WIRE ROPE. i ... has grave responsibilities <= Wire rope must be a quality product; for in practically every wire rope installation, human life, property and money are in constant jeopardy. It is to guard against such damages that Wickwire Spencer Wire Rope Engineers are stern dictators of the methods and materials employed in rope manufacture. It is to insure the confidence of the user that they make exhaustive chemical, physical and micro-photographic tests of every wire that goes into every Wickwire Spencer Wire Rope. Samples of finished rope are taken at regular and frequent intervals, and torn asunder in gi- gantic testing machines, to prove the strength and quality beyond a shadow of a doubt. This fidelity in manufacture and testing produces wire rope that not only equals but exceeds the requirements of usual standards, and adds a durability that makes Wickwire Spencer Wire Rope an economical rope to use.
