Abstract
An elevator governor inertia carrier has a cartridge having a shaft opening for receiving a shaft. The cartridge is configured for fixed attachment to the shaft. At least one force-exerting element is associated with the cartridge and has a hollow body with an internal cavity extending between a first open end and a second end, an elastically-resilient element retained within the internal cavity, and a contact member at least partially disposed within the internal cavity and in contact with an end of the elastically-resilient element. The contact member is retractable into the internal cavity to compress the elastically-resilient element when a force greater than a restoring force of the elastically-resilient element is applied to the contact member.
