## What size IPS wire rope would you specify if the rope is to be of regular lay construction?

1. It is desired to select a wire rope for use in an automotive tow truck application. A single line is to be used and, considering dynamic loading involved in pulling cars back onto the roadway, the typical load on the rope is estimated to be 7000 lb. It is estimated that approximately 20 cars per day will be pulled back onto the highway (i.e., the rope experiences 20 “bends” per day) under full load. If the truck is used 360 days per year, and a design life of 7 years is desired for the rope:

a. What size IPS wire rope would you specify if the rope is to be of regular lay construction?

b. What minimum sheave diameter would you recommend?
