Cranes are commonly used for lifting heavy steel components on construction sites due to their design, which is specifically tailored for moving large and heavy loads efficiently. They can reach great heights, have a wide range of motion, and can lift substantial weights with stability and precision.
While forklifts do provide lifting capabilities, they are generally more suitable for moving materials over shorter distances and lifting loads that are not as heavy as those handled by cranes. Hoists offer vertical lifting solutions, typically for lighter loads or in confined spaces, yet they lack the versatility and reach of cranes. Pulleys can aid in lifting and can be useful in certain scenarios to gain mechanical advantage, but they are not commonly employed for the large-scale lifting operations typical in steel construction.
Therefore, cranes are preferred for their capability to handle the demands of lifting heavy steel components safely and effectively.
