Super Turbo Bolter And associated drilling equipment for mining and civil engineering
Highest performance at light weight
Minova manufacture a range of compressed air operated, telescopic leg type drilling/bolting machines. These are lightweight, high performance machines, which were developed originally for the mining industry.
The design of the machines makes them readily adaptable to different types of drilling and bolting applications, and as such they can be used in the tunnelling and civil engineering industries. The machines offer flexibility, rapid set-up, lowmaintenance and operation costs and ease of use.
Minova are able to provide design proposals for the mount and operation of machines to suit different application.
• Rock bolting systems - Resin capsules, roof bolters and bolts • Ground support - High volume output grouts for strata support • Sprayable membranes- Polymer systems for strata control • Strata injection systems - For ground consolidation and water sealing

Minova 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 roofbolts and long tendons, and is supplied in five standard sizes.
Benefits to the user:
•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 the 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 andless 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.
