Leaf Chain and Hoisting Chain – Product Overview<\/h2>\n
\n
\n

EP valikusse kuulub kaks seeriat. BL-seeria<\/strong> Ketid j\u00e4rgivad ANSI B29.8 standardit, mis on P\u00f5hja-Ameerikas ja Koreas domineeriv standard, ning neid t\u00e4histatakse kahekohalise koodiga, mis n\u00e4itab tihvti l\u00e4bim\u00f5\u00f5du klassi ja l\u00fcliplaatide arvu l\u00fcli kohta (nt BL622 t\u00e4hendab 6\/8-tollist sammu, 2x2 plaatide paeltega kinnitust). LH-seeria<\/strong> Ketid vastavad ISO 4347 Euroopa standardile ja neil on m\u00f5\u00f5tmetega \u00fchilduvus paljude Euroopa kahvelt\u00f5stukite originaalvaruosade tootjate spetsifikatsioonidega. M\u00f5lemad seeriad on valmistatud legeerterasest plaatidest ja l\u00e4bikarastatud tihvtidest ning iga kett on enne tootmisliinilt lahkumist eelnevalt koormuse all testitud.<\/p>\n

Rakendused ulatuvad lisaks kahvelt\u00f5stukitele ka t\u00f6\u00f6stuslike vertikaalsete uste vastukaaludeni, kraana t\u00f5steplokkideni, pressaluste pingutusmehhanismideni ja autode montaa\u017eiseadmete koorma tasandusseadmeteni. Iga rakenduse puhul, mis vajab hooldusvahetust, saab EP-keti mudelinumbri ja sammu soovi korral otse originaalvaruosa numbriga siduda.<\/p>\n<\/div>\n

Leaf Chain vs Roller Chain – Key Differences<\/h3>\n
\n
\n

A leaf chain is purely a tension member. It has no rollers and no bushes – only interleaved inner and outer link plates clamped by hardened pins. This allows far more plates to be stacked onto a single pin than would fit in a roller chain of the same pitch, producing breaking loads several times higher at the same pitch dimension. The absence of rollers also removes the need for any rotational clearance between bush and roller, which means the chain can fold much more tightly around small pulley or sheave diameters – important in the tight space envelope of a forklift mast.<\/p>\n

Lehtkett ei saa aga p\u00f6\u00f6rlemisj\u00f5udu edastada ketiratta hammaste haarde kaudu. Seda kasutatakse alati tavalise silindrilise trumli, juhtratta v\u00f5i soonega ankrutihvti peal. Praktiline tulemus on see, et lehtkette kasutatakse peaaegu eranditult lineaarsetes t\u00f5ste- ja pingutusrakendustes, mitte kunagi p\u00f6\u00f6rlevates j\u00f5u\u00fclekannetes.<\/p>\n<\/div>\n

EP-lehtkettide viis tootmise eelist<\/h2>\n
\n
\n

100% koormustestimise t\u00f5end<\/h3>\n

Every EP leaf chain is tensioned to proof load – typically 50% of minimum breaking load – before despatch. Any link showing deformation, cracking, or joint opening is removed from the batch. This is not sampling: it is a 100% test on every chain supplied.<\/p>\n<\/div>\n

\n

L\u00e4bikarastatud sulamist tihvtid<\/h3>\n

K\u00f5ik EP-lehtketi tihvtid on kontrollitud atmosf\u00e4\u00e4ris kuumt\u00f6\u00f6tluse abil l\u00e4bi karastatud HRC 48\u201352-ni. K\u00f5vadusprofiili kontrollitakse iga kuumt\u00f6\u00f6tluspartii n\u00e4idistihvtide p\u00f5hjal. Ainult pinnakarastatud tihvt puruneks s\u00fcdamikust painutamise t\u00f5ttu korduvate l\u00f6\u00f6kkoormuste all, mis on t\u00fc\u00fcpilised kahvelt\u00f5stuki kasutamisel.<\/p>\n<\/div>\n

\n

J\u00e4rjepidevad plaadistantsimise tolerantsid<\/h3>\n

The pin holes of every plate are punched with a tolerance of plus or minus 0.01 mm. Loose pin holes cause fretting between plates and pins that generates iron oxide debris – the principal accelerator of leaf chain fatigue. Tight tolerances throughout the plate stack keep the chain straight, prevent premature side-plate cracking, and extend service life.<\/p>\n<\/div>\n

\n

M\u00e4\u00e4ritud tihvtid montaa\u017eil<\/h3>\n

EP-lehtketid monteeritakse enne pressimist igale tihvtile imbumisv\u00f5imelist m\u00e4\u00e4rdeainet kandes. Erinevalt rullkettidest pole lehtkettidel sisseehitatud \u00f5limahutit. Ilma tehases peale kantud m\u00e4\u00e4rdeaineta tihvti ja augu vahelises liideses alustab uus kett kuivalt ja tekitab esimesel kasutuskorral suure kulumise. Tehase m\u00e4\u00e4rimine v\u00e4hendab esialgset kulumiskiirust ja sillutab t\u00fchimiku kuni hooldusprogrammi alguseni.<\/p>\n<\/div>\n

\n

Kohandatud pikkus koos otsakinnitustega<\/h3>\n

EP-lehtketid tarnitakse pikkusesse l\u00f5igatuna, koos OEM-spetsifikatsioonidega pressitud, keevitatud v\u00f5i n\u00f6\u00f6pn\u00f5eltega kinnitatud otsaliitmikega. Levinud liitmike hulka kuuluvad keermestatud ankurdustihvtid kuuskantmutritega, otsaplaadid rihmarattas\u00fcsteemidele ja kahvliga otsad kelgu kinnitamiseks. Otsliitmike m\u00f5\u00f5tmed kontrollitakse enne iga tellimuse l\u00f5ikamist OEM-joonise v\u00f5i n\u00e4idise suhtes.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Kaetud on nii vabat\u00f5ste- kui ka peat\u00f5steketi positsioonid. Ketid l\u00f5igatakse t\u00e4pse masti t\u00f5stek\u00f5rguse j\u00e4rgi ning varustatakse sobivate ankru- ja kahvlikinnitustega.<\/p>\n<\/div>\n

\n

T\u00f6\u00f6stuslikud vastukaalus\u00fcsteemid<\/h3>\n

Kiirete t\u00f6\u00f6stuslike vertikaalsete uste, t\u00f6\u00f6pinkide tihvtide ja pressvoodi vastukaalumehhanismide puhul kasutatakse terasratastel liikuvaid kette EP-LH1034 kuni EP-LH1644. Kett peab s\u00e4ilitama m\u00f5\u00f5tmete stabiilsuse korduvate t\u00f5mbets\u00fcklite korral ilma roomamise v\u00f5i m\u00f5\u00f5detava pikenemiseta. EP-kette testitakse 10 miljoni ts\u00fckliga 30% purunemiskoormusel ilma m\u00f5\u00f5detava vuukide l\u00f5tku suurenemiseta tootmiseelsetes t\u00fc\u00fcbikatsetustes.<\/p>\n<\/div>\n

\n

T\u00f5stuki ja kraana rihveldamine<\/h3>\n

EP-LH2034 kuni EP-LH2066 j\u00e4melehtkette sammuga 63,5 mm kasutatakse kraanade t\u00f5steplokkides, laevatehase portaalkettides ja kaevanduspuuride riputuss\u00fcsteemides. \u00dcle 800 kN purunemiskoormus \u00fchel ketil teeb neist Korea Ever-Poweri tootesarja suurima kandev\u00f5imega pingutuskomponendid. Mitmekiulised k\u00f6ies\u00fcsteemid, mis kasutavad paralleelselt kahte v\u00f5i nelja ketti, on standardvarustuses t\u00f5stev\u00f5imega \u00fcle 30 tonni.<\/p>\n<\/div>\n

Autot\u00f6\u00f6stuse konveieri inventar<\/h3>\n

Kereraamide kandjad, j\u00f5u\u00fclekande montaa\u017eikaubad ja autode montaa\u017eiliinide t\u00e4ppis-vertikaalsed reguleerimisseadmed kasutavad lehtkette, kuna kitsa sektsiooni suur kandev\u00f5ime v\u00f5imaldab seadmel kanda s\u00f5iduki kereteid v\u00f5i mootoriplokke ilma, et kett ulatuks seadme piiridest v\u00e4lja. EP-BL644 ja EP-BL646 on nendes rakendustes tavalised.<\/p>\n<\/div>\n<\/div>\n

\n

Lehtketi kontrollimise ja vahetamise juhised<\/h2>\n

Kahvelt\u00f5stuki ketilehe rike on t\u00f5sine ohutusrisk. J\u00e4rgmised juhised kajastavad ISO 4347 ja FEM 4.004 kontrollin\u00f5udeid ning peaksid olema regulaarse hooldusprogrammi aluseks.<\/p>\n

\n
\n

A<\/p>\n

Kontrollige keti pikenemist<\/h4>\n

M\u00f5\u00f5tke t\u00f6\u00f6pingel 12 v\u00f5i 25 l\u00fcli. Vahetage v\u00e4lja, kui pikenemine \u00fcletab nimipikkuse 3%. BL622 puhul sammuga 19,05 mm on 25 l\u00fcli nimipikkus 476,25 mm; vahetage v\u00e4lja pikkusel 490,5 mm v\u00f5i rohkem.<\/p>\n<\/div>\n

\n

B<\/p>\n

Kontrollige pragunenud plaate<\/h4>\n

Puhastage kett rasvaeemaldusvahendiga ja kontrollige iga l\u00fcliplaati pinnapragude suhtes, eriti tihvtide aukude l\u00e4hedal ja plaadi alumises osas. Iga pragunenud plaat tuleb kohe v\u00e4lja vahetada, olenemata pikenemisest.<\/p>\n<\/div>\n

\n

C<\/p>\n

Kontrollige tihvti p\u00f6\u00f6rlemist<\/h4>\n

Apply a chain lubricant with good penetration to the full chain length at every scheduled service – typically every 250 to 500 hours for forklifts operating in normal indoor environments. Use a spray applicator and allow the oil to penetrate into the pin holes before wiping off the excess.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

\nKuidas ma tuvastan oma kahvelt\u00f5stukile sobiva lehtterati?<\/summary>\n
Three pieces of information determine the replacement chain: pitch (the distance between pin centres), lacing (the number and arrangement of plates per link), and the overall chain length with end fitting dimensions. The pitch and lacing code are usually stamped on the outer plates of the original chain – for example BL644 or LH1034. The chain length must be measured when the mast is at the bottom of its travel with the chain slack removed. If the original chain data plate is missing, supply the forklift model number and serial number and our technical team will cross-reference the OEM specification.<\/div>\n<\/details>\n
\nMilline on kahvelt\u00f5stuki lehtketi soovitatav ohutustegur?<\/summary>\n
ISO 4347 and ANSI B29.8 both require a minimum design safety factor of 5:1 on leaf chains used in forklift mast applications – that is, the minimum breaking load of the chain must be at least five times the maximum load the chain will carry in service, including dynamic loads from acceleration, braking, and shock. In practice, most forklift OEMs design to a 5:1 or 6:1 factor. Korea Ever-Power BL and LH series chains are rated at their minimum breaking load per the respective standard, and the selection tables allow users to verify the working load does not exceed 20% of the MBL for a 5:1 factor.<\/div>\n<\/details>\n
\nKui tihti tuleks kahvelt\u00f5stuki ketilehte vahetada?<\/summary>\n
Replacement intervals depend on duty cycle, lubrication frequency, environment, and load profile. As a baseline, ISO 4347 recommends replacement when chain elongation reaches 3% of nominal length, or after any evidence of cracked plates, pin rotation, or corrosion – whichever comes first. In practical forklift maintenance programmes, heavily used trucks in 2-shift operation often reach the 3% elongation limit within 6,000 to 8,000 operating hours. Lightly used trucks may run 15,000 to 20,000 hours. Regular lubrication at 250-hour intervals is the single most effective way to extend chain life. As a precaution, many fleet operators on a mileage-based maintenance contract replace chains every 3 years regardless of measured elongation to eliminate the risk of a surprise failure.<\/div>\n<\/details>\n
\nKas lehikett saab parandada \u00fcksikute l\u00fclide asendamise teel?<\/summary>\n
No. ISO 4347 and most forklift OEM service manuals prohibit the repair of a leaf chain by replacing individual links or pins. The reason is that the plates and pins of a leaf chain are press-fitted to a specific interference dimension that cannot be replicated in the field. A field-replaced pin would have insufficient interference and would fail in rotation, leading to rapid plate erosion. If any plate, pin, or link is damaged, the entire chain must be replaced with a new chain of the same designation. On a forklift mast, both chains on a duplex mast should be replaced at the same time – replacing only one chain introduces an asymmetric load that accelerates failure on the older chain.<\/div>\n<\/details>\n
