Step 4: Fasten the I-beam to the uprights.
a. As shown in Diagram 4A, insert
1
/
2
in. structural bolts through the bolt holes of a beam clamp and through the
selected bolt holes in the beam bracket. Then, slide a lock washer onto each bolt and secure the bolts with
1
/
2
in. structural nuts. Do not fully tighten the nuts at this point.
b. As shown in Diagram 4C, insert the flange of the I-beam into the gap between the beam clamp and the beam
bracket; then install another beam clamp on the other side of the beam to secure the flange on both sides.
Diagram 4B shows
Step 5: 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 the nuts to 50 - 52 ft·lb of torque.
Step 6: Stand the crane on its feet.
Rotate the crane onto its feet in a controlled manner. [For instance, attach a hoist chain to the I-beam and then
slowly raise the beam until the crane rotates to stand on its feet. Alternatively, raise the crane with a fork truck.
Position the forks under the beam and slowly raise it until the crane rotates onto its feet.]
