Pehea e ʻike ai i ka Aluminum Alloy Lever Hoist

Hiki iā ʻoe ke kuhikuhi i nā ʻōlelo aʻe:

1) Nānā kiʻi:

H. Pono e hana maikaʻi ʻia nā ʻāpana a pau o ka ipu, me ka ʻole o nā ʻōpala, nā ʻōpala a me nā hemahema ʻē aʻe e pili ana i ka maikaʻi o ka helehelena.

B. Ke kūlana o ke kaulahao hāpai o ka lever hoist 3 tona.
E kāpae ʻia kēia mau mea:
(1) degere o ka corrosion: ʻo ka ʻili o ke kaulahao ua pitted corrosion a i ʻole flake off.
(2) ʻoi aku ka nui o ka ʻaʻahu o ke kaulahao ma mua o 10% o ke anawaena nominal;
(3) deformation, māwae a me waho pōʻino;
(4) Hoʻololi ka lōʻihi o ka pitch ma luna o 3%.

C. Kūlana Hook.
E kāpae ʻia kēia mau mea:
(1) Deformation a i ʻole ka nalowale ʻana o ka pine palekana o ka makau;
(2) ʻAʻole hiki ke hoʻololi manuahi ke apo o ka makau (360° rotation);(3) ʻOi aku ka nui o ka hook (ʻoi aku ma mua o 10%) a me ka deformation makau (ʻoi aku ma mua o 15% ka nui o ka nui), torsion (ʻoi aku ma mua o 10°), nā māwae, nā kihi acute, corrosion, a me ka warping.

D. E ho'olako 'ia ka lima lever hoist me kahi kaulahao kūpono e kōkua ai i ka ho'okomo pono 'ana i ke kaulahao a me ka sprocket, a e hō'oia i ka hā'ule 'ole o ke kaulahao mai ke apo apo sprocket i ka manawa e kau 'ia ai ka lever hoist a hoonaueue ma ka makemake.
2) Nā ʻano hoʻāʻo:

A. Static load test: i ka ho'āʻo hoʻokau paʻa, huki i ka lima a hoʻohuli i ka maiuu hoʻohuli, i ʻoi aku ka hoʻopaʻa ʻana i luna a i lalo i kēlā me kēia, e hana maʻalahi kēlā me kēia mīkini, me ka ʻole o ka hoʻopaʻa ʻana a i ʻole ka wehe a paʻa.E hoʻokaʻawale i ka mea paʻa, e huki i ke kaulahao ma ka lima e māmā a maʻalahi.

B.Dynamic load test: ma 1.5 mau manawa hoʻouka hoʻāʻo, pono e hoʻokō i nā koi aʻe:

(1) Lifting chain and sprocket, moku holo moku, lima huki kaulahao a me ka lima sprocket meshing pono;
(2) Pono e maʻalahi ka hoʻoili ʻana o ke kaʻa a me ka ʻole o nā ʻano ʻano like ʻole;
(3) ʻAʻohe torsion a kink hanana o ke kaulahao hāpai i ke kaʻina o ka hāpai ʻana a me ka iho ʻana;
(4) Paʻa ka lima, a ʻaʻohe loli nui o ka huki lima;
(5) Hiki ke hilinaʻi i ka hana hoʻomaha.
Manaʻo wau he mea kōkua ia iā ʻoe.

Inā makemake ʻoe, pls e ʻoluʻolu e hoʻokaʻaʻike me kā mākou hui.
