Isolated Roller Guides Shoes
WRG80, WRG100, WRG125, WRG200
Operating instruction

1.1 Description and functions
The types WRG80, WRG100, WRG125 and
WRG200(CWT) are used for guiding counterweight
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.
The maximum calculated roller guide force should
not exceed 70N (car side) or 100N (counterweight
side) when the car is empty.
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.
All 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).
1. Base 2. Roller
3. Arm 4. Spring
5. Movement limiter 6. Removable clamp
7. Removable slider 8. Cover
The operating range is defined as follows:
WRG80 Max. nominal speed 2,5m/s
Weight (4 pcs.) 13,2kg
Max. counterweight mass 3200kg
WRG100 Max. nominal speed 3,5m/s
Weight (4 pcs.) 25kg
Max. counterweight mass 5000kg
WRG125 Max. nominal speed 7,0m/s
Weight (4 pcs.) 25,6kg
Max. counterweight mass 5000kg
WRG200 Max. nominal speed 10,0m/s
(CWT) Weight (4 pcs.) 68,4kg
Max. counterweight mass 7000kg
Never use roller guide shoes with the roll
formed HT type guide rails. Roller guide
shoes effects noise on low quality HT rails.

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 precautions
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.

Operating instruction
2.1 Adjustment of the position of the
roller guides
The installation could be done during counter-
weight frame assembling or also afterwards if the
elevator is to be modernised.
Check from the layout drawing whether counter-
weight shift has been used. If used, check that the
counterweight frame is correctly assembled.
•Check the position of the slider
Make sure that the plastic slider firmly touch-
es the guide rail when the counterweight is in
the correct position.
•Check the position of the guide rail
The slot hole of the base should be central to
the guide rail, and should have the required
gap A (see table) between the 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

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 lubricated)!

5.1 Maintenance and inspection
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.
Maintenance and inspection 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

5.2 Carrying out repairs
Damaged parts of the guide shoe cannot
be repaired. The damaged parts must be
replaced. Only use WITTUR spare parts.
Repairs should be expertly carried out with
utmost care in order to guarantee safe
installation operation.
5.2.1 Changing of rollers
(example WRG125)
Remove the roller fixing (nut M12) and take off
the whole roller (incl axle)
To ease the replacement, you can wind up
the movement limiter screw and turn out
the roller lever.
Note: For readjustment of the spring
tension and limiter gap refer to
chapter 3.
Follow all the local safety instructions dur-
ing the maintenance work.
Please contact WITTUR if for any reason something
is unclear, or you encounter damage that cannot
be repaired with the help of these instructions.
