figure shows the primary components of the trailer as well as general operations. The key element is the operator’s station at the rear of the trailer (shown in fig. 9-30). The individual selected for this station must be able to understand the machine operations and manuals. From here, the operator controls all the elements required to form the panels. The operator must remain at the controls at all times. The forming of the panels is a complex operation that becomes easier with a thorough understanding of the manuals. From the placement of the trailer on site, to the completion of the curved panel, attention to detail is paramount. As you operate the panel, you will be adjusting the various machine-operating components. Make adjustments for thickness, radius, and the curving machine according to the manuals. Do not permit short cuts in adjustments. Any deviations in adjustments, or disregard for the instructions found in the operating manuals, will leave you with a pile of useless material and an inconsistent building. MACHINERY PLACEMENT To avoid setup problems, preplanning of the site layout is important. Uneven or sloped ground is not a concern as long as the bed of the trailer aligns with the general lay of the existing surface conditions. Using figure 9-31 as a guide, consider the following items when placing the machinery: Maneuvering room for the towing of the trailer, or leave it attached to vehicle (as shown at A); Length of unit is 27 feet 8 inches long by 7 feet 4 inches wide (B); Allow enough room for run-out stands to hold straight panels. Stands have a net length of 9 feet 6 inches each (C); Find point X: From center of curve, measure distance equal to radius in line with front of curved frame. From point X, scribe an arc equal to radius. This arc will define path of curved panel. Add 10 feet for run-out stands and legs (D); Storage area required to store coil stock and access for equipment to load onto machine (E); Direction curved panels must be carried after being formed (F); Level area required to lay panels on ground for seaming. Building will not be consistent if pan- els are not straight when seaming (G); and Space required for crane operations (H). Figure 9-30.-Rear of K-span trailer. 9-18
