CMS’s first Millwright apprentice qualifies

CMS is extremely proud of Ryan Bester, who recently qualified as Millwright apprentice. Ryan is the first of three apprentices to enrol, since the company began its apprenticeship programme.

Ryan will be staying on with CMS, where he will be further developing his already broad skills base and product knowledge.

Revolutionary Auto-Torque device goes into final testing

“Can you provide us with a reliable torque system, that is attached to our bolting machine? Can it ensure that every roofbolt installed is torqued correctly, so that the installed support is not under- or over-tensioned?” This is the question frequently asked when Conax Machine Solutions Pty Ltd interacts with with strata control professionals.

The company is now confident they can answer this question. The company’s patented Auto-Torque Spanner has entered the final stages of testing and CMS hopes to bring a final solution to the market by September 2019.

The Auto-Torque Spanner is essentially a torque spanner with an internal cam arrangement that overcomes at a pre-set axial load, when the desired torque loading is achieved. Tests so far indicate an accuracy of greater than 95%, which is very promising. Traditional load indicators on support members, will be susceptible to greater uncertainty. This is due to greater number variables at play, such as manufacturing process variability, steel batch variability, batch acceptance modelling and installation variables. A number of these devices will also not clearly indicate instances of overloading.

CMS’ Auto-Torque Spanner will be on display at the Local Manufacturing Expo, which runs from 21 to 23 May 2019, at Nasrec, Johannesburg. Visitors can find the CMS stand in Hall 9, stand B6.

CMR4 Prototype nearing completion

CMS is bringing the baby brother of the existing and very successful CMR7 range of the Mantis Roofbolter/Face Drills.

The company’s objective is to position this machine between hand held drilling and botling equipment, and larger, more capital-intensive equipment.

The CMR4 Mantis is expected to have a gross mass of just less than 4 tonne and will be able to bolt/face drill in low seam and standard tunnel development excavations.

CMS expects the CMR4 to launch at a price of roughly 20% to 25% less than the standard CMR7, dependent on the final specification.

The narrow gauge and configuration of this machine will allow it to access narrow roadways alongside conveyor belts for side wall bolting.
