Not every construction or lifting project takes place on perfectly level ground. From sloped driveways and uneven building sites to rugged outdoor terrain, many projects require cranes to operate in challenging environments. The good news is that with the right equipment and proper site preparation, it’s entirely possible to use cranes safely and effectively on uneven or sloped ground. In this blog, we’ll explore how it’s done and which crane types are best suited to the job.
Operating a crane on uneven terrain brings additional safety considerations. Stability is crucial, even a small tilt in the ground can dramatically affect a crane’s lifting capacity and balance. Without the proper setup, this can increase the risk of the crane tipping or the load shifting unexpectedly.
That’s why the type of crane and the way the site is prepared play a vital role in ensuring a safe and efficient lift.
All-terrain cranes are designed for exactly these kinds of conditions. As their name suggests, they can operate both on and off-road, making them ideal for uneven or mixed surfaces.
Key advantages include:
Hydraulic suspension systems that adjust automatically to maintain balance.
Large, durable tyres that provide traction on gravel, dirt, and grass.
Powerful lifting capacity while maintaining mobility between multiple job sites.
These cranes are especially useful in urban areas like London where access might involve crossing rough or partially developed ground before reaching a lifting location.
Another excellent option for uneven terrain is the crawler crane, which uses tracks instead of wheels. This design distributes the crane’s weight more evenly, reducing ground pressure and improving stability on soft or sloped surfaces.
Benefits of crawler cranes:
Tracks provide outstanding grip and balance, even on steep gradients.
No need for outriggers, as stability comes from the large track footprint.
Ideal for long-term projects where the crane needs to move frequently across site.
Crawler cranes are commonly used on large construction sites, bridge projects, or undeveloped land where surfaces can be unpredictable.
Even the most advanced crane requires a stable base. Before any lift begins, site preparation is essential to reduce unevenness and improve stability. This includes:
Ground assessment: Checking for soft spots, loose soil, or water accumulation.
Levelling pads or mats: Outrigger pads or steel plates can spread the crane’s load evenly across the surface.
Access planning: Ensuring the crane can move safely to and from the lift location.
Weather checks: Rain and frost can make slopes more hazardous, so timing is important.
At Complete Lifting Services, our team can advise on the best crane for your site conditions and carry out a thorough assessment before the lift begins.
The correct crane choice depends on multiple factors — the degree of slope, surface material, and weight of the load. For construction or maintenance projects in built-up areas, an all-terrain or mobile crane often provides the ideal combination of flexibility and performance.
If your project involves more challenging surfaces, crawler cranes offer unmatched stability. Either way, using the correct crane ensures your lifting operation is safe, efficient, and compliant with UK safety regulations.
Yes, cranes can absolutely be used on uneven or sloped ground — but only with the right equipment, preparation, and expertise. The combination of skilled planning and the right crane type makes even the toughest sites manageable.
