Ua ntej: Xaiv ib txoj hlua raws li lub tswv yim
Hlau hlua slings yog tsim los ntawm cov txheej txheem steel hlau hlua. Lawv feem ntau suav nrog phosphate-coated steel hlau hlua, galvanized steel hlau hlua, thiab du -coated steel hlau hlua. Lawv yog siv rau lifting, rub, tensioning, thiab nqa loads. Lawv muaj lub zog siab, lub teeb yuag, kev ua haujlwm ruaj khov, thiab tsis kam mus rau tam sim ntawd tawg. Lawv tau siv dav hauv kev lag luam xws li hlau, tshuaj, tsheb thauj mus los, thiab chaw nres nkoj.
Chain slings yog ua los ntawm cov hlau txuas txuas. Lawv feem ntau welded los yog sib sau ua ke, thiab tuaj yeem tsim ua ib qho los yog ntau qhov txuas. Ua los ntawm siab - zoo alloy steel, lawv paub txog lawv cov hnav tsis kam, kub tsis kam, tsis muaj ductility, thiab tsis kam mus rau stretching nyob rau hauv load. Lawv muab lub neej ua haujlwm ntev thiab hloov tau yooj yim, ua rau lawv haum rau loj - nplai, nquag siv. Slexible, multi-legged slings thiab ntau yam kev sib txuas ua kom zoo dua qub thiab txo cov nqi.
Ib qho ua tiav sling rigging teeb muaj ib lub nplhaib tseem ceeb, ib qho txuas shackle, ib txoj hlua, thiab cov khoom siv hlau kawg. Lub ntsiab sling nplhaib muaj xws li ntev, puag ncig, thiab ua ke sling rings. Cov kev sib txuas shackles muaj xws li hneev shackles thiab chain shackles. Lub sling muaj xws li flats thiab round slings. Cov khoom siv hlau kawg suav nrog ntau yam hooks thiab lwm yam khoom siv hlau. Lub sling rigging teeb no tuaj yeem ua kom zoo dua kom tau raws li cov neeg siv khoom xav tau.
Thib ob: Xav txog cov kev xav hauv qab no thaum xaiv cov hlua.
Lus Cim rau cov hlua hlua khi: Rau ib qho - ceg slings, qhov txuas txuas yuav tsum nyob rau hauv vertically thiab ncaj nraim saum nruab nrab ntawm lub ntiajteb txawj nqus ntawm lub load.
Rau ob- ceg rigging, hooks yuav tsum nyob rau ntawm ob sab ntawm lub load, nrog rau cov hooks nyob rau saum toj ntawm lub load qhov chaw ntawm lub ntiajteb txawj nqus.
Rau peb- lossis plaub- ceg rigging, cov hooks yuav tsum sib npaug ntawm qhov chaw nyob ib puag ncig lub nra, nrog cov hooks tso ncaj qha rau saum lub load qhov nruab nrab ntawm lub ntiajteb txawj nqus. Thaum siv sling rigging system, thov nco ntsoov qhov kev sib raug zoo ntawm lub kaum sab xis thiab lub peev xwm thauj khoom. Yog tias cov hlua uas siv hauv cov txheej txheem rigging puas lawm, tsis txhob siv lawv kom tsis txhob muaj kev cuam tshuam lossis kev vibration ntawm lub load.
