The Origins of Crane Development
In 10 BC, the ancient Roman architect Vitruvius described a crane in his architectural treatise. This machine featured a mast topped with a pulley; the mast’s position was secured by cables, and these cables, passing through the pulley, were hauled by a winch to lift heavy loads. For particularly heavy loads, two masts could be arranged in a braced, A-shaped configuration to enable lateral movement of the load, though the range of motion was very limited and operation was highly challenging.

The main features of crane tires are that the operator’s cab and the crane’s control cabin are integrated into a single unit, and that the machine evolved from a crawler crane. The crawler tracks and undercarriage of the traveling mechanism have been replaced with a tire-equipped chassis, thereby eliminating the drawback of crawler cranes—namely, that their track pads can damage road surfaces. This type of equipment falls under the category of material-handling machinery.
