Designed for use on excavators ranging in size from 15 to 25 tons (13.6 to 22.6 t), the Montabert CPA 225E drilling attachment enables operators to transition from digging to drilling in a matter of minutes. The CPA 225E drilling attachment is easily transported between job sites, delivering optimal drilling power in the blast hole, slide stabilization, tunneling, anchor bolting and other long-reach applications.
The 3,197-lb. (1,450 kg) CPA 225E drills holes measuring 1-1/2 to 3 in. (3.8 to 7.6 cm) in diameter and up to 14 ft. (4.3 m) deep. The addition of an optional 12-ft. (3.6 m) rod adder enables the CPA 225ER to reach a drill depth of 26 ft. (7.9 m).
Standard features on the single-pass CPA 225E drilling attachment include an aluminum feed — providing 47 degrees of drill rotation — as well as a high performance Montabert HC50 drifter. The HC50 is equipped with a proactive hydraulic dampener and an energy recovery system to ensure a long life span for the striking bar and provide high efficiency drilling performance. In addition to ensuring straight hole drilling, the HC50 drifter delivers progressive blows while absorbing and recovering reflected energy — safeguarding various components of the drilling attachment from damage.
The Intelsense system is essential to the CPA 225E drilling attachment’s overall performance. This radio-controlled performance-managing feature automatically analyzes drilling conditions and adjusts factors such as feed pressure, feed speed, anti-jamming controls and percussion pressure.
