Chainless How to Specify Curves

When specifying curves, list the curve radius, degree of curve and type of curve (Horizontal or Vertical -- Top or Bottom).
From the table below select the curve length for the specified curves. This information is necessary to calculate the conveyor overall length, and the maximum line pull.

R= Radius
D= Degree of curve
C= Radius of curve
P= Depth of curve
R D C P
3’ 0” 30º 1’  6 7/8” 4  13/16”
4’ 0” 30º 2’ 11/8”  6  7/16
5’ 0” 30º  2’  7 7/16” 8  1/16” 
3’ 0” 45º 2’  4 1/4” 10  9/16”
4’ 0” 45º 3’  1 11/16”  1’ 5 9/16”
5’ 0” 45º 3’  1 11/8” 1’ 5 9/16”
3’ 0” 60º 3’  1 11/16” 1’ 6”
4’ 0” 60º 4’  2 1/4” 2’ 0”
5’ 0” 60º 5’ 2 13/16” 2’ 6”
3’ 0” 90º 4’ 8 9/16”
4’ 0” 90º 6’  33/8”
5’ 0” 90º 7’ 101/4”
