I-excavators encinci yenye yeentlobo zezixhobo ezikhula ngokukhawuleza, kwaye ukuthandwa kwabo kubonakala kuqhubeka kukhula. Ngokutsho kwedatha evela kwi-Off-Highway Research, intengiso yehlabathi jikelele ye-excavators encinci ifikelele kwindawo ephezulu kunyaka ophelileyo, idlula iiyunithi ze-300,000.
Ngokwesiko, iimarike eziphambili ze-micro-excavators ziye zaphuhliswa amazwe, afana neJapan kunye neNtshona Yurophu, kodwa ukuthandwa kwabo kumazwe amaninzi asakhulayo kuye kwanda kwiminyaka elishumi edlulileyo. Eyona idumileyo kwezi yi-China, ngoku eyeyona marike inkulu ye-mini excavator.
Ukuthathela ingqalelo into yokuba abembi bezinto ezincinci banokuthatha indawo yomsebenzi wezandla, ngokuqinisekileyo akukho ukunqongophala kwabasebenzi kwezona ndawo zinabantu abaninzi ehlabathini. Oku kunokuba yinguqu emangalisayo. Nangona imeko isenokungafani nemarike yaseTshayina, nceda ujonge ikholamu ethi "China kunye nabembi abancinci" ngolwazi olungakumbi.
Esinye sezizathu ezibangela ukuba ii-excavators ezincinci zixhaphake kukuba kulula ukunika amandla oomatshini abancinci nabancinci kunye nombane kunamandla edizili. Kule meko, ngakumbi kumaziko asezidolophini oqoqosho oluphambili, ngokuqhelekileyo kukho imimiselo engqongqo kwingxolo kunye nokukhutshwa.
Akukho kunqongophala kwabavelisi be-OEM abaphuhlisayo okanye bakhulule abenzi bezinto zombane ezincinci-ekuqaleni kukaJanuwari ka-2019, iVolvo Construction Equipment Corporation (iVolvo CE) ibhengeze ukuba phakathi ku-2020, iya kuqalisa ukuphehlelela uthotho lwee-excavators ezihlangeneyo zombane (EC15 ukuya kwi-EC27). ) Kwaye abalayishi bamavili (L20 ukuya kwi-L28), kwaye bamisa uphuhliso olutsha lwale mifuziselo esekelwe kwiinjini zedizili.
Enye i-OEM ekhangela amandla kule ntsimi yezixhobo yi-JCB, exhotyiswe nge-19C-1E yombane omncinci we-excavator yombane. I-JCB 19C-1E inikwe amandla ngeebhetri ezine ze-lithium-ion, ezinokubonelela nge-20kWh yokugcina amandla.
