Weighbridge 100 Ton Selection Guide: Specifications, Sizing, and Site Requirements

A 100-ton weighbridge can be suitable for weighing heavy trucks, but the right model depends on more than its stated capacity. Before requesting a quotation, confirm whether “ton” means metric tonnes or US short tons, identify the heaviest vehicle and axle loads, and check the available site dimensions. You should also decide whether you need a pit-mounted or surface-mounted design, a steel or concrete deck, and data-system features such as ticketing or integration with your ERP. This guide explains how to assess those requirements and prepare a clear purchase specification.

Key Takeaways

• Confirm the capacity unit and local measurement requirements; a metric tonne is 1,000 kg, while a US short ton is 2,000 lb.
• Size the platform for the longest vehicle you need to weigh, not just for the 100-ton capacity label.
• Choose the foundation, deck material, and approach layout to suit ground conditions, drainage, traffic, and installation access.
• Include the weighing indicator, software, peripherals, commissioning scope, and service expectations in the same project specification.

Who This Guide Is For

This guide is for procurement teams, plant managers, engineers, and system integrators comparing a 100-ton truck weighbridge for industrial or commercial use. It is especially useful when the project is at an early planning stage and the buyer needs to define capacity, platform dimensions, civil works, and electronic data requirements. A supplier can quote more accurately when these details are established before equipment selection. Final design should also be checked against local regulations and the site’s engineering conditions.

Understand What “100 Ton” Means

Capacity is not the same as platform size

A weighbridge is a large-scale weighing system that measures a vehicle on a deck supported by load cells. A 100-ton rating describes a maximum weighing capacity under the equipment’s specified conditions; it does not tell you whether the deck is long enough for your trucks or whether the installation meets local legal-for-trade requirements. Buyers should specify the intended unit, such as 100 metric tonnes or 100 US short tons, rather than relying on the word “ton” alone. They should also confirm the applicable verification, division, and accuracy requirements with the relevant local authority or qualified specialist.

Consider vehicle weight and axle loading

List the gross weights and axle configurations of the vehicles that will use the scale, including any future vehicle types the site expects to handle. A vehicle can be within the bridge’s gross capacity while still requiring careful review of concentrated axle loads and how the load is distributed across the deck. The supplier needs this information to assess the platform and load-cell arrangement for the application. Do not select capacity solely by adding a margin to a vehicle’s stated tare weight.

Choose a Deck and Installation Type

Steel or concrete deck

Steel-deck weighbridges are often considered where modular construction, transport, or installation speed is important, subject to the supplier’s design and site conditions. Concrete decks may suit sites that prefer a durable concrete weighing surface, but they require planning for concrete work, curing, and construction sequencing. Material choice affects more than the purchase price: it can influence foundation design, installation logistics, maintenance access, and future replacement work. Ask for the proposed deck construction, protective finish, and maintenance requirements in writing.

Pit-mounted or surface-mounted layout

A surface-mounted weighbridge sits above grade and normally needs approach ramps at both ends, along with sufficient space for vehicles to align and clear the platform. A pit-mounted design can provide a more level crossing surface, but it requires a suitable pit, access for inspection, and effective drainage. The preferred option depends on available land, groundwater and runoff conditions, vehicle flow, and the site’s ability to maintain the structure. Request a layout drawing that shows the deck, approaches, foundations, and service access before civil work begins.

Size the Platform for Your Vehicles and Site

Platform width and length should be based on the widest and longest vehicles to be weighed, their wheel paths, and the weighing procedure. For preliminary planning only, buyers may compare layouts around 3 m wide and 18–24 m long; these are example dimensions, not a universal standard or a final recommendation. A shorter platform may be appropriate for some rigid trucks, while longer combinations may need more deck length or a different weighing method. Confirm actual dimensions with the supplier using your vehicle drawings and site plan.

Measure the full available footprint, including approach ramps, turning space, queuing areas, and the route used by vehicles entering and leaving the scale. Check that trucks can approach straight, stop fully on the platform when required, and exit without conflicting with other traffic. If weighing in both directions is planned, the layout should support safe access from both ends. Include existing utilities, property boundaries, drainage channels, and construction access in the site survey.

Core Specifications to Put in Your Inquiry

Plan the Site Before Ordering

Foundation, drainage, and installation access

Foundation design should be based on geotechnical information, expected loading, the selected weighbridge layout, and local engineering requirements. Do not use a generic foundation drawing without confirming that it suits the actual ground and project design. Drainage is particularly important for pit installations and any location where rainwater or washdown can collect around the structure. The project plan should state who is responsible for civil design, excavation, concrete work, electrical supply, and lifting equipment.

Power, communications, and operating workflow

Identify the available power supply and the route for load-cell and communications cables before construction. If the scale will connect to an existing business system, define the required data fields, interface method, user roles, and ticket workflow before choosing the software package. Wanji’s Electronic Data Systems capabilities can be discussed as part of a complete project scope, including the weighing indicator and any requested data-management components. Confirm compatibility with your existing systems rather than assuming that every interface is included as standard.

A Practical Supplier Selection Framework

1. Document the application: Provide vehicle types, expected maximum gross weights, axle configurations, daily traffic, and weighing direction.
2. Share the site information: Supply a dimensioned layout, ground information if available, drainage conditions, and installation constraints.
3. Compare complete specifications: Review capacity units, platform dimensions, materials, electronics, software, and included peripherals side by side.
4. Clarify responsibilities: Confirm who provides civil drawings, foundations, installation, commissioning, calibration or verification coordination, and operator training.
5. Evaluate the commercial scope: Ask for itemized pricing, minimum order requirements if applicable, estimated production and delivery schedule, warranty terms, and after-sales support.

Price and lead time depend on the configuration, materials, destination, shipping method, and project scope, so request a project-specific quotation instead of relying on a generic estimate. Confirm whether transport, installation, civil works, and local statutory procedures are included or excluded. A lower equipment price may not represent the lower total project cost if essential site work or system components are omitted. Ask the supplier to identify assumptions and exclusions clearly.

Common Selection Mistakes to Avoid

• Confusing capacity units: State metric tonnes or US short tons explicitly in the inquiry and quotation.
• Choosing by capacity alone: A 100-ton rating does not determine whether the platform fits the vehicle or handles its axle-load pattern.
• Leaving civil works until later: Confirm dimensions, foundation responsibilities, drainage, and access before construction starts.
• Overlooking data requirements: Specify reports, tickets, interfaces, and peripherals early to avoid an incomplete operating workflow.
• Assuming approval is automatic: Check local legal-for-trade rules and establish who coordinates required inspection or verification.

Conclusion: Define the Project Before You Specify the Scale

A 100-ton weighbridge is a suitable choice only when its capacity unit, deck dimensions, axle-load design, installation type, and site conditions match the vehicles and weighing process. Start by documenting your heaviest vehicle, its axle configuration, the required weighing workflow, and the available footprint. Then compare complete technical and commercial proposals, including civil works, electronic data systems, commissioning, and local compliance responsibilities.
