Thru-Hole Hydraulic Rams
Calculation of Forces Using Straps and Levers
Figure #1
When the distance AB is equal to
the distance BC the force upward
from Model 020-011-011DE Ram
“C” is equal to the downward force
“A” on the part.
Figure #2
The downward force “A” is equal to the
upward force “C” times a ratio of the
distance BC:AB.
Example:
AB = 2", BC = 4", Force “C” = 1,000 lbs.
Force “A” = Force “C” x BC
AB
“A” = 1,000 lbs. x 4
2
“A” = 2,000 lbs.
Figure #3
When Force “B” from Model 020-011-011DE Hollow Bore
is divided between “A” & “C”, the forces at “A” & “C” are in
inverse ratio to the distance AB & BC respectively.
Force “A” = Force “B” x BC
AB
Force “C” = Force “B” x AB
AC
Example:
AB = 2
"
, BC = 4,
"
Force “B” = 1,000 lbs.
Force “A” = 1,000 lbs. x 4 = 666.7 lbs.
6
Force “C” = 1,000 lbs. x 2 = 333.3 lbs.
