Ama-SM1100 ama-rigging hydraulic crawler rigs amisiwe nge-rotation-percussion rotary head noma i-torque enkulu yokujikeleza uhlobo lwe-rotary head njengenye indlela, futhi ifakwe isando esiphansi, esenzelwe ukusebenza kwemigodi ehlukahlukene. Ilungele isimo esihlukile senhlabathi, isibonelo ungqimba lwamatshebula, idwala eliqinile, i-aquifer, ubumba, ukugeleza kwesihlabathi njll. Lesi sigxobo sisetshenziselwa kakhulu ukubhola ukushayisana kwe-percussion kanye ne-rotation ejwayelekile ejwayelekile kuphrojekthi yokuxhasa ibhawodi, ukusekelwa kwethambeka, ukuzinza kokuqina, imbobo yezulu kanye nezinqwaba ezingaphansi komhlaba, njll.
