Sany SR250 rotary drilling rig tuaj yeem hloov ntawm rotary drilling txoj kev thiab CFA (nruam davhlau auger) txoj kev tom qab hloov cov khoom siv sib txawv (xov cov kav dej).
Sany SR250 rotary drilling rig yog ib qho kev ua haujlwm ntau thiab ua haujlwm zoo cast-in-place pile drilling khoom. Nws yog dav siv nyob rau hauv kev tsim kho ntawm pawg hauv paus tej yaam num xws li kev txuag dej, vaj tse siab, kev tsim kho hauv nroog, kev tsheb ciav hlau, txoj kev loj thiab txuas hniav.
Lub SR250 rotary drilling rig tsim los ntawm Sany Heavy Machinery Co., Ltd. txais yuav hydraulic expandable crawler chassis uas ua los ntawm kab ntsig, uas tuaj yeem tshem tawm thiab poob los ntawm nws tus kheej, quav lub mast, tau kho qhov perpendicularity, tuaj yeem ntes lub qhov tob, ncaj qha. tso saib cov kev ua haujlwm hauv lub xeev ntawm lub vijtsam kov thiab saib xyuas, thiab tag nrho lub tshuab ua haujlwm tau txais kev tswj xyuas hydraulic thiab PLC automation ntawm load sensing, uas yog yooj yim, dexterous thiab tswv yim.
