Sinovo ili ndi makina obowola ozungulira a Sany SR250 ogulitsa. Chaka chopanga ndi 2014. Kutalika kwakukulu ndi kuya ndi 2300mm ndi 70m. Pakali pano, maola ogwira ntchito ndi maola 7000. Zida zili bwino ndipo zili ndi 5 * 470 * 14.5m friction kelly bar. Mtengo ndi $187500.00. Ngati mukufuna, chonde omasuka kulankhula nafe.
Sany SR250 rotary pobowola cholumikizira amatha kusinthana pakati pa njira kubowola rotary ndi CFA (continuous flight auger) pambuyo kusintha zipangizo ntchito zosiyanasiyana (bowola mapaipi).
Sany SR250 rotary pobowola makina obowola amitundumitundu komanso apamwamba kwambiri pobowola mulu. Amagwiritsidwa ntchito kwambiri pomanga ma projekiti a maziko a milu monga ma projekiti osungira madzi, nyumba zazitali, zomangamanga zamatawuni, njanji, misewu yayikulu ndi milatho.
SR250 Rotary pobowola cholumikizira opangidwa ndi Sany Heavy Machinery Co., Ltd. utenga hydraulic expandable crawler chassis opangidwa ndi mbozi, amene akhoza kunyamuka ndi kugwa palokha, pindani mlongoti, basi kusintha perpendicularity, basi kudziwa dzenje kuya, mwachindunji. wonetsani magawo omwe akugwira ntchito pa zenera logwira ndikuyang'anira, ndipo makina onse ogwiritsira ntchito amatengera kuwongolera kwa hydraulic woyendetsa ndi PLC automation ya load sensing, yomwe ili yabwino, yaukadaulo komanso yothandiza.
