What feature describes a crane that can climb transportation routes on wheels and has multiple axles for highway travel?

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

Answer: (B)

All-terrain cranes are built to move between job sites on roads and also work on rough ground. The key feature described—traveling on wheels along highway routes with a multi-axle carrier for highway stability and load distribution—fits this type perfectly. They combine roadability with off-road capability, using a multi-axle tire system so they can drive on public roads to relocate quickly, then deploy stabilizing outriggers for lifting on site. This mobility sets them apart from other cranes: rough-terrain cranes ride on tires and are designed mainly for on-site, off-road work and aren’t as highway-friendly; crawler cranes run on tracks and aren’t suited for highway travel; tower cranes are fixed at a site and aren’t mobile between locations. So the ability to climb transportation routes on wheels and manage highway travel with multiple axles is a hallmark of all-terrain cranes.
