01 Uhlobo kunye nomsebenzi weringi ejingayo

Umsesane wokuxhoma unokwahlulwa ube ngumsesane wokuxhoma ongalo-nye kunye neringi ejingayo enengalo ephindwe kabini ngokwesakhiwo. Umsebenzi wayo ophambili kukumisa i-hanger ukubamba i-drill xa i-drill itsalwa phantsi. Ezifana ne-DH150, SH250, apho i-D imele ingalo enye, i-S imele zombini iingalo, i-H imele i-ring, i-150, i-250 imele umthwalo olinganisiweyo wendandatho, iyunithi yi-9.8 × 103N (tf).

Izilumkiso zokusetyenziswa kwamakhonkco okuxhoma

(1) Iringi kufuneka isetyenziswe ngababini, ingadityaniswanga, kwaye umahluko wobude obusebenzayo beringi entsha awuyi kuba mkhulu kune-3mm; Umahluko phakathi kobude obusebenzayo bamakhonkco amabini asetyenziswayo awuyi kuba mkhulu kune-5mm (ubude obusebenzayo bubhekisa kumgama phakathi kwendawo yokunxibelelana yendlebe engaphezulu yeringi kunye nendlebe esecaleni yehuku kunye nendawo yokunxibelelana Indlebe esezantsi kunye ne-elevator Ubude obusebenzayo umahluko bubhekiselele kumahluko kubude obusebenzayo besibini samakhonkco).

(2) Khetha iringi efanelekileyo ngokweemfuno zomthwalo, kwaye uthintele ukusetyenziswa komthwalo ogqithisileyo.

(3) Umsesane awuyi kuba nazo naziphi na iintanda kunye neentsimbi.

(5) Emva kokuphatha iingozi okanye ukuphakanyiswa okunamandla (ngaphezu kwe-1.25 amaxesha omthwalo olinganisiweyo wendandatho yokulenga), kufuneka imiswe, kwaye kufuneka ihlolwe kwaye ihlolwe.

(7) Iringi yokuphakamisa kufuneka ibotshelelwe kwintambo yocingo yokhuseleko kwihuku.
