling roof bolt holes in hard rock mining conditions.
- Remote controls with operator removed from drilling position
- One-man operation
- Sting cylinder to lock bolter in position
- Check valve on sting cylinder supply line to prevent inadvertent retraction of sting cylinder due to loss of supply pressure
- Fast drilling due to power of hydropowered drills
- Frame is hot dip galvanised and valves are stainless steel
