Shackleluhlobo lwendwayimane, olusetshenziswa kakhulu ezimbonini ezahlukahlukene njengamandla kagesi, insimbi, uphethiloli, imishini, ujantshi, imboni yamakhemikhali, itheku, izimayini, ukwakhiwa njalonjalo. Amaketanga ayafana nezinye izinsimbi. Banesethi yabo yokusetshenziswa nokucaciswa kokungasebenzi. Inothi lokusetshenziswa kwamaketanga: Amaketanga kufanele axhase umthwalo ngokufanele.
Lokho wukuthi, amandla okusebenza kufanele abe eceleni kwe-eksisi yomugqa ophakathi wesibopho ukuvimbela ukugoba nokuqina kwemithwalo, ingasaphathwa eyeqile. Ukusetshenziswa nokungasebenzi kwe-amaketanga should be rolled flexibly in the lifting hole, and no jamming is allowed. Phenomenon: The amaketanga body must not bear the effect of lateral bending moment, that is, the effect bearing capacity should be in the plane of the body.

Umkhawulo ubandakanya i-engeli phakathi kwemigqa emibili yemilenze ethwelwe yiamaketanga cannot be greater than 120 degrees. The use and invalidation of amaketangas The amaketanga is that when the wire rope sling is used as a binding sling, the horizontal pin part of the amaketanga should be connected with the keyhole of the wire rope sling. The appearance is when the rigging is lifted.

Ukungqubuzana phakathi kwentambo yocingo kanye neamaketanga causes the amaketanga to roll, and there is a risk of detachment. The use and invalidation specifications of the amaketanga. The pin is deformed up to 5% of the original size; the bolt is necrotic or slippery.
