Application
• Fastening of cable trays, pipes on a T-Post support, which is fastened on a
horizontal structure
• Support is fastened by two / four X-BT-MR (horizontal distance x)
• L1 is the total width of the T-Post, L2 is fix set to 1000 mm
• Load F is the acceptable total load (all dead load including)
Boundary conditions
• These values are ONLY reflecting capacity of X-BT-MR threaded stud.
Structural analysis of support / structure is NOT in Hilti scope. See the detailed
statements in disclaimer — 2018/05/04
• 2 Load cases: load asymmetric acting in the center of one arm only,
30% acting as horizontal load
