CPT rams can be mounted on jack-up platforms, crawlers and subsea rovers, to name a few. As well as performing CPTs, all our rigs can install geotechnical instrumentation and take high quality samples.
 
Larger rigs are laid out as mobile offices with faxing and emailing facilities enabling soil investigation results to be sent to Lankelma engineers and clients directly. With the smaller rigs, operators and engineers carry laptops.
 

• Track trucks  -  the tracks are lowered by hydraulic jacks at each corner of the truck, enabling in-situ soil testing on muddy, uneven sites. In truck mode, mobilisation from site to site is fast, with no need for low loaders. UK3, UK15
     
• Crawlers  -  we have crawlers ranging from an 8.5 tonne 'bogskipper', designed for use in peat bogs, to a 20.5 tonne crawler. A large footprint and large ground clearance make our most recent crawler suitable for use in extremely soft terrains. UK2, UK7, UK8.
     
• Excavator mounted CPT rig  -  designed for locations with restricted access. This system attaches to any "Miller Quick hitch" compatible mechanical excavator that can lift the 2.2 tonne weight of the rig to the desired height of the embankment or test location. UK14.
   
• Standard truck  -  We have one standard 6 x 6 truck suited to medium to hard terrains. UK1.
   
• Cantilever frame  -  allows CPT to be perfomed close to quay walls. It has been used to perform wing cone tests to proof lime cement columns, with the frame and CPT rams craned into the pit.
    
• Mobile / basement rams  -  a hand portable system with an operational hieght of 1.75m. UK9.
   
• Rail specific rigs  -  Lankema has developed rigs to work within the restrictions of the rail environment: the rail truck (trackbed) UK12; excavator mounted rams (embankments and cuttings) UK14; lightweight rams (tunnel walls) UK10.  
        
• Overwater rams  -  a stand-alone 20 tonne hydraulic ram set, modified to enable installation onto a pontoon or self-elevating jack-up platform.

  
CPT rig for the Antarctic  
   
Lankelma designed and constructed in-house, a CPT rig for the Antarctic.  We sponsored and collaborated with Adrian McCallum, a former Major in the Australian Army, and now a PhD student at the Scott Polar Research Institute (SPRI), to investigate the strength of polar snow.  read the bulletins from Adrian >>
