It’s now possible for small-to-medium-sized surface mining operations to capitalise on the benefits of digital technology. Michelin has just introduced an entry-level version of its tyre pressure monitoring system (TPMS), which delivers operational optimisation and safety enhancements for lower capital expenditure – MEMS LITE.

Smart technology is proving to be a game-changer in mining as the Fourth Industrial Revolution – characterised by data utilisation, high-speed networking, and cloud technology – comes to fruition in the sector. Michelin has been a leader in this regard with its TPMS offering, which is now in its fourth generation: MEMS4.

But smaller operations and contractors who move from one mine to the next require a solution better suited to the scale of their operations. MICHELIN MEMS LITE is just that – an entry-level TPMS ideal for contractors and mining operations with smaller dump trucks (typically below 150 tonnes).

How does MEMS LITE enhance productivity?

MEMS LITE employs Michelin’s proven tyre pressure and temperature monitoring technology to give smaller mines more control over the mobility side of their operations, with greater oversight of their vehicles and equipment. It enables the remote monitoring of pressure and temperature to help extend the lifespan of a mine’s tyres and prevent premature failure.

This allows mines to curb operational costs by getting more mileage on their tyre budget while also reducing unscheduled vehicle downtime. The disruption to productivity caused by a vehicle sitting idle represents a significant expense, and for smaller operations with fewer trucks that impact is amplified.

The data that MEMS provides helps mines to better manage their maintenance schedules, supporting their efforts in terms of preventative maintenance that avoids costly unscheduled stoppages.

How does it enhance safety?

Another key benefit is the ability to improve safety. This is achieved primarily by reducing the need for personnel to do manual pressure and temperature checks on the ground where sudden tyre failure poses a serious danger. Remote monitoring allows personnel to remain at a safe distance while gathering this data.

Alerts via email and SMS to connected devices (any laptop or tablet) help operations managers stay ahead of potential problems, putting information at their fingertips in real time, allowing them to make timely decisions and reduce risks. In addition, vehicle handling and responsiveness can be improved by ensuring that tyres are being used at optimal pressure, further enhancing safety for operators.

How does it work?

MEMS LITE requires no hardware installation on vehicles, which makes it budget-friendly and simple to install. As vehicles drive past fixed reading stations, diagnostics data is collected from durable sensors inside the tyres (which are compatible with liquid additives) and is then transmitted to the mine’s local server or to a secured cloud server where it can be easily accessed by personnel.

These reading stations have a range of up to 100 metres with a clear line of sight, are simple to set up and can be easily relocated, providing a high degree of flexibility. The sensors can be used on all tyres, either through the “MEMS-ready” feature on Michelin tyres or with a retrofit patch for non-Michelin tyres or tyres smaller than 49”.  

Why opt for MEMS LITE?

Mines with a limited staff complement, an unsatisfactory amount of unscheduled downtime due to tyres, a high number of tyres wearing out prematurely, too many casings that can’t be retreaded, and those wishing to improve their level of safety should certainly consider this solution.

Not every mine requires continuous data readings. For many, the periodic tyre pressure and temperature readings MEMS LITE offers will suffice. However, upgrading to MEMS4, if or when the time comes, is a simple process. Mines that lack technical expertise will benefit from the user-friendly nature of the technology, as well as the availability of Michelin support teams for guidance, optimisation and on-site training.  

The numbers alone make a compelling case for it. Tyre budgets typically represent up to 20% of a mining vehicle fleet’s operating costs. Improved tyre pressure management that reduces pressure deviation by 20% can result in up to 25% more lifespan. That can translate into as much as R3.6 million in potential savings on an annual tyre budget of R18 million. Add to that the value of demonstrating higher safety standards and even advancing progress on sustainability targets with reduced tyre wastage.  

In short, MEMS LITE helps to protect people and the planet as well as profits, presenting a win-win scenario that delivers on the promise of 4IR technology. What’s more, it does so without requiring the level of upfront investment that would be beyond the reach of smaller operations.
