Wahi a nā helu helu mai China Construction Machinery Industry Association, ʻo nā mea hana excavator 25 kiʻekiʻe loa i hoʻokomo ʻia i ka helu ma Dekemaba 2020 i kūʻai aku i 31,530 excavators o nā ʻano like ʻole, hoʻonui i ka makahiki o 56.4%;he 27,319 o loko o ia mau hale, he 58.5% ka nui o ka makahiki ma ka makahiki;he 4,211 ka hoʻokuʻu ʻana, he piʻi makahiki ma ka makahiki He piʻi o 44.4%.

Mai Ianuali a Dekemaba 2020, ua kūʻai ʻia ka huina o 327,605 excavators, kahi hoʻonui makahiki o 39%;ʻO ia, he 292,864 ka home, he piʻi makahiki i ka makahiki he 40.1%;a he 34,741 i lawe ʻia aku i waho, he piʻi makahiki o ka makahiki he 30.5%.

Mai ka ʻikepili, hiki iā mākou ke ʻike i ka ulu ʻana o nā mīkini kūkulu hale o Kina, ʻoi aku ka nui o nā excavators, he mea nui loa.Ke alakaʻi ʻia e ka ulu ʻana o ka mākeke host, nā ʻāpana ʻokoʻa, ʻoi aku ka nui o nā ʻāpana hydraulic, ua ulu nui.E ulu pū ana nā mīkini hydraulic i hana ʻia e Weitai Hydraulics e kūʻē i ke ʻanoi 2020 a ua loaʻa i nā hopena koʻikoʻi.

E hoʻomau ka hui ʻo Weitai i ka hoʻoulu ʻana i ka ʻoihana hydraulic, e pili ana i nā motika hydraulic a me nā valve pump hydraulic ma ke ʻano he breakthrough point, a hoʻomau i ka hoʻomaikaʻi ʻana i kā mākou hōʻiliʻili ʻana i nā hydraulics mobile, a hāʻawi i nā haʻawina hou aku i ka China Mobile Hydraulics.
