Integrated Weighment and Camera System for Ready Mix Concrete Batching Plants

The Problem: Nobody Can Prove What Actually Left the Plant

A transit mixer leaves your batching plant loaded and reaches the site thirty minutes to a couple of hours later. In that window, there's no independent record of exactly how much concrete was on board when it left — only what a weighbridge operator wrote down, if anyone wrote it down at all.

This gap creates two very different, very costly problems for RMC plant owners:

• Short-loading and material theft — a driver, or someone with access to the loading process, can under-fill a mixer relative to what's billed. Without a hard, tamper-proof weight record, this is nearly impossible to catch trip by trip.
• Delivery disputes with credit customers — many RMC plants supply on credit to builders and contractors who pay after a billing cycle. It's common for a customer to claim a particular trip never arrived, or arrived short, and without proof the plant has no strong way to counter that weeks later.

The Fix: Tie the Weight to the Vehicle, Automatically, With a Photo

When it's time to collect payment and a customer disputes a trip, the plant has a timestamped photo of that exact vehicle at that exact weight, on that exact date — not a memory or a hand-written note. Most disputes end the moment that slip is shown.

What This Actually Protects: Theft, Production, and Quality — Not Just Billing

A Second, Easy-to-Miss Cost: Hardened Concrete Building Up Inside the Drum

There's a mixer-maintenance problem that usually has nothing to do with theft at all, but quietly costs plants just as much. If a transit mixer isn't washed out properly after every trip — or the drum isn't rotated enough to keep the last bit of concrete from settling — a thin layer hardens onto the inside wall of the drum. Nobody sees it happen, because it's inside a closed, rotating drum. It builds up trip after trip if it isn't caught.

The effect is that the mixer's usable carrying capacity quietly shrinks. By the time this becomes obvious, someone usually has to physically break the hardened concrete out of the drum — a slow, labor-heavy job that takes the vehicle off the road and costs real manpower to complete.

This is exactly what the empty (tare) weighment already catches, at no extra step. Since each vehicle has a known baseline empty weight, the system compares today's tare weight against that baseline on every trip. If a vehicle's "empty" weight starts creeping upward over successive trips, there's only one explanation: something solid has built up inside the drum — a clear, early signal to pull the vehicle in for a wash-out, before it turns into a costly breakout job.

Where This Fits in Sazs RMC ERP

This isn't a separate add-on — it's the same weighbridge automation and ANPR camera integration already built into Sazs RMC ERP, applied specifically to the transit-mixer trip cycle. It connects directly into weighbridge load-cell capture, ANPR vehicle identification and photo capture, and the GST e-invoice & e-way bill flow that the same trip data feeds automatically.

Running Schwing Stetter batching plant controllers? This weighment-and-camera flow works alongside Sazs ERP's direct Schwing Stetter Integration, so batch-wise production, dispatch and weighment stay in sync on one platform.
