Simplified HYMER formula *

*) This may vary depending on the type of ladder. Please observe the information in the technical tables on this website.

 

What size/length is required ?

When selecting the size/length of ladder, it should be ensured that:

Sicherheitshinweise zur Anlegeleiter Leaning ladders may only be climbed up to the fourth step/rung from the top in order to provide suffi  cient hold.
Sicherheitshinweise zur Stehleiter Double-sided accessible step ladders may only be climbed up to the third step/rung from the top in order to provide suffi  cient hold.
Sicherheitshinweise zu ausziehbaren Stehleitern Combination ladders in position mode «step ladder with attached extension ladder» may only be climbed up to the fifth rung from the top.
Sicherheitshinweise zu Stehleitern mit Plattformen

The size of step ladders with platform and platform ladders must be selected so that the user can reach the maximum required working height without having to stretch outwards from the platform.

Ellenbogenmethode The elbow method helps to determine the correct inclination angle.

 

Calculation of ladder length with known vertical height

Calculation of ladder length

The minimum lengths may be found in the table. It is generally recommended to use the next longest ladder length of the HYMER range.

Example for calculating minimum ladder length:
