I-crane hook iwuhlobo oluvame kakhulu lwesisakazeli emishinini yokuphakamisa. Ivamise ukulengiswa entanjeni yocingo yomshini wokufukula ngokusebenzisa amabhulokhi we-pulley kanye nezinye izakhi.
Izingwegwe zingahlukaniswa zibe izingwegwe ezilodwa kanye nezingwegwe ezimbili. Amahhuku angawodwa alula ukwenza futhi kulula ukuwasebenzisa, kodwa amandla awalungile. Iningi lazo lisetshenziswa ezindaweni zokusebenza ezinomthamo wokuphakamisa ongaphansi kwamathani angama-80; izingwegwe eziphindwe kabili ezinamandla okulinganisa zivame ukusetshenziswa lapho umthamo wokuphakamisa mkhulu.
Izingwegwe ze-crane ezine-laminated zikhishwa kusuka kumapuleti amaningi ensimbi asikiwe futhi akheke. Lapho amapuleti ngamanye anemifantu, yonke ingwegwe ngeke ilimale. Ukuphepha kuhle, kodwa isisindo sakho sikhulu.
Iningi lazo lisetshenziselwa ukuphakamisa umthamo omkhulu noma ukuphakamisa amabhakede ensimbi ancibilikisiwe ku-crane. Ihuku livame ukuba nomthelela ngesikhathi sokusebenza futhi kufanele lenziwe ngensimbi yekhabhoni esezingeni eliphezulu enokuqina okuhle.
Izingwegwe ze-Crane ezikhiqizwa yi-SEVENCRANE zenziwa ngokuya ngezidingo zezimo zobuchwepheshe be-hook kanye nokucaciswa kokuphepha. Imikhiqizo inesitifiketi sekhwalithi yokukhiqiza, esihlangabezana nezidingo zezimo eziningi.
I-crane hook material yenziwe nge-20 high quality carbon steel noma i-forged hook izinto ezikhethekile ezifana ne-DG20Mn, DG34CrMo. Impahla yehhuku yepuleti ngokuvamile isetshenziswa i-A3, i-C3 yensimbi ejwayelekile ye-carbon, noma i-16Mn low alloy steel. Zonke izingwegwe ezintsha ziye zahlolwa umthwalo, futhi ukuvulwa kwehhuku akudluli u-0.25% wokuvulwa kwasekuqaleni.
Hlola i-hook ngokuqhekeka noma ukuguqulwa, ukugqwala nokuguga, futhi ngemva kokudlula zonke izivivinyo zivunyelwe ukuphuma efektri. Iminyango ebalulekile ithenga izingwegwe ezifana nezitimela, izikebhe, njll. Amahhuku adinga ukuhlolwa okwengeziwe (ukutholwa kwamaphutha) lapho ephuma efekthri.
Izingwegwe ze-crane ezidlula ukuhlolwa zizomakwa endaweni enengcindezi ephansi yehuku, okuhlanganisa nesisindo sokuphakamisa esilinganiselwe, igama lemboni, uphawu lokuhlola, inombolo yokukhiqiza, njll.
