Heavy Duty Cranked-Link Chain – Product Overview<\/h2>\n
\n
\n

Toujours-Puissance cha\u00eenes de transmission \u00e0 maillons coud\u00e9s renforc\u00e9s<\/a> are a specialised family of roller chains designed for high-load, low-speed power transmission applications in heavy industrial equipment. The cranked-link design – also known as the offset-link or bent-link construction – uses link plates that are bent or cranked outward at the pin hole position rather than the conventional flat plate. This geometry allows the use of a larger-diameter pin and bush at the same pitch compared to a standard flat plate chain, resulting in a higher joint bearing area and significantly greater resistance to pin bending failure under the very high tensions encountered in these applications.<\/p>\n

La construction \u00e0 maillons coud\u00e9s pr\u00e9sente \u00e9galement un avantage pratique important\u00a0: les plaques int\u00e9rieure et ext\u00e9rieure ayant le m\u00eame profil coud\u00e9, contrairement aux deux profils plats diff\u00e9rents, la cha\u00eene peut \u00eatre mont\u00e9e et d\u00e9mont\u00e9e \u00e0 l\u2019aide de maillons de raccordement standard identiques aux maillons de roulement. Ceci simplifie la maintenance sur le terrain et r\u00e9duit le risque d\u2019erreur de montage. Le maillon de raccordement standard des cha\u00eenes \u00e0 rouleaux (\u00e0 ressort ou \u00e0 goupille fendue) utilise une plaque diff\u00e9rente de la plaque int\u00e9rieure de roulement, ce qui peut engendrer des probl\u00e8mes en cas d\u2019utilisation d\u2019un maillon inadapt\u00e9. Les cha\u00eenes \u00e0 maillons coud\u00e9s \u00e9liminent totalement ce probl\u00e8me.<\/p>\n

La gamme de biellettes coud\u00e9es EP couvre quatre s\u00e9ries principales. S\u00e9rie MXS<\/strong> (EP-MXS432, EP-MXS882, EP-MXS882F1, EP-MXS3011F1) couvrent les applications de liaison coud\u00e9e l\u00e9g\u00e8res \u00e0 moyennes avec un pas de 42 \u00e0 78 mm.

S\u00e9rie 2512<\/strong> (EP-2512, EP-2512F2, EP-2512F3, EP-2512F4) couvre les applications de transmission les plus exigeantes pour chariots \u00e9l\u00e9vateurs et v\u00e9hicules lourds, avec un pas de 77,9 mm. S\u00e9rie 2510<\/strong> (EP-2510, EP-2510F1, EP-2510F2, EP-2510H) \u00e0 un pas de 78,1 mm offre la configuration \u00e0 biellettes coud\u00e9es de capacit\u00e9 de charge maximale de la gamme.<\/p>\n

Chains marked with an asterisk (*) in the EP model number are bush chains – the roller is replaced by a sleeve, and the d1 dimension in the specification table refers to the external diameter of the bush rather than an outer roller. The F suffix designations (F1, F2, F3, F4, F7) identify different plate geometry variants used by specific OEM manufacturers. The H suffix indicates a heavy plate variant with thicker link plates for higher fatigue life. The SH suffix indicates a super-heavy plate variant. All EP cranked-link chains are manufactured from alloy steel with heat-treated plates, case-hardened pins and bushes, and precision-ground pin diameters. Pre-loading is applied to all assembled chains before final pitch measurement and despatch.<\/p>\n<\/div>\n

Cranked-Link Chain – Key Technical Features<\/h2>\n
\n
\n

G\u00e9om\u00e9trie de la plaque coud\u00e9e<\/h3>\n

La plaque de liaison est coud\u00e9e vers l'ext\u00e9rieur au niveau de l'axe, ce qui permet \u00e0 toutes les plaques de l'ensemble d'avoir le m\u00eame profil coud\u00e9. Ceci autorise l'utilisation d'un axe et d'une douille de plus grand diam\u00e8tre, \u00e0 pas \u00e9gal, par rapport \u00e0 une cha\u00eene \u00e0 plaques plates, augmentant ainsi la surface d'appui et la r\u00e9sistance \u00e0 la fatigue sans accro\u00eetre la largeur ni le pas de la cha\u00eene. Cette g\u00e9om\u00e9trie est particuli\u00e8rement efficace pour les transmissions de chariots \u00e9l\u00e9vateurs et de v\u00e9hicules, o\u00f9 les contraintes d'encombrement emp\u00eachent l'utilisation d'une cha\u00eene standard \u00e0 pas plus grand.<\/p>\n<\/div>\n

\n

Maintenance simplifi\u00e9e sur le terrain<\/h3>\n

All links in a cranked-link chain – running links and connecting links – use the same plate profile. This means there is no risk of fitting a standard inner plate connecting link in place of a cranked plate, as can happen with conventional roller chains. Field maintenance technicians can disconnect and rejoin the chain at any position without needing a different connecting link type, reducing both the risk of incorrect reassembly and the number of spare parts that need to be carried on site.<\/p>\n<\/div>\n

\n

Densit\u00e9 de charge \u00e9lev\u00e9e<\/h3>\n

At pitch for pitch, cranked-link chains carry higher loads than equivalent standard flat plate chains because the larger pin and bush diameter provides greater joint bearing area. The EP-SS568H series at 77.9 mm pitch reaches 515 kN average tensile strength and the EP-SS568HF3 reaches 562 kN – performance levels that would require a significantly larger pitch standard roller chain to match. This is why cranked-link chains are preferred in compact drive applications where pitch and sprocket size cannot be increased.<\/p>\n<\/div>\n

\n

Plusieurs variantes de plaques d'immatriculation<\/h3>\n

Les variantes commen\u00e7ant par F (F1, F2, F3, F4, F7) correspondent \u00e0 diff\u00e9rentes g\u00e9om\u00e9tries de plateaux d\u00e9velopp\u00e9es pour des plateformes sp\u00e9cifiques de chariots \u00e9l\u00e9vateurs et de v\u00e9hicules industriels. Chaque constructeur sp\u00e9cifie des dimensions de plateau diff\u00e9rentes afin d'adapter la g\u00e9om\u00e9trie de ses pignons et le d\u00e9gagement de son ch\u00e2ssis. EP dispose de l'outillage de production pour tous les principaux profils de plateaux et peut fabriquer des cha\u00eenes de remplacement pour n'importe quelle variante sans imposer de commande minimale pour l'outillage, si la r\u00e9f\u00e9rence de la cha\u00eene est d\u00e9j\u00e0 enregistr\u00e9e dans sa base de donn\u00e9es de production.<\/p>\n<\/div>\n

\n

Composants en acier alli\u00e9 trait\u00e9 thermiquement<\/h3>\n

Toutes les plaques de cha\u00eene coud\u00e9e EP sont trait\u00e9es thermiquement apr\u00e8s formage afin d'obtenir la combinaison requise de r\u00e9sistance \u00e0 la traction et de ductilit\u00e9. Les axes sont en acier alli\u00e9 tremp\u00e9 et rectifi\u00e9 aux dimensions requises. Les bagues (pour les cha\u00eenes \u00e0 bagues marqu\u00e9es d'un ast\u00e9risque) sont c\u00e9ment\u00e9es et rectifi\u00e9es. Les rouleaux (pour les cha\u00eenes \u00e0 rouleaux) sont usin\u00e9s avec pr\u00e9cision et tremp\u00e9s. L'ensemble est pr\u00e9contraint apr\u00e8s le montage de la cha\u00eene afin de compenser tous les jeux d'articulation et d'\u00e9liminer l'allongement initial lors de l'installation.<\/p>\n<\/div>\n

\n

Variantes de Bush Chain<\/h3>\n

Models marked with an asterisk (*) – including EP-*SS588F4, EP-*MXS882F2, EP-*MXS3011F1, EP-*MX603, and EP-*MXS882F2 – are bush chain variants where no separate outer roller is fitted. The bush surface contacts the sprocket tooth directly. Bush chains have a slightly lighter weight than equivalent roller chains at the same pitch and are suitable for low-speed drives where the chordal impact that would cause roller fatigue under high-speed sprocket engagement is not present. The d1 dimension for these chains is the external diameter of the bush.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Applications<\/h2>\n
\n
\n

Entra\u00eenements principaux des chariots \u00e9l\u00e9vateurs<\/h3>\n

EP-SS588, EP-SS568H, EP-2512, and EP-2510 series chains are the primary specification for forklift truck main drive and mast chain applications. Forklift drives are among the most demanding for chain – very high load at low speed, frequent reversals under full load, exposure to contamination, and the requirement for very long service life between replacements. The cranked-link geometry provides the high joint bearing area needed to achieve this service life in the compact drive configuration of a forklift transmission.<\/p>\n<\/div>\n

\n

Machines agricoles<\/h3>\n

EP-MXS432, EP-1409F1, EP-R3112, and EP-SS2065 series cranked-link chains for combine harvester threshing drum drives, header auger drives, and grain tank unloading drives. These applications combine intermittent very high torque peaks – particularly when the drum processes a dense section of crop – with the need for compact drive geometry and long field service life. The cranked-link design handles the shock loading better than equivalent flat plate chains in these conditions.<\/p>\n<\/div>\n

Les s\u00e9ries EP-2010, EP-2010H, EP-2010SH, EP-2512 et EP-SS568H sont destin\u00e9es aux transmissions finales de v\u00e9hicules industriels, aux cha\u00eenes principales de chariots \u00e9l\u00e9vateurs \u00e0 port\u00e9e variable, aux m\u00e9canismes d'orientation de chariots porte-conteneurs et aux transmissions par cha\u00eene d'engins de chantier. Ces applications exigent une tr\u00e8s haute r\u00e9sistance \u00e0 la traction de la cha\u00eene, qui doit s'int\u00e9grer \u00e0 la g\u00e9om\u00e9trie existante entre les pignons. La cha\u00eene EP-SS568HF3, avec une r\u00e9sistance \u00e0 la traction moyenne de 562 kN, est particuli\u00e8rement adapt\u00e9e aux applications les plus exigeantes de cette cat\u00e9gorie.<\/p>\n<\/div>\n<\/div>\n

\nQu'est-ce qu'une cha\u00eene \u00e0 maillons coud\u00e9s et en quoi diff\u00e8re-t-elle d'une cha\u00eene \u00e0 rouleaux standard\u00a0?<\/summary>\n
A standard roller chain uses two different plate profiles: flat inner plates with the bush pressed in, and flat outer plates with the pin pressed in. A cranked-link chain uses one plate profile for all links – the plate is bent (cranked) outward at the pin hole, so the pin diameter can be larger than the inner width would normally allow in a flat plate design. This means the chain can carry a larger pin and bush at the same pitch, giving higher joint bearing area and tensile strength without increasing chain width or pitch. The practical effect is that a cranked-link chain provides higher load capacity in the same mounting envelope as a standard chain.<\/div>\n<\/details>\n
\nQue signifient les chiffres commen\u00e7ant par F (F1, F2, F3, F4, F7)\u00a0?<\/summary>\n
Les num\u00e9ros commen\u00e7ant par F identifient diff\u00e9rentes g\u00e9om\u00e9tries de plaques d\u00e9velopp\u00e9es pour des constructeurs d'\u00e9quipements d'origine (OEM) sp\u00e9cifiques. Les diff\u00e9rents constructeurs de chariots \u00e9l\u00e9vateurs et de v\u00e9hicules industriels sp\u00e9cifient des largeurs, hauteurs et largeurs int\u00e9rieures de plaques, ainsi que des longueurs d'axes l\u00e9g\u00e8rement diff\u00e9rentes pour une m\u00eame cha\u00eene au pas nominal, afin de s'adapter \u00e0 la g\u00e9om\u00e9trie de leurs pignons, aux d\u00e9gagements du ch\u00e2ssis et aux configurations de fixation propres \u00e0 chaque constructeur. EP dispose des outillages de production pour toutes les principales variantes commen\u00e7ant par F de sa gamme de produits. Lors de la commande d'une cha\u00eene de remplacement, veuillez toujours indiquer la r\u00e9f\u00e9rence EP compl\u00e8te, y compris le suffixe F, afin de garantir la compatibilit\u00e9 dimensionnelle avec les pignons et la configuration d'entra\u00eenement existants.<\/div>\n<\/details>\n
\nPuis-je identifier une cha\u00eene de remplacement \u00e0 partir d'un \u00e9chantillon de la cha\u00eene us\u00e9e\u00a0?<\/summary>\n
Oui. Veuillez envoyer un \u00e9chantillon d'au moins 3 maillons connect\u00e9s \u00e0 EP pour un relev\u00e9 dimensionnel. Les principales mesures effectu\u00e9es par EP sont\u00a0: le pas (distance entre les centres des 3 axes divis\u00e9e par 2), le diam\u00e8tre des rouleaux ou des bagues, la largeur int\u00e9rieure entre les plaques au niveau de la jonction, le diam\u00e8tre des axes, la hauteur totale des plaques (h\u00b2) et l'\u00e9paisseur des plaques. \u00c0 partir de ces mesures, EP identifiera le produit le plus adapt\u00e9 dans sa gamme et v\u00e9rifiera la r\u00e9f\u00e9rence EP correspondante. Pour les remplacements urgents, mesurez le pas en pla\u00e7ant 10 axes dans une rang\u00e9e de trous perc\u00e9s sur une surface plane et en mesurant la distance entre les axes ext\u00e9rieurs, puis en divisant par 9 pour obtenir le pas moyen. Mesurez \u00e9galement le diam\u00e8tre et la largeur int\u00e9rieure des rouleaux \u00e0 l'aide d'un pied \u00e0 coulisse et fournissez des photos de la cha\u00eene prises de face et de profil.<\/div>\n<\/details>\n
\nQuelle est la diff\u00e9rence entre les variantes H et SH (par exemple EP-2010, EP-2010H, EP-2010SH)\u00a0?<\/summary>\n
The base designation (EP-2010) uses the standard plate thickness for that chain series. The H variant (EP-2010H) uses a heavier plate – typically 20% to 35% thicker – giving higher fatigue resistance and a higher tensile strength rating. The SH variant (EP-2010SH) uses a super-heavy plate – even thicker than the H variant – for the most demanding applications where the standard and H variants have been found to have insufficient plate life. The H and SH variants have the same pitch and roller diameter as the base chain, so they fit the same sprockets; the plate thickness change does not affect sprocket engagement.<\/div>\n<\/details>\n
\nComment les cha\u00eenes \u00e0 maillons coud\u00e9s sont-elles lubrifi\u00e9es dans les applications de chariots \u00e9l\u00e9vateurs et de v\u00e9hicules ?<\/summary>\n
Most forklift and industrial vehicle cranked-link chain drives use a combination of initial factory-applied grease and periodic field lubrication with chain oil applied by brush or spray at each maintenance interval. Unlike high-speed power transmission drives that can use drip oilers or bath lubrication, forklift drives typically operate at very low speed in contaminated environments where conventional lubrication systems are impractical. EP recommends using a penetrating chain lubricant that can reach the pin-bush interface rather than a heavy grease that stays on the outer surface. Apply lubricant to the chain as it is slowly rotated through the drive to reach all joint positions. Frequency depends on operating environment – at minimum, lubricate at each planned maintenance interval for the vehicle.<\/div>\n<\/details>\n
\nPouvez-vous fournir des variantes non standard qui ne figurent pas dans le tableau des sp\u00e9cifications\u00a0?<\/summary>\n
Yes. The specification table shows the standard EP production programme for cranked-link chains. For chain models not listed – whether from other manufacturers, or custom configurations with non-standard pitch, inner width, or plate geometry – EP can produce replacement chains from a dimensional survey of a sample chain or from a customer drawing. Minimum order for non-standard cranked-link chains is typically 5 metres or one complete circuit, whichever is greater. Lead time for non-standard variants is 15 to 25 working days depending on the tooling required. For very high volume requirements, EP can hold non-standard variants as managed stock.<\/div>\n<\/details>\n<\/div>\n

“We operate a fleet of 140 counterbalance forklifts across three warehouses. We switched to EP-SS568H chains for our 7-tonne units two years ago. Average chain replacement interval has gone from 4,500 hours to 7,200 hours. The dimensional consistency is excellent – we have never needed to adjust sprocket centres after an EP chain installation.”<\/p>\n

“We maintain combine harvesters for a large cooperative. The EP-SS2065 chains for threshing drum drives have given us two full harvests without replacement. The previous chains from another supplier needed replacement mid-season in year 1. The EP chains showed 1.4% elongation at the end of the second harvest, still within limit.”<\/p>\n

“We needed EP-2512F4 chains as OEM replacement for a heavy reach stacker fleet. EP identified the chain from our sample within 3 working days, confirmed the dimensional match, and shipped 8 complete circuit lengths within 12 working days. The chains fitted without adjustment. We now hold EP-2512F4 on our approved vendor list for this application.”<\/p>\n

“We distribute forklift parts across Southeast Asia. EP cranked-link chains cover over 85% of the models we encounter in the field. The batch-to-batch consistency is the key advantage – our technicians know that an EP chain will fit the first time without measuring every individual chain. That reliability is worth more than a small price difference.”<\/p>\n
