Coil Cradles are made to help unwind coils in rough production environments. Mostly combined with a straightening unit, they work with narrow and thick materials. Built to last, Coil Cradles offer quite a few advantages Simple handling of even hightensile materials with strong clockspring, short setup times, an elaborate coil handling concept which gives a chance to rewind of unfinished coils. By using serial straightening units, type RMA and RMZ, everything is well fitting. To achieve short mounting times and easy accessibility, the complete machine body features a one piece tiebar design machined with most modern CNC equipment. Coil Cradles, CradleStraighteners and CradleFeederStraighteners thus are very efficient too. Consequently, their compactness, efficiency, safety and operator friendliness melt into a coil handling solution which underlines GSW’s lead in technology. Performance data Up to 8 t coil weight, 700 mm stock width and up to 13mm thickness

Upenders are designed to safely tilt big and heavy coils – either from horizontal into vertical or reversed. This fast and easy coil handling solution gets rid of “adventurous” tilting methods that often will endanger the operator. Chains and other lifting aids which damage the coil rims become obsolete. Upenders allow 90 degrees tilting of coils; Combination machines will also rotate 180 degrees. Both can handle up to 25 tons.
