Your Benefit

With their high fatigue strength and high wear resistance, iwis engineered class chains offer a long service life and a high degree of cost-efficiency.  This is achieved by the use of case-hardened pins and bushes, along with hardened and tempered link plates with an effective breaking strength significantly above what is standard in the industry. 


Customized Attachments

In addition, iwis offers a huge variety of application specific attachments for customized use. Depending on style, also welded or integral attachments.
