Ama-excavator amancane angenye yezinhlobo zemishini ekhula ngokushesha, nokuduma komshini kubonakala kukhula njalo.Ngokusho kwedatha evela ku-Off-Highway Research, ukuthengiswa komhlaba wonke kwe-mini excavator bekusezingeni eliphakeme kunawo wonke ngonyaka odlule, ngamayunithi angaphezu kuka-300,000.
Izimakethe ezinkulu zabavubukuli abancane ngokwesiko bekungamazwe athuthukile, njengaseJapane nalawo aseNtshonalanga Yurophu, kodwa kule minyaka eyishumi edlule ibone ukuthandwa kwazo kukhula emazweni amaningi ezomnotho asafufusa.Okuphawuleka kakhulu kulawa yiShayina, manje osekuyimakethe enkulu kakhulu yokumba ama-mini emhlabeni.
Uma kubhekwa ukuthi izimbiwa ezincane zithatha indawo yemisebenzi yezandla, lokhu mhlawumbe ukuguquguquka okumangazayo ezweni elinabantu abaningi emhlabeni lapho kungekho khona ukushoda kwabasebenzi.Nakuba konke kungase kungabi njengoba kubonakala emakethe yaseShayina – bheka ibhokisi elithi 'I-China nama-mini excavators' ukuze uthole imininingwane eyengeziwe.
Esinye sezizathu zokuduma kwe-mini excavator ukuthi kulula ukunika amandla umshini omncane futhi ohlangene ngogesi kunogesi wendabuko.Kunjalo ukuthi, ikakhulukazi ezindaweni zamadolobha ezomnotho ezithuthukile, kuvame ukuba nemithetho eqinile ephathelene nomsindo nokungcoliswa kwesisi esikhipha umoya.
Akukho ukushoda kwama-OEM asebenzayo njengamanje, noma akhiphe ama-excavators amancane kagesi - emuva ngoJanuwari 2019 I-Volvo Construction Equipment (Volvo CE) yamemezela ukuthi, maphakathi no-2020, izoqala ukwethula uhla lwezimbambi ezihlangene zikagesi ( EC15 kuya ku-EC27) nezilayishi ezinamasondo (L20 kuya ku-L28) futhi zimise ukuthuthukiswa okusekelwe enjinini kadizili yalezi zinhlobo.
Enye i-OEM ebheka amandla kagesi kule ngxenye yemishini yi-JCB, enezimbambi ezincane zikagesi ze-19C-1E zenkampani.I-JCB 19C-1E inikwa amandla amabhethri e-lithium-ion amane, ahlinzeka ngo-20kWh wokugcina amandla.Lokhu kwanele ukushintsha ukusebenza okugcwele kuningi lamakhasimende ama-mini excavator ngenkokhiso eyodwa.I-19C-1E ngokwayo iyimodeli enamandla, ehlangene ekhipha umoya oyiziro endaweni yokusetshenziswa futhi ethule kakhulu kunomshini ojwayelekile.
