Electrically driven set and release hand brake for rail cars

摘要

An apparatus for a hand brake includes a gear assembly, an electric motor coupled to the gear assembly, one or more sensors configured to sense at least one of the released and set states, a controller coupled to the electric motor and to the one or more sensors, the controller is configured to operate the electric motor in accordance with a predetermined logic algorithm so as to move the chain between the released and set states, and a device being movable between a first position wherein the device engages only the hand wheel and wherein the hand wheel is used to move the chain between the released and set states and a second position wherein the device engages both the hand wheel and a gear in the gear assembly and wherein the electric motor is operable to move the chain between the released and set states.
