ACS Self-Climbing System

ACS P - the solution for advancing cores of high-rise buildings and tower-like structures - combined with ACS G. Both formwork sides are movably attached to the cantilevered platform beams.
The Self-Climbing System ACS-R with the one-sided reinforcement scaffold in advance.
The ACS self-climbing versions can also be combined. Three variants are formed here – combined with the VARIO GT 24 girder wall formwork and the TRIO panel formwork – crane-independent climbing units.
ACS V can be adjusted to accommodate forward and reversed-inclined piers and pylons. Regardless of the angle of inclination, the working platforms are always in a horizontal position.
For the external walls of this 47 m x 43 m building core, the ACS R variant provides the optimum solution.
With the ACS self-climbing technology, the concrete placing boom and suspended stair towers can also be moved upwards with any crane assistance.
For the construction of this 90 m high pylon, the RCS and ACS climbing systems were combined.
The PERI climbing mechanism is at the heart of all ACS variants. The positively-driven pawl system operates automatically and safely with a lifting speed of 0.5 m/min.
The high load capacity of the building authority approved PERI climbing anchors allows climbing to take place shortly after concreting. The optimal climbing shoe and anchor type are determined for each individual project.


The range of ACS self-climbing variants for facades, building cores, shaft structures as well as inclined bridge pylons make the construction of high concrete structures extremely fast, cost-effective and safe. The climbing units comprising wall formwork and platforms are moved from floor to floor by means of integrated hydraulic systems. The efficient sequence of operations facilitate a very high level of productivity and exceptionally short cycle times. Simultaneous climbing of several climbing units ensures fewer leading edges thus resulting in increased workplace safety.

Crane-independent, quick working operations
Shuttering, striking and hydraulic climbing in a very fast work rhythm

Weather-independent working
Comfortably-designed platforms with enclosures protect site personnel against wind and weather

Stable working platforms
Working platforms can accommodate high loads, e.g. arising from material storage or placing boom masts

Technical Details

  • Rail-guided, safe climbing procedure without a crane
  • Climbing device with 100 kN lifting power
  • Positively-driven and jerk-free climbing
  • 0.4 m/min effective climbing speed
  • Climbing can take place outside of normal working hours thanks to the almost silent climbing hydraulics
  • Weather-independent working operations with enclosed working platforms
  • Climbing shoes and anchor types optimized for project-specific factors such as building structure, load, wall thickness and required concrete strength
  • Large climbing units reduce the number of lost anchor components
