A braking device for an elevated platform assembly comprising a platform moveable along a generally vertical mast supporting an upright rack comprises an input gear assembly in mating engagement with the rack, a centrifugal actuator communicating with the input assembly and a spring-loaded brake responsive to the centrifugal actuator. The spring-loaded brake engages the rack and arrests the platform when the platform descends the mast at a rate above an upper threshold limit.
