Permissible construction heights for HAKI Ram Aluminium
LOADING CONDITIONS
Permissible loads on standards
The permissible load on a standard is 14.5 kN (4.2 kN). For HAKI Ram of aluminium, a
permissible load on a standard of 7.6 kN is applicable in structures where a maximum of
25% of the uniformly distributed working load may consist of material stored on a work
platform (load class 3).
The support surface must be capable of withstanding a design load of 29.3 kN (17.2 kN)
per standard.
Permissible construction heights
The tables are valid for HAKI Ram scaffolding with bay widths 700 mm, bay lengths
3050 mm, lift heights 2.0 m, vertical distances between ties of 4.0 m, and erected using
HAKI Ram decking units.
Work must only be carried out on one level at a time.
Other bay lengths and load classes will have an effect on the permissible construction
height. Please contact HAKI’s technical department in these cases.
