100 Ton Electronic Weighbridge: Specifications, Installation, and Buying Guide

A 100 ton electronic weighbridge is a truck scale designed to measure vehicle weight up to a rated capacity of 100 metric tonnes, or 100,000 kg. It combines a load-bearing platform, load cells, a junction or signal-processing system, and a weight indicator that displays the measurement. The right configuration depends on your heaviest loaded vehicle, truck dimensions, site conditions, and local weighing requirements—not capacity alone. In this guide, we explain the specifications to confirm, the installation decisions that affect performance, and how to evaluate suppliers before requesting a quotation.

Key Takeaways

  • Confirm that 100 tonnes covers the gross weight of the heaviest vehicle, with suitable consideration for axle loads and operating conditions.
  • Choose platform length, width, materials, and installation type around the vehicles and site—not a generic specification sheet.
  • Plan foundations, drainage, power, cabling, and access before delivery to reduce installation risk.
  • Request a complete technical and commercial scope from each supplier, including installation responsibilities, commissioning, and after-sales support.

Who This Buying Guide Is For

This guide is intended for procurement teams, plant managers, project engineers, and distributors evaluating an electronic weighbridge for commercial or industrial vehicle weighing. It is relevant to applications such as logistics yards, quarries, mines, construction sites, ports, agricultural operations, and manufacturing facilities. Each site has different vehicle flows, environmental conditions, and operating rules, so final specifications should be agreed with the project team and checked against applicable local requirements. We recommend sharing actual vehicle and site information with suppliers before comparing quotations.

How a 100 Ton Electronic Weighbridge Works

When a vehicle drives onto the platform, the load is transferred through load cells, which convert force into electrical signals. The weighing electronics process those signals and show the vehicle weight on an indicator, often with a connected computer or weighing-management system. Depending on the configured system, operators may record gross, tare, and net weights and associate weighments with vehicle or transaction details. The exact functions, data interfaces, and software options should be confirmed in the quotation.

Specifications to Confirm Before You Buy

Rated Capacity and Weighing Division

A 100 tonne capacity equals 100,000 kg of gross load on the weighbridge, but capacity by itself does not establish whether a model suits a particular vehicle. Ask the supplier to state the rated capacity, displayed division or increment, and applicable accuracy or verification requirements in writing. These details can vary by indicator, configuration, intended use, and local metrology rules. Do not treat a displayed increment as a guarantee of legal-for-trade accuracy.

Platform Dimensions and Configuration

Platform length and width should accommodate the longest and widest vehicles that need to be weighed, while allowing safe approach and exit. As an illustrative planning reference only, a project team might evaluate a platform around 18 m long and 3 m wide; these dimensions are not a universal standard or a recommendation for every 100 tonne installation. Confirm the actual truck wheelbase, overall vehicle length, lane alignment, and required weighing method before selecting a deck. Modular platforms can be practical for transport and site planning, but the number and arrangement of modules are configuration-specific.

Deck Material, Load Cells, and Electronics

Steel and concrete are common deck approaches, each with different implications for transport, construction, maintenance, and site layout. Steel decks may suit projects seeking prefabricated components, while concrete decks typically require more on-site construction planning; suitability depends on the project conditions. Ask for the proposed load-cell type and quantity, indicator model, junction-box arrangement, cable protection, and available data interfaces. Wanji supplies electronic weighing solutions and can discuss configuration options based on the intended vehicle, environment, and integration requirements.

Specification area What to confirm Why it matters
Capacity 100 tonnes / 100,000 kg rated capacity and operating limits Checks fit with loaded vehicles and use conditions
Platform Length, width, deck material, and module layout Supports vehicle fit, access, and installation planning
Weighing system Load cells, indicator, cabling, software, and interfaces Defines measurement display and data-handling scope
Site works Foundation drawings, drainage, power, and approach lanes Reduces civil-work and commissioning uncertainties

Installation Requirements and Planning

Survey the Site Before Finalizing the Design

Begin with a site survey that records available space, access roads, ground conditions, drainage, utilities, and the planned traffic direction. The foundation design should be based on site-specific engineering information and the weighbridge supplier’s drawings, rather than a generic slab assumption. Check whether trucks can approach and leave without sharp turns, queuing conflicts, or interference with other plant traffic. Confirm local construction and weighing requirements before ordering equipment.

You will get efficient and thoughtful service from Wanji.

Coordinate Foundations, Utilities, and Delivery

Agree who is responsible for civil works, equipment supply, transport, lifting, electrical work, and commissioning. Foundation dimensions and reinforcement details must come from the approved project design, and concrete curing or readiness should be confirmed by the responsible construction team before installation. Plan power supply, protected cable routes, indicator location, and any computer or network connections in advance. A 24 V power arrangement may be available in some configurations, but buyers should verify the actual electrical specification rather than assume it is included.

Commissioning and Handover

After installation, the supplier and site team should inspect the platform, connections, indicator operation, and vehicle approach conditions. Any calibration, verification, or legal-for-trade process must follow the applicable local rules and be handled by authorized parties where required. Request operating instructions, maintenance guidance, wiring documentation, and a clear explanation of which party provides on-site support. Keep commissioning and acceptance criteria in the purchase contract so both sides understand what constitutes project handover.

How to Select the Right Weighbridge

Match the Scale to Vehicles and Workflows

List the vehicle types, their gross weights, axle arrangements, dimensions, and expected weighing frequency. Establish whether trucks will be weighed once or twice per visit, whether the system needs to identify vehicles, and whether operators require printed tickets or electronic records. Consider peak traffic as well as normal operations, since queueing and access can affect the practical value of a scale. If your weighing process must connect to existing business software, define the required data fields and interfaces before selecting the indicator.

Compare Complete Scope, Not Just Equipment Price

Quotations can differ in what they include, so compare like-for-like specifications and responsibilities. Ask whether the price covers the platform, load cells, indicator, software, transport, installation supervision, commissioning, training, and documentation. Clarify minimum order quantity, production lead time, payment terms, warranty scope, spare-parts availability, and the destination port or delivery location. Wanji can review your project requirements and prepare a configuration for quotation; final cost and lead time depend on the selected design, order details, and delivery arrangements.

Evaluate Supplier Support

Request a written technical proposal with drawings, equipment descriptions, exclusions, and a list of buyer-supplied work. Check whether the supplier can explain foundation interfaces, installation sequence, electrical requirements, and the support available after delivery. Ask how technical questions, replacement parts, and service requests are handled for your location. Clear scope and responsive communication are useful indicators of project readiness, but they should be verified through the supplier’s actual proposal and agreed service terms.

Common Buying and Installation Mistakes

  • Choosing by capacity alone: A 100 tonne rating does not establish that the platform length, width, or axle-load arrangement fits your vehicles.
  • Using generic foundation details: Site soil, drainage, and engineering conditions require project-specific review.
  • Overlooking operating data: Confirm whether you need ticket printing, transaction records, vehicle identification, or software integration.
  • Comparing incomplete prices: Exclusions for civil works, delivery, installation, and verification can change the total project cost.
  • Leaving local compliance until the end: Verify relevant weighing, construction, and electrical requirements before purchase.

Conclusion: Next Steps for Buyers

A 100 ton electronic weighbridge is suitable only when its rated capacity, platform dimensions, weighing electronics, and installation plan match the intended vehicles and site. Start by documenting vehicle weights and dimensions, weighing workflow, location conditions, and any local compliance requirements. Then request a detailed technical and commercial proposal that separates equipment from civil works, delivery, installation, and commissioning responsibilities. We at Wanji can use that information to discuss a suitable electronic weighbridge configuration and provide a project-specific quotation for your review.
