O v e r h a n g ( PA F ) 3 5 Assembly with compressive diagonals Assembly with tensioning diagonals ( preferable) Recommendations Overhang projections must be constructed from stabilized scaffolding. On a secure deck, the erectors construct an assembly of ledgers, diagonals and bases for a cantilevered assembly with either tensioning (preferable) or compressive diagonals . PLEASE note that parts used to create an overhang must be carefully checked before assembly, as they are subject to great stress. All overhanging structures, suspended or self-supporting, must have their uprights linked with two bolts. Put in place 2 diagonals on the lower nodes . Projecting the overhang. Keying ledgers at deck level. Lay decks widthwise , then the standards, guardrails and toeboards. Put in place 2 diagonals on the upper nodes. Projecting the overhang. Keying ledgers at deck level. Lay decks widthwise, then the standards, guardrails and toeboards. Dismantling: dismantle the tower in the reverse order of assembly. See the assembling and dismantling recommendations on page 10.
