BOOM ASSEMBLY
(See figure 2A.) First mark the center of the 2.832” O.D. boom coupler
Slide both of the
20’ sections of 3” O.D. tubing over the ends of the coupler so they both butt at the coupler center.
(See figure 2B.) Mark the center of the boom to mast plate. Center the plate (P04) on the boom and
secure with four of the 3” U-bolts (U03) and saddles (S03) and eight of the
lockwashers (N02) and
hex nuts
Avoid over-tightening the U-bolts as doing so may crush and weaken the boom. Now,
reverse a 3” U-bolt so that it points away from the boom to mast plate. Slide on a 3” saddle, followed by
the vertical guy support, then secure with
lockwashers and hex nuts.
From the roll of guy cable
cut two lengths 2’ long. Take the two
(N18) and pass
one end of the cable through the eye of the bolt and wrap. Pass the opposite end of the cable through the
hole in the egg insulator
and adjust so that the length of cable between the eye of the
and the
egg insulator is then wrap the cable. Make two of these, then place the
onto the guy support with
one nut inside and the other nut on the outside of the vertical guy support. Tighten only finger tight at this
time.
