Abstract:
The present disclosure relates generally to a selectively operable safety brake including a magnetic brake operably coupled to a rod and disposed adjacent to a metal component, the magnetic brake configured to move between an engaging position and a non-engaging position, said magnetic brake, when in the engaging position contemporaneously with motion of the machine, moving the rod in to thereby move the safety brake from the non-braking state into the braking state, and an electromagnetic component including a retention apparatus, the electromagnetic component configured to move the magnetic brake from the engaging position to the non-engaging position upon receipt of a resetting signal.
