South Africa’s mining sector has faced opportunities and challenges, with some mining houses thriving due to rising prices and demand for commodities and others grappling with declining markets, oversupply and logistical constraints in recent years.
These challenges have led many mining companies to experience dips in revenue and profits, driving them to seek innovative solutions to improve efficiency, productivity and profitability.
Against this backdrop of seeking efficiencies, Performance-Based Standards (PBS) vehicles with advanced engineering and customisable designs have emerged as a game-changer for key mineral sectors, including copper, lithium, heavy mineral sands, and uranium.
This is according to John Kettlewell, CEO of Unitrans Mining Division, speaking ahead of the Mining Indaba, themed ‘Investing in Africa’, which takes place in Cape Town from 3-6 February.
As an early adopter of the technology, Unitrans operates a fleet of over 50 registered PBS vehicles, serving the petroleum, mining and agricultural sectors.
"The advantages of PBS vehicles are undeniable," said Kettlewell.
"Their success lies in matching the right vehicle to the right operation. Each vehicle is designed to perform tasks with maximum productivity, safety and sustainability. This tailored approach ensures the specific requirements of each mineral are met, enabling optimised payload capacities.
"Bulk material handling in mining is inherently complex, with challenges often tied to the physical and operational demands of moving massive quantities of materials efficiently and safely."
PBS vehicles can transport up to 140 tonnes, enhancing payload capacity. This capability reduces trips, alleviates congestion at loading and offloading areas, and lowers carbon footprints.
By optimising vehicle configurations and achieving higher payloads, Unitrans has achieved over 20% reduction in fuel consumption per tonne hauled and a 54% decrease in the number of vehicles required for a mining operations customer.
PBS vehicles also play a pivotal role in improving safety. Studies show a lower crash involvement rate per kilometre travelled than conventional trucks. Enhanced stability, manoeuvrability and braking systems make them ideal for navigating the tough terrains of mining operations.
PBS vehicles also minimise road wear per tonne-kilometre and offer increased gross- combination mass and cubic capacity. These innovations enhance productivity while lowering transport costs and fostering a more sustainable supply chain.
"While transitioning to PBS vehicles involves upfront investments and specialised training, the long-term benefits far outweigh these challenges. These vehicles have transformed transportation efficiency, safety and environmental impact, aligning perfectly with the evolving demands of the mining sector,” said Kettlewell.
"As the mining industry continues to evolve, the integration of PBS vehicles will play an increasingly vital role in shaping a more efficient and sustainable future.”
