Calculating Ram Travel for Bend Angle

After the conduit has been snugged up, the ram must travel a particular distance to achieve the desired bend angle
(Table 1). A rubber O-ring on the ram scale is used to indicate the position at which the bend angle is achieved. Use
the directions below to determine where to place the rubber O-ring on the ram scale.
1. Snug-up bender by advancing ram until shoe,
conduit, and follow bar are tight. The conduit should
not be able to twist between the saddle and shoe.
2. Calculate Z = X + Y
Z = Stop position on ram scale based on X and Y.
X = Scale reading at Snug-Up position.
Find X by looking where the scale and top of the
cylinder block meet.
Y = The Ram Travel from Table 1. This is how far the
ram should travel to achieve the desired bend
angle for a specific conduit size.
3.
Move rubber ring to calculated Z-Position. (Fig. 16)
4.
Advance ram to the Z-Position. Monitor the bend
and stop when the rubber ring touches the top of
the cylinder block. (Fig. 17)
*This table shows
the distance (Y) the
ram must travel
to make a bend.
