Front Mount Dump Body Cylinder Force and Stroke Calculations

 
 2 Easy Steps for Front Mount Dump Body Cylinder Force and Stroke Calculations

4000 Series
Determine cylinder force needed.
This is the initial force needed to lift a load.

Approx. initial             Load (LBS.) x "A"
cylinder force      =                 "B"

Example

45,000# x 80"     =     22,500# of force
160"                               to start the lift.

NOTE: For a good design, the pressure on the
first ram at the start of the lift should not exceed 800 P.S.I.

4000 Series
Determine cylinder stroke needed.

The tables and formula below will give you the
required cylinder stroke for a dump angle.

Approx. Stroke = "B" x "D"

Example: 160" (B) x .845 (D) = 135" stroke


unit of measure = inches

A = Center of load to dump body
hinge (in inches)

B = Length in inches, cylinder base
pin to body hinge pin

C = Stroke

D = Dump angle

E = Center of load

F = Hinge
