The EXPLO 350 is a dismountable and portable drilling rig, dedicated to shallow geotechnical and
environmental investigation. It can use various drilling techniques, rotary drilling, coring, augers, SPT or percussion with down-the-hole or top-hole hammer. It is equipped with a diesel 36 HP engine.
The EXPLO 350 rig is made of seven separate and dismountable parts, which can be handled
separately. Their aluminum skids make them easy to transport on any site, even with a very difficult
access. Only 10 minutes are necessary to remount it on site. Its total weight is 930 kg. Using Standard Core drilling techniques with PO sized products the EXPLO350 can reach depths of at least 40m.  

DTH Drilling can be conducted by using a seperate Air Compressor for flushing air and operation of the hammer itself. Depths of approximately 50m can be achieved depending on the DTH Bit, Hammer and Drill Rod diameter.

SPT Testing can be conducted by purchasing the capstan with the hydraulic motor. Pulleys are then mounted at the top of the mast (see attached pictures).
