Safety Integrity Level (SIL) 3 certification from the International Electrical Commission (IEC) has been achieved for electric motors and large drive systems company Innomotics’ and mechanical engineering company OLKO-Maschinentechnik’s COBRA 02 S multichannel-controlled mine winder braking system.

Offering higher levels of safety for mine winder operations, the SIL 3 compliant COBRA 02 S features a number of failsafe components.

The COBRA 02 S ensures precise, delay-regulated braking independent of the winder’s operational state. Its multi-channel capability is customised to each unique application, allowing for a controlled and consistent stop under all circumstances, the companies claim in a statement.

The COBRA 02 S integrates 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 novel technology achieved SIL 3 certification in line with the requirements of the IEC EN 61508 and IEC EN 62061, validated by TÜV Süd in Germany, ensuring enhanced 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. 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.

“As the demand for safety in mining operations continues to rise, OLKO and Innomotics are reinforcing their commitment to excellence and innovation in mine winder technology,” says Innomotics senior sales manager Bernd Erdtmann.
