Weighbridge for Mining Sites in Nigeria: Remote and Rugged

Nigeria's solid minerals sector is growing, with coal in Enugu and Kogi, tin and columbite in Plateau, lead and zinc in Ebonyi and Nasarawa, limestone, gypsum, barite and many other minerals across the country. Each tonne extracted and sold needs to be weighed. A well-chosen weighbridge for mining sites in Nigeria gives operators accurate production figures, fair sales records and the documentation that buyers, partners and authorities expect.

Mining sites differ from quarries in an important way: they are often remote, with poor roads, limited power and sites that may move as the pit advances. This guide explains how to choose a weighbridge that copes with those conditions. For crushed stone operations, see our separate guide to the weighbridge for quarry in Nigeria.

Why Mines Need Accurate Weighing

Weighing underpins almost every part of a mining business:

• Sales. Ore and concentrate are sold by weight, often with grade adjustments. The weighbridge ticket is the basis of the invoice.
• Production records. Knowing how many tonnes leave the pit each day lets you track output and plan.
• Royalties and reporting. Records of tonnage help with reporting to the relevant authorities and partners.
• Contractor payments. Haulage and loading contractors are often paid per tonne moved.
• Theft and leakage. Valuable minerals are a target; weight records help detect missing loads.

Choosing a Weighbridge for Mining Sites in Nigeria

Capacity

Mining trucks range from 10-wheel tippers to articulated trailers carrying ore to processing plants or ports. Choose a capacity comfortably above your heaviest loaded truck:

• 60 to 80 tonnes for sites using rigid tippers. See the 80 tonne heavy-duty weighbridge.
• 100 to 120 tonnes where trailers are used. The 120 tonne heavy-duty weighbridge is a robust option.
• 150 tonnes for the heaviest traffic, using the 150 tonne extra-heavy weighbridge.

Deck length

The deck must hold the whole vehicle. Rigid tippers suit 12 m to 18 m decks; trailers need 18 m to 24 m.

Fixed or portable

If the site will operate for many years from one gate, a fixed surface-mounted or pit-type weighbridge is ideal. If the working face, haul road or loading point will move, consider a portable pitless weighbridge that can be relocated with a crane and a flat, compacted base. For spot checks between sites, portable axle weighing pads are also useful.

Ground, Drainage and Civil Works

Mining areas often have rocky, uneven or waterlogged ground. A weighbridge is only as good as its foundation:

• The foundation must be level and strong enough for repeated heavy loads.
• Drainage must carry rainwater and mud away from the deck and load cells.
• Approach slabs at both ends reduce shock from trucks driving on.

Kira's weighbridge civil works and foundation package covers this as part of the weighbridge installation, with designs suited to the soil on site.

Power, Lightning and Remote Operation

Many mines run on generators or have no grid supply at all. Plan for:

• A stable power supply for the indicator and PC, with inverter or solar backup so weights are not lost when the generator stops.
• A lightning and surge protection kit, as remote, elevated sites are exposed to storms.
• Sealed, heavy-duty load cells such as the 40/50 tonne compression column load cell, which handle dust and shock well.

Where management is based in Abuja, Lagos or abroad, weighbridge software with Excel reports and CCTV snapshots helps head office see what is being weighed on site.

Security at the Mine Gate

Valuable minerals attract theft and manipulation. Good controls include:

• Barriers and traffic lights so every truck must stop on the weighbridge.
• CCTV snapshots of each weighing, linked to the ticket.
• Numbered tickets that cannot be edited or deleted without a record.
• Regular checks comparing mine output, stockpiles and weighbridge totals.

Calibration and Maintenance in Remote Locations

A weighbridge used for sales must hold a valid Weights and Measures certificate of verification, renewed at least once a year. Because mine weighbridges work hard in tough conditions, many operators choose weighbridge calibration every three or six months.

Simple daily routines matter even more on remote sites: clear mud and stones from around the deck, keep drains open and check the zero reading at the start of each shift. If you notice drift, call for weighbridge repair early.

Planning Before You Order

A little planning saves time and cost on a remote site. Before requesting a quote, gather:

• The type, length and loaded weight of your heaviest trucks.
• Expected daily truck numbers, now and as production grows.
• Access conditions for delivering a long steel deck to site.
• Available power and the location for the weighbridge office.
• How long you expect to operate from the current loading point.

This information decides capacity, fixed or portable design and the scope of civil works.

Why Mining Operators Choose Kira Scales

Kira Scales has supplied and installed weighbridges since 2015, with more than 70 installations across Nigeria, including quarries and construction sites in demanding locations. We supply locally fabricated and imported decks, handle civil works and power protection, and provide certified calibration. Our teams travel to every state, including mining areas in Plateau, Enugu, Kogi, Nasarawa, Ebonyi, Niger and Zamfara.

Costs depend on capacity, deck length, fixed or portable design, ground conditions and accessories. See the product pages for current pricing or request a quote.
