Ko­matsu Aus­tralia has launched the PC210LCi-10 ex­ca­va­tor, the com­pany’s first ex­ca­va­tor with fully in­te­grated In­tel­li­gent Ma­chine Con­trol (iMC).

The PC210LCi-10 has an op­er­at­ing weight of just over 23 tonnes and is pow­ered by a 123kW Ko­matsu SAA6D107E-2 diesel en­gine con­fig­ured to US Tier 4 In­terim emis­sions stan­dards.

Ko­matsu’s iMC con­cept is de­signed to let op­er­a­tors fo­cus on mov­ing ma­te­rial ef­fi­ciently, with­out hav­ing to worry about dig­ging too deep or dam­ag­ing the tar­get sur­face.

The com­pany says the sys­tem can de­liver a more than 60 per­cent im­prove­ment in work ef­fi­ciency when com­pared with con­ven­tional con­struc­tion pro­cesses.

Ko­matsu says its iMC sys­tem dif­fers from tra­di­tional ma­chine guid­ance sys­tems which still re­quire man­ual in­put and op­er­a­tor skill.

“Ko­matsu’s iMC ex­ca­va­tor en­ables op­er­a­tors to achieve op­ti­mum speed to fi­nal grade ac­cu­racy with min­i­mal op­er­a­tor in­puts, while elim­i­nat­ing the need for man­ual grade check­ing,” Ko­matsu Aus­tralia na­tional tech­nol­ogy so­lu­tion man­ager Aaron Marsh says.

The sys­tem uses an ar­ray of in­te­grated sen­sors placed across the ma­chine. Stroke-sens­ing hy­draulic cylin­ders on the boom, arm and bucket pro­vide real-time po­si­tion­ing data, track­ing the lo­ca­tion of the cut­ting edge of the bucket rel­a­tive to the body of the ma­chine and tar­get sur­face.

Two GNSS an­ten­nas are po­si­tioned on the handrails be­hind the cab, with the GNSS UHF dig­i­tal re­ceiver in­side the cab. All data is then dis­played on a 12.1-inch touch­screen con­troller.

As the ex­ca­va­tor’s bucket edge ap­proaches the tar­get sur­face, the iMC sys­tem’s au­to­mated fea­tures take over. Auto grade as­sist uses the boom to ad­just bucket height au­to­mat­i­cally as the arm moves, min­imis­ing over-ex­ca­va­tion. Auto stop con­trol stops the ma­chine dur­ing boom, arm or bucket op­er­a­tion once the bucket edge reaches the tar­get sur­face.
