▶ Base belt

Sidewall belts require a certain tensile strength and abrasion resistance. For belt must have enough cross rigidity and ﬂexibility longitudinally to meet up with the requirement of deflection part of conveyor. The specially designed base belt with cross rigidity solved the problem of belt deformation. The belt standards are in accordance with international standards

QXE

This belt incorporates the transverse polyester monofilament cords within the fabric, used for small and medium sized applications.

QXE+2

The cross rigid and tensioning plies are separate, in this case the belt has 2 cross-rigid polyester monofilament plies, application areas are medium to heavy.

QXE-SC+2

This belt incorporates textile tensioning plies with Bekaert steel breaker. The high transverse stiffness means the belt can be used in application areas where rigidity is a crucial factor, i.e. High lift heights and wide belts.

QXST-SC*

This belt incorporates steel cord tensioning with Bekaert steel breaker. High tensile strengths can be achieved making the belt ideal for high vertical lift applications

Fabric reinforcement

QBF sidewalls from type S120/MDSF120 and higher have special diagonal fabric reinforcement in the corrugations as standard, smaller sidewalls can have this feature if required.

▶ Cleat

QBF cleats have been speciﬁcally design to give optimum performance.

The shape of the ‘C’ and ‘TC’ types has been created to offer the best conveying capacities along with excellent self-cleaning properties.

QBF cleats are molded with features of strong stiffness abrasion resistant and impact resistance to give the best shape retention even when conveying high-density materials.

Side blinker

Side blinker can be ﬁtted in between the cross cleats proﬁle and the sidewall to make a seal.

Side blinker is used when the material is particularly free flowing.

Hot vulcanization

QBF sidewall belting is assembled by hot vulcanization technology,

Which achieves super high adhesion value, non-fall off.

The adhesion won’t be influenced by high temperature material.

Automatic buffing machines present excellent adhesion value to ensure excellent adhesive strength.

Automatic cutting machines give accurate dimensions to ensure accurate specifications.

All QBF base belts, sidewalls and cleats are processed by our patent automatic machines.

Advanced computerised belt selection program

The appropriate belt speciﬁcation can be designed through specialized belt selection program by our experienced team based on data of conveying application.

Please send us an enquiry, we will be pleased to select an optimum belt along with our commercial offer.
