optimizes scientific design and manufacture technics. And then it has high capability.

1.2 Elevator structure

1.2.1 Hoistway

1.2.1.1 Traction machine system

Traction machine system is a lifting mechanism which is installed on the special machine

supporting beams. It is composed of the following components.

a. Traction

Adopt permanent magnet synchronous gearless traction machine. Its feature is working

smoothly and high efficiency and long life and etc.

b. Brake

A normal closed magnetic brake is opening when traction electromotor electrified and

workedwhen elevator stopped, the brake is working and keep the position of car. Brake

working is opening when the electromotor electrified, and otherwise its close.

c. Traction sheave

Traction sheave has a hemicycle rope groove with cut to produce enough friction between

ropes and rope groove.

d. Anti-vibration device

Anti-vibration device which is made of rubber is fixed between concrete base and girders,


to improve the comfort of elevator operation by decreasing traction machine vibration.

1.2.1.2 Overspeed governor

Overspeed governor is connected with car by safety ropesso the moving of car cause

governor sheaves motions. And the governor will act, when the cars velocity exceeds the

regulated speed, its whole process action is shown as following:

Overspeed governor makes safety gear work by ropes immediately. At the same time,

overspeed up and down limit switch cut off the control circuit and brake circuit.

1.2.1.3 Control panel

Control panel is the control center of elevator. It is master of the running elevator all the

time and make many motion of lift under collaborations of operation panel and calling board,

such as start, up, down, stop, to have good automatic and safe capacity what we wanted.

When someone presses the calling button of a landing, control system will confirm the

move of elevator by current state. The panel also has a great variety of stator displays

which can help to maintain for workers expediently.

1.2.1.4 Guide rail

The rails are used for car and counterweight. Rail clips should be fixed on the surface of rail

brackets. When elevator is running, car and counterweight are moved along the rails, and

guarantee the position demand between car and counterweight and among wells. When

safety gear has been act, the rails should support the car (with load) or counterweight. 1.2.1.5 Counterweight

Counterweight also is connected with car by traction rope to balance the car deadweight

and 4550% rated load of the elevator, and the guide shoes should be installed on the

up-and-down ends of counterweight, in order to make counterweight slide up-and-down

along the rails.

1.2.1.6 Buffer

There are two kinds of buffers, one is spring buffer, and the other is hydraulic buffer. Buffers

should be fixed in the pit under car frame and counterweight, and it can sustain

corresponding impact from car overloading and falling with the velocity allowed by

governors. Buffer is one of the important safety components of elevator.


1.2.1.7 Well terminal switch

Well terminal switch is installed on terminal landings, which can be touched by the stick on

car. When elevator momently exceeds to the position, it should stay, well terminal switch

will force elevator to slowdown and cut off control circuit to stop car moving.

1.2.2 Landing

1.2.2.1 Landing door

There is a door to go into the car on every landing. A door lock is installed on the landing

door. Only when the car reaches the landing, the landing door should be opened and an

electric interlocking contact is installed on it. And the elevator can start to move by the

control system after door has been closed. Otherwise, if the door is opened suddenly the

car in moving will stop immediately.

1.2.2.2 Calling buttons

There is a calling button near every landing door. The calling button has one button which is

used at terminal landing or double buttons which are used at intermediate landing. A call

signal will be imputed into the control system for elevator to accept the demand after

pressing down the calling button.

1.2.2.3 Landing indicator

Landing indicator is always set on the landing door or near it, and can also be set with the

calling buttons together. There is a number to show car position and an arrowhead to show

the elevator running direction on the indicator. The lighting number shows car position at

hoistway, and the lighting arrowhead shows the elevator running direction.

1.2.3 Car structure

1.2.3.1 Car

Car is elevator container equipment, which is suspended by traction rope, and car is sliding

on guide rails by up-and-down guide shoes that are installed on the car frame. There is an

automatic opening door, which has an interlocking contact. As soon as the door is closed

right, elevator will start to work, and it will stop working when door is opened suddenly.

There is photo-electric or light curtain and etc safety device, which should be installed on

the car automatic door edge. Then in the progress of closing door when the safety device


meets passenger or barrier, it can make door stop closing at once and reverse to open

automatically.

1.2.3.2 Safety gear

Safety gear is installed under car frame plank left-and-right. When elevator drop down

overspeed, overspeed governor switch will go to work and cut off control circuit, and at the

same time, clamp safety rope, safety gear should work and lock on the guide rails, in order

to stop the elevator. If there is basement or channels under the well pit, safety gear should

also be installed on the counterweight frame.

1.2.3.3 Operation panel

Operation panel should be installed in car. So passengers or attendants can control

elevators action by buttons on the panel. In the panel there are also safety switch and

inspection switch and others.

1.2.3.4 Car indicator

Car indicator is always installed on a board of the operation panel, which has a number to

show landing position and an arrowhead to show the elevator running direction. The

lighting number shows car position at hoistway and the lighting arrowhead shows the

elevator running direction.

1.2.3.5 Automatic door machine of frequency conversion

Automatic door machine has a three phase AC frequency conversion electromotor which is

the power to drive door machine by VVVF circuit and changing the speed of electromotor.

1.2.3.6 Leveling inductor

Leveling inductor is on top of car and there is leveling magnet vane on every landing. When

leveling magnet vane insert into leveling inductor, inductor begins to work and the elevator

should be stopped. When elevator arrived at level landing and opened the door automatic

after stopping the landing, the car floor level is in accordance with landing floor level.

3.1.2 Attentions of using instruments:

The internal resistance of the avometer should be more than 200K.

The measuring range of current of AC amperemeter is 100A.

The measuring range of voltage of AC voltmeter is 500V, and the import impedance

should be more than 300 K with pointer voltmeters.

Use the high voltage megger with batteries, whose range of voltage is 00V and whose

internal resistance is above 200K. Do not use megger by hand.

The measuring range of tachometer is 0-5000r/min.

3.2 The elevator adjustment explanations 3.2.1. Adjustment of comfort:

There is impact when starting up, the mechanical system should be inspected:

a) It is easy to cause impact if the brake is not completely released or the brake is released but the brake linings are not in right position causing friction between brake

lining and brake drum.

b) Installation position of guide shoes should be confirmed. Confirm the mechanism, when there is vibration in operation.

a) Find out whether there is friction between brake lining and brake drum and whether the ropes are being extended abnormally or not.

b) Because the joint of guide rails is uneven, it should not be confused with the vibration caused by electrical system.

3.2.2. If the leveling state is not good

If the leveling error is big at particular landing, check whether the position of inductors

and leveling plate is changed in hoistway or not, adjust them if necessary. If all the leveling landing state is not good, check whether the position of inductors and

leveling plate on car side is correct or not, adjust them if necessary. 3.2.3 Check on machine system

3.2.4. Check on overspeed governor

The operation of overspeed governor should be flexible and reliable, and check to add

lithium lubrication grease into rolling bearings every year.

Keep governor tension device working in normal, check the operation reliability of the

slack-rope safety switch.

When the ropes length of overspeed governor is longer beyond permission as to cut off

control circuit, the ropes should be cut short.

Replace the ropes of governor which is worn out seriously. And the requirement of

replacement is as same as traction rope.

Check the work reliability of overspeed switches, rope clamps and grooves, and clean

sundries to keep it running.

If the overspeed system has remote operation function, please check its reliability.

3.2.5 Check on car door and automatic frequency conversion door machine

Fill lithium lubrication grease to the electromotor bearings in the car door regularly, and

clean every year.

If there is some extension of driving belts lead to lessen the tension and slide, the bolts

on the base of electromotor should be adjusted to tighten properly. Elevator will not start until the car door is closed entirely and the safety circuit acts.

Before assembling linkage device, tractions force of a door panel in any horizontal

direction is less than 3 N.

Add lithium lubrication grease to bearings of rocker arms regularly, and clean every year.

3.2.6 Check on safety gear

The joining of driving levers should be oiled with mechanical lubricant every two months. The rolling parts or sliding parts of the clips mouth should be covered with lithium

lubrication grease to make its action more flexible.

When the safety gear works, it must be able to cut off the control circuit and force the car

to stop.

The clearance between the wedge of the safety blanks and the working surface of guide

rails is about 3~4mm, and it is similar everywhere.


3.2.7 Check on guide rails and guide shoes

Check the wearing condition of the sliding guide shoe pad, if the work-surface wearing

of the pad reaches 1mm, it should be replaced. Prevent from occurring clearance

between guide shoe and guide rail to make vibration, when the car is running.

When the surface of guide rails is rough and the surface is scratched by the safety

gears operating due to a long time and little lubricants, the guide rails must be ground to

smooth before using again.

Check the guide rail equipments every year, the maintainer should stand on car top and

check slowly from up to down, and tighten all the bolts of guide rail clips, rail joints and rail supports one by one.

3.2.8 Check on buffers

Oil used for oil buffers: the freezing point should be below -10 , and viscosity target is

above 75% and oil level is also kept above minimum level.

Every 2 months check the oil level and leakage condition of buffers, add oil and tighten

all the bolts. All the bolts should be tightened. The exposed surface of plunger should be

cleaned by petrol and painted with anti-rust oil (buffer oil can also be used). Every year there is a test of piston restoration that buffers is moved from full-compressed

position to the free height position, in which the time should be less than 90s.

3.2.9 Check on landing door and interlocking device

Check the landing door and interlocking device every month make sure that the

conducting strips and contacts are fixed well, the spring leaf of contact is strong enough

to go back by itself. All the connections by riveting, welding and adhering are tightly

connected, the locking pieces, arms and rollers operation should be flexible. The bearing

should be filled with lithium lubrication grease and cleaned once a year.

Every month check the door hanging rollers which should be replaced when the value of

the trolley diameter wearing is 3mm. Check the connection bolts are tightly fastened and

cleaned the door guides weekly and make sure the wheel moves flexibly without noise or

jump. It is not allowed to open the landing door by hand outside.


Before interlocking device is assembled, tractions force of a single door panel in any

horizontal direction is less than 3 N.

Adjust the clearance between eccentricity roller of hanger rollers and the bottoms of door tracks to 0.5mm.

Add lithium lubrication grease to trolley of rocker regularly, and clean every year.

3.2.10 Check on traction ropes

1 The tensions error of traction ropes:

A When the traveling height is more than 40 meters:

1 Adjustment of tension of the ropes on the car side Stop car at a intermediate landing, and take a vibration to the ropes above the car top

with 10mm, then measure the total time when they move back and forth 5 times and the

tolerance must be consistent with regulations.

2 Tension of the ropes on the counterweight side

Stop car at some intermediate landing, and use the same adjustment and measurement as 1).

B When the traveling height is less than 40 meters:

1 Adjustment of tension of the ropes on the car side Stop car to the bottom terminal landing, and use the same adjustment and measurement as A-1).

2 Adjustment of tension of the ropes on the counterweight side Stop car at the top terminal landing, and measure the vibration of ropes on the

counterweight side. The error request is similar to A-1). Adjust the tension of wire ropes in limiting its revolving.

2 Replace it as discovering following things:

a. If the broken of steel wire is even in layers of rope, the number is more than 32 in a turn

distance.

b. If the broken of steel wire is concentrated in 1 or 2 layers of rope, the number is more

than 16 in a turn distance.

c. The steel wires abrasion and rust of traction ropes are serious.


d. The size of diameter of traction ropes by abrasion and rust is less than 90% size of the

new ropes.

3 The length of traction ropes is long enough to be shortened.

4 Clean the ropes whose surface have dunghills such as dirty oil, sand, except traction ropes.

3.2.11 Compensating device

Every month clean the guide rails and add grease in compensating device.

The length of compensating ropes is so long to be shortened.

If there is some noise in working in compensating chains, check whether the ropes are

broken or not.

3.2.12. The location of landings input (operate only in inspection state) Stop elevator at bottom terminal landing, and make car sill and landing sills in a

horizontal direction. The error isnt greater than 10mm.

Close all doors.

Drive the car by the landing height-writing from commissioning instruction.

Addenda 4: Rescue instruction

The passengers may be trapped in the elevator car when the running elevator stops suddenly between

the two floors because of the fault, power cutting etc. Usually we may move the car to door zone by

hand-winding, and then let them out. But the machine room-less system has no the hand winding device

or it is very complex because the traction motor is set in hatchway. We design the rescue system to solve

above problem. The main equipment is backup power (UPS). EEmmeerrggeennccyy rruunnnniinngg pprroocceessssMMaaiinn ppoowweerr
