Armco's New Wire Rope

Offers Rotation Resistance —Literature Available

Armco's Union Wire Rope has announced a new wire rope that offers, for the first time, rotation resistance without sacrificing strength or crushing resistance.

The new product overcomes the deficiencies that have been in- herent in other rotation-resist- ant ropes.

It is engineered for use on overhead cranes with a single hoisting line and in other appli- cations that require minimal block spinning while retaining a high load capacity level. Union

Wire Rope's new product is a 10 by 19 rope, consisting of 10 outer strands wrapped around a spe- cially designed core. Each strand is of a 19 Seale construction. A patent is pending on the design.

Rotation resistance, or low torque characteristics, is possible because the 10 by 19 rope's outer strands are laid in an opposite direction to that of the core. The rope's special core is said to pro- vide more steel area than the ones used in other rotation-resist- ant rope designs. It offers better resistance to drum crushing, and

New Instrument Permits

NDT Of Fiberglass Hulls —Literature Available

A new ultrasonic gage that measures the thickness of fiber- glass walls usually to within 0.01 inch has been developed by Kraut- kramer-Branson, Inc., Stratford,

Conn.

The instrument, known as Mod- el 202F, permits the nondestruc- tive thickness measurement of fiberglass products such as boat hulls, pipes, storage tanks, and pressure vessels. The instrument makes its measurements froip only one surface of the materials.

Because the instrument works by bouncing sound waves off sur- faces or discontinuities in the ma- terial, it instantly reveals flaws such as delaminations and air bubbles. The 15-ounce instrument gives precise readings on most fiberglass compositions at thick- nesses up to three and one-half inches.
