The Difference Between Rough-Terrain Cranes and All-Terrain Cranes

When it comes to renting a crane for your next project, you want to be sure you’re picking the right crane for the job. While the difference between a crawler crane and a tower crane is fairly clear-cut, it can be harder to discern the right option when you’re deciding between more similar models of cranes.

Rough-terrain and all-terrain cranes, two types of cranes commonly used in construction, are very similar in their capabilities and functions, but there are a few key differences between them that can help you determine which is best for your project.

 

Rough Terrain Crane Features

Rough-terrain cranes, also called off-road cranes, are mounted on a four-wheeled undercarriage. Both the wheels and the base are wider to boost the crane’s stability, and the wheels are taller to increase ground clearance over rugged terrain.

Rough-terrain cranes come with a telescoping boom and outriggers to stabilize and support during lifts. They are lighter than all-terrain cranes due to two factors: rough-terrain cranes are operated and driven from the same, small cab, and they only have one engine which powers both the boom and the undercarriage.

Their four-wheel drive and power steering allow for easy maneuverability over the uneven ground of construction sites with unpacked soil, even within tighter spaces. However, rough-terrain cranes are unable to travel at speed on public roads, meaning they need to be transported to job sites.

 

All-Terrain Crane Features

All-terrain cranes come equipped with a longer boom, more tires—usually between six and ten—and two engines. That, combined with their wider cab, makes them much heavier than rough-terrain cranes, though they may still need the assistance of outriggers during lifts.

Like the rough-terrain crane, all-terrains are highly maneuverable over uneven ground, but they also provide the added benefit of being able to maintain higher speeds on public roads. In the crane industry, all-terrain cranes are often viewed as the ideal combination of a truck-mounted crane and a rough-terrain crane, as they offer mobility and transportability without sacrificing the ability to handle off-road conditions.

 

Choosing Between All-Terrain and Rough-Terrain

So, summed up simply:

  • All-terrain cranes can travel public roads, while rough-terrain cranes need to be transported
  • All-terrain cranes can typically reach higher heights
  • Rough-terrain cranes are lighter, so they have a more limited lifting ability when compared to all-terrains
  • Rough-terrain cranes can get by with less site preparation due to their off-road-focused design

Both types of cranes possess excellent maneuverability, even in snow, mud, and other challenging conditions. When making the choice between an all-terrain or rough-terrain crane, keep these factors in mind:

  • Load weight
  • Necessary boom height
  • Terrain difficulty
  • The cost of transporting a rough-terrain crane
