Slip-free elastic monolithic conveyor belts

The positive driven AT5 conveyor belts from BEHAbelt enable slip-free traction, even with the smallest pulley diameters of only Ø 18 mm. This means that even conveyor sections with the smallest transfers can now be utilized with a slip-free belt solution.

In combination with a maximum belt width of up to 700 mm, the new product series from BEHAbelt represents a new product solution which once again shifts the previous limits of the possible applications of positive-driven belt solutions on the market.

This makes the positive driven conveyors perfect for applications that require precise timing, positioning and reversing. The low preload minimises the bearing load and thus reduces the energy requirement as well as the maintenance effort.

Functional conveyor belt surfaces

BEHAbelt already offers a wide variety of functional belt surfaces in this product category. Due to our close contact with machinery engineers and end users, we have continuously expanded and adapted our belt surfaces to optimally convey greasy, moist, dry or frozen products.

All belts are available in usable widths of up to 700 mm and are monolithically manufactured in a 2-component process.

For high hygienic requirements

The completely monolithic construction of the conveyor belts without aramid strands or fabric layers offers an optimal ­hygienic belt design which meets the highest requirements in the food industry according to HACCP and offers a preventive hygienic machine design.
Thanks to a careful selection of raw materials for direct food contact, the belt solutions offer very good microbial, hydrolysis and chemical resistance.

Concepts for belt tracking with AT5 belts

The AT5 belts can be used in different belt drive concepts. While the drive drum is mostly effective using the AT5 or T5, pulleys are often designed cylindrically smooth with a suitable guide shape.

Precisely because of the flexibility of the slip-free belts, very small pulleys can be designed at the drive and idler pulley, which, in addition to cost savings or conversion of the motor and drive concepts, may also require less installation space and allow better accessibility to the system parts.

Concepts for belt tracking

Design standards simplify belt configuration

The slip-free belts from BEHAbelt allow a process-safe application, thanks to a standardised pretension recommendation for all belt widths and belt designs. The low pretension of only 1.5% ±0.5% enables easy installation and also reduces the bearing load and heat development in rolling nose bar (usually made of plastic).
For the operation of the elastic belts we recommend to use AT5 pulleys to allow a maximum range of application; T5 pulleys can also be used under certain conditions.

Replacement of T5 timing belts with Aramid and steel reinforcement

Thanks to the belt width of up to 700 mm, multiple belt strands designs can be replaced by one belt, which represents hygienic improvement and simplifies the design of the systems.
Particularly for light and medium loads, timing belt solutions can be replaced, which were previously used as ­“conveyor belts”. Consult your BEHA representative for assistance.

Suitable applications for AT5 belts

Due to the elastic monolithic belt construction, the use of the belts is essentially recommended for small and medium weights. Wherever precise timing, positioning and reversing is required, this belt solution is an great alternative and product solution.

Welding technology for monolithic elastic conveyor belts

Simple butt welding is enough: Elastic monolithic PU conveyor belts from BEHAbelt offer new fabrica- tion possibilities. Due to the lack of traction layers joining by finger welding is no longer necessary, as the monolithic belt has a homogeneous design – even in the weld seam.

Welding device HS400 & 800:: The welding device HS from BEHAbelt is a simple, handy, reliable and cost-effective tool for butt splicing of monolithic belts (up to 800mm width).

Precision: The adapter plates, specially designed for the AT5 pitch, ensure precise positioning and clamping of the belt ends to be welded.
