Conveyor belt sag also referred to as catenary sag, is based on standard catenary theory. Sag is expressed as the percentage height drop based on the tension between two conveyor idlers. These percentages are expressed as limits to this height drop, and thereby define the minimum allowable tension, during the applicable running condition, at ...

The reputed belt maker USA literature states that for belt conveyor concave curve; the difference between circular arc curve and actual catenary curve is small. Thus the circular arc is engineering purpose catenary shape / curve. Also belt conveyors are being constructed by considering circular arc since very long time.

Although the belt tension required to start an empty belt is smaller than for a full belt, "chain theory" states that an empty belt catenary will be very flat (for a given belt tension) because the radius of the catenary is inversely proportional to the weight of the belt (i.e. chain).
