And, be used to detect governor 4 that whether lift car 1 exceed the speed limit and be arranged on parts 81 on the top of hoist trunk 10 by guide rail 8 supportings, hoist trunk below be provided with the pulley 41 that is used to produce tension force.This governor 4 is connected with rope 42 by governor with pulley 41, and also is connected with lift car 1 by link 51.Promptly, when moving along with lift car 1, governor 4 rotation and when reaching abnormal speed, hoist cable clamping device 43 actions of governor 4 also hold on to governor rope 42, link 51 via lift car 1 mechanically makes emergency braking apparatus 5 actions, produces huge friction force so that lift car 1 stops on guide rail 8.
In addition, rope sheave 62 is installed on the winch 6, the friction-driven between its dependence and the hoist cable 3 drives elevator.In addition, be provided with the coder 61 that is used to measure winch 6 rotating speeds in winch 6, it can detect the speed and the location information of elevator.Control setup 7 with microcomputer accepts to come from the position signal and the speed signal of this coder 61, and winch 6 is controlled.
And, be provided with buzzer phone 9 as notifying device in the lift car 1, in emergency braking tests, when idle running appears in rope sheave 62, by these buzzer phone 9 notices idle running has appearred.And buzzer phone does not need to be provided with separately, and the buzzer phone that can utilize lift car 1 overload warning to use, and makes this buzzer phone send the different sound of chimes of doom when overloading, for example interrupted chimes of doom when idle running takes place rope sheave 62.
At this, as the notifying device of notice rope sheave idle running, except sound generating apparatus such as buzzer phone, also can be to accept to be arranged near the signal that camera head sent of winch, and with its device of notifying as graphicinformation.In addition, the demonstration that also can adopt near top 20 indicating device and the telltale on the operation board in the lift car 1 to carry out rope sheave idle running.
