Which combination lists three common crane types used on construction sites?

• A. Floating crane, underwater crane, micro crane
• B. Mobile crane, tower crane, crawler crane
• C. Hand crane, roller crane, portable crane
• D. Overhead gantry crane, pile driver, scaffold crane

Answer: (B)

On construction sites, the lifting toolkit usually centers on three versatile crane families that cover a wide range of tasks and ground conditions: mobile cranes, tower cranes, and crawler cranes. A mobile crane is built to move quickly around the site and perform lifts with flexibility in reach and load, which makes it handy for varied, on-the-spot tasks. A tower crane, tall and fixed to the structure or setup area, provides the long vertical reach and large working radius needed to place materials at great heights on tall builds. A crawler crane travels on tracks, delivering very high lifting capacity with strong stability, especially on uneven or loose ground where wheels might struggle. Together, these three types let crews handle quick, mobile lifting, high-rise placement, and heavy-duty lifts across different site conditions.

The other options mix in crane types that aren’t typically grouped together for standard construction site use or involve equipment that serves more specialized roles (like marine work, small manual lifting, or workshop-based systems). That’s why the combination of mobile, tower, and crawler cranes best fits the common needs on construction sites.
