Rigging
Before proceeding, refer to tables in Unit Weight section
for typical unit operating weights and
for
rigging drawing.
1. Remove the shipping crate from around the unit.
2. Rig the unit as shown in
. Attach
adequate strength lifting slings to all four lifting
brackets in the unit base rail. Do not use cables, chains,
or slings except as shown.
3. Install a lifting bar, as shown in
, to
protect the unit and to facilitate a uniform lift. The
minimum distance between the lifting hook and the
top of the unit should be 7 feet.
4. Test-lift the unit to ensure it is properly rigged and
balanced, make any necessary rigging adjustments.
5. Lift the unit and position it into place. Remove fork
pockets prior to setting on the curb.
6. Downflow units; align the base rail of the unit with the
curb rail while lowering the unit onto the curb. Make
sure that the gasket on the curb is not damaged while
positioning the unit.
