Perforatrici con centrale separata

Imisebenzi yokwakha, yokulungisa nokwakha izisekelo ezindaweni zasemadolobheni ivame ukufuna ukusetshenziswa kwemishini ethile, ekwazi ukufinyelela ngaphakathi ezindaweni ezivalekile (kaningi ezindaweni eziphansi) futhi ukusebenza ezimeni zokukhula okuncane kakhulu. Ukuze kuhlangatshezwane nalezi zidingo, ibhande le-Comacchio linikeza ukukhetha okuningi kwe-perforators ye-hydraulic enezikhungo zamandla ezihlukile (ezifakwe kumakhalekhukhwini noma ezinqolobaneni) ezingabekwa kuze kufike ku-30 m ukusuka kwi-sonda, kunciphisa kakhulu ubukhulu bemishini. Ubukhulu beyunithi yokubhoboza bungenziwa buncishiswe ngaphezulu ngokusebenzisa ama-subframes anobubanzi obuhlukahlukene. Ngokubeka isikhungo samandla kude, kuvinjwa futhi ukukhishwa kwegesi ngaphakathi kwendawo yokwakha. Ukukhishwa kungaqedwa ngokuphelele ngokusebenzisa ama-motors kagesi, atholakala kumamodeli wonke aleli qembu. I-perforators enezikhungo ezihlukile ze-Comacchio ifakwe uhlelo lwe-cinematism oluphelele oluvumela ukufinyelela ezindaweni ezihlukahlukene nezikhala ze-mast. Zonke izimodeli zifanele ukusetshenziswa kwezindlela ezivamile zokubhoboza ezijikayo nezijikayo.
