Super Turbo Bolter

      The flagship of the Minova range of machines is the Super Turbo Bolter, which has been designed for the drilling and installation of roof bolts and long tendons, and is supplied in five standard sizes. Benefits to the users:
    • Leg Extension
    • Due to the side mounting of the motor the design of the Super Turbo Bolter enables it to achieve greater extension on two leg stages than other machines on 3 stages. This is very important since there is almost 50 % more thrust developed when drilling or installing a bolt using Super Turbo Bolter as compared to other machine types which require a 3rd stage leg for similar reach. Other benefits of this design arrangement are faster drilling times and less drill steel changes.. Impact Resistant and Hard Wearing Leg Material The Super Turbo leg assembly is made of fundamentally different materials and construction technique when compared to other machines which gives it a much longer operational life and resistance to damage. This gives the user longer machine availability rates and reduces leg replacement costs.
    • High Performance Piston Motor
    • The Super Turbo Bolter is powered by four cylinder high performance and low maintenance motor. This motor design gives higher and consistent power output with longer service intervals.
    • Light and strong
    • The careful selection of materials and design allows the Super Turbo to be the lightest and strongest machine available which enables it to operate reliably and effectively in even the toughest mining environments.

GOPHER

GOPHER” bolting machines is rotary pneumatic machine reliable in every situation. It is a manually operated rotary, low-pressure machine with a three-stage leg operation. A range of machines cover operational heights of between 1.08m and 3,51m. The Gopher will operate with pressures between 400 kPa and 620 kPA and can be used with the appropriate drill rods for dry or wet drilling. Typical applications include mining, quarrying, tunneling and civil engineering.
