Chain Feeding System
Calculating the Load of the Entire System on the Structure
For calculating the load of the entire Chain Feeder System on the structure identify the following factors:
(1) The weight of suspended hoppers (use formula from
for calculations), (2) The length of trough
to be suspended, (3) The number of corners to be suspended, (4) The number of direct drive units to
be suspended.
Tabulate the weight of the Chain Feeding System to be suspended by inserting the quantity of each
component in the formula below.
HW
= Weight of hopper to be suspended (calculate weight using previous formula)
N
= Number of hoppers to be suspended
L
= Length of trough (in feet)
C
= Number of corners
D
= Number of single drive units
(

C*
22.759) + (
D*

Weight of entire Chain Feeding System on the
Structure (pounds).
NOTE:
If more than one type of hopper is used in a structure, each hopper weight must be calculated and
inserted into the formula for entire weight of the Chain Feeding System.
NOTE:
Weight of feed calculated at 40 pounds per cubic foot. If feed to be used is a different density, the
weight of the system must be adjusted accordingly.

T = Weight of trough per foot
C = Weight of chain per foot
F = Weight of feed per foot of trough
G = Weight of grill per foot
CU = Weight of coupler per foot of trough
Weight of trough per foot = T+C+F+G+CU*1.25
