Extended Lifts
Important: The lifting devices and “U” bolts should be used for final positioning only and for lifting where no danger
exists. If they are used for extended lifts, safety slings should be provided under the sections.
Safety slings and skids must be removed before final positioning of the unit.
The preferred method for extended lifts is to use slings under the unit, as shown in Figure 14 below. Spreader bars should always
be used between the cables at the top of the section to prevent damage to the upper flanges.
