Study on the Diameter and the Breaking Load of the Wire Rope for Mining

Abstract

Some wire ropes become large in the diameter when load is added, and the other wire ropes that have been used, become bigger in the breaking load than new product. In order to explain these phenomena and establish the new method that load without breaking test, I made this study as the base of it.
At present we use some kinds of diameter in a wire rope
Instead of these I found a new diameter, a clamped diameter, and conceived the method for the measurement of it.
At present we use also some kinds of breaking load as follows.
Therefore, I made clear up these relation and besides these proposed the total minimum sectional area of a wire rope and then obtained the relation between this and a clamped diameter.
