Wedge Uncoiler

>Home >Products >Coil Handling >Wedge Uncoiler

Hayes Wedge Uncoilers are a 6-tonne capacity single capstan uncoiler operating using a hydraulic wedge system that provides a sturdy and reliable grip on coils. A 4-leaf mandrel mounted to the top of the uncoiler body via two large heavy duty captive bearings expands and retracts to hold the coil via a hydraulically operated wedge 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.
