Crawler cranes and all-terrain cranes can both handle heavy lifting, but they are built around different operating priorities. The crawler crane is designed around tracked mobility and on-site lifting, while the all-terrain crane combines a road-going carrier with a crane system designed for lifting at the jobsite.
That difference affects transport, setup, ground support, working radius and the types of projects where each crane is most practical.
A crawler crane uses a tracked undercarriage rather than a wheeled carrier. The tracks allow the crane to move around a construction site and provide a large contact area with the ground. Crawler cranes are widely used for major infrastructure, industrial construction and other projects involving substantial or repeated lifts. Liebherr’s current LR crawler range spans machines from 100 tonnes to 3,000 tonnes of maximum rated capacity.
A key advantage is that the crane’s lifting system remains integrated with the tracked carrier. On large crawler cranes, however, transport is a major part of project planning. The crane may need to be transported in components and assembled at the site, depending on its size and configuration.
This makes crawler cranes particularly relevant where lifting work continues from the same project location for an extended period. Their value is not simply the maximum rated capacity. Boom configuration, ballast, working radius and ground conditions determine what the crane can actually lift on a particular job.
An all-terrain crane uses a wheeled, multi-axle carrier designed for road travel as well as operation on construction sites. Tadano’s current India range includes all-terrain cranes from 40 tonnes through 500 tonnes. The range uses multiple axle configurations and all-wheel steering systems, depending on the model.
The road-going design reduces the need to dismantle the complete crane simply to move between jobsites. Actual road movement still depends on the machine’s configuration, axle loads, local regulations and any permits required for the route.
At the worksite, the crane is normally deployed on outriggers for lifting. That makes support conditions and outrigger configuration important parts of the lift plan.
Liebherr’s LTM 1055-3.3 illustrates the category at the lighter end of the range. It has a maximum rated capacity of 55 tonnes, a 40 m telescopic boom, a maximum hoist height of 54 m and a maximum radius of 46 m on a three-axle carrier.
At the other end of Tadano’s current India range, the AC 8.500-1 is rated at 500 tonnes. It has a 56 m main boom, boom extensions from 6 m to 90 m and a maximum tip height of 145.8 m.
| Factor | Crawler Crane | All-Terrain Crane |
|---|---|---|
| Undercarriage | Tracks | Wheeled, multi-axle |
| Primary mobility | Around the jobsite | Between roads and jobsites, then around the worksite |
| Lifting support | Depends on crane design; conventional crawler cranes work from their tracked base | Normally lifted on outriggers |
| Transport | Large machines may require component transport and site assembly | Designed for road travel within applicable configuration and regulations |
| Best suited to | Long-duration heavy lifting and large site-based projects | Projects requiring frequent relocation between lifting locations or jobsites |
| Typical boom system | Often lattice boom on large crawler cranes | Telescopic boom, with optional extensions depending on model |
| Large-capacity examples | Liebherr LR range up to 3,000 t | Tadano India range up to 500 t |
The capacity figures above are manufacturer maximum ratings for their respective product ranges. They should not be treated as directly comparable lifting performance because actual capacity varies with radius, boom length, ballast, configuration and other load-chart conditions.
The largest practical difference appears before the lift begins.
A large conventional crawler crane can be highly mobile once assembled, but transporting the crane to the project can require a logistics plan covering the carrier, boom sections, counterweights and other components. The larger the crane, the more significant that mobilisation requirement becomes.
An all-terrain crane is designed to cover road travel as part of its operating concept. Liebherr’s three-axle LTM 1055-3.3, for example, has a road speed of up to 85 km/h in its specified configuration.
That makes all-terrain cranes useful where the lifting position changes frequently or the contractor needs to move the crane between projects. It does not remove transport planning altogether: axle loads, overall dimensions and road regulations still have to be considered.
Ground support is important for both crane types, but the way loads are transferred to the ground is different.
A crawler crane transfers its load through its tracks and does not use the same outrigger arrangement as a typical all-terrain crane. Track dimensions, total machine weight and configuration all affect ground loading.
An all-terrain crane transfers significant support loads through its outriggers during lifting. Outrigger spread and support conditions therefore form part of the lift planning process. Tadano’s crane-management systems account for different outrigger configurations when determining available lifting capacity.
Neither machine type removes the need for a properly assessed and prepared working surface.
The distinction becomes less straightforward with telescopic crawler cranes.
These machines combine a tracked undercarriage with a telescopic boom. They retain the crawler crane’s ability to manoeuvre on site while using a boom system that can extend and retract without the same assembly requirements associated with a large lattice boom.
Liebherr’s LTR 1060 is rated at 60 tonnes and has a 40 m telescopic boom, a maximum hoist height of 55 m and a maximum radius of 50 m. Liebherr states that it can be transported as a single unit and manoeuvred with a load.
The larger LTR 1220 is rated at 220 tonnes, with a 60 m telescopic boom, a maximum hoist height of 101 m and a maximum radius of 88 m. Liebherr specifies that the crane can travel with a full load on the hook and can erect itself without additional equipment.
These machines should not be treated as simply smaller versions of conventional lattice-boom crawler cranes. Their transport and operating characteristics are different enough to warrant a separate category when comparing crane fleets.
The decision should start with the lift plan rather than the headline capacity.
A crawler crane is often the better fit when the project involves sustained heavy lifting from a defined work area and the crane can remain assembled on site. Large infrastructure, industrial and major construction projects can make use of the crawler crane’s combination of lifting capacity and tracked mobility.
An all-terrain crane is generally more useful when road mobility is important and the lifting work requires the machine to relocate regularly. Its telescopic boom and outrigger-based setup also make it practical for a wide range of construction and industrial lifting work.
A telescopic crawler can sit between those requirements, particularly where a project needs tracked site mobility together with a telescopic boom and the ability to reposition under controlled lifting conditions.
The final choice comes down to the complete operating picture: required load at the working radius, boom configuration, ground support, transport restrictions, setup requirements, project duration and the frequency of crane relocation. Maximum rated capacity is only one part of that decision.
