The surface of some conveying systems incorporates a V-shaped or angled configuration of raised ribs. This design promotes enhanced material retention, particularly on inclines. For instance, transporting loose aggregates up a steep slope benefits greatly from the grip provided by the angled cleats.
This type of belt construction offers advantages over smooth surfaces in terms of preventing slippage and increasing the volume of material transported. Its origins lie in industries seeking more efficient methods for handling bulk goods at elevated angles, ultimately leading to increased productivity and reduced material wastage.
