Cooling-tow­er formwork SK175

The self-climbing formwork for cooling towers

This cooling-tow­er formwork is a ful­ly mech­anised, self-climbing large-area formwork sys­tem. It max­imis­es ra­tio­n­al­i­sa­tion and min­imis­es man­u­al labour – af­ter a short fa­miliari­sa­tion pe­ri­od, the crew will soon be ac­com­plish­ing the cast­ing sec­tions in a 1-day cy­cle.


Com­plete safe­ty
for your site crew 

Safe­ty in all phas­es of the work

  • even at great heights in strong winds, as the formwork is al­ways firm­ly at­tached to the struc­ture
  • due to its te­le­s­cop­ic work­ing plat­forms – th­ese are railed-in and ga­p­less even while climbing is in progress, and so pro­vide a safe work­ing en­vi­ron­ment at all times
  • thanks to op­ti­mal­ly adapt­ed platform widths and in­te­grat­ed lad­der sys­tems

Rapid work­ing
in a con­trolled se­quence 

Op­ti­mised formwork con­cept for fast forming-times

  • large-area formwork gangs, mak­ing the sys­tem much sim­pler to op­er­ate and clean
  • as the in­cli­na­tion of the whole scaf­fold can eas­i­ly be ad­just­ed from one cen­tral spin­dle
  • thanks to the built-in re­in­force­ment hold­ers in the scaf­fold, which make it a quick and easy job to place the re­in­force­ment

Out­s­tand­ing cost-ef­fi­cien­cy
for your cooling tow­er 

A cost-ef­fec­tive so­lu­tion is fa­cil­i­tat­ed by

  • all-round plat­forms that al­low op­er­a­tio­n­al se­quences to be 'de-linked'
  • a very small num­ber of form-tie points per square me­tre
  • con­sis­tent­ly high con­crete qual­i­ty, thanks to the steel form-fac­ing
  • large-area formwork gangs for a cast­ing-sec­tion height of 1.50 m
  • the prac­tice-ori­ent­ed pro­ject plan­n­ing pro­vid­ed by Doka



Cooling-tow­er formwork SK175

This special cooling-tower formwork for hyperparaboloidal natural draught cooling towers was developed in the course of several years' work on the basis of the Automatic climber SK175. The high capability of this system has been confirmed by its use on very many construction sites.

The platform sys­tem for a stream­lined work­flow

The permanently mounted telescopic platforms ensure that there is an uninterrupted circumferential walkway all the way around the cooling tower at all times, even during the entire climbing operation. This detail makes a crucial contribution towards safe – and thus troublefree – working.


High adapt­a­bil­i­ty

Down to a vertical radius of 70 m, the cooling-tower formwork can climb through curves unhindered. Up to a 22° angle of inclination, the formwork is adjusted simply by the platform system, with one spindle per bracket.

Plac­ing the re­in­force­ment

Working from the top platform, the reinforcement can be placed a day in advance. The reinforcements are held in position during placement by reinforcement holders mounted on the scaffold.

A well thought-out sys­tem

The four platform levels make for a well-ordered construction workflow and safety during all operations.

Electromechanical lifting systems are used to raise the formwork, making it completely independent of the crane.

Steel formwork elements with compensating elements on both sides provide adaptability in the horizontal and make for constant concreting results all the way through to the very last casting section.

To allow the formwork elements to be quickly cleaned, they are designed so that they can be rolled back approx. 60 cm from the concrete. The formwork is opened with the aid of a spindle, and rolled back by hand on rollers.
