Most weighbridges give you a single number on a slip. We measure every wheel, both hitched and unhitched, and produce a digital report that tells you exactly where your weight is, where it's allowed to be, and how much margin you have left. So you can travel knowing your rig is safe, legal, and balanced.
A typical weighbridge gives you a total weight on a printout. We measure your rig in six distinct phases — and every measurement feeds the formula engine that builds your full report.
Up to 4 wheel pads under the unhitched van. We capture each corner individually, then derive front/rear axle totals, side balance, and Tow Ball Mass (Total minus Axle).
4 pads under the tow vehicle on its own. Front-left, front-right, back-left, back-right. Establishes your vehicle's true unloaded weight before the van is connected.
All 8 pads at once with the rig connected. The shift in vehicle rear-axle weight becomes the measured Tow Ball Mass — and the total gives you your real-world GCM.
Tow ball lever arm, rear bar overhang, axle reference. A side photo with three marker positions — the source of truth for your permanent load planner.
Up to 3 test rows with known weights at known distances. The system compares measured tow ball change against what the geometry predicts — measurement errors caught here, not on the road.
11 distinct checks against your manufacturer plate ratings. ATM, GTM, GVM, GCM, every axle limit, max tow ball mass, payload, caravan-to-car ratio. Pass / fail, in plain English.
Most weighbridges weigh one axle at a time — drive on, drive off, drive on, drive off. The numbers shift between readings because vans settle, suspension flexes, and ground level isn't perfectly even. You end up with eight measurements that don't quite add up.
Our setup uses eight calibrated wheel pads in a single configuration: four under the tow vehicle, four under the van. Every wheel is captured at the same moment. The maths works out because the inputs are consistent. And because we're mobile, we bring the system to your driveway, your storage facility, or wherever your rig is sitting — fully loaded, ready to travel, the way it actually is.
Unhitched gives you the caravan's true weight on its own — your real ATM, your real tow ball mass, and your real GTM. These are the legal numbers that go on insurance and registration paperwork.
Hitched shows what actually happens when the rig is connected: how weight transfers from the caravan onto the tow vehicle's rear axle, what your real-world GCM is, and whether the vehicle is operating within its towing rating with the van on the back. Both pictures matter. Together they tell you whether your setup is safe before you turn the key.
During your weigh-in, we take a side-on photo of your van and measure three reference distances: tow ball forward of axle, axle centre, and rear bar behind axle. These distances become the source of truth for your van's geometry — and the key to predicting how loading affects tow ball weight from anywhere along the chassis.
After we've captured your measurements, the formula engine runs every reading against every manufacturer-rated limit on your compliance plates. You see exactly which limits you're inside, and which (if any) you're not.
Every weigh-in produces a digital report you can share with anyone — your insurer, a workshop, your mechanic, your trip-planning partner. No login. Just a link that works on any device.
Both weigh-ins include the digital report, geometry-based load planner, and 11 compliance checks. Travel costs may apply outside the metro — you'll be notified at the time of booking.
