Rigging and Lifting
The steel cone is to be lifted by the points at the top, separately and individually from the fan assembly.
Polyethylene nozzles do not have lifting points.
If needed, attach polyethylene nozzle to fan or stack prior to lifting
and use component lifting points.
Fans and bypass air plenums (BAP) should be disassembled prior to lifting and lifted individually. Fans and BAP are
to be rigged and moved by the lifting points provided or by the skid when a forklift is used. Location of the brackets
varies by model and size. Handle in such a manner as to keep from scratching or chipping the coating. Damaged
finish may reduce the ability of the fan to resist corrosion. Spreader bars are recommended to prevent damage to
the unit. Failure to use spreader bars may result in damage which becomes the installer’s responsibility.
1. Before lifting, be sure that all shipping materials have been removed from the unit.
2. Use standard lifting and rigging practices.
3. All lifting brackets on each unit must be utilized at the same time.
4. Fan to be kept level during lifting and installation.
5. Spreader bars must span the unit to prevent damage to the unit by the lifting cables.
6. Always test-lift the unit to check for proper balance and rigging before hoisting to desired location.
7. Never lift unit in windy conditions.
8. Preparation of roof opening should be completed prior to lifting the unit onto the roof.
9. Use well-padded chains to protect the unit from damage.
