Step 2: Fasten teletubes to leg assemblies (AHA-6-#-# series; 6,000 lb. capacity models) or yokes (2,000 lb. and 4,000
lb. models).

NOTE: If you ordered a “Come-along” kit, perform Step 8 on p. 21 first.
Insert the teletubes through the sleeves of the leg assemblies or yokes. Align the 3
rd
pinhole in each teletube with the
pinhole in the leg assemblies or yoke as is depicted in Diagram 2A below.
Pin each teletube to a leg assembly through the same (3
rd
) pinhole with adjustment pins (see Diagram 2A below as well
as the exploded parts diagrams on p. 5-16).

Measure the flange width of the I-beam. Find the center of the
beam bracket and measure half the width of the flange on either
side of the centerline.
Identify the 4 bolt holes in the beam bracket that lie just outside the
width of the beam flange. Feed A325 structural bolts through those
4 bolt holes of a welded beam clamp as shown at right.
Slide a lock washer onto each bolt, and then secure the bolts with
A325 structural nuts. Do not fully tighten the nuts at this point.
