t
The mast can be easily and safely
secured at the base and guying points
immediately after it has been lifted
into position.
t
Any extra rigging that is required for
the lift only, can be removed after the
mast is in place.
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:
t
The crane has enough weight and
height capacity to safely do the job.
t
There is nothing overhead that will
obstruct the lift.
t
Everyone involved in the lift knows
what has been planned and how the
lift is to be performed.
t
The mast is securely footed and cannot
move out of control during the lift.
t
Any guying has been properly secured
at the mast anchor points.
t
The downconductor has been correctly
terminated and the structure bonding
cable has been attached to the
termination.
t
The downconductor can not be
damaged at the base of the mast while
lifting, ie: 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.).
