Chevron conveyor belts
Conveyor belts with a smooth carrying surface are useful for conveying of packed and unpacked material up to the angle of inclination 22° as an upper limit.
Chevron belts are the right belts to meet your requirements when higher angles of inclination are required. For this purpose, our experts have developed high-performance and high-quality Chevron and High-Chevron conveyor belts. They are noted for long service life and flexibility due to homogeneous Chevron profiles, which are vulcanised together with a base belt.

For this purpose, our experts have developed high-performance and high-quality Chevron and High-Chevron conveyor belts. They are noted for long service life and flexibility due to homogeneous Chevron profiles, which are vulcanised together with a base belt.
Chevron conveyor belts are suitable for:
- quarries, sandpits
- cement works, lime works
- farming: conveying of beets, grains, potatoes, fertilizers, wooden chips
- coal and coke transport
- sugar refineries
- salt mines
- mobile crushers and screens
- road milling machines
Selection of a profile type and height depends on the material to be conveyed and the angle of inclination:

The values given are just an orientation and depend on the type of goods conveyed, loading conditions and the conveyor belt speed.
The maximum inclination of a smooth conveyor belt ranges from 15° to 22° in dependence of the type of material.
Steep angle conveyor belts with a profiled surface reach an inclination of 30° to over 40°.
In unfavorable loading conditions only the profiled surface may be loaded. For the rest, the capacity is calculated in the same way as for smooth surface conveyor belts.

Chevron conveyor belts with A and AH type profiles
Type AF - profile height 32 mm
Being an expert producer of Chevron conveyor belts, Trelleborg is always striving to develop new cutting-edge technology to incorporate it in conveyor belts.
The existing 32 mm high F type Chevron belts have been recognized as one of the best in the industry and are regularly used in the most challenging working environments possible.
In order to provide you with even better Chevron belts, our engineers have utilized their knowledge and experience and developed a new Chevron conveyor belt with the already known 32 mm profile height, but with a new, improved design for an even better performance on site. The name of the new profile is AF.
