Touréchaf shoring Ø 60 Crabtour shoring Ø 60 Crabétai shoring Ø 57 Multicrab Scaffolding Ø 49 Crabescal Staircase Hélicrab Staircase Connection with Multicrab Crab equipment The Crab system consists of a self-locking wedge key attached to a stirrup. Once a ledger comes into contact with a stirrup, the wedge pivots automatically to form an instant connection. A single blow to the wedge key ensures the strength of the connection. When wedging is carried out along the main axes, it is guaranteed that the ledgers will be connected at right angles. A ledger may also be installed in any direction, without any dead angles. The Crab node can be used to fit 8 components simultaneously: 4 ledgers and 4 diagonal braces. Entre-axes poteaux 1,00 m Poteaux Ø 49 mm Poteaux Ø 57 ou Ø 60 mm The Crab system allows having a single centre distance, irrespective of standard diameter (49, 57 or 60 mm). This feature means that identical ledgers, diagonal braces and decks are used on all of our Crab equipment. The use of common scaffolding and shoring components makes equipment management easy. The Crab system is able to mix and match standards with different diameters according to the load-bearing requirements. For example, Ø 57 mm Crabétai standards can be used for the bottom of very tall Ø 49 mm Multicrab scaffolding. 16
