The Apafor® 230 is a small, yet extremely versatile drilling rig that offers high performance far beyond similar models. It is the perfect drilling rig for geotechnical investigations at a depth of about 30 metres, and even more depending on diameter. It can carry out all types of drilling methods: rotary injection, off-hole rotary percussion, augering, coring, down-the-hole hammering and even dynamic penetrometric testing and compaction control.
Its compact dimensions and hydraulic variable track allow it to pass through narrow doorways and work in difficult-to-reach and confined areas.
Its various removable and interchangeable drilling heads give it multiple functionalities. It can also be equipped with an automatic ramming system for penetrometric tests or rammed cores, an injection pump, a rod brake, a handling winch and data acquisition systems.
The change of working configuration (drilling / ramming) is easily carried out in less than 2 minutes and the working axis of the machine remains the same whatever the configuration:

  • Drilling configuration: the rotation head is positioned in the working axis and system by hammering is removed and stored by simply swivelling it. 

  • Hammering configuration: the detachable rotation head is unlocked and removed from the work spindle, the system by hammering is inserted and locked directly onto the same travel carriage.

For the European market, the Apafor® 230 is offered in a UFCMF version equipped with a safety cage with a physical or immaterial door and a 23 HP YANMAR DIESEL engine that complies with the new European standards in force. For special environments (high heat, humidity, dust, etc.), a tropicalised motor is installed.
