One of the most common conveyor system problems is the belt running off the track. This can halt operations altogether and impact productivity. 

The slightest external factors can cause belt tracking problems, including debris between the belt and the pulley, off-center loading of goods, belt distortion and goods exceeding the weight specifications of the conveyor system.

If belt tracking problems occur frequently, it can be a sign that one or both pulleys are not positioned properly. Most belt tracking issues can be solved by adjusting pulleys and rollers or improving the design of the system with the right conveyor belt parts and accessories.

Here are three of the most common belt tracking problems and recommended solutions:

1. The belt runs off to the same side

Conveyor belts typically run off to the side with the least tension when there is a tracking problem. 

Conveyor systems with a fabric belt are equipped with at least one cylindrical pulley that stabilizes the belt and allows it to run straight. Still, for applications requiring several belt path redirections or a side feed, additional belt tracking measures such as a guide roller are needed.

2. Material buildup

Material buildup is one of the most common reasons for conveyor belt tracking problems. 

Carryback, or the material left on the belt after discharge, can lead to excess debris and dirt. This can wear belts down faster, cause damage to other components and lead to belt tracking problems. 

To prevent this, belt cleaners can be installed on either the head or tail pulley – or both. Belt cleaners ride against the belt to dislodge material and reduce the amount of buildup on belts.

3. Visible signs of damage

Belt tracking problems can be caused by excessive wear and tear on belts. 

Visible signs of damage are fraying edges, rips, tears and folds that affect operations. In this case, belts need to be replaced. Keep in mind, though, that any damage to conveyor belts affects the system’s components – including the idlers.
