Sizing a Spiral Step 2

Belt width selection is made by determining how the products will be loaded onto the spiral, what type of belt is being used and whether the spiral is an upgo or downgo.  For downgo spirals add 2" to the belt width for hold down rail.

Spiral Loading:

Belt Types:

Rod type belts: (Belt edges are typically not used for product loading)
Flex type grid belts: (Belt edges are usable for product loading)
Flex type plastic belts: (Belt edges are usable for product loading)

Hold Down Rails:

Hold down rails are commonly used on descending spirals and require and additional 2 inches of belt width.

Notes on Example:

In this example, a 38" wide belt could easily be used if you chose a flex or plastic belt.  A rod type belt would be more difficult, assuming a horizontal loading pattern.  A 40" wide rod type belt could be a good choice.  This example assumes and ascending spiral.
