Step 5: Fasten the I-beam to the uprights.
a) [NOTE: The bolts and nuts referred to as a single part no. (11134585) in bills of materials on p. 5-16].Insert two 1/2”
structural bolts through the holes of a beam clamp and through two holes in the beam mounting plate you identified
in step 4d. Use two lock washers and nuts to hold the beam clamp in place. Do not fully tighten the nuts at this
point.
b) Position the I-beam on the beam mounting plate with one flange in the gap between the beam clamp and the
mounting plate.
c) Install a second beam clamp and fastening hardware on the other flange of the beam.
d) Repeat steps 5a-5c with the other upright.
Step 6: Make sure that the I-beam is centered on both beam plates and that the beam clamps significantly overlap the
flange on both sides. Tighten all nuts to 50 - 52 ft·lb of torque .
Step 7: Stand the crane on its feet.
a) DO NOT attempt to stand the crane unless all other people are a safe distance away. Sudden, unexpected
movement is possible as the crane passes its natural tipping point.
b) Is using an overhead hoist, attach the hoist chain to the center of the I-beam. Slowly raise the beam until the crane
rotates to stand on its feet.
c) If using a fork truck, approach the crane from the I-beam side. Slide the forks under the center of the I-beam. Slowly
raise the beam while driving forward until the crane stands on its feet. WARNING: DO NOT raise the beam unless
all other persons are a safe distance away from and behind the fork truck.
