Rocktec designed, built, installed, and commissioned a fully automated wheel and underbody wash system for Stevenson Resources Ltd at their Drury Quarry site in New Zealand. With high volumes of heavy vehicles entering and leaving the site daily, this system was developed to ensure environmental compliance, minimise debris on public roads, and maintain operational efficiency.
Project Overview: Automated Vehicle Wash for Drury Quarry
- Client: Stevenson Resources Ltd
- Location: Drury, New Zealand
- Industry: Quarrying / Environmental Compliance
- Scope: Design and build of a fully automated wheel and underbody wash for heavy-duty quarry vehicles
The Challenge: High-Traffic Quarry Requiring Effective Debris Removal
Drury Quarry is one of New Zealand’s largest and most advanced aggregate production sites, supplying over a quarter of Auckland’s aggregate demand. With millions of tonnes processed annually and constant truck movement, the site needed a drive-through wash system that could remove mud and debris quickly and consistently—without slowing down operations.
Rocktec’s Solution: Fully Automatic Wheel and Underbody Wash System
Rocktec delivered a smart and rugged solution designed to handle continuous use in a demanding quarry environment:
- 4-metre wash length to accommodate long wheelbases and undercarriages
- 84 high-pressure jets arranged to cover tyres and underbodies from all angles
- Sensor-triggered automation allowing vehicles to drive through without stopping
- Side spray bars with adjustable angles for better edge coverage
- Overspray containment screens installed to minimise water loss and site mess
- Compatible with all road-going vehicle types, including trucks and heavy quarry haulers
This fully enclosed system provides consistent cleaning results while maintaining safe and clean road conditions beyond the quarry.
Installation and Performance
- Design: Rocktec engineered the system to fit within existing traffic lanes and vehicle flow paths at the Drury site.
- Fabrication: Components were pre-built off-site for quick assembly and quality control.
- Installation: The wash system was installed with minimal disruption to regular quarry operations.
- Commissioning: Final testing confirmed sensor accuracy, jet performance, and full wash coverage across all vehicle types.
Results and Benefits
- Environmental Compliance: Reduces track-out and road pollution near the quarry.
- Fully Automated: Sensor-triggered operation eliminates the need for drivers to stop or engage the system manually.
- Thorough Cleaning: 84 precision-aligned jets clean wheels and underbodies with high pressure and full coverage.
- Efficient Throughput: The drive-through system keeps vehicle flow steady and avoids operational delays.
Conclusion: Reliable Vehicle Cleaning at Scale
This wheel and underbody wash system highlights Rocktec’s ability to engineer efficient, durable, and environmentally responsible solutions for high-traffic industrial sites. At Drury Quarry, the system supports site cleanliness, safety, and long-term regulatory compliance.
