Unlike roller chains, leaf chains consist of only pins and plates, so they achieve extremely high breaking forces. They are used wherever loads need to be raised, hoisted or pulled. One of the principal uses of leaf chains is in fork lift truck masts, but they are also used as counterweight chains in machine tools, as draw bench chains or in container loaders.
While the JWIS brand focuses mainly on the specialised manufacture of works-standard compliant leaf chains, the product brand ELITE offers a broad and comprehensive range of leaf chains in accordance with various standard series. In addition to these standard products, special versions, end pieces and attachments are also available e.g. with hose routings and hydraulic mast guards. As well as moving loads safely and reliably, iwis leaf chains can be adapted to meet customer-specific requirements and are compliant with EC Machinery Directive 2006/42/EC.
iwis link plates with optimised geometry are precision-formed, heat-treated, shot-peened and have a particularly high contact ratio. A smooth, hardened surface gives the pins added wear resistance. Thanks to the improved press-fitting of pins and outer plates, the fatigue strength of these chains is also higher. iwis offers a wide and varied range of standard leaf chains, and many other special versions manufactured to works standards are also available.
