CONVEYOR BELT WEIGHT CALCULATOR

Weight and Roll Size
Before You Order.
Planning a crane lift, a truck load, or checking whether a roll will pass through a gate? Enter the belt details below to get an estimate of the belt weight, the weight of the roll and its outside diameter. The numbers are estimates for planning – the actual figure for your order is on our dispatch documents.
How the Calculator Works
A fabric belt is made of two things: rubber covers and fabric plies (with the thin rubber layers between them). The calculator adds the weight of each per square metre and multiplies by the width and length:
- Rubber: about 1.15 kg per square metre for every 1 mm of cover (general purpose compounds; heat and fire resistant compounds can be a little heavier).
- Each ply: about 1.1 to 2.1 kg per square metre, rising with the fabric strength – see the table below.
- Roll diameter: worked out from the belt thickness, the length and the core size, assuming a tight wind.
| Ply Strength (N/mm) | Approx. Thickness per Ply (mm) | Approx. Weight per Ply (kg/m²) |
|---|---|---|
| 100 | 0.8 | 1.1 |
| 125 | 0.9 | 1.25 |
| 160 | 1.0 | 1.4 |
| 200 | 1.2 | 1.6 |
| 250 | 1.35 | 1.8 |
| 315 | 1.6 | 2.1 |
Worked Example
1000 mm wide, EP 400/3 (about 125 N/mm per ply), 5 mm top and 2 mm bottom cover, 100 m long:
- Rubber: 7 mm × 1.15 = 8.05 kg/m²
- Plies: 3 × 1.25 = 3.75 kg/m²
- Total: 11.8 kg/m² × 1.0 m wide = about 11.8 kg per metre
- Roll of 100 m: about 1,180 kg, plus the core
