Abstract
A frictionless electronic safety actuator (), for use in an elevator system, includes a magnetic plate (); an electromagnet (); a linkage (); a biasing arrangement (); and a path-constraining arrangement (). The linkage () is actuatable so as to move a safety brake () into frictional engagement with an elevator guide rail (). The linkage () is attached to the magnetic plate () and is moveable between a first position in which the linkage () is actuated and a second position in which the linkage () is not actuated. The biasing arrangement () is arranged to apply a biasing force to the magnetic plate () to bias the magnetic plate () towards the first position.
