Description

Overview
  • The INTORQ BFK455 is an electromagnetically released double spring-applied brake with two separate brake circuits. It is designed for redundant safety braking and is especially suitable for elevator and stage technology, where one brake circuit alone can provide the required braking torque.

Advantages
  • Two electrically and mechanically separate brake circuits
  • High redundancy for safety-relevant applications
  • Each brake circuit can be controlled separately
  • Microswitch for function monitoring of each brake circuit
  • Long-term stable noise damping
  • Flat design for compact integration
  • Type-tested according to EN 81-20 / EN 81-50

Application Areas
  • Elevator technology
  • Stage technology
  • Platforms
  • Cranes and hoists
  • Industrial applications with redundant braking function

Key Technical Data
