Six Wheeler 4WD Vehicle Conversions for Mining Fleets
Six Wheeler Conversions converts modern four-wheel drive (4WD) utes to increase gross vehicle mass (GVM) and towing capacities.
We aim to resolve load carrying and towing issues in both on and off-road mining and fleet vehicles.
High-performance four-wheel drive vehicles for the mining sector
Two major benefits of a Six Wheeler conversion is increased towing capacity and payload levels, making them popular for vehicles carrying heavy loads and /or towing.
Other benefits include:
- Increased payloads: up to two tonnes (t)
- Improved GVM’s: up to 4,495kg on a car licence, or higher on a light truck licence
- Longer trays: up to 3.6m on single cabs
- More stability on and off road, resulting in decreased body roll
- Enhanced towing capacity: up to 4,500kg
- Upgraded safety with superior braking ability with the braked rear axle
- Better off-road ability in comparison to a fully loaded 4×4
- Improved ride and comfort
For many years, the caravanning industry has provided a larger share of the revenue pool. However, with a growing GVM and compliance issue across numerous industries, Six Wheeler is now providing an affordable and versatile solution for many sectors to meet their workplace health safety (WHS) and transport department compliance requirements, along with an increased tray length and a safer, smoother ride.
Second-stage manufacturing approvals (SSMs) mean that our vehicles are federally compliant, allowing us to increase original equipment manufacturer (OEM) GVM and tow ratings. All designs are engineered, tested and certified to suit each vehicle.
Vehicle conversions for industrial, heavy-duty applications
Six Wheeler’s conversions provide a suitable platform for fleet, mining and service vehicles.
A typical conversion will see the GVM of most vehicles increased to 4,495kg so the end user retains a car licence, but higher heavy-vehicle GVM variants are possible. Land Cruiser VDJ series utes can have a GVM up to 5,495kg and a towing capacity increase up to 4,500kg with a gross combination mass (GCM) of 8,995kg. These are available with custom trays ranging from 2.6m to 3.5m, which increase vehicle functionality for extended work away from main hubs.
Many different brands have been converted over the years, but Six Wheeler has four current models with SSM approval. These include the Ford Ranger, Mazda BT-50, Isuzu D-Max, and the Toyota Land Cruiser 79 series in both single and dual cab variants.
Under separate approvals, we have also converted Holden Colorados, Nissan Navaras, Toyota Hiluxes and Ford F250s, and currently have a VW Amarok conversion that is almost ready for testing.
The foundation of our conversions is a 6×4 lazy axle set-up. The host vehicle is largely untouched, but we add the braked, rear lazy axle and new leaf spring suspension. This system has been refined on several very heavy load carrying vehicles and typically gives a 60:40 load share between the drive wheels and the lazy axle to achieve high-performance articulation.
Ute trays and vehicle accessories
Six Wheeler distributes and manufactures a range of accessories to complement our products, including the patented Eye-Tie ute tray.
Capable of carrying up to 2.5t, these hybrid steel and alloy trays allow any load to be securely tied down within the tray from an array of internal ‘Eye-Tie’ points.
Our team has also recently released the ‘SupaTub’, a 2.4m style-side ute ‘tub’, which suits the Rangers and current BT-50s, along with chassis strengthening kits.
