This rig can carry out a variety of drilling techniques which makes it a formidable, yet compact soil investigation rig.
The rig has a powerful impact hammer mounted to the side of the main drill head which can advance windowless sample barrels through soft over burden giving a very high quality of sample. Once harder ground is encountered the rig offers various options. It can continue drilling with hollow or solid stem augers, open hole, odex or even rotary case and core.
The on-board 1 tonne winch allows for in-situ testing to be carried out as required during the drilling process
The MC405 is a bigger rig than the 205 but just as versatile.
This rig is suited to all types of Geotechnical and Environmental ground investigations as well as Geothermal Wells and conventional Water Wells. The machine is capable of operating all rotary drilling systems, D.T.H. hammers, coring and can also carry out window / window-less sampling and in-situ testing including standard U100 sampling.
This rig is a great bit of kit for reaching to those impossible to track to locations. As seen in the pictures we can reach over obstacles such as crash barriers, retaining walls even streams and rivers making the job a lot more cost effective with the capability to still get perfect samples. This rig has all the same working limitations as the 205’s.
