What size weighbridge do you need for a logistics park / mine / port?
These three site types come up constantly in our quote conversations, and even though they all fall under "large-capacity truck scale," the actual sizing logic is different enough for each one that lumping them together usually leads to the wrong answer. I work with Fujian Fangda Weighbridge manufacturer, and this is roughly how we walk through each one when someone's speccing a new installation.
Logistics parks — the widest range of vehicle types on one scale
This is probably the trickiest sizing conversation of the three, not because the vehicles are the heaviest, but because a logistics park typically sees the widest mix of vehicle types crossing the same scale — everything from smaller regional delivery trucks to fully loaded long-haul combinations, sometimes on the same day.
For most logistics parks handling standard commercial freight, a 60-ton platform covers the bulk of what comes through, since that's the standard range for fully loaded semi-trailers and typical 5-6 axle configurations. But the sizing question isn't just about peak vehicle weight — it's also about platform length and throughput. If trucks are queuing to get weighed and turnaround time matters operationally, a longer platform or a second scale lane sometimes matters more than going up in tonnage capacity. We've had customers who sized correctly for weight but ended up with a bottleneck because they didn't think through how many vehicles per hour actually needed to cross the platform during peak periods.
The other thing that catches people off guard: logistics parks tend to grow their tenant base and vehicle mix over time in ways that are hard to predict at the planning stage. A park that starts out serving regional delivery trucks might, within a few years, be handling heavier long-haul freight or specialized cargo that wasn't part of the original plan. Building in some capacity margin, and thinking about platform length for future expansion, tends to pay off more here than in more predictable single-use sites.
Mines — heaviest vehicles, most predictable weight, hardest environment
Mining sites are actually the more straightforward sizing conversation in one sense — you generally know exactly what equipment is running the route, and haul truck weights are well documented by the manufacturer, so you're sizing against known numbers rather than estimating future growth. Depending on the haul trucks in use, this often means 100-ton to 150-ton-plus platforms, and the conversation is less about "which capacity" and more about platform length and load cell array configuration to handle both total weight and how that weight distributes across the platform.
Where mining sizing gets harder is the environment, not the tonnage. Dust, vibration from heavy equipment traffic, temperature extremes depending on the region, and mechanical shock from trucks that aren't always driven gently onto the platform all put more stress on load cells than the rated capacity alone suggests. We spend more time in mining quote conversations talking about load cell build quality and overload tolerance than we do in most other site types, because a cell that's technically rated for the job but not built for the actual site conditions tends to fail faster than the spec sheet would suggest. If your operation involves trucks that are routinely, even if unofficially, running over rated weight — which happens more in mining than most site types admit — that's worth specifically raising in the sizing conversation rather than assuming standard overload tolerance covers it.
Ports — heavy capacity plus corrosive environment
Port and bulk cargo terminal scales usually land in a similar tonnage range to mining — 100 to 150-plus tons depending on the cargo and vehicle types moving through the facility — but the environmental challenge is different. Salt air and near-constant humidity create a corrosion profile that's distinct from the dust and mechanical shock concerns at a mining site, and it affects load cell housing, sealing, and cable connections differently over time.
This is a case where the same rated capacity and the same general build quality on paper can perform very differently depending on whether the load cell was actually designed with a coastal, high-salinity environment in mind. We've seen cells that held up fine in inland industrial applications fail faster than expected at port installations, purely because the corrosion resistance wasn't specifically accounted for in the original design. It's worth asking directly about this rather than assuming standard IP68 sealing automatically covers coastal conditions the same way it covers a dusty inland site.
Platform configuration at ports also tends to involve more thought about traffic flow and queuing than mining, since ports typically have more consistent, higher-frequency truck traffic than a single-site mining operation, closer in some ways to the throughput concerns you see at logistics parks, just at a heavier tonnage range.
The common thread across all three
In every case, the tonnage number is only part of the sizing conversation. Platform length, environmental conditions, load cell build quality suited to the specific site, and realistic throughput or growth expectations all matter as much as the peak weight rating, and skipping past those in favor of just picking a tonnage number is where a lot of sizing mistakes happen.
If you're planning a scale for a logistics park, mine, or port and want to actually work through the specifics of your site rather than defaulting to a generic capacity recommendation, that's a conversation worth having before construction starts. Getting it right upfront is a lot cheaper than retrofitting a scale that was undersized, under-configured for its environment, or built without enough platform length for how the site actually operates.
