Self climbing formwork

Automatic, safe and reliable.‎
The ATR is a self-climbing formwork systemthat, driven by hydraulic and mechanical mechanisms, enables large sets of formwork to be lifted simultaneously without needing a crane.‎ Climbing is performed by means of the subsequent mast elevation and the climbing bracket-formwork-set erection along the wall surface.‎

- Self-climbing bracket ATR-B
Self-climbing bracket configuration where the formwork panel is stripped with roll-back carriages (70 cm) on the bracket itself.‎ It is also equipped with components for horizontal and vertical plumbing and positioning of the formwork.‎ It features two platforms: main working platform (2.‎ 5 m width) and control platform for the operation of the hydraulic system.‎ Moreover, three optional platforms for pouring, items recovery and other tasks can be installed.‎

- Self-climbing narrow bracket ATR-N
It is used in narrow shafts between walls with widths of 1.‎ 75 to 2.‎ 5 m where the ATR-B bracket cannot be used.‎ The formwork hangs from an upper structure (outrigger) enabling stripping, retraction and positioning works.‎

- Self-climbing platform ATR-P
Platforms used in shafts where for reasons of dimensions, loads or geometry, a platform system performs better than self-climbing brackets.‎
Structure based on MK System.‎ It can adjust to different geometries and be fitted with different formwork stripping systems (carriages or outrigger structures).‎ Structures for the support of auxiliary elements such as concrete placing booms and small cranes can be assembled to this system.‎
