Engineering Calculator
Staircase Hatch Calculator
Estimate lifting force for trap doors, stairs, basement access covers, or heavy floor hatches. Results are for preliminary product selection and should be reviewed against your real drawing, bracket geometry, duty cycle and safety requirements.
Input parameters
How this estimate works
Use this for heavy access hatches, stair covers or floor panels. Stability and bracket strength must be checked separately.
| What to confirm before ordering | Why it matters |
|---|---|
| Real mounting points and actuator angle | Small angle changes can increase required force significantly. |
| Load center of gravity and offset distance | Offset loads create extra torque and bracket stress. |
| Stroke, speed, voltage and duty cycle | The same force can require different motor and gearbox choices. |
| Environment and protection level | Dust, water, outdoor use and temperature affect product selection. |
