I-Tower Crane Undercarriage Base: I-Critical Structural Core Inquma Ukusebenza Komshini Sekukonke Njengengxenye eyisihluthulelo ethwala umthwalo kanye nengxenye yokuxhuma yama-cranes ombhoshongo, isisekelo se-undercarriage sixhumanisa isisekelo, isistimu yokubulala kanye nomzimba wombhoshongo, othwala yonke imithwalo yawo wonke umshini ngesikhathi sokusebenza. Ikhwalithi yengxenye yayo yesakhiwo iyisiqinisekiso esiyinhloko sokuphepha nokusimama kombhoshongo we-crane. Ikhwalithi enhle kakhulu yesakhiwo iqinisekisa ukudluliswa komthwalo okunembile, ukushaya okuzinzile kanye nokusebenza okuthembekile kwesikhathi eside kwawo wonke umshini; izingxenye zesakhiwo ezisezingeni eliphansi zizodala ukudlidliza kokusebenza, ukuchezuka okunembayo, futhi kuholele nasekuhlulekeni kwesakhiwo, kubeke engozini ukuphepha kwawo wonke nempilo yesevisi. Izingxenye zesakhiwo zesisekelo se-undercarriage esezingeni eliphakeme = ukusebenza okuzinzile, okuphephile nokuqinile kwe-crane yombhoshongo.

Izingxenye Zesakhiwo Se-Rotary Drilling Rig: Ukhiye Wokusebenza Kukonke Komshini Nokuphepha Kokwakhiwa Izingxenye Zesakhiwo ziyizingxenye ezibalulekile ezithwala umthwalo nezisebenzayo zezinsimbi zokumba ezijikelezayo, ezithwala yonke imithwalo eyinkimbinkimbi ngesikhathi sokumba futhi zisekela ukusebenza okuvamile kwawo wonke umshini. Izinga lezingxenye zesakhiwo liyisiqinisekiso esiyinhloko sokuzinza, ukunemba nokuphepha kwe-rotary drilling rig. Izingxenye zesakhiwo ezisezingeni eliphezulu ziqinisekisa umthamo oqinile wokuthwala umthwalo, isakhiwo esizinzile kanye nokunemba okuphezulu kokumba, okuvumela ukwakhiwa okuphumelelayo ezigabeni ezihlukahlukene; izingxenye zesakhiwo esingaphansi zizodala ukuguquguquka, ukuxhuma okuxekethile kanye nokunemba okuphansi kokusebenza, okuholela ekubambezelekeni kokwakhiwa, izindleko ezikhulayo kanye nezingozi ezingaba khona zokuphepha. Izakhi ze-Premium structural = Ukusebenza okuzinzile, okuphumelelayo nokuphephile kwe-rotary drilling rig.
