Load Tables

Safe load tables are provided in a unique format for easy comparison and cost optimisation. Load tables assume an even distribution of load across the width of the ladder fixed in a horizontal plane, and that the loading is similar on at least two or more continuous spans. For non-uniform loads or spans/loadings outside the scope of the tables, please contact Metsec for advice.

‘s’– maximum spacing of supports in metres
‘d’– maximum deflection in end span in mm
‘dp’– allowable deflection (span/200) in mm
‘w’– safe working load in kg per linear metre

Example

Load required = 100kg per linear metre

3. 125mm deep ladder will span up to a maximum of 5.321m with a deflection of 21.4mm
4. 150mm deep ladder will span up to a maximum of 6.000m with a deflection of 21.8mm
