1.1 Description and functions
CSGB-01/02 is a combination of disk springs and
braking elements, which are activated by a mova-
ble tripping wedge. The braking force is adjusta-
ble by the disk spring assembly. There is always a
pair of safety gears used.
The basic function of the safety gear is, if the lift
car exceeds its nominal speed upon descent, the
overspeed governor cuts in when its tripping speed
is reached and triggers the safety gear on the lift
car via the governor rope. The lift car is brought to
a standstill and clamps onto the guide rails.
The setting is carried out in the factory (according
to the load and rail conditions) and sealed. Later
adjustments will not be necessary and are in any
case prohibited for safety reasons.
The progressive safety gear is released by lifting
the car or counterweight. This returns the clamped
tripping wedge to its initial positions.
The operating range is defined as follows:
*) or lifts according EN81: +5...+40°C, General
temperature range if no tighter range is stated in
the local valid code: -5...+55°C
Care must be taken that there is no ice on
the guide rails during normal run!

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 does not take 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 is not per-
missible due to technical safety reasons:
• The use of components other than those
installed
• Carrying out modifications, of any kind on the
safety gear
• Installing two different brake heads with dif-
ferent index numbers together
• Destruction of the seal
If the seal is shacked, the complete
set of safety gears has to be replaced.
• Combining different component types
• Installing progressive safety gears intended for
other employment than that stipulated
• Carrying out faulty or improper 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
Installers and servicing personnel are fundamen-
tally responsible for their safety while working.
The monitoring and following of all valid safety
rules and legal conditions is required in order to
prevent personal injury and damage to materials
during installation, maintenance and repair work.
This refers especially to the corresponding accident
prevention rules.
Important safety advice and danger warnings are
emphasized 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
safety gears requires correspondingly well trained
fitting engineers. The responsibility of training lies
with the company appointed to carry out the
work.

Before starting installation work:
Only properly trained personnel may carry
out work, or be allowed access to the
installation site.
- Attach safety devices to guard against falling
(platform or harnesses)
- Cover any floor openings
- Secure installation tools or objects against
accidental falling
- Lift shaft openings should be cordoned off
and suitable warning signs should be erected
when working in shaft openings
- Work involving electrical equipment should
only be carried out by an electrical engineer or
qualified personnel.
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 therefore recommended
to take all the given circumstances into account
and to plan the various operational sequences in
advance, rather than carrying them out prema-
turely and in an unconsidered manner.
On the receipt of the delivery, the goods or com-
ponents should be checked for correctness and
completeness with the order sheet.
The following should be checked also:
- the factory and order number must correspond
- the details on the name plate must correspond
to those on the order
- the elevator speed
- the width and type of guide rail used
- the total load (mass to be gripped)
1.5 Advice for when working on
safety components
Safety gears are classified as safety components. It
is most important that the standards and guide-
lines described in this section are complied with as
well as those given in the rest of this operating
manual.
These instructions, and especially the sec-
tion on safety precautions, should be read
and fully understood before work begins.
Safety devices require special attention. It is com-
pulsory that they function perfectly to ensure
danger free installation operation.
Safety devices that can only be adjusted after
installation should be done so immediately after
installation.
Operation of safety devices installed ex-works
must be tested immediately.
If it is necessary to disassemble a safety device
during servicing or repair, they should be reassem-
bled and checked with the required tests, as soon
as the work has been carried out.

3.1 Fastening of the safety gear
To fasten the safety gear the in the delivery inclu-
ded srews and bushings must be used. If this is not
the case, note the following criterias:
If the screws are too short (thread engage-
ment <11mm) a secure fixing of the safety
gear isn’t guaranteed.
If the screws are too long (thread engage-
ment >13mm) the proper function of the
safety gear isn’t guaranteed.
Shim washers can be used to adjust the
thread engagement.
3.2 Movement of the safety gear
The safety gear must be able to move hori-
zontally.
Therefore the delivered bushings must be used.
Use this bushings (1) to fix the safety gear (2) on a
fixing plate (3)*) in slotted holes (4).
So the safety gear can be screwed with the fixing
screws and the safety gear can still move horizon-
tally.
Additional the safety gear must be held in position
with a spring*) (force at installation length 66N,
spring rate 2N/mm) and a variable adjustable stop
collar (6) must be in the opposite side.
*) not in the standard content of supply (with
optional housing included in delivery)
