150 Ton Weighbridge Buying Guide: Capacity, Specifications, and Installation
A 150 ton weighbridge is a truck scale designed for vehicles whose gross weight may reach 150 metric tonnes, equivalent to 150,000 kg. To select the right system, confirm the heaviest vehicle and axle loads, choose a platform length and layout that suit your traffic, and specify the weighing instrument and data functions you need. Installation planning matters just as much: the foundation, drainage, access routes, and local measurement requirements must be addressed before ordering. This guide explains what to compare and what information to prepare when requesting a quotation from Wanji.

Key Takeaways
- Confirm that 150 tonnes is suitable for the vehicle’s gross weight and axle-load pattern, not just its advertised payload.
- Specify platform dimensions, construction, installation style, display division, and data interfaces in writing.
- Have the foundation and site layout reviewed against local ground conditions, drainage, and applicable regulations.
- Ask suppliers to itemize equipment, civil works, installation, commissioning, and after-sales support separately.
Who This Buying Guide Is For
This guide is intended for procurement teams, plant managers, engineering contractors, and distributors evaluating a high-capacity truck weighing system. It is relevant to operations that weigh heavy trucks at a mine, port, quarry, steel facility, construction site, or bulk-material terminal. The appropriate configuration depends on the vehicles, traffic volume, site conditions, and local requirements, so a single specification should not be assumed to fit every project. Use the sections below to prepare a comparable technical brief before asking suppliers for proposals.
What a 150 Ton Weighbridge Does
A weighbridge measures a vehicle’s weight while the vehicle is positioned on a platform supported by load cells. The weighing instrument receives the load-cell signals, calculates the measured weight, and presents the result to an operator. Depending on the configured system, weighing records may also be connected to software or other electronic data systems for transaction management and reporting. The complete solution can therefore include more than the steel or concrete platform itself.
Capacity Is Not the Same as Platform Size
The stated 150-tonne capacity describes the scale’s maximum rated weighing capacity; it does not tell you how long or wide the platform should be. Platform dimensions must allow the vehicles being weighed to stand fully on the scale, while the selected system must also be suitable for the loads placed on it. Consider gross vehicle weight, axle spacing, wheel paths, and whether vehicles may enter with concentrated or uneven loads. Ask the supplier to document the capacity and the applicable operating conditions in the quotation.
Types, Materials, and Installation Options
Truck weighbridges are commonly considered as steel-deck or concrete-deck designs, with the best fit depending on the project’s operating environment, construction plan, and maintenance preferences. Steel platforms may suit projects where modular transport and installation are priorities, while concrete decks may be selected where the buyer prefers a concrete weighing surface. These are general selection considerations rather than guarantees of performance; design details and site conditions affect the final decision. Request a clear description of the proposed structure, protective finish, and maintenance requirements.
Pit-Mounted or Pitless Layout
A pit-mounted weighbridge is installed within a prepared excavation, leaving the platform closer to the surrounding ground level. A pitless layout is installed above ground and typically requires vehicle approaches or ramps. The right choice depends on available space, traffic direction, ground and drainage conditions, and how the site will access the equipment for inspection. Ask the supplier and civil contractor to confirm the layout together before construction begins.
Key Specifications to Compare
| Specification | What to confirm |
|---|---|
| Rated capacity | Confirm 150 tonnes (150,000 kg) and clarify the intended vehicle and loading conditions. |
| Platform dimensions | Match length and width to vehicle dimensions, axle spacing, and site traffic flow. |
| Platform construction | Identify steel or concrete deck, module arrangement, surface finish, and maintenance access. |
| Weighing instrument | Specify display, operating functions, data storage, and required connections to electronic systems. |
| Display division | State the required increment and verify that it suits local rules and the intended use. |
| Installation scope | Define foundation responsibilities, transport, assembly, commissioning, and operator instruction. |
For early layout discussions, an 18 m × 3 m platform can be used as an illustrative size example, not as a universal 150-tonne standard. The actual dimensions should be established from the vehicle fleet and site plan. Likewise, a 20 kg display division can be included as a requested example for quotation comparison, but it should not be treated as the default or as proof of legal suitability. Ask each supplier to state the proposed division and applicable compliance assumptions explicitly.

Match the Weighbridge to the Application
Start by listing the vehicle types that will use the scale, including their overall length, axle arrangement, and maximum loaded weight. A weighbridge used for occasional inbound and outbound truck transactions may need a different operating workflow from one serving continuous bulk-material traffic. Consider whether the scale must integrate with gates, identification devices, printers, or management software. Wanji can review the application details with your team so the quotation reflects the intended weighing process and data requirements.
Selection Framework for Buyers
- Define the load: Record maximum gross vehicle weight, axle configuration, and expected loading patterns.
- Confirm the layout: Measure available space and identify vehicle approach, turning, queueing, and exit routes.
- Choose the construction and installation style: Compare steel or concrete deck options and pit-mounted or pitless arrangements.
- Specify the electronics: List display, recordkeeping, communication, and software interface needs.
- Check local requirements: Confirm applicable rules for commercial weighing, inspection, verification, and installation with the responsible local authority or qualified adviser.
- Compare complete proposals: Review equipment scope, civil work assumptions, schedule, training, warranty terms, and service arrangements.
Installation Requirements and Planning
Installation begins with a site review, not with the delivery of the platform. The engineering team should assess ground conditions, foundation design, drainage, cable routing, power supply, and vehicle access before civil works are finalized. The foundation must be designed for the proposed equipment and site conditions by qualified professionals; do not rely on a generic drawing without checking that it applies to your project. Clear responsibility for design review and construction supervision should be agreed between the buyer, supplier, and civil contractor.
Commissioning and Operational Readiness
Before routine use, confirm that the scale is assembled as specified, the weighing instrument and load cells are connected correctly, and the system has been checked under the procedures required in your location. Arrange operator instruction on normal weighing, record handling, cleaning, and basic fault reporting. Agree how service requests will be raised and which maintenance tasks are the buyer’s responsibility. Keeping installation records and the final equipment configuration can make later support and troubleshooting more straightforward.
Pricing, MOQ, and Lead Time
The price of a 150-tonne weighbridge depends on configuration and project scope, including platform dimensions, materials, electronics, installation arrangement, transport, and any required software connections. Site-specific civil work and local inspection requirements can also affect the total project cost. Minimum order quantities and lead times should be confirmed directly with the supplier because they may vary with customization, production scheduling, destination, and shipping arrangements. Request an itemized quotation that distinguishes the weighbridge equipment from optional services and site work.
Supplier Evaluation Checklist
- Does the proposal clearly state capacity, dimensions, construction, and display division?
- Are the foundation interface, installation boundaries, and buyer-supplied work documented?
- Can the supplier explain how the weighing system will support your required data workflow?
- Are commissioning, operator instruction, warranty terms, spare parts, and service channels described?
- Does the supplier identify assumptions that require confirmation, including local regulatory approval?
Common Buying Mistakes to Avoid
One frequent mistake is selecting capacity based only on payload while overlooking the truck’s gross weight and axle loads. Another is ordering a platform before confirming vehicle dimensions and the available approach space. Buyers may also compare headline prices without checking whether foundations, installation, electronics, or commissioning are included. Resolve these questions in the specification and quotation stage to reduce the risk of scope gaps during installation.
Conclusion: Your Next Steps
A 150 ton weighbridge is suitable only when its rated capacity, platform layout, electronics, and installation design match the vehicles and operating site. Before purchasing, document your heaviest vehicle and axle configuration, confirm the required platform dimensions and data functions, and have the foundation and local compliance requirements reviewed. Then compare itemized proposals that clearly state equipment scope, installation responsibilities, lead time, and service support.
