A 150 ton heavy duty truck scale is a weighbridge designed for vehicles whose loaded weight may approach a maximum capacity of 150 metric tonnes, or 150,000 kg. Choosing the right system involves more than matching the capacity to a truck: buyers should confirm axle loads, vehicle dimensions, site conditions, weighing procedures, required approvals, and after-sales support. This guide explains the key options and procurement checks so you can prepare a suitable project specification before requesting a quotation from Wanji.

This guide is for procurement teams, plant managers, engineering contractors, and operators sourcing a high-capacity weighbridge for industrial vehicle weighing. Typical environments may include mining, bulk materials handling, heavy manufacturing, ports, and infrastructure projects. Each site has different vehicle patterns, ground conditions, and legal requirements, so the specification should be developed around the actual operation rather than a generic product description.
A truck scale uses a platform supported by load cells to measure the force applied by a vehicle. The weighing indicator receives signals from the load cells and converts them into a displayed weight; connected software can support functions such as recording transactions and generating reports, depending on the system configuration. A complete weighing solution may also include access controls, traffic lights, printers, or interfaces to a customer’s management system.
The 150-tonne figure describes the scale’s nominal maximum capacity, but it does not alone establish suitability for every vehicle. Buyers should provide the maximum gross vehicle weight as well as axle loads, wheel spacing, and how the vehicle enters and exits the platform. The supplier can use this information to assess platform arrangement and load distribution; final design depends on the project specification and applicable requirements.
Steel-deck weighbridges can be assembled from modules and may suit projects where installation or relocation flexibility is important. Concrete-deck designs use a concrete weighing surface and may be considered where the buyer prefers that surface type or has specific site and operating needs. Neither option is universally better: compare structural design, surface maintenance, transport, installation method, and the supplier’s documented specifications.
A pitless weighbridge is installed above grade and typically requires approach ramps, so the available site length and vehicle turning area need review. A pit-mounted scale sits within a prepared foundation and may offer a level crossing surface, but it requires civil works and appropriate drainage and access planning. The right choice depends on the layout, ground conditions, drainage, traffic flow, and maintenance access at the installation site.
Start with the vehicles that will use the scale, not just the stated capacity. Record the longest and widest vehicle, maximum loaded weight, axle arrangement, wheelbase, and whether trucks need to stop fully on the platform. For initial layout discussions, an 18 m × 3 m platform can be used as an example dimension only; it is not a universal recommendation, and final dimensions should be checked against the vehicle fleet and site plan.
Also define how the scale will be operated. A facility weighing vehicles in both directions may need different traffic controls from a site with one-way entry and exit, while unattended weighing may call for identification or access-control functions. If the scale must produce records for billing, inventory, or dispatch, specify the required data fields and software interfaces before equipment selection.
Ask the supplier to confirm the rated capacity, platform length and width, module arrangement, and design assumptions for your vehicle loads. Request relevant drawings and technical documentation for review by your engineering team. Make sure the proposed scale addresses the actual axle loading and operating pattern, rather than relying on capacity alone.
Define the weighing interval, display resolution, recordkeeping needs, and acceptable operating procedure with the supplier. The display division or resolution is not the same as verified weighing accuracy, and legal-for-trade use may require approvals, inspection, or calibration under local rules. Confirm which requirements apply in the installation jurisdiction and who is responsible for arranging the required steps.
You will get efficient and thoughtful service from Wanji.
Provide a site plan, available approach length, ground information, drainage details, and utility locations where available. Clarify whether the quotation covers foundations, ramps, cabling, installation, and commissioning, or whether those items are handled by a local contractor. A clear division of responsibilities helps avoid schedule gaps and unexpected project costs.
List the required indicator functions, printer needs, reporting fields, and connections to existing systems. Ask whether the quoted configuration includes the software, computer, peripherals, and integration work you need, since these may be separate options. Wanji, as an Electronic Data Systems supplier, can discuss the weighing electronics and data functions as part of a project-specific configuration.
There is no reliable single price for every 150-tonne weighbridge because the delivered scope can vary substantially. Cost factors may include platform material and dimensions, load cells and indicator, software, foundation work, transport, installation, and local compliance requirements. For an accurate comparison, request quotations that state the same technical scope and clearly separate equipment from site work and optional services.
Ask suppliers to confirm minimum order requirements, manufacturing schedule, shipping arrangements, and the information they need to begin engineering. Lead time can depend on configuration, production planning, shipping, and site readiness, so request a project-specific schedule rather than relying on a general estimate. Include commissioning, training, spare parts, and service response arrangements in the procurement discussion.
Compare suppliers using a written scope matrix rather than headline price alone. Ask each bidder to identify exclusions and assumptions, especially for foundations, installation, and software integration. This makes differences visible before purchase and gives your team a firmer basis for evaluating total project requirements.
One common mistake is selecting a scale by gross capacity without reviewing axle loads, wheel spacing, or platform length. Another is assuming that legal approval, calibration, civil works, or software integration is included when the quotation does not say so. Buyers can reduce these risks by sharing a vehicle list and site details early, then confirming each responsibility in the technical and commercial documents.
It is also unwise to choose a pit or pitless arrangement before considering drainage, approach geometry, and maintenance access. Similarly, a software feature should be described in operational terms, such as required reports or data fields, instead of being accepted as a vague promise of “integration.” Requesting drawings and a clearly itemized scope helps align procurement, engineering, and operations teams.
A 150 ton heavy duty truck scale is suitable only when its capacity, platform, structure, electronics, and installation plan match the vehicles and site where it will operate. Begin by documenting the heaviest vehicle and axle loads, required platform dimensions, daily weighing workflow, local compliance needs, and available site conditions. Then use those details to compare a complete, itemized proposal rather than capacity or price in isolation.
To discuss a project-specific solution with Wanji, prepare your vehicle specifications, site plan, preferred installation type, and required software or reporting functions. Wanji can review the information and clarify configuration options, quotation scope, and the next engineering inputs needed for a 150-tonne weighbridge project.
