Secure Haul Truck Suppression Technology For Sound Control

Key Takeaways

• Haul trucks generate significant site noise from engines, exhaust, cooling systems and vibration, so suppression is critical for compliance and productivity.
• Effective haul truck noise control should reduce emissions without compromising airflow, back pressure, reliability or serviceability.
• Custom suppression packages work well because they target noise at the source with truck-specific components instead of one-size-fits-all fixes.
• Fleet-wide noise management is more practical when solutions cover mixed OEM fleets and extend to other mobile and fixed assets.
• Testing, ISO-aligned verification and ongoing maintenance support help link attenuation outcomes to audit-ready evidence and long-term performance.

Haul truck suppression focuses on reducing noise levels associated with this mobile asset, a concern often encountered in industrial mining operations.

For this reason, Minetek offers engineered sound packages designed for compliance and community responsibility.

Whether you need a Liebherr muffler or packages for other OEMs, we provide reliable, cost-effective suppression systems tailored to your needs.

Haul trucks generate high noise loads, but they remain essential to production.

These are powerful vehicles that perform heavy-duty cycles. As such, without haul truck suppression, noise often accumulates from their high-power engines, exhaust flow, cooling systems and vibrations during loading, hauling and tipping.

For many Australian sites, managing this noise is crucial to meet community expectations and adhere to site noise limits without affecting productivity. Effective industrial suppression systems become a necessity as these trucks are an integral part of production operations.

Neglecting truck noise attenuation also impacts more than just one area. Elevated acoustics can lead to operator fatigue while complicating environmental reporting and audits. Whether you’re in need of Westrac sound attenuation or solutions for other OEMs, the primary goal is to keep vehicles operational where they are needed, safeguard the workforce, and maintain regulatory and community expectations.

Our haul truck sound packages reduce noise emissions.

We work to control noise while protecting machine performance and OEM airflow, so sound reduction is achieved without introducing the typical trade-offs that can lead to overheating, back pressure issues or hard-to-maintain installations.

Ultimately, through our vehicle sound suppression solutions, we aim to enhance the acoustic environment without compromising the truck’s reliability and serviceability, especially under demanding mining and industrial conditions.

Our custom heavy truck suppression packages are also engineered comprehensively. Targeting noise at its source through carefully planned component design, we avoid one-size-fits-all solutions. With this, key sound suppression elements may include:

• dual-skinned exhaust system
• radiator attenuator
• bumper extension where required
• left and right-hand engine panels
• belly panel
• horseshoe attenuation
• bonnet attenuation
• tray body sound media panels.

Compatibility across OEM fleets keeps noise control practical at scale.

Minetek’s heavy equipment suppression seamlessly adapts to real fleet mixes and allows mining sites to tackle noise as a whole.

In operations that include multiple models, applying tailored haul truck suppression is key. That’s why we deliver sound attenuation solutions for over 90 OEM models, fitting more than 3,000 mining machines globally.

Haul truck suppression coverage includes renowned models such as Caterpillar 770 through 798 series trucks, Hitachi EH 3500 to EH 5000 and B series trucks, Komatsu 730E through 980E and HD series trucks and Liebherr T 264 through T 284 trucks.

When it comes to suppression system installation, compatible brands also span across industry leaders like Terex, Sandvik, LeTourneau and others.

In line with this, we extend beyond sound suppression for haul trucks. You can look to us to engineer custom systems for mobile and fixed assets, such as excavators, dozers, blast hole drill rigs, graders, loaders, water trucks, generators and acoustic enclosures.

Whether you need a Hitachi exhaust system or a similar solution, our coverage allows sites to address accumulated noise across the fleet and fixed plants, not just haul truck noise.

Verification and support are treated as part of the sound solution.

Identifying the primary noise source and a practical mitigation pathway is crucial when noise becomes a concern. That said, we provide noise testing specifically designed to identify the issue.

Solutions are backed by compliance testing in line with ISO 6393/6395 standards. For Environmental Compliance Managers, this testing-led approach is invaluable. It offers sound intensity testing, mobile fleet screening and operator noise exposure testing, enabling a clear link between chosen haul truck suppression solutions and the evidence needed for audits and internal approvals.

Post-installation, we remain a steadfast partner, delivering technical support and maintenance.

We stay with you, offering technical assistance, troubleshooting, field service and maintenance options tailored to the dynamic environment of busy mining sites. Whether you need a Komatsu muffler or solutions for similar OEMs, our focus helps with continuity on busy sites, where maintenance windows are planned tightly and unexpected noise creates disruption.

Plus, we maintain a stock of replacement truck noise suppression parts and accessories, allowing for quick responses to equipment failures. This avoids costly downtime, keeps your operation running smoothly and helps ensure that your noise attenuation systems remain effective throughout their working life.

Domande frequenti (FAQ)

Does haul truck suppression add significant weight to the build?

Effective noise suppression does not have to weigh haul trucks down. Our M-STEALTH™ noise management system achieves strong noise reduction while preserving key functional elements like payload capacity, airflow and OEM back pressure requirements.

With high-performance suppression systems for heavy equipment, the engineering process focuses on practical compliance. This helps ensure that no unnecessary mass is introduced, as certain additions could affect the productivity of day-to-day operations.

Can older haul trucks get customised noise control?

Yes, older haul trucks can be fitted with customised noise control systems, and they often benefit the most from sound suppression upgrades.

As trucks age, wear and tear can amplify noise levels due to factors like loosened fitments or decreased exhaust efficiency. We use sound intensity testing and acoustic visualisation to identify specific noise sources in these older models. Then, we engineer a turn-key solution tailored to target those problem frequencies and provide attenuation, whether for a Liebherr exhaust system or other OEMs.

Do you have sound packages for other types of trucks?

Yes, Minetek offers sound packages for varied truck types beyond the typical haul fleet. Our truck-specific solutions, like the custom water and service truck sound package, are designed to tackle operating noise across different functions.

For mine and industrial sites, these solutions support dust control and visibility activities while helping meet noise compliance across operating areas and times.
