Diagram to determine distance to leaning surface
The minimum lengths can be read off the table.
It is generally recommended to use the next
longest ladder length of the Hymer range.
Leaning angle 70 o
(our recommendation for rung ladders)
= vert. height x factor 1.064
Leaning angle 75 o
(still permitted for rung ladders)
= vert. height x factor 1.035
Leaning angle 68 o (stepladders)
= vert. height x factor 1.080
Leaning angle 60 o (steps)
= vert. height x factor 1.155
Leaning angle 45 o (steps)
= vert. height x factor 1.414
Example:
vertical height (upper leaning point) = 7.00 m
when using a rung ladder: 7.00 m x 1.064
(70 o leaning angle) = 7.45 m (minimum size)
