8 tachometer generator with a chain, belt drive, a safety switch. Feedback voltage power failure, the elevator should stop immediately.
The 9 speed limiter adjustment parts of the seal in mind. Indicate the operating speed marked the security clamp action in response to the direction of rotation; governor every two years once Calibration Laboratory.
10 rated speed is greater than 1 m / s, the speed limiter should be a safety switch

Hoistway
11 upper and lower limit switches should be in good condition and should not be the upper and lower limit switch.
Limit switch is activated, the weight or the car with the buffer should not be in contact.
12 When the car, the weight completely indeed buffer, a further rail-guided itinerary must not be less than 0.1 +0.035 V ² (m) the requirements.
13 jiaoding should be located on the heavy side of the fence, the other side of the shaft wall spacing is greater than 300mm,
Set the fence.
14 traction wire rope force should be similar device the difference should meet <= 5%, the rope fastening should be reliable, the rope fastening plate should be firmly fixed and the traction rope should not be dead corner, twisted, broken wires, wear and tear.
15 jiaoding should be set can cut car operation and automatic switch circuit device for the repair operation, the push-button switch should be marked with their function names, the safety switch with a red flag.
16 When the car has a safety window car security window should be set to the safety switch.
17th floor door car under the door-side sill gap should be 4-8mm, should be firmly fixed layer door slider, slider should not prolapse sill chute.
18 door knife and door pulley depth of engagement should meet> = 5mm, runtime door knife and pulleys, door knife sill, pulley and car Hom should not collide.
19th floor doors should be set to direct electrical mechanical interlock, the depth of engagement should meet> = 7mm,
Side gap of 1-3mm, contact should be reliable, should be firmly fixed, the the passive door should switch.

Well Road car

20-storey open the door, under the state of emergency, the elevator should be <0.63 m / s inspection speed run
21 layers of the door should be set to the mechanical key to unlock the device, the action should be flexible and reliable.
21 car maximum effective area should meet GB7588 8.2.1 and 8.2.4 of the provisions, such as greater than the above provisions, shall take effective measures. Meet the conditions required.
23 has no driver operation elevator safety devices should be set anti-extrusion, the action should be reliable. Driver operated the elevator, the door should not be continued closure, should jog closed.
24 through Bridge car elevator, car door may not open when no layer door landing response.
25 automatic landing door should be set to automatically turn off the device, action should be flexible and reliable as it hammer institutions, the hammer should be at the bottom of the slide closures.
26 car control box should be set to cut off the control power electric lock, electric lock application-specific key control button to switch applications Chinese text annotation to indicate the name of the function.
There must be easy to identify and reach 27 car alarm device. The elevator travels more than 30 meters, the intercom device should be located between the car and the engine room.
28 safety gear on both sides of the wedge gap should be uniform, the action should be flexible and reliable.
29 compensation chain should be set to the secondary protection. Runtime compensation chain should not collide with other objects.

Hoistway

30 Rated speed> = 2.5ms, should set the compensation rope, and a safety switch and anti-pumping device.
31 floor selector contacts clean and reliable, the strip should be a safety switch.
32 bottomless pit should be set no lower than 1.7m fence on the heavy side, through wells and should be set no lower than 2.5m fence isolation.
33 car beam touch panels to buffer Distance: spring 200 - 350mm
Hydraulic 150 - 400mm
34-heavy beam touch the board to slow Distance: spring 200 - 350mm
Hydraulic 150 - 400mm
35 hydraulic buffer should be set to the reset switch, adequate oil reset flexible. Plunger vertical deviation is not greater than 0.5mm. And take dust, rust-proof measures.
The 36 governor tensioning device should be set the safety switch, the action should be flexible and reliable.
37 pit should not have water or debris, depth left at 1.6m, the ladder should be set.
38 bottomless pit should be set to automatically reset the red safety switch and power outlet.
39 balance coefficient test, balance coefficient should be 40 - 50%
40 governor Test: When the operation speed of the speed governor sheave speed to meet the design value, the overspeed governor clamping should be able to accurately action, and the governor rope.
41 security clamp experiments: when the governor tripping wedge or clamp, reliable car system stopped on the rail, and the bottom thereof tilt does not exceed 5%.
42 overload alarm safety device testing, action should be sensitive and reliable
43 Overload running test.
44 Fire function tests, the device should be sensitive and reliable.
45 from the elevator, the brake add, subtract speed test.
