Introduction
Elementary safety warnings
User target groups
▪ This booklet is aimed at all persons who will be work-
ing with the Doka product or system that it describes.
It contains information on the standard design for
setting up this system, and on correct, compliant uti-
lisation of the system.
▪ All persons working with the product described
herein must be familiar with the contents of this
booklet and with all the safety instructions it contains.
▪ Persons who are incapable of reading and under-
standing this booklet, or who can do so only with dif-
ficulty, must be instructed and trained by the cus-
tomer.
▪ The customer is to ensure that the information mate-
rials provided by Doka (e.g. User Information book-
lets, Instructions for Assembly and Use, Operating
Instruction manuals, plans etc.) are up to date and
available to all users, and that they have been made
aware of them and have easy access to them at the
usage location.
▪ In the relevant technical documentation and form-
work utilisation plans, Doka shows the workplace
safety precautions that are necessary in order to use
the Doka products safely in the usage situations
shown.
In all cases, users are obliged to ensure compliance
with national laws, standards and regulations
throughout the entire project and to take appropriate
additional or alternative workplace safety precau-
tions where necessary.
Hazard assessment
▪ The customer is responsible for drawing up, docu-
menting, implementing and continually updating a
hazard assessment at every job-site.
This booklet serves as the basis for the site-specific
hazard assessment, and for the instructions given to
users on how to prepare and utilise the system. It
does not substitute for these, however.
Remarks on this booklet
▪ This booklet can also be used as a generic method
statement or incorporated with a site-specific
method statement.
▪ Many of the illustrations in this booklet show the
situation during formwork assembly and are
therefore not always complete from the safety
point of view.
Any safety accessories not shown in these illustra-
tions must still be used by the customer, in accord-
ance with the applicable rules and regulations.
▪ Further safety instructions, especially warnings,
will be found in the individual sections of this
booklet!
Planning
▪ Provide safe workplaces for those using the form-
work (e.g. for when it is being erected/dismantled,
modified or repositioned etc). It must be possible to
get to and from these workplaces via safe access
routes!
▪ If you are considering any deviation from the
details and instructions given in this booklet, or
any application which goes beyond those
described in the booklet, then revised static cal-
culations must be produced for checking, as well
as supplementary assembly instructions.
Regulations; industrial safety
▪ All laws, Standards, industrial safety regulations and
other safety rules applying to the utilisation of our
products in the country and/or region in which you
are operating must be observed at all times.
▪ If a person or object falls against, or into, the side-
guard component and/or any of its accessories, the
component affected may only continue in use after it
has been inspected and passed by an expert.

Rules applying during all phases of
the assignment
▪ The customer must ensure that this product is
erected and dismantled, reset and generally used for
its intended purpose in accordance with the applica-
ble laws, standards and rules, under the direction
and supervision of suitably skilled persons.
These persons' mental and physical capacity must
not in any way be impaired by alcohol, medicines or
drugs.
▪ Doka products are technical working appliances
which are intended for industrial / commercial use
only, always in accordance with the respective Doka
User Information booklets or other technical docu-
mentation authored by Doka.
▪ The stability and load-bearing capacity of all compo-
nents and units must be ensured during all phases of
the construction work!
▪ Do not step on or apply strain to cantilevers, clo-
sures, etc. until suitable measures to ensure their
stability have been correctly implemented (e.g. by
tie-backs).
▪ Strict attention to and compliance with the functional
instructions, safety instructions and load specifica-
tions are required. Non-compliance can cause acci-
dents and severe injury (risk of fatality) and consid-
erable damage to property.
▪ Sources of fire in the vicinity of the formwork are pro-
hibited. Heating appliances are only allowed if prop-
erly and expertly used, and set up a safe distance
away from the formwork.
▪ The customer must consider all types of weather
conditions on equipment and in connection with the
use or storage of the equipment (e.g. slippery sur-
faces, risk of slippage, effects of wind, etc.) and must
take steps in good time to safeguard the equipment
and the surrounding areas and to protect the work-
ers.
▪ All connections must be checked at regular intervals
to ensure that they are secure and in full working
order.
In particular threaded connections and wedged con-
nections have to be checked and retightened as nec-
essary in accordance with activity on the jobsite and
especially after out-of-the-ordinary occurrences (e.g.
after a storm).
▪ It is strictly forbidden to weld Doka products – in par-
ticular anchoring/tying components, suspension
components, connector components and castings
etc. – or otherwise subject them to heating.
Welding causes serious change in the microstruc-
ture of the materials from which these components
are made. This leads to a dramatic drop in the failure
load, representing a very great risk to safety.
It is permissible to cut tie rods to length with metal
cutting discs (introduction of heat at the end of the
rod only), but it is important to ensure that flying
sparks do not heat and thus damage other tie rods.
The only articles which are allowed to be welded are
those for which the Doka literature expressly points
out that welding is permitted.
Assembly
▪ The equipment/system must be inspected by the
customer before use, to ensure that it is in suitable
condition. Steps must be taken to rule out the use of
any components that are damaged, deformed, or
weakened due to wear, corrosion or rot.
▪ Combining our formwork systems with those of other
manufacturers could be dangerous, risking damage
to both health and property. If you intend to combine
different systems, please contact Doka for advice
first.
▪ The equipment/system must be assembled and
erected in accordance with the applicable laws,
Standards and rules by suitably skilled personnel of
the customer's, having regard to any and all required
safety inspections.
▪ It is not permitted to modify Doka products; any such
modifications constitute a safety risk.
Closing the formwork
▪ Doka products and systems must be set up so that
all loads acting upon them are safely transferred!
Pouring
▪ Do not exceed the permitted fresh-concrete pres-
sures. Over-high pouring rates overload the form-
work, cause greater deflection and risk breakage.
Stripping out the formwork
▪ Do not strip out the formwork until the concrete has
reached sufficient strength and the person in charge
has given the order for the formwork to be stripped
out!
▪ When stripping out the formwork, never use the
crane to break concrete cohesion. Use suitable tools
such as timber wedges, special pry-bars or system
features such as Framax stripping corners.
▪ When stripping out the formwork, do not endanger
the stability of any part of the structure, or of any
scaffolding, platforms or formwork that is still in
place!

Introduction User Information Load-bearing tower Staxo 100
Transporting, stacking and storing
▪ Observe all country-specific regulations applying to
the handling of formwork and scaffolding. For system
formwork the Doka slinging means stated in this
booklet must be used - this is a mandatory require-
ment.
If the type of sling is not specified in this booklet, the
customer must use slinging means that are suitable
for the application envisaged and that comply with
the regulations.
▪ Remove any loose parts or fix them in place so that
they cannot be dislodged or fall free!
▪ All components must be stored safely, following all
the special Doka instructions given in the relevant
sections of this booklet!
Maintenance
▪ Only original Doka components may be used as
spare parts. Repairs may only be carried out by the
manufacturer or authorised facilities.
Miscellaneous
The weights as stated are averages for new material;
actual weights can differ, depending on material toler-
ances. Dirt accretions, moisture saturation, etc. can
also affect weight.
We reserve the right to make alterations in the interests
of technical progress.

Eurocodes at Doka
In Europe, a uniform series of Standards known as
Eurocodes (EC) was developed for the construction
field by the end of 2007. These are intended to provide
a uniform basis, valid throughout Europe, for product
specifications, tenders and mathematical verification.
The EC are the world's most highly developed Stand-
ards in the construction field.
In the Doka Group, the EC are to be used as standard
from the end of 2008. They will thus supersede the DIN
norms as the "Doka standard" for product design.
The widely used "Permissible stress design" (compar-
ing the actual stresses with the permissible stresses)
has been superseded by a new safety concept in the
EC.
The EC contrast the actions (loads) with the resistance
(capacity). The previous safety factor in the permissible
stresses is now divided into several partial factors. The
safety level remains the same!
Comparison of the safety concepts (example)
EdDesign value of effect of actions
(E ... effect; d ... design)
Internal forces from action Fd
(VEd, NEd, MEd)
RdDesign value of the resistance
(R ... resistance; d ... design)

The "permissible values" communicated in
Doka documents (e.g.: Qpermissible = 70 kN)
do not correspond to the design values
(e.g.: VRd = 105 kN)!
➤Avoid any confusion between the two!
➤Our documents will continue to state the per-
missible values.
Allowance has been made for the following par-
tial factors:
γF = 1.5
γM, timber = 1.3
γM, steel = 1.1
kmod = 0.9
In this way, all the design values needed in an
EC design calculation can be ascertained from
the permissible values.

System description
Load-bearing tower Staxo 100 – the
extra-high-capacity, fast load-bearing
tower made of steel, with integral
safety features
Staxo 100 comes with all the field-proven advantages
of Staxo – meaning that it is robust, fast and versatile.
On top of all this, Staxo 100 has been given an exten-
sive package of built-in safety features, and its load
capacity greatly increased.
Sturdy galvanised steel frames, in three different
heights, are the basis of this high-speed, high-perfor-
mance load-bearing tower system.
High load-bearing capacity, quick and easy assembly
using integrated connectors, and great versatility -
these are the outstanding characteristics of Staxo.
Wherever high loads occur, in either the building-con-
struction or civil-engineering fields, this load-bearing
tower is the ideal solution.
The high-performance load-bearing tower
▪ high capacity of up to 100 kN per leg
▪ with lightweight components (frames up to h=1.20 m
can be manhandled)
▪ ergonomical: easy-to-handle parts
... speeds up work
▪ the small number of system components makes for
easier handling and means that no time is wasted
searching for parts
▪ the connector components are captively integrated
into the frames and so cannot be lost
▪ no tools are needed for assembling the towers
... provides optimum safety
▪ high stability, due to its 1.52 m wide frames
▪ slip-proof ladders integrated in the frames
▪ suspension points for chest harness
... is flexible
▪ the inter-frame spacing can be varied (from 0.60 m
to 3.00 m), for optimum utilisation of the frames'
load-bearing capacity. (From 1.00m, in 50 cm incre-
ments).
▪ different frame heights - 0.90 m, 1.20 m and 1.80 m
- for rough height adjustment in 30 cm increments:
0.90, 1.20 and 1.80 m
▪ fine adjustment by means of screw-jack U-heads
and feet
▪ can be used in conjunction with floor props and
Dokaflex
... is economical
▪ The tower units are quick and easy to assemble:
- either on their sides or in the upright
- for tall towers, tower units can be pre-assembled
on their sides, and then simply stacked by crane
- scaffold planking units make it easy to erect and
dismantle the tower and superstructure
▪ with special wheel units, complete tableforms can
quickly be wheeled to their next location
▪ the Forklift shifting device TG makes the job of erect-
ing, dismantling and transporting Doka load-bearing
towers very much easier.

Areas of use
The Load-bearing tower Staxo is ideal:
▪ as falsework for use in bridge-building, where high
loads occur and where great stability is called for in
that horizontal forces such as wind loads have to be
safely transferred
▪ in the building construction field, e.g. for administra-
tion buildings and multistorey car-park decks, where
large-area tableform units reduce forming times
▪ in the industrial and power-station construction field,
as a load-bearing tower for all manner of applications
Doka stair tower 250
The Doka stair tower 250 consists of 1.20 m frames and
a small number of light-weight aluminium stairway ele-
ments.
Quick to erect, the stair tower provides 'high-level'
safety and lets the site crew get quickly to their work-
places.

WARNING
Never climb up or down the outside of the
tower! You risk falling and/or causing the tower
to tip over!
➤Only ever climb up the inside of the tower.
When doing this, make sure that the scaffold
planking units are in the correct positions (as
intermediate landings)!

Practical examples
Tableforms and tower frames are both assembled from
the same system components.
Tableform units
▪ For repetitive use, the load-bearing tower can be
assembled into complete table-forms.
Combined with Dokaflex
For downstand beams, the load-bearing towers and
beam-forming supports can be combined very effec-
tively with Dokaflex.
Edge floor-beam
Tower frames
With a load-bearing capacity of up to 97 kN per leg,
Staxo 100 is an extremely strong load-bearing tower
system.
It safely withstands horizontal forces such as wind
loads.
The wide frames make for high stability right from the
word 'go'.
Close inter-frame spacing is possible, for transferring
high loads.

Shoring load-bearing structures
On bridges, culverts and industrial structures, the load-
bearing tower and Doka large-area formwork Top 50
together make an ideal combination.
In this way, even complex structures can be formed
using mostly standard parts - at lower cost.

Adapts to different ground plans, heights, floor shapes and loads
The different sizes of diagonal brace for each height of
frame enable the frames to be spaced close together or
further apart, depending on the load.
In this way, only as much material is used as is really
needed.
e.g. light loads – frames spaced further apart e.g. heavy loads – frames spaced close together

Height ranges and materials schedule
Frame-sizes up to 1.80 m
1.80m, 1.20m and 0.90m frames are possible here.
Table A
Choose the right diagonal crosses for the distance between the frames.
The schedule of materials does not include scaffold planking units.
The scaffold planking units have to be planned separately for each set-up configuration. Provided they are located in the same level, they replace
the Diagonal crosses 9.xxx needed for horizontal bracing. This reduction in the number of diagonal crosses needed must be allowed for in the
schedule of materials.
NOTICE
▪ The minimum values hmin. given in Table A
are only applicable if the biggest possible
frame is always used in the base section.
▪ The lowering distance of 6 cm is already
allowed for in Table A!
▪ LK and LF are in accordance with the struc-
tural design. In some cases, the structural
design will permit greater extension lengths
- see Tables B and C in the section headed
'Height adjustment'.
