Mining & Quarry
Heavy-duty decks built for dust, vibration, and overload conditions.
01What we hear from this industry
- Standard decks fail early under quarry loading
- Remote sites need weighbridges that survive rough handling
- High-tonnage trucks need 80–120T capacity, not standard ranges
02How weighing actually works here
The deck is an outdoor structure first, a scale second
A weighbridge at a mine or quarry sits at the end of a haul road, taking a continuous stream of loaded dump trucks and tippers whose axle loads, tyre pressure, and approach speed are far rougher on a deck than typical highway traffic. Before it's a precision instrument, it's a structural component that has to survive dust settling into every gap, vibration from nearby blasting or crushing operations, and the routine possibility of a truck arriving overloaded rather than exactly at its rated capacity. Deck and load cell selection here starts from that environment, not from the weighing tolerance alone.
Capacity headroom, not just capacity match
Haul trucks and tippers at extraction sites commonly run in the 80–120 tonne gross weight range, well above a standard commercial weighbridge's typical rating, and site operators frequently overload rather than under-load, since the cost of an extra haul cycle is real money. Specifying a deck and load cells rated with genuine headroom above the heaviest vehicle expected — not just matched to it — is standard practice here, because a deck running near its rated limit on every single crossing degrades faster and gives less warning before something fails.
Foundation choice follows the site, not a default
Extraction sites are frequently temporary or shifting — a quarry face moves, a mine's active pit relocates, a project has a defined multi-year life rather than being a permanent facility. That's why foundation-less and composite (steel-plus-concrete) decks show up so often in this industry: foundation-less for weighing points that may need to move with the operation, and composite where the deck needs to stay in one place but the dust, moisture, and abrasive material handled at the site would chew through a bare steel running surface faster than it would a concrete one.
03Problems it solves
Decks specified for road traffic fail early under quarry loading
A weighbridge built to a general commercial-vehicle standard, dropped into a quarry environment with heavier axle loads, more vibration, and near-constant dust and grit ingress, tends to show structural fatigue and load cell drift well ahead of its expected service life. Specifying for the actual site conditions from the start — not a generic default — is what avoids an early, expensive deck replacement.
Remote sites can't count on a quick service call
A mine or quarry is often a considerable distance from the nearest town, let alone a service technician, so equipment that needs frequent field adjustment or is easily knocked out of calibration by rough handling creates real downtime risk. Rugged construction and load cells with genuine environmental sealing reduce how often a remote site needs to call someone out at all.
Standard capacity ranges undersell what the trucks actually weigh
A weighbridge rated for a typical 40–60 tonne commercial vehicle simply can't handle the loaded weight of a large haul truck or articulated tipper common at extraction sites, and running such vehicles across an undersized deck either produces an unreliable reading or risks damaging the structure. Matching deck and load cell capacity to 80–120 tonne-class vehicles, with margin, is a baseline requirement here rather than an upgrade.
04Why it matters
Extraction operations are billed and taxed on tonnage extracted or hauled, so a weighbridge here isn't just an operational convenience — it's frequently the instrument behind royalty payments, contractor settlements, and regulatory reporting. A deck that fails early or drifts out of calibration under the specific abuse a quarry environment delivers doesn't just cost a replacement — it puts every tonnage figure calculated in the meantime in question. Building for dust, vibration, and genuine overload conditions from day one, with capacity headroom rather than a tight match, is what keeps a remote, high-tonnage site's numbers defensible and its haul road moving without an unplanned deck outage in the middle of a production run.
05Recommended equipment
Pit Type (In-Ground) Weighbridge
In-ground weighbridge for sites where space is constrained — deck sits flush with the ground, no ramps needed.
Foundation-less Weighbridge
Fully portable weighbridge that relocates in hours — needs only a hard, level ground base, no foundation work.
Composite Weighbridge (RCC + Steel)
Heavy-duty steel and concrete weighbridge, installable as pit-type or pitless — built for corrosive or high-wear environments.
Junction Box
Stainless-steel junction boxes for 4 to 10 load cells, IP65-rated with digital trim and inbuilt surge protection per channel.

07Frequently asked
What capacity range do we actually need for our haul trucks?
Size the weighbridge to your heaviest loaded vehicle plus a genuine safety margin — extraction-site trucks commonly run 80–120 tonnes gross, and given how often sites run vehicles at or above nominal capacity, headroom above the heaviest expected load is worth specifying rather than an exact match.
Will a standard weighbridge deck survive constant dust and vibration?
A deck and load cells specified for general commercial traffic often won't hold up as well as one built for quarry conditions specifically — sealed, environmentally rated load cells and a structurally heavier-duty deck are the difference, and it's worth confirming those ratings rather than assuming a standard product will cope.
Should we choose a pit-type or a composite deck for a quarry?
Pit-type suits a fixed, permanent weighing point; a composite steel-and-concrete deck is often preferred at sites handling abrasive or corrosive material, since concrete resurfaces more easily than replacing worn steel plate — the right choice depends on whether your site is permanent and what material is crossing the deck.
How often does equipment need servicing given how remote our site is?
Ruggedized construction and sealed load cells are chosen specifically to stretch the interval between required service visits at remote sites, but periodic calibration checks (commonly annual, or per local requirements) still apply regardless of location — plan service visits around that schedule rather than waiting for a fault to appear.
Can the deck be relocated if our extraction site moves or closes?
A foundation-less weighbridge is built specifically for that scenario — it can be relocated to a new site within hours of the new ground being prepared, without the fixed foundation a pit-type or standard modular bridge requires.
