PV Solar Installation by CMS

A recent electrical fire at a council substation resulted in a power outage to our area that lasted for a little over three weeks. During this period, CMS made use of diesel powered generators to power the Industrial Park.

After the resumption of power supply, there have been numerous “nuisance” power outages. This lack of power supply reliability and the state our national power grid, prompted Zonax Holdings, to install a PV (photovoltaic) Solar solution that would keep the offices running, in the event of a power outage.

Zonax management then tasked CMS with designing, installing and commissioning a 10 kW Solar PV solution. The solution had to be scalable, modular and also provide undercover parking for staff.

Final commissioning, integration and optimization of the system was achieved in the second week of July 2020. A 5 kW expansion of the system is being considered. Longer term, post the COVID-19 pandemic, Zonax will consider installing a 350 kW, 3 phase Solar PV solution. This size of installation would power most of the machinery installed in the Industrial Park. But for now, we can rest assured that our offices will have uninterrupted power.

Mobile Drilling Platform – to facilitate safer and more efficient, secondary support installations.

The Mobile Drilling Platform is multipurpose.  The working deck is made with heavy duty, nonslip expanded metal. The platform has a safe working load (S.W.L.) of 2,500 kg and a maximum capacity for four people on the working deck.

Height and leveling adjustment of the platform is provided on each corner with a landing leg unit, having an external and independent adjustment via an internal bevel gear arrangement.

Access to the working area is provided by a vertical ladder which extends to the height of the safety railings and combining safety hoops.

Operator safety on the platform is ensured by the provision of safety railing on all sides.  Entry is provided via a lockable gate which pivots inwardly. Kick plates are provided on all sides.

The platform can be towed from both ends. Each towing assembly has a steering arrangement that can be disabled. Easy movement over rough ground is achieved by the use of wide, industrial grade, air filled tyres.

Important features & benefits of the Mobile Drilling Platform:

  • Quick and easy deployment to work areas
  • Ability to drill directly from the work deck
  • Safer and easier access to the mine roof
  • Greater control of portable drilling equipment when drilling
  • Work deck space accommodates four people, permitting parallel preparation of mining consumables whilst drilling / installing support.
  • Increased productivity
  • Various height adjustable options available to suit varying roof heights
  • Strong and robust construction
  • Platform construction is a bolted together assembly that is easily stripped down for road transport.
  • Certified design and load tested

CMS Designs, Builds & Installs Pillar Jib Crane for Emergency Service Vehicle

Our client required a pillar jib crane for a closed body, truck trailer. This crane will be used for loading and offloading items from an emergency services training vehicle. CMS designed, built and fitted the crane to the customer’s specifications, as well as arranged for a professional engineer’s fit for purpose certificate and the statutory load testing.

The jib crane has been fitted with a 220V electrical hoist that is powered by the truck genset. It has a safe working load (S.W.L.) of 300kg, a travel of 1,800mm and a swing range of 200 degrees.

Special Purpose Drill Rig for Highwall Face Pinning at Heights

Specialised support installation company, SENTINEL SUPPORT PTY LTD, required a solution that would enable them to drill into and support a highwall face. At heights of up to 27m, to help them meet this challenge, CMS fitted one of its CFP240 drill feedframes to a MAGNI RTH 5.30 Telehandler.

Using some intelligent valving, CMS was able to use an auxillary hydraulic circuit on the telehandler, to power the drill rotation and feed.

“IMPI” – Multi-purpose Piling & Drilling Rig

CMS has manufactured the IMPI to be a multi-purpose, mini piling and drilling rig. It is exclusively marketed and supported by IMPI PILING & DRILLING EQUIPMENT PTY LTD.

This IMPI rig is ideally suited for:

  • Solar panel piling,
  • Armco barriers,
  • Auger drilling,
  • Top hammer drilling &
  • DTH drilling applications.

CMS Manufactures Ground Breaking RADIALcvt Gearbox

Conax Machine Solutions has an agreement with VARIBOX, the intellectual property owners, to manufacture and commercialize the RADIALcvt gearbox. The RADIALcvt is an incredible innovation that solves a lot of the problems experienced with existing CVT gearboxes.

The first unit produced by CMS is a 30kW, 200N.m gearbox. Our intention is to deploy this unit into a Conveyor or other Material Handling application. The gearbox is currently undergoing testing at the University of the Witwatersrand.

The advantages of the RADIALcvt over conventional drive systems are profound. The RADIALcvt has a very high mechanical efficiency, in excess of 90%. It is a variable ratio, mechanical gearbox that is continuously variable. The ratio can be varied under full load anywhere from 3 : 1 to 1 : 1. Ratio actuation can be manual or automatic. As a result, the following are some of the distinct advantages:

  • The need for a mechanical or electrical soft start device is done away with, the RADIALcvt acts as a soft starter
  • As a result, smaller electric motors can be selected
  • Smaller motors require less start up power, lowering power demand charges and switchgear overhead
  • Due to the >90% mechanical efficiency of the RADIALcvt, power consumption is lessened, which can be a very significant cost-saving over the lifetime of the installed equipment.

CMS is actively looking for a willing business, operating in the bulk material handling space, where we can run a trial project on a non-critical part of their operation. For example: a discard conveyor or other process with redundancy.

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.
