The ROBA® duplostop® is a noise-damped, redundant dual circuit brake for compact elevator machines in which both brake circuits clamp a rotor together. In contrast to the ROBA® twinstop®, each brake circuit is housed in a separate coil carrier. As a standard-compliant braking solution, the ROBA® duplostop® meets in particular the requirements of the Chinese market.
