Traction machine maintenance

Ensure that tractions wouldt restart accidentally before carry out maintenance.

If need to inspect brake should note: When there is load torque applied on the sheav or

traction machine. Release or dismantle the brake is extremely dangerous. Brake is safe

components should be adjusted by the staff with expertise.

Check the bolts and screws whether are loosen. If loosen, should tighten all the bolts and

screws.

The outer surface of the traction machine should be cleaned regularly. The oil or other

impurities between brake drum and brake shoe will lead abnormal brake force. If such situation

happens, ask maintenance personnel notify the owners of elevators stop running immediately,

then contact with the professionals to solve.

Checking regularly: Include check the traction sheave wear and tear situation, brake

flexibility, brake shoe wear and tear situation, and bearing situation.

Traction machine Bearing Life expectancy is 10 years generally. If the bearing have

abnormal noise, it may be bearing damage, abrasive situation, and so on, should replace the

bearings immediately, the replacement of bearings and oil seals should be carried by the

professionals, please contact with me on this situation.

Traction machine bearing has injected grease when leave factory, but in order to ensure the

traction machine normal use, need to add grease regularly (every 1 year). Bearings use DAPHNE

BEARING GREASE EP NO.2 (light 2) grease. If mixed-use different specification (or brand)

grease, may shorten the life span of grease.

Bearing grease supply: Grease inlet and Grease outlet is on the back of products, using

joint and rubber gasket seal to airproof it.Make the tip of the grease gun towards the grease inlet,

and press grease gun pressure levercontinually, pressed into grease, about100 cm3

everytime,

and then use joints to lock the grease inlet and gease outlet

Please do not arbitrarily discard waste grease; It should be deal with environmentally

according to industry standard.

Accessory One

Adjusting

Maintenance and Use of Brake

A traction machine is equipped with two brakes.When one of the brakes doesnt

work,another brake still can slow down the car,travelling downwards at rated speed and with

rated load,plays a role in protection.

The type of the brake is DRUM-50R. Its both a safety component of traction machine and a

major component of ascending elevator overspeed protection means.As the major component of

ascending elevator overspeed protection means,its speed monitoring device is overspeed

governor(at least electric two-way)

The lining of the brake is non-asbestos, semi-rigid.

The connection of the two brakes is parallel.

As safety component, only familiar with the brake and qualified personnel are

allowed to perform any adjusting and maintenance work.

The two brakes must be adjusted and maintained one by one,they cant be adjusted at the

same time.

Make sure nobody in the car before adjusting and maintenance.

Make sure the car and counterweight dont have any accidental travelling downwards or

upwards incipient fault exsits,before adjusting and maintenance.

When passengers are stranded in the car because of the elevator faults or power cut, if the

rescue needs to use the release handle and handwheel,then it must be actualized by two qualified

personnel who are familiar with the brake(at least two).

Work principle of brake:When the coil in the core isnt excitated,the brake lining is pressed

against the surface of the drum by the force of the brake spring,and then it produces braking

force to prevent the machine from turning;when the coil in the core is excitated, armature is

attracted to the core(overcome the force of the brake spring),makes a clearance appears between

the brake lining and drum,and then release the braking force ,the braking force is 0 now.

Structure of the brake

The brake can be released by the release handle.It can also be released by connect to the electric

release device which is according with the standard.

5 Guide Bolt 2

6 Armature

7 Release Handle

8 Release Device

The brake torque of two brakes is 490Nm.

The oil or other impurity between the lining and drum can make the braking force

abnormal,when this status occurs,the maintenance personnel must inform the owner to stop the

elevator immediately,and then contact the qualified personnel to solve the problem.

Clockwise

4 poins of air gap measure (red marks on the edge of the core)

Measure the air gap:In the state of the brake works,measure the air gap between the core

and armature of the 4 poins by means of the thickness gauge.

Measure the clearance: Tighten the middle bolt using a spanner,make the armature is

attracted to the core, measure the clearance between the lining and drum of the poins by means

of the thickness gauge.

Adjust the air gap: Tighten the middle bolt using a spanner,make the armature is attracted to

the core,,adjust the corresponding guide bolt.If the air gap is too large,turn the guide bolt2

anticlockwise using a 19mm open spanner,and then tighten the guide bolt1 clockwise using a

16mm open spanner,so the air gap will diminish. If the air gap is too small,turn the guide bolt1

anticlockwise using a 16mm open spanner,and then turn the guide bolt2 clockwise using a 19mm

open spanner,at last tighten the guide bolt1,so the air gap will largen.

In the course of adjusting,need to measure the air gapclearance and adjust bolts many

times,in order to ensure the air gap and clearance of 4 poins is according with the standard data.

When adjusting,the bolts should be turned slightly.If not,the adjusting distance will be too

large,and the guide bolt or brake will be uninstalled.

After adjusting,please ensure the guide bolt1 and guide bolt2 are tight,and then make sure to

loosen the middle bolt and put it in a loose state,to ensure the brake is braking,at last install the

cover.

Attention

The two brakes cant be adjusted at the same time,after theadjusting of one brake, make sure to loosen the middle bolt and put it in a loose

state,to ensure the brake is braking

Accessory Two:Rescue when passengers are stranded in the car because of the elevator

faults or power cut

When the elevator occurs faults or power cut,if passengers are stranded in the car,the rescue

must be performed by qualified personnel.

Before rescue,the main power must be cut off,avoid any accidental act of the elevator.

If the distance between the elevator location and one leveling location is 500mm,the

qualified personnel can open the landing door using the special key,and assist the passengers to

leave the car safety.

12


14/15


If the elevator isnt in the foregoing position the rescue needs to use handwheel to move

the car,and it needs more than 2 qualified personnels, steps are as follows:

1. Inform the passengers that rescue will be performed at once using call device, let the

passengers keep calm and tell them rescue related matters;

2. Screw the release handle to the release device as the Fig.;Insert the handwheel to the

middle hole on the basemake the small gear of the handwheel mesh with the big gear

on the sheave.

3. One personnel press the release handlesanother personnel turn the handwheel at the

same time,then the car will travel downwards or upwards slowly,when the distance

between the elevator location and leveling location is 150mm,loosen the release

handles;

4. The qualified personnel open the landing door using the special key,and assist the

passengers to leave the car safety;

5. After the passengers leave the car safety,remove the release handleand handwheel,and

lay them to the special place,and manual reset the switch on the base.If any accidental status occurs during the rescue,stop the rescue immediately,tell the

passengers to keep calm,and contact the company of the elevator.
