I-crane hook lolona hlobo luxhaphakileyo lwe-spreader kwi-hosting machine. Ihlala ixhonywe kwintambo yocingo yendlela yokuphakamisa ngokusebenzisa i-pulley blocks kunye namanye amacandelo.
Iigwegwe zinokwahlulwa zibe ngamagwegwe angatshatanga kunye neekhonkco ezimbini. Amagwegwe anye alula ukwenza kwaye kulula ukuwasebenzisa, kodwa amandla awalungile. Uninzi lwazo lusetyenziswa kwiindawo zokusebenza ezinomthamo wokuphakamisa ongaphantsi kweetoni ezingama-80; iigwegwe ezimbini ezine-symmetrical forces zihlala zisetyenziswa xa umthamo wokuphakamisa mkhulu.
Amagwegwe e-crane elayitiweyo ahlanjululwa kwiiplati ezininzi ezisikiweyo kunye nezakhiwe zentsimbi. Xa iipleyiti zodwa zineentanda, i-hook yonke ayiyi konakala. Ukhuseleko lulungile, kodwa ubunzima bokuzimela bukhulu.
Uninzi lwazo lusetyenziselwa ukuphakamisa umthamo omkhulu okanye ukuphakamisa iibhakethi zetsimbi ezityhidiweyo kwi-crane. I-hook idla ngokuchaphazeleka ngexesha lokusebenza kwaye kufuneka yenziwe ngentsimbi ye-carbon ephezulu kunye nobunzima obuhle.
Izikhonkwane ze-Crane eziveliswa yi-SEVENCRANE zenziwe ngokweemfuno zeemeko zobugcisa be-hook kunye neenkcukacha zokhuseleko. Iimveliso zinesatifikethi somgangatho wemveliso, esihlangabezana neemfuno zeemeko ezininzi.
Isixhobo se-crane hook senziwe nge-20 ephezulu ye-carbon steel okanye i-forged hook yezixhobo ezikhethekileyo ezifana ne-DG20Mn, DG34CrMo. Izinto eziphathekayo ze-plate hook zisetyenziswa ngokubanzi i-A3, i-C3 eqhelekileyo yentsimbi ye-carbon, okanye i-16Mn yentsimbi ephantsi ye-alloy. Zonke izikhonkwane ezintsha ziye zavavanywa umthwalo, kwaye ukuvulwa kwekhonkco akudluli i-0.25% yokuvula kokuqala.
Khangela i-hook yokuqhekeka okanye i-deformation, i-corrosion kunye nokugqoka, kwaye kuphela emva kokuphumelela zonke iimvavanyo zivumelekile ukuba zihambe kwi-factory. Amasebe abalulekileyo athenga amagwegwe afana nomzila kaloliwe, amazibuko, njl.
Iigwegwe ze-crane ezidlula uhlolo ziya kumakishwa kwindawo enoxinzelelo oluphantsi lwehuku, kubandakanya ubunzima obuphakanyisiweyo bokuphakamisa, igama lomzi-mveliso, uphawu lokuhlola, inombolo yemveliso, njl.
