Produk / Ruang Lingkup – Turn-key M-STEALTH™ Package on the Komatsu 930E-5 haul truck
Ringkasan
The client required a robust sound attenuation solution to meet stringent asset-level noise requirements for their Komatsu 930E-5 haul truck fleet. The goal was to reduce the cumulative sound power generated by surface operations while minimizing emissions, without compromising performance or payload.
Tantangan
The mine operates under strict environmental regulations and risks exceeding regulated site noise limits without a long-term noise control solution in place for nearby receptors and ongoing monitoring. Therefore, a site-wide compliance strategy was necessary to avoid community impact and operational restrictions.
Cakupan
Minetek Sound was engaged to attenuate six Komatsu 930E-5 haul trucks with a custom solution that:
- Mencapai target daya suara spesifik lokasi
- Menggunakan komponen minimal untuk menjaga efisiensi muatan
- Mempertahankan toleransi tekanan balik dan aliran udara OEM yang ketat
Minetek engineers modified the M-STEALTH™ Sound Package to accommodate new undercarriage variations, demonstrating the flexibility and precision of the design process.
Hasil
- Noise reduction: From 120 dBA to 115 dBA
- Compliance: Machines can now operate 450m closer to site boundaries
- Efficiency: All 6 trucks completed on schedule with no safety issues
- Preservation: Payload retained through lightweight component selection
Minetek delivered a compliant, high-performance attenuation solution tailored to the client's operational needs. The project achieved regulatory compliance without downtime, risk, or payload loss. The M-STEALTH™ Sound Package enabled the fleet to meet regulatory requirements while maintaining productivity and supporting the mine’s social license to operate.
Pra atenuasi
120 dBA
The Komatsu 930E-5 registered a factory sound frequency level of 120 dBA prior to Minetek Sound Attenuation.
Pasca atenuasi
115 dBA
The sound output of the Komatsu 930E-5 was tested after installing Minetek’s turn-key M-STEALTH™ sound attention solution. This registered a sound frequency level of 115dBA.
Pengurangan suara
5 dBA
Minetek was able to reduce the sound output on the Komatsu 930E-5 mining haul truck by 5dBA.
