Product Detail

Hydraulic Decoiler

A hydraulic decoiler is specialized equipment for metalworking and steel coil handling, engineered to unwind heavy coils with weights ranging from 3 to 25 tons. By using hydraulic power to expand and secure the coil's inner diameter, it simplifies both loading and tensioning, cutting down on manual labor and boosting throughput compared to hand-crank systems.


Applicable Material

✓ Raw Material Type: Handles coils of galvanized and stainless steel, cold- and hot-rolled steel, aluminum, copper, and more.
✓ Coil Width: 5-2000 mm
✓ Coil Thickness: 0.1-6.0 mm
✓ Coil I.D.: 450-520 mm
✓ Coil O.D.: Max 1200 mm
✓ Speed: 15 m/min
✓ Applications: Pressing line / Metal stamping line / Forming line


Brief Profile of Hydraulic Decoiler Machine

Hydraulic decoiler machine overview with hydraulic expansion system

Our hydraulic decoiler machine uses a hydraulic cylinder to expand the mandrel from 450 mm to 530 mm, securing coils up to 25 tons.
A detachable control box with manual buttons lets operators monitor and adjust the uncoiling in real time.
A pneumatic PU-wheel pressing arm applies surface pressure to prevent coil flaring. The robust frame houses the spindle, hydraulic cylinders for tightening and unwinding, and a mobile loading carriage to speed up coil placement.
Widely used as a reliable heavy duty decoiler and standard decoiler machine in automotive, construction, and metal fabrication lines, these machines cut loading time and reduce manual effort for heavy-coil processing.
