Ports and container terminals move some of the heaviest and most valuable loads in the country. Every container that enters or leaves needs a reliable weight, for safety, for customs and shipping documents, and for billing. Choosing the right weighbridge for ports and container terminals Nigeria operators can depend on means planning for long trailers, heavy traffic and very little downtime.
Kira Scales has carried out weighbridge projects at Apapa port, in Port Harcourt and at container depots. This guide explains what port and terminal operators, inland container depots (ICDs), bonded warehouses and freight forwarders should consider.
Why Weighing Matters at Ports and Terminals
Weighing at a port or depot serves several purposes:
- Verified gross mass (VGM). International shipping rules require a verified gross mass for packed export containers before loading on a ship. A certified weighbridge is one of the accepted ways to obtain it.
- Safety. Misdeclared container weights put ships, cranes, trucks and roads at risk.
- Billing and documentation. Handling charges, storage and haulage are often linked to weight.
- Overload control. Trucks leaving the terminal should not exceed road limits.
Because weights from the port feed into legal and commercial documents, the weighbridge must be accurate, certified and well maintained.
Sizing a Weighbridge for Ports and Container Terminals in Nigeria
A loaded 40-foot container on an articulated trailer is a long, heavy vehicle. Most ports and depots choose:
- 100 to 120 tonnes capacity, giving comfortable headroom above typical container truck weights. See our 120 tonne heavy-duty weighbridge.
- 150 tonnes for the heaviest project cargo and abnormal loads. The 150 tonne extra-heavy weighbridge was specified for ports and quarries.
- A deck of 21 m to 24 m, long enough to weigh the whole truck and trailer in one go.
Single-pass weighing on a full-length deck is more accurate and faster than weighing axle by axle. For enforcement lanes or quick axle checks, an in-motion axle weighbridge can complement the main scale.
Pit-Type or Surface-Mounted in a Port Yard?
Port yards are busy and space is often tight.
- Pit-type weighbridges sit flush with the yard, so trucks and reach stackers can cross from any direction. The 100 tonne pit-type weighbridge is a common choice. Coastal areas like Lagos and Port Harcourt have high water tables, so pit drainage must be designed carefully.
- Surface-mounted weighbridges avoid pit flooding and are quicker to build, but need space for ramps at both ends.
Kira handles the full weighbridge installation, including civil works designed for soft coastal soils and heavy rainfall.
Handling Heavy Traffic: Automation and Throughput
At busy terminals, queues at the weighbridge cost money. Automation helps:
- An unmanned weighbridge automation package with ANPR cameras, RFID tags and barriers lets trucks weigh without an operator keying in details.
- A weighbridge CCTV camera kit captures snapshots of each vehicle and container number with the weight, which is useful when weights are disputed.
- Traffic lights and boom barriers control entry so only one vehicle is on the deck at a time.
- Weighbridge software records container numbers, seal numbers, shipping line and customer, and exports data to your terminal or billing system.
Our article on unmanned weighbridge automation covers these options in more detail.
Durability in a Coastal Environment
Salt air, humidity and heavy rain are hard on steel and electronics. For port weighbridges we recommend:
- Proper surface preparation and protective coating on steel decks.
- Sealed, stainless or nickel-plated load cells such as the QS-A 30 tonne shear beam load cell.
- Sealed junction boxes and protected cable routes.
- Lightning and surge protection, as port areas are open and exposed.
Regular inspection catches corrosion and cable damage before they affect accuracy.
Certification and Calibration for Port Weighbridges
Weights used for VGM, billing and trade must come from a weighbridge with a valid Weights and Measures certificate of verification, renewed at least once a year. Given the traffic and the consequences of errors, many terminals choose weighbridge calibration every three or six months.
Kira holds a Certificate of Pattern Approval from the Weights and Measures Department for its weighbridge and provides certified calibration nationwide.
Repairs and Upgrades for Existing Port Scales
Many terminals already have weighbridges, some of them older Avery or imported systems. Rather than replace everything, Kira can upgrade the load cells, indicator and software, or carry out weighbridge repair on any brand. A weighbridge digital upgrade kit can bring an older scale up to date with less downtime.
Planning a Port Weighbridge Project
Port projects involve more stakeholders than most. Before work starts, agree:
- Where trucks queue, so the weighbridge does not block terminal traffic.
- How weights will be shared with shipping lines, customs agents and customers.
- A schedule for civil works that keeps at least one weighing lane open.
Why Port Operators Work With Kira Scales
Kira Scales has worked in Nigerian weighing since 2015, with more than 70 weighbridge installations, including projects at Apapa, Port Harcourt and container depots. We supply locally fabricated and imported decks, carry out civil works, integrate automation and provide certified calibration, with teams that travel to every state. That includes the ports and depots of Lagos, Rivers, Delta, Ogun and the inland dry ports.
Costs depend on capacity, deck length, pit or surface design, automation and site conditions. See the product pages for current pricing or request a quote. See also our weighbridge services in Port Harcourt.

Frequently Asked Questions
Can a weighbridge be used for container VGM in Nigeria?
Yes. A certified weighbridge with a valid Weights and Measures certificate of verification can be used to weigh the packed container and truck, with the vehicle tare deducted to obtain the gross mass.
What capacity weighbridge do container terminals need?
Most terminals use 100 to 120 tonnes on a 21 m to 24 m deck. Sites handling heavy project cargo may choose 150 tonnes.
Is a pit weighbridge suitable for a port area with a high water table?
It can be, but the pit needs careful drainage design. Surface-mounted weighbridges avoid pit flooding and are often preferred on low-lying coastal sites.
Can the weighbridge record container numbers automatically?
Yes. ANPR cameras, CCTV snapshots and software can record vehicle and container details with each weight.
Can you upgrade an old weighbridge at our depot?
Yes. Kira upgrades and repairs weighbridges of any brand, including replacing load cells, indicators and software.
