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

EP-serien omfattar tv\u00e5 serier. BL-serien<\/strong> Kedjor f\u00f6ljer ANSI B29.8, den dominerande standarden i Nordamerika och Korea, och specificeras med en tv\u00e5siffrig kod som anger stiftens diameterklass och l\u00e4nkplattantal per l\u00e4nk (t.ex. betyder BL622 6\/8-tums stigning, 2x2 platts\u00f6mning). LH-serien<\/strong> Kedjorna f\u00f6ljer den europeiska beteckningen ISO 4347 och delar dimensionskompatibilitet med m\u00e5nga europeiska gaffeltruckstillverkares specifikationer. B\u00e5da serierna \u00e4r tillverkade av legerade st\u00e5lplattor och genomh\u00e4rdade stift, d\u00e4r varje kedja f\u00f6rtestades vid provbelastning innan den l\u00e4mnar produktionslinjen.<\/p>\n

Anv\u00e4ndningsomr\u00e5den str\u00e4cker sig bortom gaffeltruckar till industriella vertikala portmotvikter, kranlyftblock, sp\u00e4nnmekanismer p\u00e5 pressb\u00e4ddar och lastutj\u00e4mnande anordningar p\u00e5 fordonsmonteringsfixturer. F\u00f6r alla till\u00e4mpningar som kr\u00e4ver underh\u00e5llsbyte kan EP-kedjans modellnummer och stigning korsrefereras direkt till OEM-artikelnumret p\u00e5 beg\u00e4ran.<\/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

En l\u00f6vkedja kan dock inte \u00f6verf\u00f6ra rotationskraft genom ett kedjehjulsingrepp. Den anv\u00e4nds alltid \u00f6ver en vanlig cylindrisk trumma, en styrskiva eller en slitsad ankarstift. Den praktiska konsekvensen \u00e4r att l\u00f6vkedjor n\u00e4stan uteslutande f\u00f6rekommer i linj\u00e4ra lyft- och sp\u00e4nningsapplikationer, aldrig i roterande drivlinor.<\/p>\n<\/div>\n

Fem tillverkningsf\u00f6rdelar med EP-bladkedjor<\/h2>\n
\n
\n

100% Bevisbelastningstestning<\/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

Genomh\u00e4rdade legeringsstift<\/h3>\n

Alla EP-bladkedjestift \u00e4r genomh\u00e4rdade till HRC 48-52 med kontrollerad atmosf\u00e4rsv\u00e4rmebehandling. H\u00e5rdhetsprofilen verifieras p\u00e5 provstift fr\u00e5n varje v\u00e4rmebehandlingssats. Ett endast yth\u00e4rdat stift skulle fallera genom att b\u00f6jas i k\u00e4rnan under upprepade st\u00f6tbelastningar som \u00e4r typiska f\u00f6r gaffeltrucksdrift.<\/p>\n<\/div>\n

\n

Konsekventa toleranser f\u00f6r pl\u00e5tst\u00e4mpling<\/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

Sm\u00f6rjda stift vid montering<\/h3>\n

EP-bladkedjor monteras med ett penetrerande sm\u00f6rjmedel som appliceras p\u00e5 varje stift f\u00f6re pressning. Till skillnad fr\u00e5n rullkedjor har bladkedjor ingen inbyggd oljebeh\u00e5llare. Utan fabriksapplicerat sm\u00f6rjmedel i gr\u00e4nssnittet mellan stift och h\u00e5l b\u00f6rjar en ny kedja torr och genererar h\u00f6gt slitage fr\u00e5n f\u00f6rsta anv\u00e4ndningen. Fabrikssm\u00f6rjning minskar det initiala slitaget och \u00f6verbryggar gapet tills underh\u00e5llsprogrammet b\u00f6rjar.<\/p>\n<\/div>\n

\n

Anpassad l\u00e4ngd med \u00e4ndbeslag<\/h3>\n

EP-l\u00f6vkedjor levereras kapade till r\u00e4tt l\u00e4ngd med OEM-specificerade \u00e4ndbeslag, pressade, svetsade eller fastsp\u00e4nda. Vanliga beslag inkluderar g\u00e4ngade f\u00f6rankringsstift med sexkantsmuttrar, flikformade \u00e4ndplattor f\u00f6r trisssystem och gaffel\u00e4ndar f\u00f6r vagninf\u00e4stning. \u00c4ndbeslagens m\u00e5tt verifieras mot OEM-ritning eller prov innan varje best\u00e4llning kapas.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\n
\n

Gaffeltrucksmastaggregat<\/h3>\n

EP-BL- och EP-LH-kedjorna \u00e4r direkta OEM-kompatibla ers\u00e4ttningar f\u00f6r lyftkedjor f\u00f6r gaffeltruckar p\u00e5 Toyota-, Komatsu-, Linde-, Hyster-, Yale-, Mitsubishi-, Doosan-, BT- och Jungheinrich-truckar fr\u00e5n 0,5 ton till 25 ton. B\u00e5de frilyftskedjornas och huvudlyftskedjornas positioner t\u00e4cks. Kedjorna kapas till exakt mastlyfth\u00f6jd och monteras med l\u00e4mpligt ankare och gaffelf\u00e4ste.<\/p>\n<\/div>\n

\n

Industriella motviktssystem<\/h3>\n

Snabbg\u00e5ende industriella vertikalportar, maskinverktygspindelar och motviktsmekanismer f\u00f6r pressb\u00e4ddar anv\u00e4nder EP-LH1034 till EP-LH1644-kedjor som l\u00f6per \u00f6ver st\u00e5lskivor. Kedjan m\u00e5ste bibeh\u00e5lla dimensionsstabilitet under upprepade dragcykler utan krypning eller m\u00e4tbar f\u00f6rl\u00e4ngning. EP-kedjor testas med 10 miljoner cykler vid 30% brottbelastning utan n\u00e5gon m\u00e4tbar \u00f6kning av fogspel i typprovning f\u00f6re produktion.<\/p>\n<\/div>\n

\n

Lyft- och kranrullar<\/h3>\n

EP-LH2034 till EP-LH2066 tunga bladkedjor i 63,5 mm stigning anv\u00e4nds i lyftblock f\u00f6r traverskranar, portalkedjor f\u00f6r skeppsvarv och upph\u00e4ngningssystem f\u00f6r gruvburar. Brottlaster \u00f6ver 800 kN p\u00e5 en enda kedjetr\u00e5d g\u00f6r dessa till de mest kapacitetsstarka komponenterna i Korea Ever-Power-serien. Flertr\u00e5diga inrullningsupps\u00e4ttningar med tv\u00e5 eller fyra parallella kedjor \u00e4r standard f\u00f6r lyftkapaciteter \u00f6ver 30 ton.<\/p>\n<\/div>\n

\n

Fixturer f\u00f6r monteringslinjer f\u00f6r fordon<\/h3>\n

Karosserib\u00e4rare i vitt, pallar f\u00f6r drivlinemontering och precisionsfixturer f\u00f6r vertikal justering p\u00e5 bilmonteringslinjer anv\u00e4nder bladkedjor eftersom den h\u00f6ga lastkapaciteten i en smal sektion g\u00f6r att fixturen kan b\u00e4ra fordonskarosspaneler eller motorblock utan att kedjan sticker ut utanf\u00f6r fixturens gr\u00e4ns. EP-BL644 och EP-BL646 \u00e4r vanliga i dessa applikationer.<\/p>\n<\/div>\n<\/div>\n

\n

Riktlinjer f\u00f6r inspektion och utbyte av bladkedjor<\/h2>\n

Fel p\u00e5 bladkedjor i en gaffeltruck \u00e4r en allvarlig s\u00e4kerhetsrisk. F\u00f6ljande riktlinjer \u00e5terspeglar inspektionskraven enligt ISO 4347 och FEM 4.004 och b\u00f6r utg\u00f6ra grunden f\u00f6r ett regelbundet underh\u00e5llsprogram.<\/p>\n

\n
\n

En<\/p>\n

Kontrollera kedjef\u00f6rl\u00e4ngningen<\/h4>\n

M\u00e4t 12 eller 25 l\u00e4nkar vid arbetssp\u00e4nning. Byt ut n\u00e4r f\u00f6rl\u00e4ngningen \u00f6verstiger 3% av den nominella l\u00e4ngden. F\u00f6r BL622 med 19,05 mm stigning \u00e4r 25 l\u00e4nkars nominella l\u00e4ngd 476,25 mm; byt ut vid 490,5 mm eller mer.<\/p>\n<\/div>\n

\n

B<\/p>\n

Kontrollera om det finns spruckna plattor<\/h4>\n

Reng\u00f6r kedjan med ett avfettningsmedel och inspektera varje l\u00e4nkplatta f\u00f6r ytliga sprickor, s\u00e4rskilt n\u00e4ra h\u00e5len f\u00f6r stiften och i plattans mitt. En sprucken platta \u00e4r omedelbart orsak till byte oavsett f\u00f6rl\u00e4ngning.<\/p>\n<\/div>\n

\n

C<\/p>\n

Kontrollera stiftrotation<\/h4>\n

Markera stiftens \u00e4ndar och kontrollera att de inte har roterat i de yttre plattorna under drift. Binnets rotation inneb\u00e4r att presspassningen har g\u00e5tt s\u00f6nder; kedjan m\u00e5ste bytas ut omedelbart. Roterande stiften genererar snabbt plattslitage och kan leda till pl\u00f6tsligt haveri.<\/p>\n<\/div>\n

\n

D<\/p>\n

Sm\u00f6rj vid varje service<\/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.

Vanliga fr\u00e5gor<\/h2>\n
\n
\nHur identifierar jag r\u00e4tt bladkedja till min gaffeltruck?<\/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
\nVilken \u00e4r den rekommenderade s\u00e4kerhetsfaktorn f\u00f6r en bladkedja p\u00e5 en gaffeltruck?<\/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
\nHur ofta b\u00f6r gaffeltrucksbladkedjor bytas ut?<\/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
\nKan en l\u00f6vkedja repareras genom att byta ut enskilda l\u00e4nkar?<\/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

“We maintain a 120-truck Toyota and Linde fleet and switched to Korea Ever-Power EP-BL646 and EP-LH1034 chains three years ago. Elongation at the 6,000-hour mark averaged 1.8%, below our 3% threshold. We extended the replacement interval from 4,000 to 6,000 hours, which cut chain costs significantly.”<\/p>\n
