Isolated Roller Guides Shoes
WRG200, WRG300
Operating instruction

1.1 Des ription and fun tions
The types WRG200 and WRG300 are used for guid-
ing car frames.
Generally:
- The isolated roller guide works as a spring ele-
ment, so that the vibrations are limited to the
minimum
- It guides the car between the guide rails with-
in the allowance determined by the safety
gear device and the door coupler (in reality
approx. ±2mm)
When such roller guides are used, the elevator
must be both statically and dynamically balanced.
Isolated roller guide shoes are distinguished by its
spring system which offers enormous advantages
over non-springloaded guides. The rollers always
contact the rail closely regardless of the type and
direction of load.
The rollers are assured and unusually long service
life by the spring system and their being in con-
stant contact with the rail.
The roller guides are sealed and preadjusted at the
factory, therefore it is not allowed to adjust the
springs and movement limiters (removable clamps
and sliders are used during installation and bal-
ancing).
Never use roller guide shoes with the roll
formed HT type guide rails. Roller guide
shoes effects noise on low quality HT rails.
The operating range is defined as follows:

Max. nominal speed 5,0m/s
Max. roller force during run (empty car) 70N
Max. roller force during loading 3000N

1.2 Liability and guarantee
This instruction handbook is written for people
who are familiar with lift servicing and installa-
tion. Sufficient knowledge of lifts is essential.
WITTUR accept no responsibility for damage
caused by improper handling, or for damage
caused as a result of actions other than those stat-
ed in these operating instructions.
The WITTUR guarantee may be voided if parts
other than those described in these instructions
are installed.
Unless stated otherwise, the following are not per-
missible due to technical safety reasons:
• use other means of fixation than prescribed
• install the sliding guide shoes in another way
than described in this operating manual
• Carrying out modifications, of any kind
• Carrying out faulty or improper maintenance,
maintenance or inspection checks
• using unsuitable accessories, spare parts or
operating material which has neither been re-
leased by the WITTUR Company nor consists of
original WITTUR spare parts
1.3 Safety pre autions
WITTUR machine installation or repair engineers
are chiefly responsible for the safe operation of
machinery.
It is essential to comply with and keep abreast of
all safety rules and legal obligations in order to
avoid personal / product damage during installa-
tion, maintenance and repair work.
Important safety advice and danger warnings are
emphasised with the following symbols:
General danger warning
High danger risk warning (i.e. crushing
edge, cutting edge etc.).
Risk of damage to machinery parts (i.e. due
to incorrect installation, or such like).
Important information sign
These operating instructions belong with the
whole installation and must be kept in a safe place
at all times (i.e. machine room).
The proper assembly and installation of WITTUR
brake systems requires correspondingly well
trained fitting engineers. The responsibility of
training lies with the company appointed to carry
out the work.
1.4 Preparation
Before beginning installation work it is in your
own interest to ascertain the constructional and
spatial conditions. Where (workshop or on site)
and when which installation operations can or
must be carried out. It is recommended therefore,
taking into account all the given circumstances, to
plan the various operational sequences in advance,
rather than carrying them out prematurely and in
an unconsidered manner.
Note the safety regulations for working on eleva-
tors.

2.1 Adjustment of the position of the
roller guides
The installation could be done during car frame
assembling, or also afterwards if the elevator is to
be modernised.
The first steps are balancing and safety gear
adjustment - see chapter 3 “balancing of elevator
cars provided with factory adjusted roller guides”.
• Che k the position of the slider
Make sure that the plastic slider firmly touch-
es the guide rail when the car is in the correct
position.
• Che k the position of the guide rail
The slot hole of the base should be central to
the guide rail, and should have the required
5mm gap between the guide rail and the bot-
tom of the slot.
If these requirements are not achieved the
roller guides are most probably not straight
and must be aligned as
described in chapter 2.2

3.1 General
If the elevator car is not balanced, the sliding and
roller guide shoes are subject to excessive load.
This leads to rapid wear of the guide shoes and in
case of roller guide shoes to quaky running, which
can be felt in the car. Therefore all cars must be
balanced independent of speed and travelling
height.
Accurate balancing can be carried out first after
the car is fully installed and suspended by the
ropes.
The removable clamps and sliders are used to ease
the balancing and installation.
3.2 Balan ing
Before the balancing is done the roller guides must
be aligned using the door lines as reference line:
• Drive the car to a suitable working height near
the lowest floor level
• Adjust the position of the roller guides so that
the gap between the car door and the landing
door is equal at top, bottom, left and right
(refer to chapter 2.1 and 2.2).
check also that the safety gear can still be
adjusted side ways.
Do not try to untwist the car frame with
the roller guides. If untwisting is required,
then loosen the top fixing between car and
the frame, force the frame to right position
and tighten the fixings.

3 Balan ing of elevator ars provided with fa tory adjusted
roller guides

• Drive the car to the floor which is nearest to
the mid-point of the shaft, take a suitable
amount of balancing weights with you.
• Remove the plastic sliders of the top roller
guides
• Carefully balance the car by placing balance
weights on car floor, directly above the fixing
profile. The car is balanced, when there is
equal gap between each top roller and the
guide rail, or the rollers and the rail touch
each other so, that the car can be moved with
“one finger”
The adjusting of balance must be done so
that own weight is not affecting the bal-
ance. You can check the balance by stand-
ing at the hitch point, from another car (in
case of multiple cars in one shaft) etc.
Remember to use a safety rope when
required.

3.3 The final he king of the balan e
Before the balancing is complete all clamps
and sliders of the bottom roller guides are
removed, then the final checking is done.
• Remove the clamps of the top roller guides
• Drive the car down
• Remove the clamps and sliders of the bottom
roller guides
• Drive the car back to the mid-point of the
shaft
• Check the balance from the gap “A” of the top
roller guides movement limiters (see chapter
4). If it is necessary, adjust the position of bal-
ance weights.
• Before new checking, sway the car powerful
back and forth in lateral and depth direction
to overcome the friction between the rollers
and the guide rail.
• Drive the car down and shift the weights to
exactly the same place at the fixing profile.
• Fasten the weights to the fixing profile
The adjusting of balance must be done so
that own weight is not affecting the bal-
ance. You can check the balance by stand-
ing at the hitch point, from another car (in
case of multiple cars in one shaft) etc.
Remember to use a safety rope when
required.

Operating instruction
Provided that the system has been properly
installed in accordance with all guidelines, it can
be assumed the proper functioning of the roller
guide shoes is guaranteed.
The individual components are strictly checked for
quality and function and are tested before leaving
our factory.
The guide shoes must not stick and should
Check that the guide shoes are tightly
screwed to the car frame or counterweight
before starting the function test.
Test run after installation:
Prior to first test run
Clean the guide rails!
Clear all people and objects from the lift
shaft before commencing the test run
Risk of crushing injuries!
The entire lift travel path should be slowly trav-
elled (in inspection mode) before the functions
tests. Attention should be paid to the clearance of
all fastened parts, especially with regards to the
guide brackets/safety gear devices. Find and
remove any protruding bolts or other dangerous
restrictions well in advance.
The guide shoes must not stick and should
easily move.
All roller guide shoes have to be used dry
(not lubri ated)!
5.1 Test run
• For balancing refer to chapter 3
• Drive up and down a few times with service
speed and check the clearances of the landing
door lock and other shaft equipment
• Sway the car powerful back and forth in lat-
eral and depth direction. Check that the car
adopts its correct position again and that the
rollers (which have equal pressure) can be
turned around by hand. If that is not the case,
the car is not sufficient balanced.
• Drive several times up and down with nominal
speed, stand in various places in the car and
observe the elevator’s performance
Always drive in up-direction for the first
time with nominal speed (danger of grip-
ping).
• A jerky ride is a sign of wrong roller guide
adjustment, unbalance of the car, or wrongly
aligned guide rails.
• Carry out test drive with half load located in
both front and rear parts of the car. Drive first
with service speed and check the clearance
between the door coupler and the lock rollers.

6.1 Maintenan e and inspe tion
Inspection checks must be carried out at regular
intervals (minimum twice a year with each service)
to guarantee safe operation.
Alterations, damage or other irregularities should
be reported, and repaired if possible. Frequent
servicing and control checks not only make opera-
tion of the installation safer, but also ensure long
and reliable service life.
It is recommended that control checks and servic-
ing be carried out before legally prescribed func-
tional tests (e.g. before TÜV tests).
The lift installation must be immediately
taken out of use should any damage or
irregularities arise which could possibly
impair operational safety.
Please contact us at WITTUR if you have
any problems or queries.
Maintenance work should be expertly car-
ried out with utmost care in order to guar-
antee safe installation operation.
Maintenan e and inspe tion plan
General:
• Visual control of general condition for irregu-
larity (e.g. contamination, corrosion, deforma-
tion, splitting)
• Clean the roller guide shoes with a clean towel
if dirty
• Check of screw connections of guide shoes
• Check spring condition and tension
The adjustment is right, if the roller can be
turned easily by hand.
• Check the locking of the lock nuts
• Check the roller; change it if it has worn out
remarkably
• Check that the roller surface is smooth
• Measure the movement limiter dimensions
