panels are welded to the angle in the footer before concrete placement. Because of this operation, all aspects of footer construction must be completely checked for alignment and squareness. Once concrete is placed, there is no way to correct errors.
As mentioned above, forms are provided for the foundation. Using table 9-4 as a guide, figure 10-13 gives you a simple foundation layout by parts designation. As noted in figure 9-13, the cross pipes are not provided in the kit. They must be ordered when the project is being planned and estimated.
With the placement of the machinery and forming of the building panels in progress, your next considera- tions are the placement and the weight-lifiing capabil- ities of the crane. Check the weight-lifiing chart of the crane for its maximum weight capacity. This dictates the number of panels (recommend 5/ABM 120 and 3/ABM 240) you can safely lift at the operating distance. As with all crane operations, attempting to lift more than the rated capacity can cause the crane to turn over.
Attaching the spreader bar (fig. 9-14) to the curved formed panels is a critical step; failure to clamp the
