Sidewall conveyor belts, also known as steep angle corrugated sidewall conveyor belts or skirted partition or cleated conveyor belts, are a type of specialized conveyor belt designed to address steep angle and vertical conveying applications. They are widely used in scenarios involving the continuous conveying of bulk materials at steep angles. These belts can operate stably within any angle range from 0° to 90°, achieving dual breakthroughs in conveying inclination and space utilization. They are particularly suitable for steep angle and vertical lifting conditions where traditional conveyor belts fall short.
The steep angle corrugated sidewall conveyor belt consists of three components: the base belt, sidewalls, and cross-ribs. The sidewalls are designed with a corrugated profile, while the cross-ribs feature T-shaped, C-shaped, or TC-shaped structures. The sidewalls and cross-ribs are bonded to the base belt through a secondary vulcanization process, ensuring high bonding strength.
Wide width sidewall conveyor belts are precision-engineered from three main components: the base belt, corrugated sidewalls, and cleats. This unique three-part structure forms a "box-shaped" conveying space, ensuring stable and controlled material transport during high-angle conveying.
The cleat is mounted vertically between the base belt and the side walls, forming a separate "pocket"-shaped compartment that supports the material; it is a key component for achieving high-angle conveying. The selection of the crossbar is determined by the conveying angle.

Cleat Types |
Applicable inclination angle |
Application Features |
|
T Shape |
18°~40° |
Suitable for conveying at small to medium angles of inclination, with low cleat height |
|
C Shape |
40°~60° |
Suitable for steep angle conveying, with superior material transportation capacity |
|
TC Shape |
60°~90° |
Suitable for extremely steep inclines and vertical conveying, as well as applications where the material being conveyed has good flowability |
|
Without cleat |
Below 18° |
In situations where the slope is gentle and materials are easy to transport, only sidewall is needed, the cleat can be moved. |

Based on the characteristics of your material and your specific conveying requirements, we can help to design the appropriate sidewall and cleat. |

Corrugated sidewalls are located on both sides of the base belt and are designed with a corrugated profile to facilitate wrapping around the drum. The primary function of the sidewalls is to prevent material from slipping and spilling out from the sides during conveyance. The height of the sidewalls can be flexibly selected from 40 mm to 630 mm based on the characteristics of the conveyed material and the conveying capacity.
