Quick Summary

Figure 2: Traveling jib crane

A traveling jib crane is a type of machine designed to lift and move heavy objects both vertically and horizontally. It is distinct from devices solely for vertical lifting or conveyors for bulk materials.1

Key features include:
* Jib: A strong, unbending beam that supports the lifting mechanism.1
* Trolley: A wheeled carriage that moves along the length of the jib, from which the pulley system is suspended.1

These cranes typically have lifting capacities ranging from 5 to 250 tons. Stability is a critical concern, especially when lifting heavy loads at a distance, often requiring ballast weights to prevent tipping.1
