How Mechanical Scales Work — A Simple Guide for Shopkeepers and Traders

⚙️ Introduction

Digital scales may show instant numbers, but mechanical weighing machines operate using simple physics — and they’re still widely used across Gujarat.

Understanding how they work helps you:

• Use them more effectively

• Calibrate them properly

• Fix common issues on your own

Let’s break it down.

🧩 Main Components of a Mechanical Scale

1. Lever/Beam Mechanism – The heart of the machine that balances the weight

2. Pan or Platform – Where the item is placed

3. Fulcrum and Pivots – Allow the beam to tilt and show imbalance

4. Counter Weights (Iron or Brass) – Used to counterbalance the load

5. Graduated Markings or Scale Indicator – Show the weight measurement

🔄 How Does It Work?

1. You place an item on the pan/platform

2. The beam tilts due to the item’s weight

3. You add standard counterweights to the other side

4. Once the beam is level — the two weights are equal

5. The total of your counterweights gives you the item’s weight

It’s a pure mechanical balance — no batteries, no electronics.

📏 Accuracy Tips

• Always use certified iron weights

• Calibrate the empty machine to zero

• Keep the surface flat

• Avoid weighing during wind or vibration

• Re-stamp yearly under Legal Metrology norms

🛠️ Maintenance Tips

• Keep the pivot points clean

• Oil the moving parts occasionally

• Avoid overloading

• Store weights separately to avoid damage
