\n\t\t\t\t\t\tKomatsu e o companie japonez\u0103 cu o reputa\u0163ie impecabil\u0103 \u00een produc\u0163ia de vehicule miniere mari, dar acum divizia sa din Germania a fost cea care a lansat global cel mai mare excavator hidraulic minier, numit Komatsu PC9000. \u015ei asta pentru c\u0103 actuala fabric\u0103 principal\u0103 produc\u0103toare de asemenea echipamente se afl\u0103 \u00een Dusseldorf, Germania, \u015fi a fost c\u00e2ndva construit\u0103 de produc\u0103torul german Orenstein & Koppel, sau O&K. Ei bine, noul excavator face un salt imens de capacit\u0103\u0163i \u015fi parametri \u015fi poate \u00eenc\u0103rca p\u00e2n\u0103 la 80 tone de minereu printr-o singur\u0103 mi\u015fcare a cuvei sale.\n\t\t\t\t\t<\/p>\n

Noul excavator nu reprezint\u0103 o \u00eenlocuire a unui model mai vechi, ci o intrare a celor de la Komatsu \u00eentr-un segment nou al celor mai mari excavatoare din lume. Komatsu are modelul PC8000, de aproape 800 tone mas\u0103 opera\u0163ional\u0103, sau 768 tone dac\u0103 e s\u0103 fim mai exac\u0163i.\n\t\t\t\t\t<\/p>\n

Doar c\u0103 \u015fi Liebherr are deja un model mai mare, R9800, de exact 800 tone mas\u0103 opera\u0163ional\u0103, Hitachi are EX8000-8, care are minim 800 tone, dar poate fi configurat\u0103 \u015fi la c\u00e2teva zeci de tone mai mult.\n\t\t\t\t\t<\/p>\n

Iar mastodontul din segment e Caterpillar 6090 FS, care are 1.100 tone, dar care e u\u015for prea mare pentru unele aplica\u0163ii. Caterpillar 6090 FS are o cuv\u0103 de 52 metri cubi volum \u015fi poate \u00eenc\u0103rca 93,5 tone dintr-o mi\u015fcare, av\u00e2nd dou\u0103 motoare Cummins de 4.500 CP for\u0163\u0103 cumulat\u0103. Cei de la Komatsu \u015fi-au dovedit ceva apropiat de capabil, dar mult mai versatil.\n\t\t\t\t\t<\/p>\n

Noul excavator Komatsu a fost proiectat \u015fi fabricat \u00een Germania, la acea fabric\u0103 din Dusseldorf, men\u0163ionat\u0103 mai sus. De acolo vor avea lor \u015fi livr\u0103rile la nivel global spre minele din \u00eentreaga lume.\n\t\t\t\t\t<\/p>\n

\n\t\t\t\t\t\tEl poate avea cuva \u00eendreptat\u0103 frontal, cu din\u0163ii \u00een fa\u0163\u0103, sau invers, \u00een func\u0163ie de sarcinile pe care le are de \u00eendeplinit. \u00centr-un caz are 46 metri cubi \u00een volum, iar \u00een al doilea \u2014 49 metri cubi.\n\t\t\t\t\t<\/p>\n

\n\t\t\t\t\t\tDintr-o singur\u0103 excavare sau \u00eenc\u0103rcare a cuvei, excavatorul poate lua \u00een ea 80 de tone de greut\u0103\u0163i, fapt care e foarte util atunci c\u00e2nd se \u00eencarc\u0103 pietre sau minereu de fier cu densitate foarte mare.\n\t\t\t\t\t<\/p>\n

\n\t\t\t\t\t\tExcavatorul e optimizat pentru a putea s\u0103 \u00eencarce un camion minier de top, precum Komatsu 980E, \u00een doar 5 \u00eenc\u0103rc\u0103ri ale cuvei, care dureaz\u0103 \u00een total 150 de secunde. Deci, productivitate \u015fi randament maxim, cu 8.000 tone de material \u00eenc\u0103rcat pe or\u0103.\n\t\t\t\t\t<\/p>\n

\n\t\t\t\t\t\tNoul excavator are propulsia elementelor sale principale de munc\u0103 printr-un sistem obi\u015fnuit hidraulic, care e pus \u00een mi\u015fcare fie de dou\u0103 motoare diesel a c\u00e2te 2.100 CP, fie de dou\u0103 motoare electrice, de 1.970 CP fiecare. \u00cen al doilea caz, excavatorul nu are baterii, ci e conectat la re\u0163eaua electric\u0103 local\u0103 acolo unde munce\u015fte.\n\t\t\t\t\t<\/p>\n

\n\t\t\t\t\t\tPentru c\u0103 \u00een acest domeniu fiabilitatea conteaz\u0103 enorm, Komatsu a creat acest nou excavator acum doi ani, apoi a livrat primul exemplar construit, cu statul de prototip, \u00een Canada, unde acesta a muncit sub observa\u0163ie, pentru ca inginerii s\u0103 se asigure c\u0103 nu exist\u0103 vulnerabilit\u0103\u0163i de durabilitate. Apoi a urmat \u015fi un al doilea exemplare de test livrat tot \u00een Canada. \u015ei abia acum a avut loc \u015fi lansarea oficial\u0103 complet\u0103.\n\t\t\t\t\t<\/p>\n
