We can overhaul your noisy, non-compliant fleet. Providing you with sound suppression and attenuation solutions that maximise maintenance crew accessibility is our specialty. We also aim to reduce attenuation equipment weight and upfront costs where possible. Our team is highly skilled at fabricating OEM replacement exhaust systems and creating thermal lagging packages.

Sound services and strategies

As a result of our unique expertise, we provide sound suppression and attenuation services such as:

  • Consultation and noise control strategies
  • Reliable end-to-end project management
  • Design, engineering, acoustic modelling and fabrication in-house
  • Noise testing before and after deployment
  • Installation assistance and onsite support
  • Replacement parts and ongoing support

Design-driven innovation

We strive to achieve best-in-class designs for sound suppression and noise attenuation. Innovation in design and engineering helps us find solutions to problems for our customers. In our research phase, we dig deep to uncover opportunities. We focus on unrestricted maintenance access, weight-saving solutions, and modular design.

Project management – make or break

We provide comprehensive project management services and work closely with our clients throughout the project lifespan. If you want to avoid getting bitten after signing a contract, consider this crucial aspect.

A typical project involves working through the following steps to achieve noise compliance:

  • Project scope
  • Acoustic partner (see project management below)
  • Design stage
  • Fabrication stage
  • Prototype stage (including design revisions)
  • Fleet implementation

Providers like Global Acoustics and Thearle Engineering can perform independent sound tests to verify compliance.

Sound success and on-site support

Providing sound suppression solutions for haul trucks is one of our specialties, and we have a solid track record. We have achieved resounding attenuation successes with the Komatsu 830E, Liebherr T282, Caterpillar 777D, 785B/C, and 793D. We have experience designing, building, and installing exhaust silencers for excavators, including OEM upgrades for Caterpillar 6060 and Komatsu PC4000.

We provide ongoing assistance

We have a reputation for providing reliable after-sales support. Support is a key part of our commitment to our customers after the final product is installed and compliant. Nothing is more frustrating than discovering that a supplier fails to provide after-sales support and spare parts. Among our commitments are the following:

  • Site-specific parts catalogues
  • Installation resources and fleet audits
  • Technical support and fast response time
  • Australia-wide on-site support
  • Spare parts reliability (in-house fabrication)
Aletek advantage

Our Commitment

As engineers and fabricators, we take our jobs seriously. Design Team members are acoustics, research and development, and 3D design experts. Matching OEM exhaust paths is ensured by the use of pipe jigs.
