Title: MECHANICAL BRAKE INTERRUPTER DEVICE
Abstract:
A mechanical brake interrupter for a lift or other similar suspended platform allows for stopping an emergency controlled descent during a power outage when an obstruction is present below. The mechanical brake interrupter includes a manual brake handle, a control collar, a coupling member, and an activation lever. The manual brake handle is used to manipulate a brake line for performing an emergency controlled descent. The coupling member is slidably connected to the control collar, and the activation lever is used to releasably lock the control collar in an armed position and unlock the control collar in an activated position. Rotating the control collar correspondingly rotates the coupling member such that the manual brake handle selectively engages the coupling member when the control collar is in the armed position, and the manual brake handle does not selectively engage the coupling member when the control collar is in the activated position.
