Pink Denotes calculation based on lateral support from adjacent frame in the ‘in line’ frame direction. Contact us for calculations if there is no lateral support.

Note – When used with Baypole Jacks the maximum loading is capped at 2 tonnes per pole. Frames screwfixed to coupler at 250mm centres.

Pink Denotes when used with Baypole Jacks the maximum loading is capped at 2 tonnes per pole.

Note – We truncated down the I-values to include a safety factor within this calculation. Calculations assume that the frame adapter is fixed to frames at 250mm centres and assembly is fixed from Baypole to frame at max 250mm centres.
