Elementary safety warnings

Symbols usedThe following symbols are used in this booklet:

MiscellaneousWe reserve the right to make alterations in the inter-ests of technical progress.Unless otherwise stated, all dimensions are given in cm.

� Doka products and systems must be set up in such a way that all loads acting upon them are safely transferred!

� The stability of all components and units must be ensured during all phases of the construc-tion work!

� Provide safe workplaces for those using the formwork (e.g. for when it is being erected/dis-mantled, modified or repositioned etc). It must be possible to get to and from these workplaces via safe access routes!

� Do not exceed the permitted fresh-concrete pressures. Excessively high pouring rates lead to formwork overload, cause greater deflection and risk causing breakage.

� Do not strike the formwork until the concrete has reached sufficient strength and the person in charge has given the order for the formwork to be struck!

� When stripping the gang-form, never use the crane to break concrete cohesion. Use suitable tools such as timber wedges or a special pry-bar.

� When striking 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!

� Observe all regulations applying to the hand-ling of formwork and scaffolding. In addition, the Doka slinging means must be used - this is a mandatory requirement.

General remarks User information Doka automatic climbing formwork

System description

Automatic climbing formwork SKE -

The crane-independent climbing

formwork for structures of any

shape and height

The SKE system is used for raising:� large-area formwork elements� together with the climbing scaffold� in one single step� and without any crane assistanceby one casting section at a time.

Safety is always absolutely paramount here

The Doka automatic climbers are tested by inde-pendent institutes, who also certify their high qual-ity and safety.

Superlative product quality

� Sturdy hot-dip galvanised components� Certified to ISO 9002

Maximum safety in all phases of the work

� The climbing scaffold remains anchored to the concrete at all times.

� The lifting mechanism is safely coupled to the climbing profile in every situation.

� Wide working platforms, enclosed by handrails on all sides, enhance both safety and speed.

Hydromechanical drive provides optimum

control and operational safety

� Simultaneous controlling of:- up to 30 automatic climbers- by remote-control- from anywhere on the platform

� Isolation valves on the hydraulic cylinders� Open ring main� Closed ring main� Hydraulic units equipped with all necessary con-

trol features

High load-bearing capacity

Doka offers 2 models of automatic climber:� SKE 50, with 5 tonnes' lifting capacity per auto-

matic climber, and� SKE 100, with 10 tonnes' lifting capacity per auto-

matic climberThis enables the formwork to be optimally dimen-sioned to suit each project, which in turn greatly enhances the economic efficiency.

Makes work independent of climatic influ-

ences

� Permits safe working at wind speeds of up to 70 km/h

� Climbing can take place regardless of climatic influences. Working platforms can be weather-proofed.

The advantages of "section-at-a-time" climb-

ing

� Freely selectable workflow with no need for "round-the-clock" working

� The cycles are optimised for the construction task in question, right from the planning stage.

� Project-specific live load ratings� Rapid work rhythm

Set up, strip, climb- with no need for a crane- in any weather- independently of other forming operations

such as subsequently formed floor-slabs and walls

- short repositioning time of 1-2 hours, depend-ing on the height of the casting section and the number of automatic climbers

Optimum adaptability to every layout

The Doka automatic climber SKE is a single-unit lift-ing appliance. This results in:� optimum configurations, irrespective of the

shape of the layout� flexibility with regard to element widths� the most economical solution can be achieved

for all layouts of buildings, piers or shafts.

Doka planning service

Doka will be pleased to plan an economical form-work solution for you, and partial pre-assembly of the formwork by the Doka Ready-to-Use Service will save both man-hours and space on the site.

Doka field service

Our supervising foremen and engineers will advise you right the way through from when the formwork is assembled to when it is first used, up to and including the typical operating sequence, and give the forming crew introductory training on-site.

SKE 50 systemLoad capacity: 5 tonnes per bracket

The SKE 50 system is the ideal solution for the majority of climbing assignments. Because it is a single-unit climbing scaffold, the brackets and auto-matic climbers can be freely positioned.Casting-section heights: up to 5.50 m

Formwork systems:

� FF20 and Top 50 timber-beam formwork� Framax and Alu-Framax framed formwork

SKE 100 systemLoad capacity: 10 tonnes per bracket

When exceptionally tough requirements are made of the automatic climbing technology, the SKE 100 system really comes into its own - with its high 10t load capacity and a platform system that allows work to be carried out simultaneously at several levels. The extremely strong brackets permit varia-ble and – where needed – extra-wide cantilever cen-tres.Casting-section heights: up to 5.50 m

Hydraulic systemThe SKE automatic climbers are "jumped" with the aid of a hydraulic ring-main system. The ring-main system is based on a stationary hydraulic unit designed to provide uniform, simultaneous drive for up to 30 automatic climbers. The number of automatic climbers that can be raised jointly in one climbing cycle must be appropriate for the structure and the construction workflow, and not so many that it is no longer possible to "keep track" of them all.

� A high number of cylinders can be operated simultaneously

� Open and closed ring-mains are possible- open: for a small n° of automatic climbers- closed: for a large n° of automatic climbers.

The pressure build-up takes place from 2 sides.� The hydraulic unit is equipped with cooling and

heating systems and a portable control panel� Can be combined with a radio remote-control

system

Hydraulic units

Number of cylinders that can be operated simulta-neously:

Note:

If the unit needs to be lifted, it should only be slung from, and lifted by, the crane hoisting lugs pro-vided.

Hydraulic ring-main systemInstallation principle

Ring-main system with stationary hydraulic unit. Suitable for driving SKE automatic climbers in an even, uniform way.

Open ring main

In this configuration, the Circular mains 6.50m are not routed back to the hydraulic unit.

Closed ring main

Both the pressure hoses and the return-flow hoses are routed back to the hydraulic unit here. This makes for a more uniform pressure build-up in longer hoselines.

Anchoring on the structure

Positioning point and suspension

point

Components:

Both the positioning points and the suspension points are prepared using one single type of cone, the Universal climbing cone (A) .

The Cone screw B 7cm (C) also fulfils 2 functions:� On the positioning point - for fastening the Uni-

versal climbing cone.� On the suspension point – as a safe means of sus-

pending the climbing unit.

Preferably, stop-anchors (D) are used, or – depend-ing on the characteristics of the structure – pigtail anchors (E) .

Anchoring systems

The decisive criterion for the choice of anchoring system is the tensile forces that will occur.

Suspension shoes

These ensure that the automatic climbers are safely suspended in all phases of the work.

Suspension shoe SKE 50 rigid

Is used for safe suspension of the climbing carriage and of the climbing profile.

Is fastened in the� Universal climbing cone using the � Cone screw B 7 cm.

Suspension shoe SKE 100

Is used for safe suspension of the climbing carriage and of the climbing profile.

Consisting of:� Suspension beam (L) and� Drop-in shoe (M)

The Suspension beam is fastened in the� Universal climbing cones using � Cone screws B 7 cm(2 of each per Suspension beam).

Preparing the positioning point and

suspension point

➤ Do not place concrete directly above the pigtail or stop-anchors.

➤ Do not allow the vibrator to touch the pigtail or stop-anchors.

These measures prevent the anchors working loose during pouring and vibration.

➤ Every time the Universal climbing cones are used, fit them with new sealing sleeves first.

9751-236-01

M

L

Warning!

➤ Always screw the pigtail or stop-anchor into the Universal climbing cone until it fully engages (i.e. up to the depth mark).Not screwing the anchor sufficiently far into the cone may subsequently lead to reduced load-bearing capacity and to the failure of the suspension point – resulting in injury and damage.

➤ Never weld or heat tie-rods - risk of frac-ture!

➤ For the positioning point and suspension point, ONLY use Cone screws B 7 cm (head of screw is red, to indicate its high load-bearing capacity)!

Make marks on the top edge of the form-work so that you can easily see where the anchoring points are during pouring.

� � The axis of the universal climbing cone must be at right-angles to the surface of the concrete – maximum angle of devia-tion: 2°.

� Tolerance for locating the positioning points and suspension points: ±1 cm in the horizontal and the vertical.



Positioning point: Standard solution with hole

B 7cm

a ... 35 to 45 mm

Tools needed: � Reversible ratchet 3/4"� Spanner for Universal climbing cone 15.0/20.0� Extension 20cm 3/4"� Box nut 50 (for Cone screw B 7cm)

Note:

The pigtail anchor must be facing downwards

➤ Fasten a packing plate (G) (e.g. Dokaplex 15 mm) to the form-ply (position as per project plan).

➤ Drill a diam. 30 mm hole in the form-ply (position as shown in the project plan).

➤ Push the Cone screw B 7cm (C) through the form-ply, screw it into the Universal climbing cone (A) and tighten it firmly.

➤ Screw the Stop-anchor or Pigtail anchor (D) into the Universal climbing cone (A) , until it engages (up to the depth mark) (F) .

Positioning point: With hole drilled through

form-ply and Positioning clamp M30

Because the hole only needs to be drilled with a diameter of 9-10 mm, the positioning-point can be relocated at smaller intervals than would be possi-ble with the Cone screw B 7cm.

Tools needed: � Reversible ratchet 3/4"� Spanner for Universal climbing cone 15.0/20.0� Extension 20cm 3/4"� Box nut 50 (for Cone screw B 7cm)� Reversible ratchet 1/2"� Extension 1/2"

➤ Drill a diam. 9-10 mm hole in the form-ply (posi-tion as shown in the project plan).

➤ Screw a Socket connector M30 (I) all the way into the Universal climbing cone 15.0 (A) and tighten it.

➤ Nail the Positioning disc M30 (J) to the form-ply, using 28x60 nails (position as per plan).


➤ Screw the Universal climbing cone (A) onto the Positioning disc M30 (J) and tighten it.

Before pouring

➤ Check all positioning points and suspension points once again.

Repeat use

Universal climbing cones are supplied with Sealing sleeves K (B) . Every time the Universal climbing cones are used again, fit them with new sealing sleeves first!

Suspension point

➤ Fix the Suspension shoe SKE (K) in the Universal climbing cone 15.0 (A) with a Cone screw B 7cm (C) . A tightening torque of 100 Nm (20 kg assum-ing a ratchet-length of approx. 50 cm) is suffi-cient.

Forcibly tightening the Cone screw B 7cm any more than this may cause damage and even cause the form-tie to break!

The only tool allowed to be used for screwing in and fixing the Cone screw B 7cm in the Universal climbing cone is the Reversible ratchet 3/4" in con-junction with an Extension 20cm 3/4" and a Box nut 50.

� Important!

It is not permitted to use the Positioning disc M30 more than once in the same position, as it cannot be fixed firmly and securely in the old nail-holes.

Platform scaffolds

Suspended platform SKE/MF 425The Suspended platform SKE/MF425 is suitable for pour-heights of up to 4.25 m and has 2 work-deck levels:One for operating the climbing unit (width 220 cm) and another for dismounting the Suspension shoes and for carrying out other finishing work (width 150 cm).

The Suspended platform SKE/MF 425 425 consists of:

Suspended platform extension SKE/MF 550

This is used for extending the Suspended platform SKE/MF 425 for dealing with pour-heights of over 4.25 m and up to 5.50 m. It is screwed onto the Con-nection profile / the Front suspension profile, between the platforms.

Pouring and intermediate platformsIn the same way as with the Climbing formwork MF 240, the pouring platform and any intermediate platforms needed for manipulating the anchors etc. can be constructed using e.g. the Screw-on access bracket MF75 or the Universal bracket 90.

Automatic climbing formwork SKE 50 with gallowsIn this variant of the automatic climbing formwork, the automatic climbers are only needed on one side of the wall. As in the standard variant, the formwork is permanently attached to the climbing scaffold and so can be plumbed and aligned very exactly. This means that the opposing formwork (sus-pended from the gallows on the other side) can eas-ily be aligned with the fixed formwork.The wide platforms on top of the gallows construc-tion greatly facilitate the preliminary reinforcement work, pouring, and equipment storage.

Variant 1Is mostly used for façades and walls that are poured ahead of (i.e. separately from) the floor slabs.

Typical cross-section:

Variant 2In this variant, the wall and floor-slab are cast in one single pour. By doing away with complicated floor junctions, this expedites and simplifies the con-struction sequence.

Loading dataIn line with standard building practice, the statical design for the SKE 100 automatic climbers must allow for two different load situations:

� Loads imposed in the statically anchored situa-tion, i.e. while construction tasks are being car-ried out.

� Loads imposed during climbing, i.e. while the connected platforms are being moved into their new working position.

Climbing phases

Schematic workflowAutomatic climbers can cover a wide area of practi-cal applications.Their modular design enables them to be combined in many different ways.This means that in some projects, they will be put together differently, and a different sequence of operations will be needed, from the schematic workflow shown here (e.g. for sloping walls).

� Shop drawings and assembly plans� Work instructions� Operating Instructions for SKE 100� Operating Instructions for radio remote-control

system� Operating Instructions for hydraulic unit� Any additional documents which may have been

drawn up by Doka for the project in question� Important note:

All assembly and disassembly work, the first time of putting into service and the first typ-ical climbing sequence must be supervised by a Doka supervising foreman or an author-ised technician.

Read and observe the following documents:

Platform scaffold SKE 100Example – pour-heights from 3.86 to 4.45 m

The Platform scaffold of the SKE 100 is the basis for a complete, self-contained platform system. The number of platform-levels varies from project to project.Even when the formwork is being removed and re-set, all the platform levels are always enclosed by all-round handrails. Forming and reinforcement-placing operations can be carried out above one another, at the same time.The Platform scaffold can be freely positioned, irre-spective of how widely or closely the Climbing units are spaced. This enables it to be optimally adapted to suit the requirements of the structure.

Folding platformThe folding platform widens the platform-level, making reinforcement work much easier. To make it possible to manoeuvre the climbing profiles into place, and to transport materials downwards, the platform can simply be swung up out of the way.
