| GENERAL |
TABLE
I |
Since many sections and accessories
may be coupled to one drive, it is important that the motor be properly sized for each application.
Table I (at right) may be used as a general guide to selection of drive motor sizes for typical installations.
When powered accessories are added to straight sections, the maximum allowable length must be adjusted. Table II (below) lists the horsepower required for
various accessories.
Factors that are important to power requirements include the number of rollers per foot, the total length of
straight sections, the number and type of powered accessories and the desired speed of the conveyor.

CAPACITY
The drive capacity accepted is 15 lbs.
per roller. The type of package and/or material being conveyed may increase or decrease this capacity. Very hard, rigid, flat bottom containers increase roller capacity while soft, uneven surfaces will decrease it.
NOTE: Drive capacity for model 138LS is 10 lbs. per roller; 7.5 lbs. roller capacity for model 138LSC.
|
ROLLER
CENTERS
The number of rollers required per
package is dependent upon package weight, package length, drive capacity per roller, and type of surface. The
package formulas (at right) should be used to determine the maximum allowable roller centers. Use the lesser
of the two values rounded to the nearest standard roller centers. Finally, only use model 138LS for light duty applications where close roller centers are required. |
