Load - Pressure Correlation For Model YA1544A & YA1545
Always monitor the force applied to workpiece by using a load cell and indicator or you may monitor pressure
developed in the ram by using an inline pressure gauge, then calculate the applied force using the formula:
F = P x A
For model BK104,
A
= 0.998 in² ;
For model BK105,
A
= 2.411 in²
Example1
Model YA1544A lifting 5,000 lbs will require what
presure?
Pressure
= 5,000 lbs
0.998 in² = 5,010 psi
where
F = Force/ Load (lbs);
P = Hydraulic working pressure (psi) and;
A = Ram effective area (in²)
Example2
Model YA1545 operating at 6,000 psi will gener-
ate what force?
Force
= 6,000 psi x 2.411 in
2
= 14,466 lbs
