4 2 0 . 1 5 m l e d g e r 3 2 Example 1: downward load transferred from one standard to two standards Example 2: Inertia reinforcement Examples of using the 0.15 m ledger 0.15 m ledger The 0.15 m ledger allows: - link 2 standards. - strengthen the inertia of a standard by doubling it with another, but without load transfer in the stiffener standard. Mechanically, it transmits and takes up the same stresses as the other ledgers. Part number Description Weight (kg) 250201-1 0.15 m ledger 0.90 Shearing stress prohibited Example 3: assembling a sheet support side section with outer diagonals to avoid fitting rails between tube and couplers. If you want to double a standard to halve compressive stress, fix a tube and two couplers at the junction. Underneath, the 0.15 m ledger maintains the spacing between two standards and helps with erection. The 0.15 m ledger facilitates erection but the load is transferred by the tube stiffener and couplers. F F/2 F/2 01.11.17 T e c h n i c a l i n f o r m a t i o n
