Conveyor Belt Maintenance & Common Conveyor Problems | …

Conveyor belts rely on a precise balance of tension to work correctly. If there is too much tension or too little, things begin to go awry, and the belt can slip. Specifically, if the head pulley breaks down or even becomes overly worn, there will no longer be enough tension to keep the belt from slipping around.

Optimizing Conveyor Take-up Systems using Dynamic Analysis ...

The function of a take-up is to control the belt tensions at the take-up pulley. The belt loading, thermal growth or reduction, and dynamic tension waves (during starting or stopping) cause variations in belt tensions during conveyor operation. Figure 2 shows a schematic of two simple conveyors. One has a
