WRB1
- WRB 1 is acting in upward direction on suspension ropes
- Placed near traction sheave (on existing machine frame or on machine room floor)
- Brake force is generated by two spring-loaded brake plates
- High security factor as a result of additional mechanical release by bowden cable at the overspeed governor
- Less effort for control engineering to integrate the rope brake into lift system, because the reset to starting position doesn’t need an additional supervisioned device
- Very suitable for modernization of lifts
- Less effort for connection to lift controller
- Less effort for assembly and maintenance
- Fast and easy replacement of the brake linings
