It also applies to other overhead material handlingmachinery and equipment that support and transport loads within thedesign rating, vertically or horizontally, during normaloperations. It also applies, when agreed upon between the buyer andmanufacturer, to loading caused by abnormal operations orenvironmental events, such as seismics. Secondary welds that willbe subjected to stresses of less than 6000 psi (41.4 MPa)’ needonly meet the requirements of Section 5, Workmanship, and Section8, Weld Quality and Inspection. The engineering drawings shallspecify the joint detail, type, and size of weld. Thisspecification is not intended for application to construction- orcrawler-type cranes.
