The Variant’s crane-climbing platform, combined with Variant wall formwork system is an efficient and safe way of shaft wall concreting. With use of stripping corners, the wall formwork can be easily closed and opened, simply by turning a spindle with a hummer. The whole set of wall formwork, shaft platform and additional suspended platform can be repositioned by one crane lifting. The main part of shat platform is a telescopic shaft beam. The item which bears the loads of formwork and working platforms, allowing an easy adaptation to any dimension of shaft structure. Moreover the telescopic shaft beam has a gravity pawl. Installed inside precast hole the pawl allows the platform to be shifted by crane only in one direction, upwards. The system serves as a support for wall formwork and as a safe area for maintenance of wall formwork.
Max. support load of the telescopic beam - 20 kN;
Live load on a shaft platform - 2 kN/sq.m.
Excellent adaptability to any shaft dimension;
Swift and precise formwork adjustment in all directions.
Reduced labor and crane times;
Fast and simple way of system pre-assembly and installation;
The entire unit can be repositioned safely and quickly in one piece.
Easy handling and planning:
Small number of different parts is used;
Any requirements for architectural concrete wall design can be met.
