Overview of Crawler Cranes
Crawler cranes are tracked cranes commonly used for high-capacity and complex lifting operations across construction and infrastructure projects.
Features
Crawler cranes have a tracked undercarriage and are available in configurations such as lattice boom systems for major lifting operations. Depending on the crane and configuration, they can remain assembled on site and may be able to travel within the working area under defined operating limits.
Benefits
These cranes can support longer or more complex lifting programmes by reducing repeated mobilisation and allowing the crane configuration to be planned around the required load, working radius and site conditions. Where operating limits permit, the ability to relocate while assembled can also support lifts across multiple locations on the same site. This can provide greater continuity throughout longer lifting programmes.
Use Cases
Crawler cranes support major lifting operations across construction, infrastructure, power generation and industrial projects. They are particularly well suited to wind turbine construction, infrastructure and heavy structural lifting operations where crawler crane capacity and site mobility suit the project.
Overview of Mobile Cranes
Wheeled mobile cranes combine lifting capability with road and site mobility, with crane configuration varying according to the required operation.
Features
Mobile cranes are mounted on wheels and typically use telescopic boom systems that extend and retract to provide different working lengths. Many models are designed for road travel, although transport requirements depend on the crane and configuration.
Benefits
Road mobility can make mobile cranes well suited to projects involving multiple sites or frequent relocation between lifting locations. Compared with large lattice crawler cranes, they may also require less on-site assembly, which can help reduce mobilisation time where the crane and lifting requirements allow. Their comparatively straightforward relocation can also support shorter-duration works or programmes where the crane needs to move between sites efficiently.
Use Cases
Mobile cranes are commonly used across construction, infrastructure, structural installation and specialist lifting projects where access and mobility are important.
Comparing Crawler Cranes and Mobile Cranes
Both crawler and mobile crane fleets include high-capacity configurations, but their mobility, setup requirements and operating characteristics differ.
| Feature | Crawler Crane | Mobile Crane |
|---|---|---|
| Lifting capacity | High-capacity options: Ainscough capability 300T–700T | High-capacity options: Ainscough capability up to 800T |
| Stability | Tracked undercarriage; suitable ground remains critical | Typically uses outriggers during lifting; suitable ground remains critical |
| Site mobility | Can relocate while assembled where the crane, route and operating limits permit | Good manoeuvrability, depending on crane and site |
| Inter-site mobility | Typically requires dedicated transport and mobilisation planning | Many models are designed for road travel |
| Setup time | Can require substantial on-site assembly | Often requires less assembly than large lattice crawlers |
| Site footprint | Working space depends on crane dimensions, support arrangement, counterweight, boom configuration and assembly requirements. | |
| Cost-effectiveness | Depends on mobilisation, configuration, duration and utilisation. | |
Lifting Capacity
Both crawler and heavy mobile cranes are available in high-capacity configurations. The most suitable crane depends on the required load, working radius, configuration and site conditions.
Stability
Crawler tracks distribute crane loads across a broad contact area, while mobile cranes typically use outriggers during lifting. In both cases, the supporting ground must be suitable for the loads imposed by the crane.
Mobility
Wheeled mobile cranes generally offer greater road and inter-site mobility, which can be useful where equipment must move frequently between lifting locations. Crawler cranes instead provide tracked site mobility where the assessed route, configuration and operating limits permit.
Relocation
Wheeled mobile cranes can often be relocated between projects with less dismantling and specialist transport than large lattice crawler cranes. This can be useful for short-duration work or contractors operating across multiple sites.
Setup Time and Preparation
Mobile cranes can require less on-site assembly than large lattice crawler cranes, although setup and ground-support requirements remain specific to the crane and lifting operation. Large crawler configurations may require more extensive assembly and mobilisation planning.
Required Space
Required working space depends on the crane dimensions, support arrangement, counterweight movement, boom configuration and assembly requirements. Some mobile crane configurations can offer an advantage where available working space is restricted, but suitability depends on the crane dimensions, outrigger arrangement and required lifting radius.
Cost Effectiveness
Project economics depend on factors including crane configuration, transport, mobilisation, lift sequencing, duration and utilisation. These should be assessed against the complete lifting programme rather than the crane type alone.
Considerations When Choosing Between a Crawler Crane and Mobile Crane
When comparing crawler cranes and mobile cranes, key project considerations include:
- The size and weight of the loads being lifted
- Ground conditions and site accessibility
- Available operating space
- Project duration
- Frequency of crane relocation
- Required lifting height and reach
- Site restrictions and working environment
- Budget and project costs
When to Choose a Crawler Crane
Crawler cranes can be suitable where high lifting capacity, tracked site mobility and longer-duration operation align with the project requirements. They can also be useful where the crane needs to remain assembled for an extended lifting programme or operate across multiple positions within the same site, subject to suitable access, ground conditions and operating limits.
When to Choose a Mobile Crane
A wheeled mobile crane may be suitable where road mobility, comparatively straightforward mobilisation or rapid deployment are important project requirements. They can also be useful for shorter-duration work, projects involving frequent relocation between sites or operations where available access and working space favour a wheeled mobile configuration.
