WORLD PROSPECTS
With its unique curved design and innovative use of materials, the Hercules mining truck bed“ is lighter yet stronger, offering miners numerous advantages, including a demonstrated payload increase above 10 % and a significant service life extension”, the company says. Schlam attributes its success to its focus on innovation, advanced engineering design and delivering on the individual needs of customers.
Over 2,500 truck beds have been produced to date – primarily in Australia – with growing global demand for Hercules having driven Schlam’ s strategic expansion into international markets such as North America. Schlam has also delivered over 600 truck beds for autonomous truck fleets in Australia and the United States.
Schlam said of the Canadian delivery:“ With years of experience supporting hard-rock miners globally, we’ re looking forward to seeing Hercules excel in this new environment. We will monitor the bed’ s performance and continue to implement new optimisations to increase payload, reduce downtime and deliver value for the customer.”
Outside of North America, Schlam also recently celebrated the delivery of the 300th Hercules truck bed to Fortescue, and the delivery of the 300th Hercules truck bed to Glencore.. www. schlam. com
New MSHA silica rule shifting emphasis to engineered cabin air solutions
The mining industry is facing a pivotal moment with the introduction of MSHA’ s updated respirable crystalline silica standard, according to BreatheSafe. With the tightening of permissible exposure limits and redefinition of expectations around dust control, the rule is driving a fundamental shift away from reliance on personal protective equipment towards robust, engineered solutions that prevent contamination at the source.
This change casts a spotlight on operator cabins – often assumed to be safe havens from dust but frequently challenged by the fine silica particles generated during mining activities. As a result, mining companies are compelled to reconsider cabin design and air quality management to ensure genuine protection.
BreatheSafe says it has responded with in-cab air filtration solutions that focus on keeping contaminants out at the source, creating sealed and positively pressurised environments that support clean air throughout the shift.
“ By combining high-efficiency filtration with intelligent airflow management and real-time monitoring through its OnGuard
8 platform, BreatheSafe enables operators and site teams to maintain consistent cabin air quality without adding complexity to daily operations,” it says.
“ The system uses individually tested H14 HEPA filters, integrated with OEM heating and cooling systems, and is supported by custom installation components that maximise airflow and sealing. OnGuard’ s real-time air quality monitoring delivers alerts and operational visibility, empowering
proactive maintenance and compliance.” BreatheSafe’ s engineered approach provides a reliable, verifiable pathway to fullshift exposure control, protecting workers while supporting operational uptime, adhering to MSHA’ s published rule and guidance:
• PEL( Permissible Exposure Limit): 50 µ g / m ³, averaged over an eight‐hour TWA.
• Action level: 25 µ g / m ³, also over an eight‐hour TWA.
• Additional requirements:- Mandatory exposure monitoring;- Use of engineering controls first;- Updated respiratory protection standard; and- Medical surveillance for MNM miners
It is offering up an example from a global client to put colour behind this statement.
“ In Tier-1 iron ore regions, environmental conditions present a relentless challenge to both human health and machinery longevity,” it says.“ For operators of ultra-class equipment, such as the Hitachi EX3600-7 hydraulic excavator, the primary antagonist isn’ t just the hard rock; it’ s the invisible, airborne respirable dust that permeates even the most modern cabins.”
Despite rigorous air-conditioning service intervals, a prominent iron ore site found that fine particulates were consistently bypassing standard seals and OEM filtration systems. This posed a dual threat: The site required a solution that could maintain positive cabin pressure and high-level filtration without requiring constant manual intervention or specialised operator training, with a customised BreatheSafe clean-air system being integrated into the cab. Unlike standard HVAC units that recirculate internal air with limited fresh intake, this system uses a multi-stage approach to atmospheric control, the company says. This includes:
• Positive pressure control: An automated OnGuard monitoring system maintains a consistent pressure barriers ensuring that dust-laden air is physically pushed away from cabin seals;
• HEPA grade filtration: The system incorporates high-efficiency HEPA return air filters, capturing sub-micron particles that standard filters often miss;
• Intelligent monitoring: Real-time telemetry tracks CO 2 levels and particulate matter( PM10), providing a data-backed audit trail for safety compliance; and
• Quantifiable impact: maintenance and wellness.
Following the commissioning of the BreatheSafe system, the operational data revealed significant improvements in both cabin environment and maintenance overheads: Maintenance costs fell by 30 % related to HVAC-related expenditure, the filter longevity service life extended up to 1,000 hours, dust ingress was reported as zero during technical inspections and there was full alignment with international occupational health standards.
BreatheSafe concluded:“ In an industry where the health of those on the front line is paramount, engineered cabin air systems are no longer optional add-ons; they are essential components of modern mine safety and operational excellence.” www. breathe-safe. com
Pronto’ s AHS hauls > 2 Mt on mixed fleet at Heidelberg Lake Bridgeport
Pronto. ai, Inc., last month, announced a significant milestone in the digitisation of the aggregates industry, with Heidelberg Materials having autonomously hauled over 2 Mt of limestone at its Lake Bridgeport quarry in Texas.
Following a successful pilot project at its Bridgeport site, Heidelberg Materials has equipped a mixed fleet of Caterpillar and Komatsu haul trucks with Pronto’ s Autonomous Haulage System( AHS). Leveraging an AI-first approach to autonomous technology, the site safely transported an amount of material equivalent to the weight of around 20,000 fully loaded freight train cars in under eight months. Pronto says this this achievement establishes a new commercial standard for operational velocity and flexibility in quarry automation.
