Casagrande C6 (Data)
The Casagrande C6 is probably one of the best known rigs worldwide for its versatility under various configurations, our rig has a multi function head allowing it to achieve all the things a compact rotary would but too much greater depths and with its fully articulated mast it can drill at any inclined angle required,
Safety:
As with all of Tor Drillings rigs the unit has a full interlocking safety guard system, kill switches and Chalwyn valve and spark arrestors fitted as standard for safe working on sensitive sites.
Achievable Depth’s
Drilling depth’s for this machine vary depending on Geology, Bore diameter and the Method in use but it is generally used for boreholes up to 150m in most ground conditions but can be used to core or open hole rock to greater depth’s.
The rig stats for access:
Weight = 14.5 tons   /   Width = 3.0m    /   Access Height Mast Down 2.3m    /   Full Height = 7.0m
Drilling Methods Available to the C6
Surface Concrete Removal
A simple compression sprung coring attachment can be used on the rig to cut a 300mm Ø hole through surface concrete, these units were designed and built by Tor we can also attach power breakers which run off of an auxiliary supply available on the machine.

Percussive / Window Sampling:
Percussive sampling can be achieved with the use of the Krupp hammer which allows the rig to drive in linered window sample barrels to recover undisturbed environmental or geotechnical samples; it can also be used to recover U100 samples

Auger Drilling:
Solid stem and Hollow stem augers (sometimes called cased auger) can be used on this machine up to 300mm Ø

Rotary Coring
Rotary coring of hard rock formations can be achieved with this rig with a selection of barrels with varying core sizes

Wire Line Coring
Some of our rigs are set up with fast winch systems to enable wire line drilling in Geo Bore S

Drilling & Casing
Various size odex or symetrix duel drill & case systems can be used on this rig up to a maximum 300mm diameter, these systems are used widely to case of all types of unstable overburden to enable access to lower more competent strata formations whether for environmental or geotechnical site work

In situ Testing
The unit can achieve in-situ SPT’s / CPT’s and undisturbed samples making use of it onboard winch to operate hammers and sampling equipment

Installations
Once drilling is complete in a size and method agreed the created bore can simply be backfilled or installed with a vast array of ground monitoring instruments as required.

Flush Media
Air, Air mist or Water but Mud’s and Polymer flushes can also be used to suit your requirements
