Could you please clarify what assistance is required? It is not clear to me at least.

As you state there are various causes and rectifications, if you go for a search on this site there may be results from previous queries which may be of interest / use.

I am not aware of any standard to which the devices are designed / manufactured (other than the "generic" mechanical / structural codes), though I suspect a lot of it is emperical.

Have a romp on google. Here is one manufacturer to get you started:

There are others.

I apologise, however I do not believe I completely understand the query.

Can you please clarify exactly what you would like additional information on?

Thanks and regards,

i have found that counterweight masses have a direct impact on the tracking characteristics of conveyors, depending on the type of construction of the frame, and loading of the belt. i currently play "doctor" to a large amount of conveyors, and must admit to varying degrees of success with tracking etc. however, there is one constant,,,,,,,,,,,,,, check the design calcs, and also consider any modifications added after construction ie ceramic drive drum lagging. ■

If the system is designed and installed “appropriately” then ideally there should not be any significant force tending to “miss-track” it.

I am not aware of any rigid classifications of the causes of miss tracking (there may be).

You ideally need to find and remove the cause of its miss tracking (poor alignment, worn pulleys, sized something’s or others, defective belting etc) and fix (ideally) or counter it.

A number of installations use the training idler assemblies, similar to that I linked earlier, or “rotate” idler sets to track the belt.

Place a pencil on the table and roll it on the table with your hand on top, now angle the pencil and note how your you hand tracks off “aligning” with the pencil, this could be considered an analogy to the belt and idlers, where the belt is your hand and the idlers are the pencil, hence you can “rotate” idlers to track the belt in a direction (probably opposite to the way it is off tracking). This “solution” wears belt and idler and increases frictional losses etc. There are other mechanisms often included within the training assembly which are purported to improve tracking effectiveness.
