Hydraulic Jack Capacity Formula:
| From: | To: |
Hydraulic jack capacity refers to the maximum weight a jack can safely lift. It's determined by the piston area and the system's pressure rating, following the fundamental hydraulic principle that pressure applied to a confined fluid is transmitted undiminished in all directions.
The calculator uses the hydraulic jack capacity formula:
Where:
Explanation: The formula calculates the force output based on the hydraulic principle that force equals pressure multiplied by area.
Details: Proper capacity calculation is essential for safety and efficiency in lifting operations. Using a jack with insufficient capacity can lead to equipment failure, property damage, and personal injury.
Tips: Enter the piston area in square centimeters, the pressure rating in bar, and select your preferred output unit (tons or kN). All values must be positive numbers.
Q1: What's the difference between tons and kN as capacity units?
A: Tons measure force in the imperial system (1 ton = 2000 pounds), while kN (kilonewtons) measure force in the metric system (1 kN = 1000 newtons). 1 ton is approximately equal to 8.896 kN.
Q2: How do I measure piston area?
A: For a circular piston, area = π × (diameter/2)². Measure the piston diameter and calculate accordingly.
Q3: What is a typical pressure rating for hydraulic jacks?
A: Most hydraulic jacks operate between 700-1000 bar, but this can vary significantly by manufacturer and jack type.
Q4: Should I include a safety factor in my calculations?
A: Yes, it's recommended to use a jack with at least 1.5 times the calculated capacity requirement for safety margins.
Q5: Can this calculator be used for all types of hydraulic jacks?
A: This formula applies to all hydraulic jacks based on the same fundamental principle, including bottle jacks, floor jacks, and trolley jacks.
