Which crane type tends to have the highest front-end capacities?

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

Answer: (A)

The key idea is how stability at a short radius affects how much weight can be safely lifted in front of the crane. Rough terrain cranes are built with a wide, stable four-outrigger setup and a compact frame, which distribute the weight effectively and maximize stability when the boom is near the front. That makes their load charts at small radii higher than other crane types, so they can lift more load straight out in front before stability limits are reached. Tower cranes, crawler cranes, and all-terrain cranes are optimized for different conditions (height and reach, ground stability or travel across uneven ground), which typically means their front-end capacity at short radius isn’t as high as that of rough terrain units. Of course, actual capacity depends on the specific model and configuration, but in general rough terrain cranes tend to provide the greatest front-end lifting capacity.
