A steel coil is loaded onto the expanding mandrel. The mandrel grips the inner diameter and a motorized or hydraulic drive rotates the drum to pay out strip. A pneumatic or disc brake maintains back tension so the strip feeds evenly into the straightener, feeder, or punch press without slack or overrun.
Heavy Duty Decoiler
Heavy Duty Decoilers for Large Steel Coil Unwinding
Heavy duty decoilers are built for coils from 3 tons to 20 tons. A robust frame, hydraulic mandrel expansion and powerful motor drive handle the heaviest coils safely. An optional coil loading car lifts coils from floor to mandrel, reducing operator effort and crane time. FANTY configures every heavy-duty decoiler to the coil dimensions and line speed of your press.
What a Heavy Duty Decoiler Does for Your Line
Motorized or hydraulic drive
Coils are unwound smoothly with controlled tension, protecting surface finish and keeping line speed stable.
Expandable mandrel system
Grips the coil inner diameter securely for safe handling during loading and unwinding.
Optional coil loading car
Lifts heavy coils from floor to mandrel, reducing crane time and operator risk.
Factory-configured builds
Cover a wide weight and width range with custom specifications available on request.

Heavy Duty Decoiler Frequently Asked Questions
What coil sizes can these decoilers handle?
Models range from 200 mm to 1,500 mm coil widths and from 500 kg to 20 tons coil weight. Tell us your coil data and we recommend the right model.
Do you provide voltage and plug customization?
Yes. Control voltage, motor voltage and plug type are configured to your local standard before shipping.
How long is production and delivery?
Standard models ship in 15–25 working days. Custom configurations may need 30–40 days. We confirm the schedule when you place the order.
What spare parts should I keep in stock?
We recommend keeping mandrel segments, brake pads and proximity sensors. A starter spare-parts list is included with every machine.
What is the warranty period?
One year from the bill of lading date. Technical support and replacement parts are available for the lifetime of the machine.
Do you offer installation and training?
Yes. We supply English manuals, video guides and can arrange on-site or remote commissioning support.
