The following procedure describes using an overhead crane to position the crosshead. You can use any
device that can lift the weight of the load unit.

1. Center the overhead crane directly over the load unit.
2. Wrap lifting slings around the crosshead. Remove any slack in the lifting chains or slings while keeping
tension to a minimum.
3. Attach the lifting chains to the lifting rings, or wrap lifting slings around the crosshead. Remove any slack
in the lifting chains or slings while keeping tension to a minimum.
4. Remove the covers on the ends of the crosshead. The crosshead covers must be removed to access the
manual locking bolts and to clean and lubricate the bolts. Six 1/4-20 screws (three top, three bottom) on
each cover need 5/32 hex (not included). Hand-tighten when reinstalling the covers.
5. Loosen the crosshead locking bolts in 1/4 turn steps (counterclockwise). The following figure shows the
sequence of loosening the crosshead bolts.
