The Remarkable Kinkora Prestretcher
Publication: John A. Roebling: A Bicentennial Celebration of His Birth 1806-2006
Abstract
One of the most important and least heralded new methods for the construction of steel wire catenary suspension bridge cables was devised by John A. Roebling's Sons' Company of Trenton NJ in the 1920s. The concept of "preliminary straining" has been cited as one of the twenty most significant advances in suspension bridges up to that time. An enormous machine created for the purpose was installed at the company's Kinkora NJ steel mill, setting the stage for the firm's later role as a technological leader in prestressed steel tension members. This paper illuminates the basic concept of the Kinkora Prestretcher, summarizes its history, and describes its present condition.
