Ka kakaretso ena, re manolla lintlha tsa tekheniki tse bontšang hore na letjeketjane le ka phahamisa bokae, karolo ea lintlha tsa polokeho, le lintlha tsa bokhoni tse sebetsang litlhophisong tse fapaneng tsa hitch.

1. Ke Eng e Hlalosang Bokhoni ba Moroalo oa Round Sling?

Matla a letjeketjane ha a na boikhethelo—ke phello ea mabaka a 'maloa a sebetsang hammoho.

1.1 Theko e Jarang Meroalo

Bohareng ba letjeketjane le leng le le leng ho na le motheo o jereng moroalo —khoele e tsoelang pele ea khoele ea maiketsetso e tiileng haholo, eo hangata e leng polyester (PES) kapa polyamide (PA). Palo ea likhoele, botenya ba tsona, le tlhophiso ea tsona li etsa qeto ea letjeketjane matla a ho robeha ha , ka lebaka leo, moeli oa mosebetsi oa eona (WLL) .

Ho ea ka EN 1492-2 , tekanyetso ea Europe ea li-slings tse pota-potileng tse entsoeng ka likhoele tse entsoeng ke motho, mokokotlo o sirelelitsoe ka letsoho le nang le mekhahlelo e 'meli e sa jareng mojaro empa e fana ka tšireletso khahlanong le tšenyo ea mechine, mahlaseli a UV le abrasion. Sekoahelo se boetse se na le li-coding tsa mebala le leibole ea boitsebahatso.

1.2 Ntlha ea Tšireletseho: 7:1

Kamano pakeng tsa matla a ho senya le WLL e hlalosoa ke ntlha ea tšireletso . Ho latela EN 1492-2 , likhoele tse chitja li tlameha ho ba le ntlha ea polokeho ea 7: 1 . Hona ho bolela:

• Lejoe le nang le WLL ea tone e le 1 le na le boima bo fokolang ba ho robeha ba lithane tse 7

• Lejoe le nang le WLL ea lithane tse 10 le na le boima bo fokolang ba ho robeha ba lithane tse 70

• Lejoe le nang le WLL ea lithane tse 100 le na le boima bo fokolang ba ho robeha ba lithane tse 700.

Ntho ena ea 7: 1 e fana ka tekanyo ea bohlokoa ea tšireletso bakeng sa maemo a sebele a lefats'e-ho roala ho tsosoa, ho roala, ho senyeha ha tikoloho, le lintho tse ling tse sa lebelloang tse ka fokotsang matla a sling ka nako.

1.3 Khoutu ea Mebala le Boitsebiso ba Bokhoni

EN 1492-2 e laela sistimi e nang le mebala bakeng sa li-slings tse chitja, e lumellang ho tsebahatsa bokhoni bo potlakileng sebakeng sa mosebetsi. Kamano e tloaelehileng ea 'mala-WLL ke:

Mohloli: Tekanyetso ea kh'outu ea mebala ea EN 1492-2

Bakeng sa matla a holimo ho feta lithane tse 10, khoutu ea mebala e tsoela pele ka mebala e eketsehileng le matšoao, hangata ka WLL e hatisitsoeng ka ho toba leiboleng.

2. The Capacity Spectrum: Ho tloha ho 0.5 Tons ho ea ho 500 Tons

Li-slings tse pota-potileng li etsoa ka mefuta e mengata ea bokhoni, e 'ngoe le e' ngoe e etselitsoe lisebelisoa tse khethehileng.

2.1 Bokhoni ba Leseli: 0.5 ho 5 Tons

Karolong e ka tlase ea sekhahla, likhoele tse chitja ho tloha ho lithane tse 0.5 ho isa ho tse 5 li sebelisoa ho:

• Ts'ebetso ea polokelo ea thepa le thepa - ho phahamisa liphalete, mabokose, le thepa e pakiloeng

• Ho hlahisa leseli - likarolo tse tsamaeang, li-sub-assemblies, le lihlahisoa tse felileng

• HVAC le ho kenya motlakase - lisebelisoa tsa ho beha maemo le likarolo tse boima

• Ho hlokomela le ho lokisa —ho phahamisa liinjini, lipompo le likarolo tsa mechine

Li-slings tsena hangata li bobebe, li tenyetseha haholo, 'me ho bonolo ho li tšoara. Li fumaneha ka li-diameter tse nyane le bolelele bo bokhutšoane, ka mebala ea mebala ho tloha ho pherese (tone e le 'ngoe) ho ea ho khubelu (lithane tse 5).

2.2 Bophahamo bo Bohareng: Lithane tse 5 ho isa ho tse 50

Li-slings tse chitja tse nang le matla a mahareng (lithane tse 5 ho isa ho tse 50) ke lipere tsa:

• Kaho —maballo a tšepe a phahamisang, liphanele tsa konkreite le meaho e seng e entsoe

• Ho etsa lintho tse boima - ho sebetsana le lirafshoa tse kholo, tse forging le likarolo tse entsoeng ka mochini

• Ho haha ​​le ho lokisa likepe —ho beha likarolo tsa likepe, lienjene le thepa

• Merero ea meralo ea motheo —marokho, lithanele, le boenjiniere bo boholo ba sechaba

Li-slings tsena li fumaneha ka li-diameter tse kholoanyane, tse nang le matsoho a mabeli bakeng sa tšireletso e eketsehileng. Likhoutu tsa mebala li tloha ho bofubelu (lithane tse 5) ho ea ho sootho (lithane tse 6), boputsoa (lithane tse 8), le lamunu (lithane tse 10 ho ea holimo).

2.3 Bokhoni bo boima: Lithane tse 50 ho isa ho tse 500

Boemong bo phahameng ka ho fetisisa ba sebono, lithane tse 50 ho isa ho tse 500 ho: ho sebelisoa likhoele tse chitja ho tloha ho

• Boenjineri ba kantle ho leoatle le ba leoatleng - ho phahamisa li-module tsa leoatle, sethala le lisebelisoa tse boima

• Ho fehla motlakase —ho sebetsana le li-turbine, lijenereithara le li-transformer

• Kaho e boima ea liindasteri —ho haha ​​mehaho e meholo ea tšepe le likepe tsa khatello

• Mesebetsi ea sebaka sa likepe —ho phahamisa likarolo tsohle tsa likepe le mechine e boima

Li-slings tsena li entsoe ka likhoele tse ngata tsa mantlha, matsoho a boima, le litlhophiso tsa tloaelo. Hangata li etsoa ho odara, ka tlhahlobo e matla le setifikeiti.

Lintlha tsa laboratori tsa Lishenflex li bonts'a hore kamano pakeng tsa palo ea khoele ea mantlha le bokhoni e latela sekhahla se ka lebelloang-bokhoni bo eketseha ka mokhoa o lekanang le palo ea likhoele tse jarang moroalo, ha sleeve e fana ka tšireletso e tsitsitseng ho pholletsa le mefuta eohle ea matla.

4. Maemo le Teko

Li-slings tse pota-potileng li laoloa ke litekanyetso tse 'maloa tsa machaba tse hlalosang bokhoni, polokeho le litlhoko tsa tlhahlobo.

4.1 EN 1492-2

EN 1492-2 ke tekanyetso ea Europe ea likhoele tse chitja tse entsoeng ka likhoele tse entsoeng ke motho. E totobatsa:

• Litlhoko tsa lintho tse bonahalang (polyester, polyamide, polypropylene)

• Ntlha ea polokeho ea 7:1

• Litlhoko tsa ho ngola mebala le ho ngola lileibole

• Mekhoa ea tlhahlobo le setifikeiti

4.2 AS 4497:2018

AS 4497:2018 ke tekanyetso ea Australia ea li-synthetic fiber round slings. E totobatsa ntlha ea polokeho ea 7: 1 bakeng sa li-slings tse pota-potileng polyester mme e fana ka litlhoko tse qaqileng bakeng sa tlhahlobo, tlhahlobo le mekhoa ea ho tlohela mosebetsi.

4.3 Teko le Ho fana ka Setifikeiti

Li-slings tse pota-potileng li kentsoe bopaki ho makhetlo a 2 WLL ea tsona pele li kenngoa ts'ebetsong, ho latela EN 1492-2 le AS 4497:2018. Teko ena e netefatsang boima ba 'mele e netefatsa bots'epehi ba letjeketjane 'me e etsa bonnete ba hore e khona ho sebetsana le boemo ba eona ka mokhoa o sireletsehileng.

Li-slings tse nang le matla a holimo (lithane tse 50 ho ea holimo) hangata li lekoa ka mokhoa o senyang ho netefatsa ntlha ea polokeho ea 7:1. Liteko tsena li tiisa hore matla a ho robeha a letjeketjane a kopana kapa a feta bonyane bo hlokahalang.

5. Kakaretso le Likhothaletso tse Sebetsang

Bokhoni ba thepa e pota-potiloeng ke letjeketjane bo akaretsa mefuta e mengata haholo - ho tloha ho lithane tse 0.5 ho isa ho tse 500 - ka lebaka la ho feto-fetoha ha kaho ea fiber ea maiketsetso le moeli oa polokeho o fanoeng ke ntlha ea 7: 1. Ho utloisisa hore na bokhoni bo lekantsoe joang, hore na litlhophiso tsa hitch li ama meeli ea mojaro joang, le hore na ke litekanyetso life tse sebetsang ke tsa bohlokoa bakeng sa ts'ebetso e sireletsehileng ea ho phahamisa.

Lintlha tsa bohlokoa:

1. Bokhoni bo khethoa ke palo ea likhoele tsa mantlha le kaho - likhoele tse ngata li bolela WLL e phahameng

2. Tšireletso ea 7:1 e fana ka moeli oa bohlokoa - letjeketjane la 1 tonne le na le matla a ho robeha a lithane tse 7.

3. Likhoutu tsa mebala li thusa ho tsebahatsa kapele - pherese (1t) ho ea ho lamunu (10t+)

4. Ho hlophisoa ha li-hitch ho ama bokhoni - li-hitch hitch li fokotsa WLL ka 20%, libaskete li e eketsa

5. Maemo a netefatsa boleng le polokeho - EN 1492-2 le AS 4497: 2018 e totobatsa litlhoko

6. Teko ea bopaki e netefatsa botšepehi - li-slings li kentsoe bopaki ho makhetlo a 2 WLL ea tsona pele ho ts'ebeletso.

Lishenflex e etsa li-slings tsa polyester rounds ho litekanyetso tsa EN 1492-2 le AS 4497: 2018, tse fumanehang ka matla ho tloha ho lithane tse 0.5 ho isa ho tse 500, tse nang le matšoao a mebala-bala le ntlha ea tšireletso ea 7: 1. Lihlahisoa tsa rona li lekoa ebile li netefalitsoe bakeng sa ts'ebetso e tšepahalang lits'ebetsong tsohle tsa ho phahamisa.
