Lowering device

In one implementation, an electrically-actuated brake assembly is configured to control a rate of descent of an object to be lowered and includes: one or more rotatable surfaces coupled to the object to be lowered; one or more stationary surfaces configured to releasably engage the one or more rotat...

Beschreibung
Zusammenfassung:	In one implementation, an electrically-actuated brake assembly is configured to control a rate of descent of an object to be lowered and includes: one or more rotatable surfaces coupled to the object to be lowered; one or more stationary surfaces configured to releasably engage the one or more rotatable surfaces; an electric actuator system configured to selectively disengage the one or more stationary surfaces from the one or more rotatable surfaces, thus allowing the one or more rotatable surfaces to rotate with respect to the one or more stationary surfaces and enable the object to be lowered; and a rechargeable power source electrically coupled to the electric actuator system and configured to provide electrical energy to the electric actuator system.
