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.

Overview

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

Variations

ACS R Self-Climbing System 

standard system with carriage and open formwork at the top for easy installation of the reinforcement

ACS P Platform System 

for high-rise building cores constructed in advance and tower-like structures with generously-sized storage and working areas

ACS G Realization with Gallows 

for concreting walls and slabs in one pour or for circular structures; both formwork sides are attached to the cantilevered gallows

ACS V Adjustable Version

for inclined structures such as bridge pylons or piers, with platforms always in a horizontal position

ACS S Shaft Formwork 

for stairways or small elevator shafts with a single climbing device positioned in the centre

ACS C Core Formwork 

for moving large-sized core formwork core including concrete placing boom and site equipment

I have already been working with PERI systems for many years and I am convinced that the ACS Climbing System and the VARIO Wall Formwork are the optimum solution. ACS enabled us to reduce the build time. In my opinion PERI offers the best formwork systems in terms of technology.

PERI´s ACS system has once again proved its uniqueness. We can safely and quickly realize our very complicated core wall as well as in a very high quality with the ACS without having to utilize the crane. This is a big advantage on our construction site.

The pylons of the 3rd Bosphorus Bridge are unique and extremely complicated due to the inclined conical shape and the numerous embedded items. PERI ACS system was the right decision for this one of a kind bridge project because of the huge experience of PERI. Getting a competent and comprehensive support inside our tight schedule and providing completely safe working platforms at all levels and at any height was other positive aspects of PERI ACS system.

We are absolutely satisfied with the PERI systems and the comprehensive service which helped us with proficient engineering, logistics and jobsite support to successfully implement the project. We are able to work safely and with minimum crane utilisation with SKYTABLE and ACS – thus we need less than 4 days for one storey.

This project would not have been possible without the PERI ACS self-climbing technology. It is a great and absolutely safe system. Also the cooperation with PERI is again and again ideal.

We are extremely satisfied with the PERI systems and the efficient engineering – we were able to considerably accelerate the climbing cycles thanks to ACS. Despite the great height, we were able to work safely on the working platforms. Furthermore, we achieved excellent concrete surfaces, our customer is very satisfied.
