OLKO & Innomotics achieve SIL3 certification for winder braking system
Thyssen Schachtbau member company OLKO-Maschinentechnik GmbH, a globally leading provider of shaft hoisting technology, and Innomotics, have achieved SIL3 certification for their COBRA 02 S braking system for mine winder installations.
The COBRA 02 S multi-channel-controlled safety braking system they state“ integrates seamlessly with the Innomotics winder controller, which is already SIL 3 certified, enhancing operational safety.”
This comprehensive braking system addresses both hydraulic and electrical control functionalities, enabling its application across all types of mine winder machines. This cutting-edge technology has achieved SIL 3 certification per IEC EN 61508 and IEC EN 62061, validated by TÜV Süd in Germany, ensuring highest safety for mine winder operations.
One of the standout features of the COBRA 02 S is its electro-hydraulic brake control system, which ensures constant deceleration under any conditions. Whether facing varying load levels, changing movement directions, or friction-related fluctuations during safety mode activation, the system guarantees a preset, steady deceleration to safely halt the winder.
To achieve the stringent SIL 3 certification, a significant number of fail-safe components were incorporated. The COBRA 02 S

ensures precise, delay-regulated braking independent of the winder’ s operational state. Its multi-channel capability is tailored to each unique application, allowing for a controlled and consistent stop under all circumstances.
The statement concludes:“ After many decades of working together in mine winder installations around the world, OLKO and Innomotics have developed the multi-channel-controlled braking system, intensifying their cooperation and partnership. Both companies are pioneers in developing innovative mine technologies.”
Mine winding systems vary significantly based on shaft depth, payload, and operational needs. Becker designs rope attachments for drum winders, friction( Koepe) winders, Blair Multi-Rope configurations, guide rope installations, as well as rope maintenance and handling equipment.
These winders support a wide range of operations, from transporting personnel and materials to hoisting ore.“ Regardless of application, Becker’ s rope attachments are designed to integrate seamlessly, maximising performance and reliability.”
It adds:“ No two mines are alike, and neither are their attachment requirements. Our inhouse engineering teams leverage decades of experience to develop
