ROBA®-duplostop®

The double safety brake system for elevator drives

Performance characteristics

Highest safety due to two independent brakes according to EN 81

Permitted for use with release monitoring as protection against excessive speeds in an upwards direction

Particularly short construction form

Cost-effective redundant elevator brake

Brakes can be switches and inspected individually

Prototype-inspected acc. ABV 766/1 Encoder can be mounted without increasing construction length

Simple installation

No air gap adjustment required

Extremely quiet operation due to may/^-patented sound damping

Brake can be opened via hand release
