1.1 Description and functions
The progressive type safety gear S B03 is a combination
of c-type springs, frame and friction elements, which are
activated by a movable activating wedge. The braking
force is variable by means of an adjustable counter wedge.
The basic function of the safety gear is, if the lift car
exceeds its rated speed upon descent, the overspeed gov-
ernor cuts in when its tripping speed is reached and trig-
gers 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.
This returns the clamped brake wedge to its initial posi-
tions.
The operating range is defined as follows:
• max. elevator speed [v]
2,50 m/s
• width of guide rail head [k]
15,88 - 31,75 mm
• min. mass to be gripped [Fmin]
8.100 kg
• max. mass to be gripped [Fmax]
17.692 kg
• max. tripping force of the overspeed governor
2350 N
• temperature during operation
-20 ... +50°C
• temperature during storage
-40 ... +70°C
• max. air humidity
95% / +25°C
93% / +40°C

1.2 Liability and guarantee
This operating manual is written for people who
are familiar with lift servicing and installation.
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 lead seal
If the lead 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:
eneral 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 Gripping wedge synchronization
and adjustment
After installation of the car frame and the guides,
the correct centering and adjustment of the safe-
ty gear with regard to the rails has to be done.
When mounting the safety gear, observe
the position of the overspeed governor
rope. The position of the lifting lever of the
rope at the safety gear cannot be changed
if the safety gear is built in.
(1) Slacken nuts (1) and (2). The springs (3) have
to be completely loosened and the fixing links
(4) of both safety gears have to rest against
the spring block (5).
(2) Screw in the two nuts (2) against the spring
(3) and then compress the springs with a fur-
ther 1.5 turns of each nut.
The compression is correct if the distance
between the ends of the springs is approx-
imately 155 mm, respectively 165 mm (see
figure above).
