504gg2GEORIG 504 is a multipurpose drilling rig powered by a 36 kW diesel engine or a 50 kW diesel engine Tier 4 & Stage 3b.


The rig can be equipped for most geotechnical investigation methods such as soil rock drilling, swedish weight sounding, dynamic sounding/SPT, CPT and more.


GEORIG 504 is equipped with three standard sensors, feed force, rotation and depth. Our innovative design nearly eliminates the friction between the yoke and mast giving a high accuracy and resolution in the feed force parameter which is used in rotary/percussion sounding.






 Dynamic sounding

With two rotary units on the same yoke the operator will have a more ergonomic, userfriendly and efficient working environment. Switching from one rotary unit to the other takes only seconds.








Dynamic sounding/SPT is fully automatic and all parameters are logged in the software. Continuous sounding, use 1 or 2 meter rods and it will be fully pushed down without any interaction by the operator. 



Optional sensors are torque, rotation pressure, hammer pressure, flushing media pressure and flushing media flow.
