1. What is Hydraulic Cylinder Lift Capacity?

Hydraulic cylinder lift capacity refers to the maximum weight a hydraulic cylinder can lift, calculated based on the system pressure and the piston area. It's a critical parameter in hydraulic system design and operation.

2. How Does the Calculator Work?

The calculator uses the hydraulic lift capacity formula:

Where:

• \( Pressure \) — Hydraulic system pressure (bar)
• \( Piston\ Area \) — Cross-sectional area of the piston (cm²)
• \( 9.81 \) — Acceleration due to gravity (m/s²)

Explanation: The formula converts hydraulic pressure and piston area into lifting force, accounting for gravitational acceleration to provide the result in kilograms.

3. Importance of Lift Capacity Calculation

Details: Accurate lift capacity calculation is essential for designing safe hydraulic systems, selecting appropriate components, and preventing system failures or accidents.

4. Using the Calculator

Tips: Enter pressure in bar and piston area in cm². Both values must be positive numbers. The calculator will compute the lift capacity in kilograms.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 9.81 in the formula?
A: Dividing by 9.81 (acceleration due to gravity) converts the force from newtons to kilograms, providing the mass that can be lifted against Earth's gravity.

Q2: What's the difference between bar and psi pressure units?
A: 1 bar equals approximately 14.5 psi. Make sure to use consistent units throughout your calculation.

Q3: How do I calculate piston area?
A: For a circular piston, area = π × (diameter/2)². Make sure to use consistent units (cm² for this calculator).

Q4: Does this calculation account for efficiency losses?
A: No, this is a theoretical maximum. Real-world systems have efficiency losses due to friction, leakage, and other factors.

Q5: Can I use this for double-acting cylinders?
A: This calculation applies to the extending stroke. For retracting, use the annulus area (piston area minus rod area).
