Turntable capacity (lb)6,000
Total system load (lb)4,398
Motor (HP)0.25
Duty (0=light, 1=med, 2=heavy)1
How to Use This Calculator
- Enter the load weight (lb) — the maximum weight placed on the turntable.
- Set the load diameter (in) — the footprint or diameter of the largest load.
- Input the rotation speed (RPM) required by your process.
- Enter cycles per hour to determine duty classification.
- Use Platform dia (in) and Turntable capacity (lb) to select the right unit, and Motor (HP) for power planning.
How the result changes with Load diameter (in)
| Load diameter (in) | Platform dia (in) |
|---|---|
| 23 | 29 |
| 50 | 56 |
| 82 | 88 |
| 109 | 115 |
What each input means
- Load weight (lb)
- Maximum load weight on the turntable.
- Load diameter (in)
- Maximum load diameter or footprint.
- Rotation speed (RPM)
- Desired rotation speed.
- Cycles per hour
- Number of rotation cycles per hour.
What each result means
- Platform dia (in)
- Recommended platform diameter.
- Turntable capacity (lb)
- Standard turntable capacity to select.
- Total system load (lb)
- Load plus platform weight.
- Motor (HP)
- Minimum drive motor horsepower.
- Duty (0=light, 1=med, 2=heavy)
- Duty classification.
How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersLoad weight (lb) = 4000, Load diameter (in) = 48, Rotation speed (RPM) = 3, Cycles per hour = 20 = 4 input(s) provided
- Calculate Platform diaPlatform dia = loadDiaIn + 654 = 54
- Calculate Turntable capacity6000 = 6000
- Calculate Total system loadTotal system load = loadWeightLb + platformWeightLb4398 = 4398
