Rough Terrain Crane
The main advantage:
Rough terrain cranes capable of maneuvering over surfaces and around obstacles that limit the movement of rubber-tire truck cranes and track hoe cranes. They also have over-sized tires which are significantly wider and larger in diameter than those found on a typical radial-tire truck crane.
The ability to maneuver over uneven ground, up and down steep grades, over muddy and snowy terrain, and over obstacles. In addition to the tires, they have a wider wheel base and larger engines than truck cranes.
A rough terrain crane can level itself even when the ground beneath the machine is sloped or uneven. The narrow body of a standard crane means the center of gravity is elevated which equates to instability. As most track cranes do not have outriggers, the stability of a rough terrain crane makes it far more useful on a rugged jobsite.
The main disadvantage:
- Though not as complicated as crawler crane, transportation between site is still not an easy task
- Need an outrigger to stabilize when lifting load
- Limited height and load capacity
Designed specifically for pick-and-carry operations, the rough terrain crane is used for building bridges, operations in power and chemical plants and refineries and for large-scale construction projects.
