It may be necessary to use a gin pole
arrangement to assist when lifting the mast,
especially if the mast is over
6
m (
20
ft.)
in height or it is being lifted from a sloping
surface (typical arrangement shown below).
When using a crane to lift the mast into
position, ensure that:
• The crane has enough weight and height
capacity to safely do the job.
• There is nothing overhead that will
obstruct the lift.
• The downconductor can not be damaged
at the base of the mast while lifting, i.e.: if
the cable exits from the mast base it must
be protected and not used as the pivot
point for the mast. Maintain a minimum
bending radius of
500
mm (
20
in.).
• The mast can be easily and safely
secured at the base and guying points
immediately after it has been lifted
into position.
• Any extra rigging that is required for
the lift only, can be removed after the
mast is in place.
