Machine Concepts’ Heavy Duty Decoilers incorporate a robust design to handle coil loads up to 55,000 pounds per mandrel and coil widths up to 50 inches. These decoilers are typically paired with a Machine Concepts G2 or H2 Precision Straightener.
Due to the heavy coil loads on this series of decoilers, the standard features include hydraulic expansion and hydraulic powered mandrel rotation. The hydraulic expansion is accomplished through the use of wedges. The wedge design allows for maximum stability and strength when expanding on the heaviest of coils. With light and medium duty decoilers, the material can be threaded into the straightener by manually rotating the decoiler mandrel to payoff material. With heavy coil loads, Machine Concepts incorporates a hydraulic motor to payoff material and assist in threading a strip into the straightener.
