Access ways
Access is usually provided by means of HAKI UTV AL stairways that are fitted to the
outside of the scaffold using components designed for this purpose. When an external
stairway is fitted in accordance with the directions on page 13, the loads on standards
should not be reduced.
Alternatively, a HAKI tower scaffold may be used, see User´s Manual HAKI Stair Tower.
Ascent via ladders may be arranged by means of HAKI decking units with trapdoors and
ladders, or HAKI STV ladders.
Lattice beams
Lattice beams of aluminium
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 standards using SW 48x48
swivel couplers. The height is adjusted so
that the decking is horizontal when this is
installed.
The lattice beams must be braced against
lateral movement using a diagonally rigid
framework of standards and beams or
tubes and couplers.
When erecting as in the illustration with
ledger beams and horizontal diagonals,
the greatest permitted load on a standard
is 14.7 kN at the centre of the lattice
beam. Vertical diagonal bracing must be
carried out between the outer standards in
both bays beside the beam.
