LOADING CONDITIONS
Permissible loads on lattice beams when erected as described above.
Access ways
Access is usually provided by means of HAKI UTV stairways that are fitted to the outside of
the scaffold using extra frames (see erection 12).
Steel scaffolds having UTV stairways fitted externally may be built to a height of 37.5 m.
Alternatively, the HAKI Stair Tower may be used. See User’s Manual HAKI Stair Tower.
Lattice beams
Aluminium lattice beams
Aluminium lattice beams are
fitted in pairs on the inside
and outside of the scaffold.
Both the top and bottom
tubes must be fixed to the
frames using KV 48x48 right
angle couplers. The height
of the beams is adjusted
so that the decking will be
horizontal.
Frames with lattice beams
must be anchored at the
fixing points of the beams.
The lattice beams are braced
against lateral movement by
the fitting of RA 800 units
at a maximum of every third
metre as a basis for further
scaffolding.
