General Overview of the Coupling-Brake Systems TZS
The torsionally flexible, individually configurable Coupling-Brake Systems RINGFEDER® TZS – developed and continuously advanced from the industrial brake business of the former TÜSCHEN & ZIMMERMANN GMBH & CO. KG – combine the highest safety standards with innovative technology. Torsionally flexible, modular Coupling-Brake Systems equipped with robust RINGFEDER® Elastomer Couplings, ensuring highly reliable operation in mining and conveying applications such as chain and belt conveyors.
- Applications: Ideal for conveyor drives in underground and surface mining, heavy industry, plant engineering, and power transmission systems
- Two Brake System Options: Safe and controlled braking using either the fail-safe electromechanical brake TZF EL-SA or the manual clamping device TZC
- Structures: Highly flexible and customizable modular design including coupling, brake disc, brake unit, cover, and optional add-ons
- Excellent shock and vibration damping with compensation for axial, radial, and angular misalignment via the integrated elastomer jaw coupling
- Optional configuration with hydrodynamic coupling
- ATEX compliant according to 2014/34/EU and DIN EN ISO 80079-36:2016 for use in explosion-hazard areas
Classification of Coupling-Brake Systems
Users can choose between two different brake systems:
- Electromechanical Function Brake TZF EL-SA
- Manual Clamping Device TZC
The electromechanical function brake TZF EL-SA with fail-safe functionality is electrically actuated and enables controlled braking and holding based on the proven spring-applied principle.
The manual clamping device TZC is a hand-operated chain tensioning and locking mechanism for chain scraper conveyors and other drive and conveying systems.
