CONVEYOR BASICS
WHAT IS A GRAVITY CONVEYOR?A gravity conveyor moves objects without motor power. To help objects move "easier" . . . and with as little slant or slope as possible -
WHEEL CONVEYORS
In the drawing above, the axles are on 3 in. centers (also available in 1-1/2 in. centers). The number of wheels on each axle can vary. This determines the number of wheels per foot on the conveyor. BUT . . There should always be a minimum of 10 wheels under a box.
This helps you decide the number of wheels per foot to order. ROLLER CONVEYORS
The rollers are put in the frame as close together -
or as far apart as necessary . . . BUT there should always be THREE (3) rollers under the box.
LESS THAN 3 ROLLERS . . . box tumbles
BEST-3 ROLLERS UNDER BOX AT ALL TIMES! This determines the ROLLER CENTERS to order. MOVE THESE ON WHEEL CONVEYORS(Any items with a smooth, flat bottom. These items can be wider than the conveyor, 6 in. over on each side is not too much. Extra wide items like plywood, can be moved O.K., but center it carefully.)
MOVE THESE ON ROLLER CONVEYORSAny Items with an uneven or open bottom, or with a rim on the bottom. These items should never be bigger around than the rollers are long. HOW GRAVITY CONVEYORS ARE SET UP1. ALL SECTIONS HAVE COUPLINGS
Sections can then be used together by coupling them to each other. 2. PORTABLE SET-UP USS TRIPOD STANDS
Always use one more stand than the number of conveyor sections (3 sections use 4 stands.) 3. PERMANENT SET-UP USES STATIONARY SUPPORTS
Always use one more support than the number of conveyor sections (3 sections use 4 supports.) POWERED AND GRAVITY CONVEYORS CAN BE USED TOGETHER!This is called a "Flow System".
