Rough terrain cranes: built for the job site
A rough terrain crane is the lifting machine made to work off the road, on the dirt and rubble of a live site. How its pick and carry, all wheel steer and outriggers make it the site crane of choice.

Most cranes are built to travel the road and then lift from a prepared spot. A rough terrain crane is built for the opposite: to live on the job site, on the dirt, mud and rubble, and move around it lifting as it goes. It cannot drive on public roads at speed, but on site it does what road going cranes cannot, crossing uneven ground on big tyres, steering all four wheels into tight corners, and even carrying a load as it drives. For confined, unprepared sites it is often the most practical crane there is, which is why it is one of the most hired lifting machines on construction sites.
This guide is grounded in the features that define a rough terrain crane.
A crane that lives on site
A rough terrain crane works off road on a single site, crossing rough ground on oversized tyres, steering all wheels, and able to pick and carry a load within its chart.
Pick and carry
One of its defining abilities is pick and carry: the crane can lift a load and drive with it, within the limits set out in its load charts. That lets it move material around a site without setting down and re rigging at every point, a big time saver on a spread out job, as long as the operator stays inside the charted pick and carry capacities.
Mobility and stability
Rough terrain cranes run all wheel drive on two axles with oversized tyres for grip on uneven ground, and offer two wheel, four wheel and crab steering so they can manoeuvre and crab sideways in tight spaces. For lifting they deploy independent H pattern outriggers that extend to build a stable platform even on uneven ground, so the crane can set up and lift where the surface is far from level.
| Feature | What it gives |
|---|---|
| Pick and carry | Drive with a load within the chart |
| All wheel drive, big tyres | Cross rough, unprepared ground |
| Four wheel and crab steer | Manoeuvre in tight site spaces |
| H pattern outriggers | Stable lifting on uneven ground |

Where it fits
- 1
Confined site work
Tight, unprepared sites suit its mobility.
- 2
Repositioning lifts
Pick and carry moves loads without re rigging.
- 3
Uneven ground
Outriggers and tyres handle rough surfaces.
- 4
Single site duty
It stays on site rather than touring the road.
It is a site crane, not a road crane
A rough terrain crane is slow on the road and needs transport between sites, where an all terrain crane drives itself. Use the rough terrain crane for working a site, not for touring between them.
