BRUbelt ®

Flat, high strength belts for materials handling, lifting equipment and drives.

What is BRUbelt?

Whether for material handling equipment, elevators or conveyors – the BRUbelt is defined by maximum dynamic strength and is available in customized designs.

BRUbelt is the combination of high strength steel strands and high tech polymers that allows the creation of the innovative drive systems in the smallest possible space.
Compared to conventional steel cables, BRUbelt offers higher load-bearing capacity with a reduced metallic cross-section. BRUbelts cover a very wide range of different applications. As an alternative to chains and wire rope hoist systems, they offer the user a maintenance-free, cost and space saving solution for the respective area of application.

What is the structure of BRUbelt?

BRUbelt provides you with low noise, high strength flat belts for various in confined spaces. This product is used. In the areas of lifting equipment, conveyor technology, industrial doors and lift systems in warehouse logistics.

BRUbelt end fasteners

With the Brubelt end connector there is no reduction of the minimum breaking load. In addition, customized end fasteners are created upon request.

The flat belts made of steel cords sheathed with thermoplastic polyurethane do not require lubrication, but run grease-free on the pulleys, which significantly reduces maintenance costs.

Compared to wire ropes, BRUbelt flat belts cause considerably less wear on belts, idler pulleys and drive pulleys, which also has a positive effect on maintenance costs.

The belt itself has three times the service life of classic steel cables. With a wrap drive, the drive motor can be mounted close to the ground and is therefore easily accessible. The BRUbelt is also used as a traction drive, thanks to the frictional properties of the coating, the BRUbelt can be used with the smallest possible drive pulleys.

BRUbelt flat belts save space

The high flexibility of BRUbelt flat belts in combination with their flat shape allow smaller sizes of the entire installation. Both the idler pulleys as well as the gearboxes and motors can be selected to be significantly smaller.

Also, depending on the design, a single small deflection pulley is sufficient.
This advantage enables up to 50% space savings and allows a higher lifting height and thus additional available storage capacity or perfectly exploits a low hall height in confined spaces.

An overview  of the flat belts

The table below gives you an insight into our product portfolio. However, our strength also lies in developing specific designs in cooperation with our customers. Depending on the application, we can also integrate copper or fiber optic cables into the flat belts in addition to the steel cables (BRUbelt Hybrid).

The right scope of application

Whether in the warehouse or the production hall – the flat belts can be used in their standard temperature range from – 20°C to + 60°C and behave in a non-condensing manner up to a relative humidity of up to 80%. However, the exact limits of use depend on the particular load case. Higher or lower temperature ranges can be accommodated in customer-specific designs.
