Abstract
The novel lift speed limiter is used to protect lift against the upper overspeed and/or down overspeed so as to ensure the safe running of lift. The novel lift speed limiter includes one speed limiter member similar to that in available technology and one increased friction pair set between the ratchet wheel of the speed limiter member and the frame. The increased friction pair provides the steel cable with tension or drawing force, so that the cable wheel and the steel cable produce no relative sliding, the cable groove is protected against wear and damage, and the drawing force is stabilized. The present invention has simple structure, low cost and high running safety and reliability.
