Cranes are primarily used to lift and place what?

Cranes are primarily designed for lifting and placing materials, making them essential in construction and industrial applications where heavy items need to be moved. While cranes can be involved in lifting tools when they are securely attached to the load, their main function is not to directly handle tools. Furthermore, cranes are not intended for lifting persons, as this typically requires specialized equipment designed for safety, such as personnel lifts or scaffolding.

Therefore, the statement indicating that cranes are used primarily to lift and place materials and tools is accurate. This underscores the fundamental purpose of cranes in transporting heavy loads safely and efficiently, reinforcing the correct identification of the intended functions of this equipment. The choice that acknowledges the role of cranes in lifting materials while also considering tools aligns with their operational use in the field.
