MULTICRAB - TECHNICAL INFORMATION - 2023 140 TECHNICAL DATA DESIGN CHART FOR CIRCULAR SCAFFOLDING Conditions and assumptions of the study: •Straight sections = standard grid sections •All straight sections are the same length •0.70 m wide scaffolding •Intersections with VARIOPAN and guardrail with 1.50 m MULTICRAB ledgers and toe boards. •Stops or anchors on all sections at a pitch of 4.00 m in height Layout with single sections Layout with double sections A special study is required for: •containers less than 7.00 m in diameter, which require a “hybrid” layout (sections of different sizes), •containers more than 30.00 m in diameter, which require stabilisation or specific structural reinforcements. The forces on the end stops must be evaluated according to: •the geographical area where the structure is located, •the cladding fit on the structure (bare structure or equipped with nets or canvas cover).
