01 Uhlobo kanye nomsebenzi wendandatho yokulenga

Indandatho yokulenga ingahlukaniswa ibe yindandatho yokulenga engalweni eyodwa kanye nendandatho yokulenga engalweni ezimbili ngokwesakhiwo. Umsebenzi wayo oyinhloko ukumisa i-hanger ukuze ibambe i-drill lapho i-drill idonswa phansi. Njenge-DH150, i-SH250, lapho u-D emele ingalo eyodwa, u-S emele izingalo zombili, u-H umele indandatho, u-150, u-250 umele umthwalo olinganisiwe wendandatho, iyunithi ingu-9.8×103N (tf).

Izinyathelo zokuphepha zokusebenzisa izindandatho zokulenga

(1) Indandatho kumele isetshenziswe ngamabili, hhayi ngokuhlanganiswa, futhi umehluko wobude obusebenzayo bendandatho entsha akufanele ube ngaphezu kuka-3mm; Umehluko phakathi kobude obusebenzayo bendandatho ezimbili ezisetshenziswayo akufanele ube ngaphezu kuka-5mm (ubude obusebenzayo bubhekisela ebangeni eliphakathi kwendawo yokuxhumana yendlebe engenhla yendandatho kanye nendlebe eseceleni ye-hook kanye nendawo yokuxhumana yendlebe engezansi kanye ne-lifti; Umehluko wobude obusebenzayo ubhekisela ebangeni lobude obusebenzayo bendandatho).

(2) Khetha indandatho efanele ngokwezidingo zomthwalo, bese wenqabela ukusetshenziswa ngokweqile.

(3) Indandatho akumele ibe nemifantu kanye nokushibiliza.

(4) Uma ubhoboza, amasongo amabili kufanele aboshwe ndawonye ukuze angashukumi futhi ashayeke empompini.

(5) Ngemva kokusingatha izingozi noma ukuphakamisa okunamandla (okungaphezu kwezikhathi ezingu-1.25 zomthwalo olinganisiwe wendandatho yokulenga), kufanele imiswe, futhi kufanele ihlolwe futhi ihlolwe.

(6) Indandatho yokulenga kufanele ibe nezinga elithile lenkululeko yokujikijela endlebeni ye-hook, kanye nesimo sekhadi elingenazithiyo.

(7) Indandatho yokuphakamisa kufanele iboshwe ngentambo yocingo lokuphepha ehukwini.
