This technical report covers series, shunt and compound wound motors of two standard enclosure types: TENV (totally enclosed non-ventilated) and TEFV (totally enclosed forced ventilation from a separate source).

This technical report covers new laminated ladle hooks, which are rectangular in cross-section and are used primarily for lifting hot metal ladles. Hooks rigidly attached to a spreader beam are not discussed in this report.

Hot metal cars (a.k.a. torpedo cars, sub cars, bottle cars, Pugh cars, mixer cars) are used to transport molten iron from the blast furnace to the steelmaking facility. They are vital to the everyday operation of integrated steel manufacturers. The purpose of this document is to provide guidelines for inspection, maintenance and repairs of hot metal cars.

Originally prepared as a classroom training course conducted in a number of United States Steel Corporation plants, this manual grew out of a long-felt need in the area of maintenance of overhead cranes powered by DC motors. Two large prints are provided, as well as an answer key for effective study of the principles involved.

This technical report is intended to present guidelines for the repair of steel pressure-containing components that operate above 15 psig in blast furnace installations. Repair design criteria, as well as examples of repair designs that have been successfully applied in practice, are included. This edition clarifies the differences between and requirements of temporary and permanent repairs.

Designed to impart experience-based techniques and repair criteria for cranes, runways and associated components to newer entrants to the crane community, the AIST Overhead Crane Maintenance, Inspection & Repair Handbook contains best practices to improve your crane safety and reliability while minimizing downtime and expense.

This report guides the owner and designer through the many assumptions and parameters involved in the design of a mill building. It suggests loads and load combinations for the design of crane runways, roof structures, floors, columns, building frames and foundations. Information is given for investigation, earthwork and excavation requirements as in the 1997 edition, as well as revisions to vibration, foundation, soil bearing foundation, crane rails and crane rail splices. In the 2003 edition, all information has been reviewed and updated to the current state-of-the-art procedures for design. However, latitude has been provided for even more advanced proven techniques. All information and direction is within the requirements of national codes and specifications. A listing of many references (also revised) is provided.

Designed to impart experience-based techniques and repair criteria for cranes, runways and associated components to newer entrants to the crane community, the AIST Overhead Crane Maintenance, Inspection & Repair Handbook contains best practices to improve your crane safety and reliability while minimizing downtime and expense.
