摘要：
An elevator safety device in which a counterweight cam is attached to the counterweight and top terminal landing final limit switches are disposed below the bottom terminal landing of the hoistway so that it is operated by the counterweight cam. The top terminal landing final limit switches only need to be provided in accordance with the counterweight buffer stroke, regardless of to what extent the car has been flung upward, with the result that fewer final limit switches are required.
