Customer-specific solutions for tire and rubber technology

Rexroth offers a comprehensive range of products and application expertise for use in tire and rubber technology

- Safety Brake- and Holding System SBS

- Hägglunds direct drive systems, including the Hägglunds CB 280 motor

Thanks to its worldwide application expertise and comprehensive research and development activities, Rexroth supports the tire and rubber industry with industry-tailored system solutions. Safety solutions, especially in reference to tire handling, become more and more important in this industry. Based on this background, Rexroth developed the safe braking and holding system SBS for tire handling for reliable drop protection for vertical axes. The compact Hägglunds CB motor range is part of the reliable Hägglunds drive systems that long have been used in the rubber industry. Thanks to its heavy-duty design the motors can even take sector specific shock loads and stop instantly when required. Thus they are suitable for many heavy-duty applications.

Safe braking and holding system SBS

With the safe braking and holding system provided in the frame of its IndraDrive drive series, Rexroth is the first drive manufacturer to offer an integrated system solution for drop protection for vertical axes. The system ensures that vertical axes come to a redundant stop even after energy has been switched off. In this way the solution assures a safe handling of tires.

The safe braking and holding system by the company Rexroth makes use of three independent channels: the drive control system in Rexroth IndraDrive, as well as two mechanical brakes. These two external brakes are only used when the power to the motor is switched off. They are controlled and monitored separately from the diversity channels in the drive. The concept can accommodate any electrically releasing brake type, including products by other manufacturers.

In case of failure an escalation strategy makes sure that the “safety related braked standstill“ is achieved with minimum strain on the mechanical system. In the first stage, the drive attempts to bring the vertical axes to standstill by means of a reset of the command value. Failing this, the two mechanical brakes will be activated consecutively or - in critical situations - simultaneously. The safe braking and holding system of Rexroth IndraDrive is certified in accordance with EN ISO 13849-1, category 3 PL d and EN 62061 SIL 2.

Hägglunds motor CB 280 motor for heavy-duty applications

Hägglunds reliable direct drive system comprises drive unit, motor and control system and have long been used for mixing room technology. Today the company has an increased scope and can supply solutions through-out the tire production line.

The Hägglunds CB motor range from Bosch Rexroth is suitable for many heavy-duty applications such as shredders or roll mills for the rubber industry. With their space saving design and the versatile mounting possibilities they give customers a high degree of freedom designing their own configuration. The wide range of sizes and displacements enables optimisation of the drive system when selecting the motor and the hydraulic pump combinations. The heavy duty design of the radial piston motors can even take shock loads and stop instantly when required.
