Name a common type of crane used in ironworking.

The choice of a tower crane as a common type of crane used in ironworking is well-founded. Tower cranes are specifically designed for lifting heavy loads to significant heights, making them ideal for the construction of tall buildings and structures where ironworkers are commonly engaged. Their design allows for both vertical and horizontal lifting, offering impressive range and stability, which are crucial when handling steel beams and other heavy materials.

In contrast, while mobile cranes and gantry cranes are also utilized in construction settings, they serve different functions and are often used in different scenarios. A mobile crane is more portable and versatile, able to move around job sites, but is generally not used for the same high vertical lift situations associated with tower cranes. Gantry cranes, while useful in specific applications, are typically employed in places like warehouses and factories rather than on high-rise construction projects. Forklifts, on the other hand, are primarily for lifting and transporting materials over short distances rather than for heavy lifting at heights, thus not suited for the types of tasks that tower cranes excel in.
