A 100 ton weighbridge is a truck scale designed for vehicles whose maximum gross weight can reach approximately 100 metric tonnes. Before buying, confirm that the scale’s rated capacity, platform length and width, foundation, and weighing system match the vehicles and operating conditions at your site. A 100-tonne rating equals 100,000 kg, but capacity alone does not determine whether a weighbridge will handle your heaviest vehicle safely and effectively. In this guide, we explain how to assess the application, compare configurations, prepare a purchasing specification, and evaluate supplier support.

This guide is for procurement teams, plant managers, logistics operators, and project engineers sourcing a weighbridge for industrial or commercial vehicle weighing. It is relevant to facilities that receive or dispatch bulk materials, manage heavy transport fleets, or need documented weight records for operational control. Buyers planning a new installation can use it to define project requirements before requesting a quotation. Existing weighbridge operators can also use the checklist when replacing or upgrading equipment.
A weighbridge measures the weight of a truck and its load as the vehicle drives onto a platform. In a typical electronic system, load cells detect the force applied to the platform and send signals to an indicator or connected weighing software. Depending on the configuration, the system can record a gross weight, a tare weight, and a calculated net weight. The complete installation may also include a foundation, access ramps, a weighing indicator, a printer, and data connections.
The rated capacity is a design specification, not a guarantee that every site or vehicle will be suitable. Buyers should distinguish the scale’s maximum capacity from the actual gross and axle loads of vehicles expected at the facility. They should also establish whether weighing will take place with the whole vehicle on the platform or in separate axle or section readings. These operating details influence platform design, installation planning, and the way results are used.
Steel-deck weighbridges use a structural steel platform and may suit projects where modular sections, transport, or installation constraints are important. Concrete-deck designs use concrete as the weighing surface, typically supported by a structural system specified for the project. Material choice affects the platform design, installation work, maintenance planning, and site logistics; neither option is universally better. Ask suppliers to explain the trade-offs for your traffic, climate, foundation, and maintenance resources.
A pit-mounted weighbridge sits within a prepared recess, while an above-ground installation uses ramps to guide vehicles onto the platform. A pit may be considered where space around the scale is limited, but drainage, access for inspection, and construction requirements need careful planning. An above-ground arrangement may simplify access to some components, but it requires sufficient approach and exit space. Confirm site levels, vehicle turning paths, drainage, and service access before deciding.
The weighing system can be configured with an indicator and, where required, additional equipment for printing or transferring records. Buyers should identify whether operators need manual entry, truck identification, transaction records, or integration with an existing management system. Check which interfaces and software functions are included in the offer rather than assuming they come standard. Also clarify data ownership, backup procedures, user permissions, and the process for diagnosing faults.
Start with the vehicles, not a catalogue description. List the truck types, their overall lengths, wheel arrangements, maximum gross weights, and expected axle loads. Then identify whether vehicles will cross the scale straight through, stop for a static weighing, or be weighed using a different operating procedure. This information helps determine the usable platform dimensions and the weighing workflow.
Consider the site and operating environment as well. Record available space, ground conditions, expected vehicle frequency, exposure to weather or corrosive materials, and access for construction equipment. If a weighbridge will support commercial transactions or regulated activities, confirm the applicable local requirements for approval, verification, and display increments with the relevant authority. These obligations vary by location and intended use, so they should be confirmed before purchase.
Compare the proposed rating with the heaviest expected vehicle and load, including the way the vehicle will be positioned during weighing. Consider axle loading and traffic patterns, not only the truck’s advertised gross weight. Ask the supplier to explain how the proposed capacity relates to the intended use and the design of the platform and supporting structure. If your fleet or loads may change, share that possibility during specification rather than relying on an assumed capacity margin.

Provide vehicle measurements and a site plan so the supplier can recommend a platform layout for review. The foundation design should be coordinated with site conditions, drainage, access, and the selected installation type. Clarify which party is responsible for civil engineering, excavation, concrete work, electrical supply, and installation supervision. A written division of responsibilities helps prevent scope gaps between the equipment order and site construction.
Specify how operators identify vehicles, capture transactions, print tickets, and share weight data. Explain whether the system needs to connect with existing business software or operate as a standalone weighing station. Ask for a list of included hardware, software functions, communication interfaces, and any optional items. For a B2B site, the practical value of automation depends on how well the system fits the existing process and the skills of the people who will use it.
Request technical drawings, installation requirements, operating instructions, maintenance guidance, and the documents applicable to your market and use case. Confirm what commissioning, operator training, warranty coverage, and after-sales assistance the supplier offers. Ask how spare parts are identified and ordered, and how technical support is provided if the system reports an error. Get these details in writing so your team can compare offers on scope as well as price.
The total project cost depends on more than the weighbridge platform. Configuration, deck material, dimensions, electronic equipment, installation scope, foundation work, shipping, and local compliance requirements can all affect the quotation. A supplier quote should state what is included and identify exclusions such as civil works, site preparation, electrical installation, taxes, or local verification. Request an itemized offer so you can compare suppliers on equivalent requirements.
Minimum order quantities and production lead times depend on the supplier’s product configuration and project schedule. Rather than relying on a general estimate, ask for a confirmed timeline covering drawing approval, manufacturing, dispatch, installation, and commissioning where applicable. Provide your required delivery location and target date when requesting an offer. This allows the supplier to assess transport and project constraints before confirming a schedule.
For a fair comparison, send each supplier the same vehicle details, site information, operating requirements, and delivery expectations. A low initial price may not represent the complete project cost if important components or services are excluded. Review technical fit, scope clarity, documentation, and support alongside the commercial offer. Where requirements are uncertain, ask the supplier to identify assumptions and open points rather than treating them as settled specifications.
One common mistake is selecting a scale based only on its 100-tonne rating without checking platform dimensions and axle-loading conditions. Another is postponing foundation and drainage planning until after equipment selection, which can create avoidable coordination problems. Buyers may also assume that software, printers, installation, or verification are included when they are not listed in the quotation. Resolve these questions during specification and document the answers before placing an order.
It is also important not to treat legal metrology requirements as universal. The rules can depend on where the weighbridge is installed and whether weights are used for commercial transactions or other regulated purposes. Confirm the applicable requirements with local authorities or qualified professionals, and ask the supplier to identify the documents and equipment provisions relevant to the project. This helps ensure that technical planning and regulatory checks proceed together.
A 100 ton weighbridge can be a suitable choice when its rating, platform, foundation, electronic system, and support package match the vehicles and work carried out at your site. Before requesting a final quotation, document your maximum vehicle and axle loads, vehicle dimensions, weighing workflow, site conditions, data needs, and local compliance requirements. Then compare itemized proposals and confirm responsibilities, lead time, and after-sales provisions in writing. Wanji can discuss your project requirements and help you identify the information needed to evaluate a suitable weighbridge configuration and request a quotation.
