Handling
Handling of all air moving equipment should be conducted by trained personnel and be consistent with safe handling practices. Verify
the lift capacity and operating condition of handling equipment. When using hoisting equipment, only qualified and trained personnel
should operate the equipment.
Units shipped completely assembled may be lifted with slings and spreader bars. (Use well-padded chains, cables or nylon straps,
rated to lift the required weight.) On most units, lifting lugs are designed to protect the fan and fan housing from damage. Never lift a
fan by the inlet or discharge flange, shafting or drives, impeller, motor or motor base, or in any other manner that may bend or distort
parts. Never lift with slings or timbers passed through the fan inlets.
Model PC fans:
The fan may be lifted by the lip of the shroud. This can either be done manually
(total fan weight is between 50 – 70 lbs.) or with a minimum four-point hook system. Take
precautions to not cause any damage to the shroud.
Model PCU fans:
All Sizes:
Fans may be lifted using hooks around the four (4) horizontal support posts with a
minimum of four lifting straps with spreader bars to ensure that no contact is made with the
motor housing.
Sizes 122 and greater:
An alternative method for direct drive units between Sizes 122 and 165 is
to utilize the lifting holes located on the motor support plate within the housing. To lift the unit,
four straps and hooks should be used to lift by all four points.
Model PCUB fans:
Two lifting lugs located on the bearing support plate provide easy access lifting
points. There are also four holes located on the drive frame bars from which the fan can be lifted.
Wall Mount Fan:
Use two lifting straps around the shroud of the fan. One should be located
around the neck of the shroud and the other near to the shroud lip.

1. Maintain handling equipment to avoid serious personal injury and do not stand under
the load.
2. If supplied, only use the provided lifting lugs to lift the equipment.
3. Ensure that the lifting equipment is rated for the capacity to be lifted.
