Specifications and load capacity M I L L S T O U R : S H O R I N G T O W E R F O R C I V I L E N G I N E E R I N G W O R K S 10 > Frame strength The strength of each frame under a horizontal force H was determined by testing. It is: - 4.5 kN for 1.00 m spacing. - 6 kN for 1.60 m spacing. - 6.75 kN for 2.20 m spacing (half the ultimate load limit). > Base ledger strength The maximum load on the scaffold planks resting on the base ledgers is given in the following table in kg/m². > Maximum load on standards The maximum load on each standard is: - MT65 at 1.00 and 1.60 m spacing: 6.5 t - MT65 at 2.20 m spacing: 6 t - MT100 at 1.00 and 1.60 m spacing: 10 t These loads are based on official tests carried out according to NF P 93-550. The towers are tested with the screw jacks and heads fully extended and with a horizontal load at the head of 2% of the vertical load. The maximum operating load is half the ultimate load limit. > Specifications of the main components: Component Geometry Rp A I S (mm) (MPa) (cm 2 ) (cm 4 ) (cm 3 ) Standard MT65 fixed height standard Tube Ø60.3x3.2 280 5.74 23.47 7.78 MT65 telescopic standard Tube Ø48.3x6.0 355 7.94 18.04 7.52 MT100 fixed height standard Tube Ø76.1x4.5 320 10.12 65.12 17.11 MT100 telescopic standard Tube Ø60.3x6.3 355 10.69 39.49 13.10 Frame Ledger and upright Tube 30x30x2 280 2.24 2.91 1.94 Diagonal brace Tube Ø26.9x2 280 1.57 1.22 0.91 Base ledger Tube 50x30x2 280 2.94 9.54 3.81 Adjustable heads and screw jacks MT65 screw Ø33 studding 360 8.55 5.82 3.52 MT100 screw Ø40 studding 360 13.85 15.27 7.27 Please contact our technical personnel for advice and solutions. - Maximum deflection = L/200 * Access for personnel without tools.
