P o d i u m 5 9 Composition of the decks The 5 kN/m 2 working load can be achieved if: 1-The stringers are in good condition and have the following characteristics: - Nature: category 2 resin ( σ e = 0.80 kN/cm 2 ) - 93 x 82 mm or 100 x 75 mm in diameter - Spacing: 0.35 m - Length = grid section length - 65 mm (Example: 2.00 m grid section, 1.935 m stringer) 2-The decks are made of combi plywood at least 18 mm thick. All podiums must be justified by a design note and working drawing. See the assembling and dismantling recommendations on page 10. The personal protective equipment must be attached on the Multicrab (see page 22) at least 1.00 m above the deck on which the operator is working, either around a ledger or through a stirrup. The stirrups at deck level must on no account be used for attaching.
