MULTICRAB - TECHNICAL INFORMATION - 2023 96 0.15 M LEDGER Transfer of the vertical load from one standard to two standards Inertia reinforcement If you want to double a standard to halve compressive force, fix a tube and two couplers at the junction. Underneath, the 0.15 m ledger maintains the spacing between two standards and helps with assembly. The 0.15 m ledger facilitates assembly but the load is ensured by the tube and coupler stiffener. With the 0.15 m ledger, one can: •connect 2 standards. •strengthen the inertia of a standard by doubling it with another, but without load transfer in the stiffener standard. EXAMPLES OF USING THE 0.15 M LEDGER Mechanically, it transmits and takes up the same forces as the other ledgers. INFORMATION Shearing force PROHIBITED F F/2 F/2 Contact our design offices for more complex structures. 2-bolt junction couplers and CRAB couplers are used for interconnecting with low load take-up (connections between towers, guardrails). For high load take-up, use 4-bolt couplers.
