Hydraulic Decoilers
Our hydraulic decoilers carry coils from 4,000 kg to 15,000 kg and run strip widths up to 1,600 mm. Mandrel expansion is hydraulic; a pneumatic hold-down arm and laser sensor loop control come as standard.

Hydraulic mandrel expansion
A hydraulic cylinder expands the mandrel and clamps the coil from its inner diameter. On 4–15 t coils no operator effort is needed to clamp.
Pneumatic hold-down arm
The hold-down arm presses on the outer wrap of the coil and stops it springing loose when the strap is cut. Standard on every hydraulic model.
Laser sensor loop control
A laser sensor measures the loop between the decoiler and the next unit and matches decoiler speed to the line, so the strip neither stretches nor touches the floor.
Motor driven or brake type
Hydraulic decoilers are motor driven. Where the line itself pulls the strip, a brake-instead-of-motor configuration is available.
Frequently asked
Common questions
What is a hydraulic decoiler?
A machine that carries a heavy coil on a mandrel and unwinds it into the line at a controlled speed. A hydraulic cylinder expands the mandrel and clamps the coil from its inner diameter. Servosteel's hydraulic series carries coils from 4,000 to 15,000 kg.
What capacity and strip width does a hydraulic decoiler handle?
Capacities are 4,000, 6,000, 10,000 and 15,000 kg, each with models in several widths. Material width is 70–600 mm at 4 t, 70–1,000 mm at 6 t, 70–1,500 mm at 10 t and 100–1,600 mm at 15 t. Every model is in the table.
Which coil diameters does a hydraulic decoiler accept?
On every hydraulic model the coil inner diameter is 470–570 mm and the outer diameter Ø 1,400 / 1,600 mm.
Should I choose a hydraulic or a mechanical decoiler?
Coil weight decides. The mechanical series carries 500–4,000 kg, the hydraulic series 4,000–15,000 kg. Above 4 t, on wide strip and with frequent coil changes, choose a hydraulic decoiler; at 4 t both series exist and the hydraulic one takes clamping off the operator. On heavy lines we recommend it together with a hydraulic coil car.
What do you need for a hydraulic decoiler quotation?
The weight of your heaviest coil, strip width and thickness range, coil inner and outer diameter, the line the decoiler will feed (press feeding, slitting, cut-to-length or roll forming) and line speed. Also tell us whether you need a coil car.
