Rigging Coil/Fan Section - EVAPCO ATC-E Rigging And Assembly Instructions

ATC-E, ATC-ES, ATWB, eco-ATWB and eco-ATWB-E Evaporative Condensers and Closed Circuit Coolers

Rigging Coil/Fan Section

Four lifting ears are provided in the lower corners of most coil/fan sections for lifting into final position. Some 18' (5.5m) long
sections and longer will have two additional lifting ears in the middle of the section. (See Figures 6a and 6b.)
Use all lifting ears. A spreader beam must be used for lifting the top section(s) as shown in Figures 6a and 6b.
The hook of the crane must be a minimum dimension "H" above the lifting ear to prevent undue strain on the lifting ears. See Table
3 for the minimum "H" dimension. These lifting devices should not be used for extended lifts or where any hazard exists unless
safety slings are employed under the section. (See "Extended Lifts" for proper arrangement.)
Note: For 7' (2.24m) and 8.5' (2.6m) wide models, mount the external motor prior to rigging as detailed in the "External Motor
Installation" section.
