Technical information Crab range

Admissible loads of the standards Compressive (kN) For façade scaffolding anchored in a zigzag pattern with one side section out of two, in accordance with standards NF EN 12810 and NF EN 12811: • every 8.00 m Q = 18.69 kN in Multicrab Q = 30.50 kN in Crabétai • every 4.00 m Q = 24.44 kN in Multicrab Q = 39.21 kN in Crabétai For other types of scaffolding, the loads depend on the ledger height in correlation with the triangulation: Upright Buckling length of 2.00 m Multicrab 24.44 Crabétai 39.21 For other configurations, calculations carried out by a competent design and engineering firm are required on a case-by-case basis.
