100 Ton Weighbridge Buying Guide: Capacity, Platform Size, Installation, and System Configuration
A 100 ton weighbridge is a truck scale designed with a stated maximum weighing capacity of 100 metric tonnes. To choose the right system, I recommend checking more than the capacity: confirm the heaviest vehicle and axle loads, select a platform that suits the longest trucks, assess the site and foundation, and specify the weighing and data-management equipment. The right configuration depends on how vehicles enter, cross, and leave the scale, as well as how weighing records will be used.

This guide is for procurement teams, plant managers, logistics operators, and project engineers comparing weighbridge options for a new installation or replacement. At Wanji, we help buyers define the scale and Electronic Data Systems requirements together, so the equipment fits both the site and the intended workflow. Final dimensions, foundation details, and system functions should be confirmed against the project conditions and applicable local requirements.
Key Takeaways
- Capacity: Treat 100 tonnes as the scale’s rated maximum, then check vehicle gross weights, axle loads, and expected traffic patterns with the supplier.
- Platform size: Choose the deck length and width based on the longest vehicles and how consistently drivers can position them.
- Installation: Site access, ground conditions, drainage, foundation design, and maintenance access all affect the installation plan.
- System configuration: Match the indicator, software, peripherals, and data connections to the actual weighing and reporting process.
- Procurement: Compare complete scope, including civil works responsibility, commissioning, documentation, and after-sales support.
What a 100 Ton Weighbridge Does
A weighbridge measures the weight of a vehicle positioned on its platform and sends the load-cell signals to a weighing indicator or connected system. Depending on the operating process, a site may record a loaded vehicle, an empty vehicle, or both to calculate the weight of goods carried. The weighbridge is therefore one part of a broader weighing workflow that can include driver instructions, vehicle identification, transaction records, and reporting.
The 100-ton rating does not by itself establish that every vehicle can be weighed safely or accurately in every operating condition. Buyers should discuss the maximum gross vehicle weight, axle configuration, wheel loads, approach conditions, and frequency of use with the supplier. They should also confirm whether the intended use requires legal-for-trade approval and what local metrology rules apply.
Choose Capacity and Platform Size Together
Confirm the real load profile
Start by listing the vehicle types that will use the scale, including their maximum loaded weights and axle arrangements. Consider occasional exceptional loads separately from routine traffic, and explain how often each type is expected to arrive. This gives the supplier a clearer basis for checking the scale configuration instead of relying on the capacity figure alone.
Ask how the proposed design handles concentrated wheel and axle loads, not only the total vehicle weight. The allowable operating conditions depend on the scale design and installation, so avoid assuming that a nominal 100-ton capacity resolves every loading question. Request written confirmation of the relevant design limits and operating guidance for your application.
Size the deck for vehicles and site layout
Platform length should allow the longest vehicle in your operation to be positioned fully on the weighing surface, while platform width should suit vehicle dimensions and the site’s alignment conditions. As an illustrative planning reference rather than a universal specification, buyers may compare configurations around 3 m wide and 16–18 m long. The appropriate dimensions must be confirmed against the actual fleet, local requirements, and available land.
Also map the approach and exit routes. A long deck can still be a poor fit if vehicles cannot line up safely or if turning space, gates, or nearby structures constrain movement. Share a site plan and representative vehicle dimensions with the supplier before requesting a final quotation.
Compare Platform Types and Materials
Weighbridges are commonly offered in pit-mounted and surface-mounted arrangements. A pit-mounted scale can provide a level crossing surface, but it requires suitable excavation, drainage, and access for inspection. A surface-mounted arrangement avoids a full weighing pit but uses ramps, which need to be considered in traffic planning and available site length.
Platform construction may use steel or concrete, with the best choice depending on the operating environment, project design, installation plan, and maintenance preferences. Steel platforms may be considered where modular sections and transport or installation constraints matter; concrete designs may suit projects with different structural and site priorities. Ask suppliers to explain the proposed construction, corrosion protection or finishing approach, maintenance access, and what is included in the delivered scope.
Plan the Installation Before Ordering
Check civil and site conditions
Before finalizing the purchase, assess ground conditions, drainage, vehicle access, utilities, and the position of the control room or operator station. Foundation design should be based on the scale drawings, site conditions, and applicable engineering requirements rather than a generic layout. Clarify who is responsible for civil design, construction, inspection, and any local approvals.

Drainage deserves particular attention for pit installations because standing water can interfere with access and maintenance. Surface-mounted scales also require a suitable base and approach ramps designed for the site’s traffic. Ask for installation drawings, foundation loads, service clearances, and interface requirements early enough to coordinate them with the civil contractor.
Agree on commissioning and operating checks
Define the commissioning scope before shipment, including installation supervision, indicator setup, functional checks, and operator instruction where applicable. Confirm which party provides any weights, vehicles, or other resources needed for site acceptance and calibration activities. If the scale is used for regulated trade, verify the approval and inspection process with the relevant local authority or qualified service provider.
Configure the Weighing and Data System
A basic system typically includes the platform, load cells, junction or signal connections, a weighing indicator, and a display or operator interface. Depending on the workflow, buyers may also request ticket printing, vehicle identification, traffic lights, barrier control, camera integration, or weighing software. These are configuration choices, not automatic features of every 100-ton weighbridge.
Describe the transaction from vehicle arrival to departure: who enters vehicle details, how tare and gross weights are captured, who approves exceptions, and what reports are required. For Electronic Data Systems integration, specify the data fields, user access, export or interface needs, backup expectations, and connection to existing business software. Wanji can discuss the weighbridge and system scope together, while final compatibility should be confirmed against the buyer’s network and software environment.
Use a Practical Selection Framework
- Document vehicle requirements. Provide maximum gross weights, axle layouts, vehicle lengths, and expected traffic patterns.
- Confirm dimensions. Match deck length and width to the fleet, driver positioning, and available site footprint.
- Select the installation type. Compare pit and surface-mounted options with attention to drainage, ramps, access, and maintenance.
- Define data functions. List required indicators, tickets, identification methods, reports, and system connections.
- Request a complete scope. Separate equipment, transport, civil works, installation, commissioning, training, and ongoing support.
- Review compliance needs. Confirm local weighing rules, approvals, and inspection responsibilities before purchase.
Pricing, Lead Time, and Supplier Evaluation
The price of a 100-ton weighbridge depends on factors such as platform dimensions, construction, load-cell and indicator configuration, software, transport, site work, and installation scope. A quotation that excludes foundations or commissioning may not be directly comparable with a more complete proposal. Ask each supplier to identify included and excluded items and state the assumptions used for the offer.
Lead time can vary with configuration, production scheduling, shipping arrangements, and site readiness. Rather than relying on a general estimate, request a project-specific schedule covering drawing approval, manufacturing, dispatch, installation, and commissioning. Also ask about spare parts availability, technical support channels, documentation, warranty terms, and the supplier’s process for handling service requests.
Supplier checklist
- Can the supplier explain how capacity and axle-load requirements were assessed?
- Are platform dimensions, materials, and installation drawings clearly stated?
- Does the quotation define the weighing indicator, software, peripherals, and interfaces?
- Are civil works, commissioning, training, and compliance responsibilities identified?
- Can the supplier describe after-sales support and provide relevant technical documentation?
Common Buying Mistakes to Avoid
One frequent mistake is choosing a platform based only on rated capacity while overlooking vehicle length, axle loads, or access geometry. Another is selecting a pit or ramp arrangement before checking drainage, foundations, and traffic flow. Buyers can also underestimate system requirements by treating software, ticketing, and data integration as minor add-ons rather than defining them in the original scope.
To reduce these risks, send suppliers the same vehicle data, site information, and system requirements. Compare proposals against a shared specification and request written clarification for any assumptions. This makes technical and commercial differences easier to evaluate before placing an order.
Conclusion: What to Do Next
A 100-ton weighbridge is a suitable starting point only when its rated capacity, platform size, installation design, and system configuration match the actual application. Confirm the heaviest vehicles and axle loads, size the deck around the fleet, assess site and foundation conditions, and define how weighing data will be captured and used. These checks provide a stronger basis for comparing suppliers and avoiding scope gaps.
To move forward, prepare a vehicle list, a basic site plan, local compliance requirements, and a description of your weighing workflow. Share these with Wanji to discuss a project-specific weighbridge and Electronic Data Systems configuration. Request a detailed quotation that identifies technical specifications, installation responsibilities, schedule assumptions, and after-sales support before making your purchasing decision.
