Lankelma’s new Minicrawler Cone Penetration Test (CPT) rig proved its use by being put directly to use on a residential project in London
Lankelma projects engineer Chris Dimelow pointed out the 758mm wide rig can tackle sites with “challenging access” as it can pass through a standard doorway and can gain access through garden gates and garages during domestic contracts.
The rig is small enough to be transported by a small commercial vehicle and has a very quiet engine making it ideal for noise-sensitive sites such as residential London.
“The rams can also be removed from the tracks,” Dimelow added. “Using concrete anchor bolts, we can then carry out tests in areas of a site with even tighter access, without having to mobilise additional equipment. The rig can use our full range of cones and samplers and can also install instrumentation, such as piezometers.”
The 1t rig is also useful for projects on rivers, canals, flood and sea defences, and embankments, where access is often difficult for conventional rigs.
