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 document can be used as general Instructions
for Assembly and Use (Method Statement) or be
incorporated into site-specific Instructions for
Assembly and Use (Method Statement).
▪ The graphics, animations and videos in this doc-
ument or app sometimes depict partially assem-
bled assemblies and may require additional
safety equipment and/or measures to comply
with safety regulations.
The customer must ensure all applicable regulations
are complied with, even if they are not shown or
implied in the graphics, animations and videos pro-
vided.
▪ Individual sections contain further safety
instructions and/or special warnings as applica-
ble.
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.

User Information Load-bearing tower Staxo 100 eco Introduction

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. Heaters are permissible only when used cor-
rectly and situated a correspondingly safe distance
from the formwork.
▪ Customer must give due consideration to any and all
effects of the weather on the equipment and regards
both its use and storage (e.g. slippery surfaces, risk
of slipping, effects of the wind, etc.) and implement
appropriate precautionary measures to secure the
equipment and surrounding areas and to protect
workers.
▪ 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 individual 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 an accept-
able condition. Steps must be taken to exclude com-
ponents that are damaged, deformed, or weakened
due to wear, corrosion or rot (e.g. fungal decay).
▪ Using our safety and formwork systems together
with those of other manufacturers can create risks
that may lead to injury and damage to property. This
requires separate verification.
▪ The equipment/system must be assembled and
erected in accordance with the applicable laws,
standards and rules by trained customer personnel
whilst maintaining any applicable safety inspections
that may be required.
▪ It is not permitted to modify Doka products; 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 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!

6999808702 - 11/2019
Introduction User Information Load-bearing tower Staxo 100 eco
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 document,
the customer must use slinging means that are suit-
able for the application envisaged and that comply
with the regulations.
▪ When lifting, always make sure that the unit to be
lifted and its individual parts can absorb the forces
that occur.
▪ Remove loose parts or secure them so that they can-
not slip out of position and drop.
▪ All components must be stored safely, following all
the special Doka instructions given in the relevant
sections of this document!
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
The permissible values stated in Doka documents
(e.g. Fperm = 70 kN) are not design values (e.g. FRd =
105 kN)!
▪ It is essential to avoid confusing permissible values
with design values!
▪ Doka documents will continue to state the permissi-
ble values.
Allowance has been made for the following partial fac-
tors:
▪ γF = 1.5
▪ γM, timber = 1.3
▪ γM, steel = 1.1
▪ kmod = 0.9
Consequently, all the design values for an EC design
calculation can be determined from the permissible val-
ues.

and extra-economical shoring system
Staxo 100 eco comes with all the field-proven advan-
tages of Staxo 100 – meaning that it is robust, fast and
versatile.
Sturdy galvanised or painted steel frames, in three dif-
ferent heights, are the basis of this high-speed, high-
performance load-bearing tower system.
High load-bearing capacity, quick and easy assembly
and great versatility – these are the outstanding char-
acteristics of Staxo 100 eco.
Wherever high loads occur, in either the building-con-
struction or civil-engineering fields, this load-bearing
tower is the ideal solution.

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 1.20m frames and
a small number of lightweight aluminium stairway ele-
ments.

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.
Height ranges and materials schedule
Frame-sizes up to 1.80 m
1.80m, 1.20m and 0.90m frames are possible here.

Frame-sizes up to 1.20 m
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 brac-
ing. 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 storey.
▪ 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'.
▪ Greater extension lengths are possible (up
to max. 45 cm) if the head units and/or base
units are given suitable scaffold-tube brac-
ing.
▪ In principle, it is possible to use Heavy-duty
screw jacks 70 and Heavy-duty screw jacks
70 top. However, when these are combined
with the small frames, you must observe the
limitations given in Tables B and C of the
section headed 'Height adjustment'.

Height adjustment
▪ The 3 different heights of frame 0.90 m, 1.20 m and
1.80 m enable coarse adjustment to within 30 cm.
▪ Fine adjustment, down to the last millimetre, is done
using the various head and base units.
