I-JCB yethule i-mini excavator yayo yokuqala kagesi egcwele, i-19C-1E – imodeli ethule kakhulu, enamandla futhi ehlangene engenawo ukukhishwa komoya. Isebenzisa ubuchwepheshe bebhethri yezimoto obuhamba phambili, i-JCB ithi i-19C-1E izoletha konke ukusebenza kwe-mini excavator ejwayelekile enamandla angu-1.9-tonne esebenzisa udizili ngokunciphisa amazinga omsindo angaphakathi nangaphandle.
Yakhelwe ukuhlangabezana nesidingo esikhulayo semishini yokwakha enobungani nemvelo, i-19C-1E inamabhethri amathathu noma amane e-lithium-ion anikeza amandla okugcina angu-15-20kWh. Amabhethri anesistimu yokuphatha eyinkimbinkimbi inkampani ethi iqinisekisa ukutholakala kwe-full shift kanye neshaja esebhodini enokufakwa kwe-110V kokushaja kabusha kwamahora angu-12 kanye nenketho yokushaja amahora angu-8 e-230V uma kudingeka. I-JCB ithi kukhona futhi inketho yokushaja okusheshayo evumela ukushaja okuphelele ngaphansi kwamahora amabili.
“Imishini kagesi inendima ebalulekile okufanele iyidlale emkhakheni wokwakha ikakhulukazi ngokwanda kokufudukela kwabantu emadolobheni lapho isebenza khona eduze nabantu, igubha ngaphansi komhlaba nangaphakathi,” kusho u-Alan Tolley, umqondisi wezinjini zeqembu le-JCB, etshela i-UKPO. “Inzuzo eyodwa ukuthi izovumela osonkontileka bezitimela ukuthi basebenze emihubheni nangaphansi komhlaba, ngaphandle kokufaka imishini yokukhipha ugesi ebizayo. Imishini kagesi idinga isikhathi sokuvuselela, ngakho-ke lokhu kufanele kubhekwe ephethini yokusebenza. Kodwa-ke lokhu akuyona inkinga ngokuvamile esigabeni se-mini excavator, kodwa kungaba ngezinye izinhlobo zemishini ezisetshenziswa kakhulu kwimodi yenqubo eqhubekayo.”
Ngakho-ke imishini kagesi izongena kanjani kulesi simo sisonke? “Ugesi uzoba nendima okufanele uyidlale kodwa ubuchwepheshe bedizili ehlanzekile buzoqhubeka nokunika amandla iningi lemishini,” kusho u-Alan. “Uma uqhathanisa ugesi nodizili, izinjini zikadizili zakamuva ze-Stage V JCB cishe ziqede ukukhishwa okuyingozi, kanti i-NOx yehle ngo-97% kanti izinhlayiya ze-soot zehle ngo-98% uma kuqhathaniswa neminyaka engama-20 eyedlule. Siphinde sanciphisa ukukhishwa kwe-CO2 cishe ngesigamu (ukuthuthuka okungadingeki ngokomthetho) ngokuthuthukisa ukusebenza kahle kwemishini nenjini. Ngakho-ke ngedizili, sisendleleni eya ku-zero.”
Injini kagesi entsha ye-19C-1E esebenza kahle kakhulu inikeza i-torque esheshayo ukuze inike amandla uhlelo lwe-hydraulic lwe-Bosch Rexroth oluzwa umthwalo. I-JCB ithi lokhu kunikeza ukusebenza okufanayo kokumba njenge-19C-1 ejwayelekile. Uhlelo lwe-hydraulic luphinde lunikeze isekethe esiza ukugeleza okuphindwe kabili esingamalitha angu-32/min kanti i-mini iza nenketho yesekethe yamathuluzi e-hydraulic ehlanganisiwe ephethwe ngesandla, ukuze kube nokuguquguquka okwengeziwe.
Umshini unezindlela ezintathu zokumba, ezilawulwa nge-dial ejikelezayo. Esimisweni 'esiphansi' injini kagesi isebenza ku-1,200 rpm; 'ngokujwayelekile' isebenza ku-1,600 rpm kanti 'esiphezulu' injini ijikeleza ku-1,800 rpm. Kukhona imodi eyengeziwe ye-Auto Kick Up yokulandelela, lapho injini isebenza ku-2,300 rpm yokunyakaza okusheshayo phakathi kwezindawo zokumba.
