01 Uhlobo kunye nomsebenzi weringi yokuxhoma

Indandatho yokuxhoma ingahlulwa ibe yindandatho yokuxhoma enengalo enye kunye nendandatho yokuxhoma enengalo ezimbini ngokwesakhiwo. Umsebenzi wayo ophambili kukuxhoma i-hanger ukuze ibambe i-drill xa i-drill itsalwa phantsi. Ezifana ne-DH150, i-SH250, apho u-D emele ingalo enye, u-S emele zombini iingalo, u-H umele indandatho, u-150, u-250 umele umthwalo olinganisiweyo wendandatho, iyunithi yi-9.8×103N (tf).

Amanyathelo okusebenzisa iiringi zokuxhoma

(1) Indandatho mayisetyenziswe ngababini, ingadibani, kwaye umahluko wobude obusebenzayo bendandatho entsha awuyi kuba ngaphezu kwe-3mm; Umahluko phakathi kobude obusebenzayo bendandatho ezimbini ezisetyenziswayo awuyi kuba ngaphezu kwe-5mm (ubude obusebenzayo bubhekisa kumgama ophakathi kwendawo yoqhagamshelwano yendlebe ephezulu yendandatho kunye nendlebe esecaleni yehoko kunye nendawo yoqhagamshelwano yendlebe esezantsi kunye nelifti; Umahluko wobude obusebenzayo ubhekisa kumahluko kubude obusebenzayo bendandatho ezimbini).

(2) Khetha iringi efanelekileyo ngokweemfuno zomthwalo, kwaye ungavumeli ukusetyenziswa ngokugqithisileyo.

(3) Indandatho ayifanele ibe neentanda kunye neentsimbi.

(4) Xa kugqojozwa, izangqa ezimbini mazibotshelelwe kunye ukuze zingashukumi kwaye zingabetheki kwimpompo.

(5) Emva kokusingatha iingozi okanye ukuphakamisa ngamandla (ngaphezulu kwe-1.25 amaxesha omthwalo olinganisiweyo weringi yokuxhoma), kufuneka imiswe, kwaye kufuneka ihlolwe kwaye ihlolwe.

(6) Indandatho yokuxhoma kufuneka ibe nenkululeko ethile yokujika kwi-earring ye-hook, kunye nemeko yekhadi elingenaziphazamiso.

(7) Indandatho yokuphakamisa kufuneka ibotshelelwe kwintambo yocingo lokhuseleko kwihoko.
