97 MULTICRAB - TECHNICAL INFORMATION - 2023 MULTICRAB ASSEMBLY Doubling a standard to clear an obstacle Load transmitted limited to 1500 daN Load transmitted limited to the upright's capacity The number of tubes and couplers (TC) defines the transferable load. If the assembly is constructed with one stiffener on each side of the gap , the transmitted load will be 1500 daN (coupler sliding). On the other hand, if two stiffeners are fitted on each side , the transmitted load will equal the standard's maximum admissible load. TC: tube and coupler stiffener with 4 bolts Assembling a sheet support side with outer diagonal brace to avoid fitting rails between tube and couplers This kind of assembly is prohibited because the 0.15 m ledger does not transfer the load in the added standard. 1 2 1 2 TC TC TC TC TC TC
