I-High Reach Demolition Crawler Excavators: PC490HRD-11

UKomatsu usanda kwethula i-PC490HRD-11 yokumba indawo ephezulu emakethe yaseNyakatho Melika. Ifakwe injini ye-Komatsu enamandla angu-362 enikeza izindlela zokusebenza eziyisithupha ezihlukene, le modeli ifakwe i-telescopic boom eyenza ububanzi bokusebenza obuphezulu kanye nokujula okukhulu kokumba.

Ngokunamathiselwe kwe-5,511 lb (cishe amathani angu-2.5), ubude be-boom bunganwetshwa bufinyelele ku-104 ft (approx. 32 m); isistimu yokulawula ithuluzi ingagcina ingcindezi eqondile nezilungiselelo zokugeleza kufika kokunamathiselwe okungu-15. Ukwengeza, idizayini ye-undercarriage retractable hydraulically ivumela isikhala sethrekhi esincane ukuze kube lula ukuhamba.

UKomatsu uthi i-K100 Quick Boom Change System ekhethwayo inika amandla izinguquko ze-boom zamahhala ngemizuzu. Isistimu ilungiselelwe ngezixhumi ezisheshayo ze-hydraulic ezinciphisa ingcindezi yokubuya kanye nezinga lokushisa likawoyela ngaphandle kokukhawulela ukugeleza koketshezi. Uhlelo luphinde lufakwe iphinikhodi ye-hydraulic drive efakwe ngaphakathi kwesakhiwo esikhulu se-telescopic boom, esiza ukunciphisa ubungozi bokulimala kwemishini ngesikhathi sokulungiswa kabusha.

Nge-K100, konke ukuxhuma, kungakhathaliseki ukuthi okomshini, okuqhutshwa ngamanzi noma kukagesi, kwenziwa ngokuzenzakalelayo ngaphandle kwesidingo sokungenelela ngokusebenza. NgokukaKomatsu, i-human-machine interface (HMI) iqinisekisa ukuthi isimo somshini saziwa kulo lonke uhlelo nokuthi ukuziphatha komshini kuhlale kubikezelwa. Noma kunini, u-opharetha angaphuma kunqubo futhi abuyele esimweni sangaphambilini.

Ukushintsha okusheshayo kwama-booms ngohlelo lwe-K100 kuzokwenza osonkontileka bacabange kabusha izindlela abazisebenzisayo emisebenzini yokubhidliza. Isibonelo, ama-booms afinyelela isikhathi eside angasetshenziswa ezingxenyeni ezinde zesakhiwo; lapho kudingeka amandla amakhulu okubhidliza, ukushintshwa okusheshayo ku-boom emfushane kungenziwa ukuze kwethulwe amathuluzi okubhidliza asindayo, anamandla kakhulu. Ngaphezu kwalokho, i-excavator efanayo ingalayishwa ngezinto zokuthutha, ukonga izindleko zokusebenza kusayithi.

Ukulawula i-Joystick kuvumela ikhebhu ukuthi itsheke ifike kumadigri angu-30 ukuze igcine umbono omuhle wendawo yokusebenza. I-PC490HRD-11 ifakwe nohlelo lokubuka iso lenyoni ye-Komatsu's KomVision ukuze kuthuthukiswe ukubonakala kwendawo yokuphepha ezungeze umshini. Izibani ze-LED ozikhethela zona zithuthukisa futhi ukubonakala.

I-PC490HRD-11 ifakwe onogada baseceleni abangaguquki obungu-15mm obukhulu obushintshwayo, abangashintshwa kalula uma bonakele; wonke umshini ubuye ube nesilinda sokuphakamisa i-boom esinobukhulu obungama-25mm; futhi ingaphansi le-excavator nalo livikelekile, ngonogada abangu-9mm obukhulu.

I-PC490HRD-11 Iphansi lonke lomshini livikelekile ukuze kuvinjwe umonakalo ovela emfucumfucwini ephansi. Ukwengeza ezimweni eziphakeme ze-boom, isakhiwo esiphansi se-PC490HRD-11 siyaqiniswa ukuze sibhekane ne-counterweight enkulu kanye namandla amade okulinganisa ngaphambili kwe-telescopic boom.
