Heavy duty · up to approx. 80 t
Mining mud is a structural problem and a sludge problem.
Same 2200 × 3000 mm module footprint, substantially reinforced load-bearing structure — and a collection and sludge-handling arrangement designed for the volume of solids heavy equipment actually brings onto the pad.
The engineering
Gross weight is the easy part
An 80-tonne class rack is not a medium-duty rack with thicker plate. The design has to account for how that mass actually arrives on the deck — concentrated, repeatedly, and moving.
- Individual axle load and individual wheel load, not just gross vehicle weight
- Tyre contact area — the same axle load through a different tyre is a different pressure
- Track loading for tracked equipment, which concentrates load quite differently
- Concentrated point loads, including outriggers and jacking points
- Dynamic loading as a machine drives on and off the rack
- Repeated loading and fatigue over the life of the installation
The 80-tonne classification is a product design target. Final published axle, wheel and point-load capacities are based on structural calculation and validation before they are stated as guaranteed specifications — so send us the machine list and we will confirm what your fleet needs.
One thing we will not do is imply that every heavy-duty configuration takes every mining haul truck. The largest haul trucks are a different conversation, and it starts with vehicle dimensions and individual wheel and axle loads.
What it carries
Vehicles in the heavy-duty class
Indicative vehicle class: up to approximately 80 tonnes, confirmed per machine.
Mining support equipment
Service trucks, water trucks, graders and support fleet.
Large wheel loaders and dozers
Production loaders and tracked dozers.
Heavy construction machinery
Large excavators and heavy earthmoving plant.
Heavy haulage and off-road trucks
Large off-road trucks and heavy transport equipment.
Armoured and engineering vehicles
Heavy military and special-purpose engineering vehicles.
Tracked equipment
Track loading assessed separately from wheel loading.
Solids
This is where a scraper conveyor earns its keep
Heavy equipment brings soil, clay, mining fines and rock onto the pad in quantity. Collected water off a mine vehicle is not car-wash effluent, and treating it as if it were is how treatment plants get blocked.
- A scraper conveyor removes accumulated heavy solids and sludge from the collection area mechanically
- A sludge-capable pump transfers dirty water and slurry toward the treatment equipment
- Solids separation ahead of the plant, so filtration is doing filtration rather than desilting
- The exact arrangement follows the anticipated solids loading — it is specified, not assumed

| Assembly | Bolted, relocatable |
| Ramps | Entry / exit, load-matched, gradient to suit the equipment |
| Splash guards | Optional — single-side or three-sided |
| Sludge pump | Recommended |
| Scraper conveyor | Recommended for high mud loads |
| Containerised water recycling | Recommended |
The other return
A clean machine is a machine you can actually inspect
Washing heavy equipment is not housekeeping. On a mine or a large earthworks site it is part of maintenance and part of risk control.
- Accumulated debris and oily build-up around hot surfaces is a recognised equipment fire risk
- You cannot see a weeping hydraulic line, a chafing hose or a cracked weld through a coat of clay
- Rock and packed material in the undercarriage accelerates wear on components that are expensive to replace
- Machines washed before they go into the workshop cut the time a fitter spends cleaning instead of fixing
- Soil moved between sites on an undercarriage is exactly what washdown and biosecurity controls exist to prevent
Send us the fleet and the mud
Machine list with axle and wheel loads where you have them, the soil you are dealing with, and your wash volumes. Our engineers will come back with a structural class, a pad layout and a sludge and treatment arrangement.
