2 3. COOKES. New Zealand's Most Extensive Industrial Support Service. The firm of William Cooke & Company was founded in 1862 at Tinsley in the United Kingdom. An office was opened in Auckland in 1911 to handle the distribution of wire rope and associated products in New Zealand. Cookes are now part of the F. K. I. group of Companies that includes a number of the world's leading lifting equipment manufactur- ers including Parsons Chain Co. ( ) and Crosby International ( ). Cookes operate New Zealand's only wire rope manufacturing plant. Cookes operate websling and webbing load restraint manufacturing plants in both Auck- land and Christchurch. Cookes Engineering Workshop manufactures cutting edges for supply throughout New Zealand.

3 4. COOKES. All products manufactured by Cookes meet worldwide standards such as Lloyds Register of Shipping, New Zealand Standards Asso- ciation, British Standards and ISO 9002. Quality Assurance. Cookes head office and branches carry TELARC ISO 9002 accreditation. Cookes operate load testing facilities at most branches throughout New Zealand and on-site testing vehicles in both Auckland and Christchurch. In 1992 a manufacturing plant was installed to produce the Brifen road safety barrier system for highways throughout New Zealand and export. In 1994 a 150 tonne Rotary Swaging Ma- chine was installed to produce swaged wire rope for the logging industry and later the fishing industry. In 2001 a second swager was added to handle the increased demand for this product.

8 8. COOKES. This catalogue is designed to provide a non-techni- cal guide to the selection of a suitable wire rope for various applications. Technical information is re- stricted to weights and breaking loads and a few for- mulae. Constructions and sizes shown here are those commonly available and used in New Zealand but there are many others and enquiries for special ap- plications should be directed to your nearest Cookes branch. wire rope is a machine of many working parts and like most machines it must be made right, selected right for the application and used correctly in that application. Like many machines, there is a great variety of types of wire rope , each with different prop- erties to suit it's intended use.

9 The internal combus- tion engine used to power a racing car is quite differ- ent to the one powering a large truck although they both may produce the same horsepower. Like many machines it is impossible to combine the advantages of each type into one single machine. The high horse- power and low weight of a racing engine would be great in a truck. The high fuel cost and short life would not. The same with wire rope , the attributes that make one construction eminently suitable for one applica- tion could well be a total disaster in another. 9. COOKES. wire rope DESIGN & CONSTRUCTION. wire ropes are composed of independent parts - wires, strands and cores - that interact with each other dur- ing service.

10 wire rope engineers design those parts in different steel grades, finishes and a variety of constructions to attain the best balance of strength, abrasion resis- tance, crush resistance, bending fatigue resistance and corrosion resistance for each application. To select the best wire rope for each application, one must know the required performance characteristics for the job and enough about wire rope design to se- lect the optimum combination of wire rope proper- ties. The following information is provided as a basic guide. Our expert in house staff and field service spe- cialists are available to provide more specific rec- ommendations. 10. COOKES. The three attributes of a wire rope to consider are: (1) Strength.
