Rigging and Unit Handling

￿WARNING Improper Unit Lift!

Test lift unit approximately 24 inches to verify proper center of gravity lift point. To avoid dropping of unit, reposition lifting point if unit is not level. Failure to properly lift unit could result in death or serious injury or possible equipment or property-only damage.

￿WARNING

Lifting Equipment Capacity!

Ensure lifting equipment capacity exceeds unit weight by an adequate safety factor to prevent injury, death, or unit damage.

Before lifting the unit or modular component, determine the approximate center of gravity for lifting safety. See Figure I-PC-5 for assembled modular units and Figure I -PC-6 for split-apart units. The center of gravity may vary slightly within the gravity block depending on unit options.

Always test-lift the unit to determine the exact unit balance and stability before hoisting it to the installation location. See Figures I-PC-7 and I-PC-8 for typical rigging procedures and proper rigging equipment usage.
