There really are not too many features on conveyors. They are simple but highly effective. The rollers may have ball bearings in them to help them roll smoothly. Some of the conveyors that are electronically controlled rather than manually will have on and off switches, which are simple to use. The size of the conveyor is something else that can vary quite a bit. Different sizes may appeal more to some users than to others.
The conveyor system is very simple. It is a long table at its most basic level. Those who use the conveyor will place items on one end, and then they can push or roll them down to the other end. Many of the conveyors have rollers on them to make the task of moving even heavy items very easy. Others are automatic, or have a button that can turn them on and off, as you see in the grocery store. They help to make work faster and easier, and for that reason, they are a big part of many industries today.
