Conveyor Calculation and Design
In order to obtain the final operation design, it is necessary to perform the following steps:
Step #1 - Drawing
It is important,
regardless of whether the calculations are being made by the user, sales
engineer or factory, that complete information is available. The following list
covers factors commonly necessary to consider when calculating line pull, which
is the first step in the selection and location of the drive.
weight to be transported on a single trolley.
Generally it is
desirable to have the drive located at the highest point in a system sp that a
declining curve (if Multiplan system) is on the slack side of the drive. On
monoplane systems the drive unit should be placed “downstream” of the off
Another good general rule to follow is to locate the drive so as to utilize a 180º curve, if possible and practical. In a relatively short and lightly loaded system this is not too important. However, it is always desirable to have as many driving lugs engaged in the drive sprocket at one time as possible.
only partial credit has been taken for the loads on the decline, the other
portion has not been ignored. To simplify the calculations, we have not
requested the additional line pull percentages due to negotiating vertical
curves without sprockets and horizontal curves with sprockets. These additions
have been taken care of in our general line pull calculation formula.
are many other things to take into consideration when analyzing a conveyor
application: Overloading, loading on inclines contrary to specifications,
unloading declines contrary to specifications, no lubrication contrary to
instructions. Don’t forget that many conveyors are used for storage, even
though not originally purchased for such purpose, and as a result are, many
times, fully loaded while the original intent was to have them only partially
loaded. This statement is made only for the purpose of impressing on the mind of
the individual the necessity of carefully reviewing all the facts when
calculating a cable conveyor system.
