Through The Floor Application
(For through the floor applications add these important dimensions to those above.)


Where to Begin?
When considering a floor to floor/incline belt conveyor, the most often asked question is, "Where do I begin?".

Well here we go.

1) Gather information on all products that will travel on the conveyor.

2) Determine your Conveyor Slope.

3) Determine your Net Lift.

4) Determine your Bed length and Total Length.

5) Determine the allocation of Total Length between Top Length and Bottom Length.

6) Determine your belt and frame width.

7) Determine your capacity requirements.


1) Gather Information
Gathering the correct information on all products that will travel on your proposed floor to floor/incline belt conveyor is crucial to a successful design. The following is a list of the information that needs to be gathered in this step.

a) Box Width

b) Box Length

c) Box Height

d) Box Weight

e) Balanced or Unbalanced Load

f) Figure "Box Ratio" (box length divided by box height)

g) Figure Box "Weight Per Foot" ({box length divided by 12} times box weight)

Pre-Designed PDF Information Sheet


How you place a box on the floor to floor/incline belt conveyor determines how the box is to be measured. Use the drawing above for guidance and measure all boxes accordingly.


In this step boxes with unbalanced loads must be identified. A simple test that can be performed on your boxes is the “Edge of Table Test”.

On any level table, cabinet, workbench etc. extend exactly ½ of the box length off the edge of your table, then rotate the box 180 degrees (without lifting the box) and extend the other end of the box, exactly ½ of the box length, off the edge.

If the box wants to tip from both ends of the box, it is balanced.

If one side wants to tip and the other side does not tip than the box is unbalanced.

Identify all unbalanced boxes and set them aside for further testing.

2) Determine Conveyor Slope
When determining your working conveyor slope you want to find the highest slope you can use that works with all your products traveling on your floor to floor/incline belt conveyor. This is usually determined by the "Box Tipping Diagram" shown bellow. This method is accurate but cumbersome, with this method you have to create a drawing to get your answers.

We have come up with the "Box Ratio" method. The method is mathematically linked to the "Box Tipping Diagram".



The "Product Tipping Diagram" can be used to check if a box will tip based on the conveyor slope.

1) Divide the box length into thirds, draw lines.
2) Draw lines from diagonal corner to diagonal corner, creating center point.
3) Rotate the box drawing to the desired slope.
4) Draw a line from the center of the box straight down. If this line stays in the center third of the box as it passes thru the bottom this box will work with this slope. If the line falls outside of the center third of the box it will tip.
(In the above case the conveyor slope would have to be lowered to accommodate "Box 2".)

Note: This method only works for boxes that have a evenly balanced load. For boxes with unbalanced loads further consideration is required.
"Box Ratio" Method


This is another method to check for box tipping that uses the ratio between the box length and the box height. This method is based on the above "Box Tipping Diagram" but does not involve any drawing.

1) Divide the length of the box by the height of the box, this will give you the “Box Ratio”.

2) Check the Chart below, find the highest “Box Ratio” that is lower than your box's “Box Ratio” and your box will work with that slope or any slope that is less.

3) When dealing with multiple boxes the box with the lowest "Box Ratio" will be used to determine the slope of your floor to floor/incline belt conveyor.
"Box Ratio" Chart
Slope "Box Ratio" Slope "Box Ratio"
30 Degree 1.7320 19 Degree 1.0329
29 Degree 1.6629 18 Degree .97475
28 Degree 1.5951 17 Degree 0.9172
27 Degree 1.5285 16 Degree 0.8602
26 Degree 1.4632 15 Degree 0.8038
25 Degree 1.3989 14 Degree 0.7479
24 Degree 1.3356 13 Degree 0.6926
23 Degree 1.2734 12 Degree 0.6376
22 Degree 1.2120 11 Degree 0.5831
21 Degree 1.1516 10 Degree 0.5289
20 Degree 1.0919 9 Degree 0.4751
In the "Box Tipping Diagram" from above there were two boxes.

Box 1: 18" long x 9" high

Box 2: 9" long x 9" high

Using the "Box Ratio" Method (box length divided by box height)

Box 1 has a "Box Ratio" of 2.000 (18" divided by 9")

Box 2 has a "Box Ratio" of 1.000 (9" divided by 9")

Using the "Box Ratio" 1.000 which is the lower of the two "Box Ratios". We find from the above "Box Ratio" chart that a 18 degree slope is indicated.

If these two boxes were the only boxes to travel on your floor to floor/incline conveyor than your conveyor slope would be 18 degrees or less.

3) Determine Net Lift
The net lift is the difference between (A) & (B):

(A) Top Height

(B) Bottom Height


In this example (print below) we have two floor levels that have a 6'-2" height differential. If we want to load and/or unload our boxes at the height of 36" on both floors then the conveyor net lift would be 6'2".



4) Determine Bed Length and Horizontal Length
The bed length and horizontal length is a function of, and based on, the conveyor slope and net lift requird.

In the previous steps we determined that the slope required was 18 degrees and the net lift required was 6'-2".

Using the "Bed Length Chart" below we find that a conveyor with a 18 degree slope and 6-2" of net lift would have a 18' bed length and a 22'-3" horizontal length.

Note: To use the "Bed Length Chart" below find your slope at the top of the chart and follow it down until the net lift is equal to or greater than your net lift, look to the left of the chart to see your bed length and click on the appropriate net lift to open a print which will show the horizontal length.
