Abstract:
An elevator electrical safety actuation system and method are provided. The system includes an actuation device configured to operate a brake device. The actuation device includes a locking mechanism (542), a first portion (534) configured to be engaged and retained by the locking mechanism (542) in a first portion-first state and moveable to a second state wherein the first portion is not retained by the locking mechanism (542), a second portion (536) in contact with the first portion (534) when the second portion (536) is in a second portion-first state and the first portion (534) is in the first portion-first state, the second portion (536) moveable to a second portion-second state, wherein the second portion (536) is operably connected to the brake device, and a resetting mechanism (546) configured to force the first portion (534) from the first portion-second state to the first portion-first state.
