Linkage Uncoiler

>Home >Products >Coil Handling >Linkage Uncoiler

Hayes Linkage Uncoilers are a 6-tonne capacity single mandrel uncoiler operating using a hydraulic drawbar and linkage system. A 4-leaf mandrel expands and retracts to hold the coil via a hydraulically operated linkage and drawbar system powered by a dedicated onboard hydraulic powerpack mounted inside the uncoiler body. The uncoiler is controlled by a standalone operator’s console that also houses all necessary electrical equipment and can be operated in manual, or automatic mode in tandem with Rollforming machinery.
