CAUTION
Step 9 will keep the loose chain from bunching up between the main and sliding beams as the sliding
beam moves outward. Lack of tension on the chain could cause the beams to bind and prevent the
sliding beam from moving.
9.
Thread loose end of chain (13) through opening vacated by idler gear, and out of end of main beam (5), along wall of
sliding beam (9) until full length of chain is positioned against sliding beam wall.
10.
Attach a ratchet strap to spreader chain, and to end beam tee, and apply tension to chain (13), to allow chain to move
with sliding beam (9), while it is being slid out to access chain anchor (22) attached to inside of beam.
