ACS Core 400 Self-Climbing System

Achieve shorter cycle times with hydraulic climbing.

The ACS Core 400 Self-Climbing Formwork System for cores has been specifically designed with the US high-rise market in mind. The system features a high-capacity single-stroke cylinder that climbs to the next level in just 20 minutes. Fewer brackets, anchors, and overall parts result in faster cycling times with less labor. Additional benefits include preassembly of both the internal and external platforms, as well as increased safety and reduced crane time when installing the external suspended platforms.

Furthermore, the ACS Core 400 can support large concrete placing booms, and its increased reach allows for simultaneous pouring of slabs and walls.

The ACS Core 400 system is optimized for large high-rise cores with significant cell dimensions and wall heights ranging from 2.70 m to 4.85 m (~16 ft.). This system can be climbed continuously in one stroke, enabling extremely short cycle times with minimal labor requirements.

The ACS Core 400 is primarily used with the Girder Wall Formwork VARIO GT 24, along with specially developed Shaft Corner and Stripping Elements. The system can be stripped either manually or hydraulically with the push of a button. Alternatively, the climbing system can also be combined with panel formwork MAXIMO or TRIO.

The long-stroke cylinders used have a lifting capacity of 40 tonnes. A systematic oil flow check ensures synchronous climbing of the entire internal and external formwork, even with high load differences. The cylinders can be controlled individually or simultaneously from a central location at the pump.

Spacious and particularly stable platforms provide safe, comfortable working areas with the necessary load-bearing capacity for material storage.

Comfortable, highly load-bearing working platforms

Spacious roll back area for the formwork and large platforms on all levels create optimal working areas
Economical anchor technology

Only 2 anchor points per bracket – the climbing bracket re-uses the anchor hole of the working bracket as the system climbs to the next level, thus saving a lot of labor time
Quick, safe climbing in one lift

Synchronous, single stroke climbing without any unsecured building edges
