This number helps you pick a coupling that can handle extra stress and keeps your machine safe.
Assess operating conditions
Think about where you use your excavator. Does it work in hot, dusty, or wet places? The coupling’s material matters here. Some couplings change if they get too hot. Pick one that works for your job site. Good couplings give you:
Great shock absorption
Less vibration
Better power transfer
Fixes misalignment
Less stress on parts
Longer life for important parts
Measure load and torque
You need to know the load and torque your excavator uses. Torque is the force that turns the parts. Different machines need different torque. Use this table to compare:
Excavator Class | Operating Weight (kg) | Min Torque (Nm) | Max Torque (Nm) | Motor Displacement (ml/r) | Typical Gearbox Ratio |
|---|---|---|---|---|---|
10-Ton | 10,000–12,000 | 800 | 1,200 | 40–80 | 25:1–35:1 |
20-Ton | 18,000–22,000 | 1,800 | 2,800 | 80–160 | 30:1–40:1 |
35-Ton | 32,000–38,000 | 3,200 | 4,500 | 160–250 | 35:1–50:1 |
50-Ton | 45,000–55,000 | 4,500 | 6,500 | 250–350 | 45:1–60:1 |
Industry rules like ISO 4409 and ISO 4406 help you measure load and torque. When you know these numbers, you can pick the right coupling. This keeps your excavator strong and working longer.
Tip: Always check your numbers before you buy a new coupling. This step saves you time and money.
