Selecting the right CPT rig is about more than pushing capacity. Ground conditions, site accessibility and operational requirements all influence which type of equipment is best suited to a project.

Different working environments require different solutions, from truck-mounted CPT rigs to crawler systems and lightweight stand-alone penetrometers.

Truck-mounted CPT rigs

On paved and easily accessible terrain, a truck-mounted CPT rig is often a practical choice. It offers efficient road transport, quick mobilisation between testing locations and uses its own weight to provide the reaction force required for CPT operations.

CPT crawler rigs

For soft, uneven or difficult-to-access terrain, crawler rigs offer important advantages. Their wide tracks distribute the machine’s weight over a larger surface area, improving traction and helping operators access locations where wheeled vehicles may struggle.

Crawler-truck combinations

Some projects require both road mobility and off-road capability. A crawler-truck combines these advantages, allowing efficient transport over longer distances followed by tracked movement across challenging terrain.

Stand-alone penetrometers

When access is severely restricted or working space is limited, a lightweight stand-alone penetrometer can offer a practical alternative.

These systems can be transported in separate components and assembled near the testing location. Unlike self-ballasted rigs, they rely on suitable ground anchoring to generate the reaction force required for testing.

Finding the right solution

Choosing the right CPT equipment involves evaluating more than the required pushing depth or force. Access routes, slopes, ground bearing capacity, available working space and distances between testing points all play an important role.

Gouda Geo-Equipment offers a range of CPT pushing solutions designed for different site conditions and operational requirements.

Ultimately, the right CPT rig is the one that can reach the required testing locations and perform reliably once it gets there.
