Rigging the Bottom Section: Standard Lift
Lifting devices are located in the lower corners of the unit as shown in Figures 2 and 3. The hook of the crane must be a minimum
dimension of “H” above the lift point to prevent undue strain on the lifting devices.
See Table 2 for the minimum “H” dimension. Bolt the bottom section to the steel support before rigging the top section of the unit.
The unit lifting devices should not be used for extended lifts or where any hazard exists unless safety slings are employed under
the section.

Important: The lifting devices should be used only for lifting where no danger exists and for final positioning of the
section. For extended lifts, safety slings should be provided under the section as described on page 4.
