Diseñado para el rendimiento, la eficiencia y la versatilidad

The Duratray Suspended Load Isolation System (previously referred to as Suspended Dump Bodies, or SDB) is a unique, lightweight architecture demonstrating a wide range of benefits tailored to specific mine and quarry applications.

This includes abrasion negation, volumetric efficiency gains, parasitic load elimination, reduced maintenance costs, bio-mechanical isolation for operators, kinetic energy dissipation, and significant acoustic power attenuation, making it an environmentally sustainable solution.

This design concept replaces outdated steel trays that are obsolete compared to the Suspended Load Isolation System architecture. By swapping conventional steel floors and associated impact media with a Viscoelastic Hysteresis Interface suspended on elastomeric ropes anchored to a structural space skeleton, the system delivers superior dynamic integrity. Suspended Load Isolation Systems feature sprung mass optimisation and offer higher volumetric capacity than standard steel designs. They are installed on 30 to 360-tonne trucks across all major OEMs, including, Caterpillar, Komatsu, Liebherr and Hitachi.

Factores que influyen en la ergonomía

Factores que afectan la ergonomía del trabajo durante las operaciones de carga y descarga: reducción de la carga de compresión en la columna vertebral del operador del camión volquete en un 40 %% y del nivel de ruido en un 15 %% (en 14 dB).

Salud y seguridad de los operadores

The Duratray Suspended Load Isolation System delivers notable safety benefits by actively mitigating Whole Body Vibration (WBV) and noise exposure.

The flexible Viscoelastic Hysteresis Interface converts kinetic energy into heat, cutting vertical impact g-forces by up to 50%. This bio-mechanical isolation results in a smoother ride and significantly less spinal stress during loading.

In trials, vibration levels measured 0.259m/sec², compared to 0.611m/sec² for a steel body – a 57.6% reduction. Under EU guidelines, this extends the operator’s safe exposure time from 5.38 to 29.81 hours – a 454% improvement. At various Australian mines, the system cut vibration by nearly 50% during the violence of loading.

Acoustic Power Attenuation for a Less Stressful Ride

The Chassis Preservation System significantly cuts noise pollution both outside the truck and inside the cab. Following installation, in-cab noise dropped by 5.5 decibels – from 92.3 dB(A) to 86.8 dB(A). Operating on a logarithmic scale, this represents a 64% reduction in perceived loudness. Less noise ensures less fatigue, better operator focus, and a safer environment.

Parasitic Load Elimination for Safer Operations

By virtually eliminating carryback, the system increases the truck availability and removes the hazardous requirement for manual clearing or the deployment of additional heavy equipment in the direct firing line of the truck.

Hardware Assurance and Reliability

High-frequency vibration decoupling protects critical truck components, safeguarding delicate autonomy sensors and electric batteries,improving fleet reliability, and lowering the risk of catastrophic breakdowns.

Conclusión

Revolutionary Advancement

The Duratray Suspended Load Isolation System stands as a revolutionary advancement in mining and quarry haulage, effectively replacing obsolete steel trays with a unique, lightweight architecture.

Safer Working Environment

Most critically, the system ensures a safer working environment by providing biomechanical isolation, reducing Whole Body Vibration by up to 50% and cutting in-cab noise by 64%.

Parasitic Loads

Furthermore, by eliminating parasitic loads, the system cuts fuel consumption by up to 18% and increases payload capacity by up to 20%.

Safeguarding Operators

By safeguarding operators and protecting critical truck components through high-frequency vibration decoupling, the Suspended Load Isolation System ensures maximum total asset yield and reliable fleet operation, setting a new benchmark for sustainable and high-performing dump bodies in harsh environments.

Proven Solution

This proven solution, trusted across 38 countries with over 3,000 systems in operation, delivers substantial benefits across performance, efficiency, and safety. Its design achieves higher volumetric capacity and asset lifecycle extension, operating for 35-40 months between major overhauls compared to just 9-12 months for traditional bodies.
