Cranes are built to lift incredibly heavy loads, yet the part doing the actual lifting is often a flexible steel cable. Why use a cable instead of a solid steel rod that seems stronger and more rigid? In this video, we explore why wire ropes are ideal for cranes, how their twisted steel construction handles enormous tension, and how cables work with drums and pulley systems to lift heavy loads. We’ll also look at why a solid rod would be impractical, heavy, and difficult to move—and why crane cables need regular inspection and maintenance.
