What is one benefit of using cranes in construction?

• A. They are inexpensive
• B. They can lift loads to significant heights
• C. They do not require maintenance
• D. They operate without a power source

Answer: (B)

Using cranes in construction offers several advantages, one of which is their capability to lift loads to significant heights. This is crucial in construction environments where materials, such as steel beams, concrete blocks, or heavy machinery, need to be positioned several floors up or across long distances. The design of cranes allows them to efficiently handle these heavy loads, which manual labor or other equipment may not be able to manage safely or effectively.

The ability to reach such heights not only increases operational efficiency but also opens up possibilities for building design, enabling structures to rise higher and often facilitating the construction process by allowing for broader work areas. This height capacity is a key reason why cranes are indispensable in modern construction projects.
