3.2.6 Lifting
Units are to be lifted by the points specified and designed to lift only the specific units' dry weight. These lifting points
are suitable for either Crane or Helicopter lift with suitable spreader bars. The unit cabinet is lightweight aluminium and
at no point should the lifting slings or spreader bar contact the cabinet, failure to comply will permanently damage the
case.
Lifting point securing bolts and lifting eyes must be inspected for prior to lifting to ensure all bolts are installed, of
correct tensile strength and are correctly tensioned. If any damage is observed, lifting points and/or eyes should be
replaced.
Below is a suggested lifting arrangement. Noting that the centre of gravity should be assessed for each unit prior to
lifting. By suitably qualified crane operator,
by contacting Seeley International.
