Which crane type is commonly recognized for being driven on highways due to multi-axle configurations?

• A. Rough terrain (RT)
• B. All-terrain (AT)
• C. Crawler (crawler)
• D. Tower (tower) cranes

Answer: (B)

All-terrain cranes are built to be road-mobile. Their multi-axle undercarriage distributes weight so they can meet highway axle-load limits and be driven on roads like a heavy truck. This combination gives them the mobility to travel between job sites on highways, then deploy stabilizers and set up for lifting once on site. The other types are specialized for different conditions: rough-terrain cranes excel off-road on rough ground but aren’t primarily designed for highway travel; crawler cranes move on tracks and aren’t driven on highways; tower cranes are fixed at a site and transported in pieces, not driven between sites.
