Progressive Safety Gear
USG-25P
Operating Instructions
1.1 Description and functions
The progressive type safety gear USG-25P is a
combined c-type spring, frame and friction ele-
ment, which is activated by a movable roller. The
braking force is adjusted by means of variable
machining dimensions, therefore the re-adjusting
is impossible. The safety gears are fixed normally
below the car or counterweight frame. There is
always a pair of safety gears used.
When the tripping speed of the overspeed gover-
nor is reached during downward drive, the safety
gear is engaged.
The overspeed governor rope is blocked and pulls
the lifting lever up into brake position. Both safe-
ty gears, connected by a gripping shaft will grip
at the same time.
The uniform braking of both safety gears is
caused by a good synchronisation during mount-
ing. This must be done very carefully.
The release of the safety gear is done by moving
the car or counterweight upward about 100mm.
With the exception of resetting the safety switch,
which must be done by trained personal (if the
safety gear is equipped with a manual resetable
switch), is the safety gear ready for operation im-
mediately.
If this safety component is handled with care and
scheduled examination is performed, it will be
very long live and fail save.
The operating range is defined as follows:
• max. elevator speed 2,0 m/s
• width of guide rail head 8 - 16 mm
• max. mass to be gripped max = 2600kg
• governor tripping force max. 1000N

Progressive Safety Gear
USG-25P
Operating Instructions
1.2 iability 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
stated 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
permissible due to technical safety reasons:
• The use of components other than those in-
stalled
• Carrying out modifications, of any kind on
the safety gear
• Installing two different brake heads with dif-
ferent index numbers together
• 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 con-
sists 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 (e.g.
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.

Progressive Safety Gear
USG-25P
Operating Instructions
Before starting installation work:
Only properly trained personnel may carry
out work, or be allowed access to the in-
stallation 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 recommended therefore,
taking into account all the given circumstances,
to plan the various operational sequences in ad-
vance, rather than carrying them out prematurely
and in an unconsidered manner.
On receipt of the delivery, the goods or compo-
nents should be checked for correctness and
completeness with the order sheet.
The following should be checked also:
- that factory and order number correspond
- that the details on the name plate correspond
to those on the order
- the width and type of guide rail used
- the total load max (P+Q)
- the elevator tripping speed
1.5 Advice for when working on
safety components
Safety gears are classified as safety components.
It is most important that the standards and
guidelines described in this section be complied
with as well as those given in the rest of this op-
erating 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 in-
stallation should be done so immediately after in-
stallation.
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 re-
assembled and comply with the required tests, as
soon as the work has been carried out.
1.6 Content of supply
Check the delivery for correctness, com-
pleteness and condition on the basis of
the order.
Depending on the order the content of supply
can cover:
- One left handed and one right handed safety
gear
- Operating instructions manual
Optional:
- Housing
- Safety switch
(manual or self resetting type)
- Synchronisation shaft
- Rope hitch

3.1 Mounting to the car frame
In accordance to the delivery content the manner
of how to mount it to the car frame is deviating:
• Mounting with flat bars (see chapter 3.1.1)
(e.g. integrated directly to the upright)
• Safety gear with housing (see ig.1)
• If mounting method is different, additional
documentation in included in delivery
In general:
Brake shoe and guide rail must be verti-
cally and horizontally lined up in parallel!
The following malfunction of the safety
gear may appear because of inaccurate
mounting:
• unintended gripping of the Roller
• no 100% braking extent
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.
