I-Zoomlion GJ-1 Overwind Protection Switch iyingxenye yokuphepha ebalulekile yokuphakamisa izinto zokusebenza. Uma ihuku ifinyelela endaweni yayo ephezulu yomkhawulo, iswishi iqala ngokushesha ukunqamula isekethe yokulawula i-hoist, ivimbele izingozi ezimbi njengokuphuka kwentambo yensimbi noma ukuwa kwehhuku okubangelwa ukugingqika.

I-GJ-1 Anti-Overwinding Switch iyidivayisi yokuvikela eklanyelwe ngokuqondile okokusebenza kobunjiniyela, esetshenziswa ngokuyinhloko ezindleleni zokuphakamisa ama-cranes ahambayo, ama-crawler cranes, nemishini efanayo. Icupha ngokuzenzakalelayo lapho ihuku ifinyelela endaweni ebekiwe ephezulu yomkhawulo, inqamula ugesi ukuvimbela ukulimala kwemishini kanye nezingozi zokuphepha ezidalwa ukugingqika kwentambo yezintambo. Kuyingxenye eyinhloko yokuqinisekisa imisebenzi yokuphakamisa ephephile.

I-GJ-3 Overwind Limit Switch iyidivayisi yokuvikela eklanyelwe ngokukhethekile ukuphakamisa izinto zokusebenza. Umsebenzi wayo oyinhloko ukuvimbela izingozi ezifana nokugingqika kwentambo yentambo, ukuphuka, noma ukulimala kwethuluzi lokuphakamisa okubangelwa ihuku elingaphezu kwendawo yalo yomkhawulo ephezulu. Ifaka ukwakhiwa kwezindlu zensimbi kanye nemishini yokuqalisa, inikeza impendulo ebucayi, ukusetha kabusha okulula, nokusebenza okuthembekile, okuyenza ingxenye yokuphepha ebalulekile emisebenzini yokuphakamisa izimboni.

Lena idivayisi yoqobo yokuvikela engenantambo efakwe efekthri yemishini yokhreyini egibele iloli ye-XCMG. Iqapha ukuphakama kwe-boom ngesikhathi sangempela, icuphe i-alamu ezwakalayo nokubukwayo futhi inqamule ukunyakaza okuyingozi lapho ukuphakama kokuphakama kusondela embundwini obalulekile. Lokhu kuvimbela ngempumelelo izingozi zokuphepha ezifana nokuphuka kwentambo yezintambo ngenxa yokugingqika kanye nokulimala kwe-boom kusuka ekunwetshweni ngokweqile, okuyenza ibe yingxenye eyinhloko yemisebenzi yokuphakamisa ephephile.

Lolu cingo luyingxenye yokuvikela ukuphepha eyenzelwe okokuphakamisa izinto ezahlukene. Isebenzisa inzwa yesisindo ukuze ithole indawo yehuku. Lapho ihuku ikhuphukela ekuphakameni osethiwe, inqamula ngokuzenzakalelayo isekethe yamandla okuphakamisa ukuvikela ukungqubuzana phakathi kwehhuku nangaphezulu kwe-boom (anti-two block/anti-overwinding), ivikela ngempumelelo okokusebenza nokuphepha kwabasebenzi. Yakhelwe ngokuvikela izinga lezimboni, imelana nezimo ezinzima zokusebenza zangaphandle zemishini yokwakha futhi iyisici esiyisibopho esidingekayo ngokuphakamisa imithetho yokuphepha kwemishini.

Lo mkhiqizo uyidivayisi yokuvikela ukuphepha eyakhelwe imishini yokwakha. Umsebenzi wawo oyinhloko ukuvimbela amahhuku e-crane ukuthi angawi ngaphezulu ngesikhathi sokukhuphuka, ukugwema ukuphuka kwentambo yensimbi noma ukulimala kwempahla. Yakhelwe ngezindlu ezisezingeni eliphezulu ezisezingeni lezimboni kanye nesakhiwo esinembayo sokucupha imishini, isebenza ngokwethembeka ezimweni eziyinkimbinkimbi zokusebenza ezihlukene, okuyenza ibe yingxenye yokuphepha ebalulekile yama-cranes, ama-tower cranes, nezinye izinto zokusebenza zokuphakamisa.

Idizayinelwe ngokukhethekile i-SANY kanye nezinhlobo ezihlukahlukene zemishini yokuphakamisa, lena idivayisi yokuphepha eyinhloko ukuvimbela ukuhamba kwe-hook nokuqinisekisa ukuphepha ekwakhiweni.

Lo mkhiqizo uyisinqamuli sobude sangempela esifaniswa nefekthri (iswishi evimbela ukugeleza kwamanzi) samakhreni amaloli e-SANY, aklanyelwe ngokukhethekile ukusebenza okuphephile kwama-crane. Uma ihuku ikhuphukela ekuphakameni osethiwe, idivayisi inqamula ngokuzenzakalelayo isekethe yokuphakamisa i-hoist bese icupha i-alamu ezwakalayo-nokubukwayo, ivimbele izingozi zokuphepha ezifana nokudlula kwehhuku nokuphuka kwentambo yezintambo. Kuyidivayisi yokuvikela ukuphepha ebalulekile ekusebenzeni kokuphakamisa.

I-SANY GJ-1 Overwind Switch iyidivayisi yokuvikela eklanyelwe ngokukhethekile ukuphakamisa imishini. Ngokugada ngesikhathi sangempela indawo yehuku, inqamula ngokushesha isekethe yokulawula yokuphakamisa lapho ukuphakama komkhawulo osethiwe kufinyelelwa, ivimbela ngokuyisisekelo izingozi ezifana nokugingqika kwentambo yensimbi, ukuphuka nokweqa kwehhuku. Inikeza ukuvikelwa okuthembekile kwemishini nokuphepha kwabasebenzi. Lo mkhiqizo uhambisana nalo lonke uchungechunge lwama-SANY cranes, ama-crawler cranes, okhreni bamaloli kanye nemishini yokuphakamisa ichweba, equkethe izinga eliphezulu lokuvikela kanye nekhono eliqinile lokulwa nokuphazamiseka ukuze livumelane nezimo ezihlukahlukene zokusebenza eziyinkimbinkimbi.

I-Raico Wireless Anti-Overwind Limit Switch iyisisetshenziswa sokuvikela ukuphepha esiklanyelwe ngokukhethekile ukuphakamisa imishini efana nokhreni bamaloli kanye nama-mobile cranes. Ukwamukela ubuchwepheshe bokudlulisa okungenantambo, kuqeda isidingo sezintambo eziyinkimbinkimbi. Uma ihuku ikhuphukela ekuphakameni komkhawulo osethiwe, inqamula amandla ngokuzenzakalelayo futhi icuphe i-alamu, ivimbele ngempumelelo izingozi ezifana nentambo yensimbi ewele phezulu kanye nokuphahlazeka kwehhuku. Kuyingxenye eyinhloko yokuqinisekisa ukuphepha kokusebenza kokuphakamisa.
