• The downconductor can not be damaged
at the base of the mast while lifting
(maintain a minimum bending radius of
500
mm (
20
in.)) or can not be damaged
as a result of dragging over rough or
sharp surfaces during the lift.
• Any extra rigging that is required for the
lift only, can be removed after the mast is
in place.
• The mast can be easily and safely
secured at its base and guying points
when it is lifted into position.
• Any guying has been properly secured at
the mast anchor points.
• The downconductor has been correctly
terminated and the structure bonding
cable has been attached correctly.
• The nVent ERICO Dynasphere terminal is
NOT used as a slinging point.
• When slinging the mast, ensure that the
slings or ropes can not foul the nVent
ERICO Dynasphere terminal.
• When lifting the mast, the downconductor
is tied off to the mast as well to remove
any strain on the downconductors
termination to the nVent ERICO
Dynasphere terminal.
