Hydraulic Decoiler Machine Manufacturer for 5T-20T Coil Feeding
Henli builds heavy duty hydraulic decoiler machines and hydraulic uncoilers for steel coil unwinding lines that need safe loading, stable mandrel expansion, and controlled feeding before a straightener, feeder, shear, press, laser line, roll former, or tube mill.
- For buying intent: select by coil weight, width, thickness, inner diameter, outer diameter, line speed, and downstream machine.
- For powered expansion: hydraulic actuation expands the mandrel without manual adjustment; it does not by itself prove higher load capacity or strip tension.
- For safer changeovers: pressing arm, outboard support, hydraulic coil loading car, and retaining arm are matched to coil tension and load.

Choose by coil data first
The model is selected from real coil load, strip width, thickness, coil ID/OD, line speed, and downstream machine. For 10T and custom-built 20T projects, compare the heavy-load guide and submit the complete coil and line data before requesting a quote.

Review hydraulic decoiler structure and partsEngineered for Heavy Industry and Stable Coil Control
The heavy duty hydraulic decoiler is the first stability point in a metal coil processing line. HENLI supplies standard models from 5 to 15 tons and up to 1600 mm wide, and can engineer and manufacture custom configurations up to 20 tons and 1800 mm. The standard model table is a selection reference rather than a manufacturing capability ceiling; each custom machine is configured from the actual coil envelope, load path, support, drive, foundation and line data.
It serves as a critical unwinder for metal fabrication, stamping, rolling mills, shearing, and cut-to-length lines. The hydraulic mandrel, heavy frame, VFD drive, braking, and loop sensing help keep coil feeding stable before leveling and feeding.
Why Choose Henli Heavy Duty Hydraulic Decoilers?
The machine value is concentrated in hydraulic grip, structural rigidity, mandrel protection, and controlled acceleration or braking. These points matter most when the coil is heavy, wide, or difficult to handle manually.
Heavy coil control depends on four engineering details.
Instead of treating every selling point as a separate card, the key selection points are grouped as a technical checklist for buyers comparing hydraulic decoilers.
Hydraulic Expansion System
Powered mandrel expansion: hydraulic actuation expands the mandrel segments within the approved coil-ID range. Buyers may also search for this assembly as a hydraulic expanding mandrel or uncoiler mandrel; frame, shaft, bearings, support and load distribution still determine the complete machine capacity.
Pressure-loss boundary: the hydraulic circuit, mechanical retention and safe response to power or pressure loss must be defined by the approved design and manual; secure holding must not be assumed.
Heavy-Duty Frame
Annealed structure: the welded profile steel and A3 steel plate body is annealed to reduce internal stress and long-term deformation.
Precision concentricity: bearing housings are bored in one setup to improve spindle concentricity and reduce radial runout.
Protected Mandrel
4-segment design: the mandrel blade arc matches common coil inner diameters.
Hard chrome surface: polished, wear-resistant blade surfaces help protect material contact areas during coil loading and unwinding.
Intelligent Drive
Vector VFD control: a geared motor with inverter control delivers smooth, high-torque drive.
Braking function: automatic braking helps manage coil inertia and reduce mechanical shock during stop cycles.

Accessory Choices for Faster Changeover and Safer Coil Handling
The standard accessory image is separated from the optional modules. Buyers can first see what comes with the machine, then review which optional devices should be added for heavy, wide, thick, or high-tension coils.
Standard Accessories
The top image represents the standard accessory set. These items are treated as the base configuration, not optional add-ons.
Optional Accessories Selected by Coil Condition
The following eight devices are selected case by case according to coil weight, thickness, yield strength, width, line speed, and loading method.
Pneumatic Pressing Arm
Applies configured holding force to help contain springy outer wraps during loading or threading. Selection depends on material strength, coil condition and risk review; there is no universal 2.0 mm threshold.
Motorized Pressing Arm
Provides active traction for exceptionally thick or heavy-gauge material, helping feed the rigid coil head into the straightener during changeover.
Variable Frequency Drive
Enables stepless speed control and soft start/stop so the decoiler can respond to loop demand. Commissioning must verify the buffer and line interface; VFD control alone does not prove synchronization.
Hydraulic Expansion System
Replaces manual hand-crank expansion with hydraulic cylinder force, gripping the coil ID securely and reducing labor during coil setup.
Hydraulic Coil Loading Car
Lifts and traverses the coil to align with the mandrel. Selection depends on coil mass/geometry, center height, travel, site handling and risk assessment; there is no universal 5 ton threshold.
Outboard Support Arm
Supports the free end of the mandrel to limit deflection. Whether it is required, and whether its actuation is hydraulic, must be confirmed from the approved coil load, mandrel geometry and support calculation rather than one universal tonnage threshold.
Hydraulic Coil Retaining Arm
Provides powered side guidance and restraint during approved loading and payoff procedures. It does not by itself prevent telescoping, and selection depends on coil width, winding condition, material behavior and the risk assessment.
Hydraulic Material Support Arm
Acts as a bridge during setup, lifting and guiding the loose strip into the next leveler or feeder for safer hands-free threading.
Hydraulic Decoiler in a Circle Cutting Production Line
This video shows a hydraulic decoiler in a circle-cutting line. The decoiler supplies strip into the documented buffer and downstream feeding arrangement; tension control is not assumed and must be evaluated from the complete line design.
- Line role: hold and unwind the coil before the blanking process.
- Buyer focus: coil weight, width, material behavior, surface-contact points, loop response and the downstream interface.
- Useful options: hydraulic expansion, VFD, pressing arm, and loading car when coils are heavy or frequent changeovers are needed.
Common Industrial Applications of Hydraulic Decoilers
Hydraulic decoilers are considered when coil weight, width, coil-ID engagement or the approved handling method makes manual expansion unsuitable. Steel coil and sheet-metal lines are common routes; stainless steel and aluminum coil can also be evaluated after strength, surface sensitivity, thickness-width combination, coil mass and downstream process are confirmed. The final configuration depends on the complete coil and line data.
Metal Stamping
Supplies coil strip into the buffer, straightener and feeder arrangement used before a press. Loop geometry, stopping behavior and downstream demand must be commissioned for the specific progressive-die line.
Roll Forming
Supports controlled buffer supply for roll forming machines that produce roofing sheets, C/Z purlins, shelving, and long metal profiles.
Tube and Pipe Manufacturing
Provides heavy-duty uncoiling for automated tube mills, helping deliver stable strip material to the welding line for steel pipe and tube production.
How Hydraulic Decoilers Fit Into Complete Coil Processing Lines
The hydraulic decoiler is usually the first machine in a coil handling line. These solution examples keep the original content while making each line configuration easier for buyers to scan.
Compact 3-in-1 NC Servo Feeder Solution
A 3-in-1 machine integrates a Hydraulic Decoiler, precision straightener, and NC servo feeder into one compact chassis. Compared with a split line, a 3-in-1 layout can shorten the material path and footprint; actual space, leveling and feeding performance depend on the selected model and layout.
- Best for modern stamping facilities with limited floor space.
- Shorter material path between leveling and feeding.
- Useful for precise press feeding and high-strength material processing.
Economical Cut-to-Length Line
When paired with a precision leveler, NC Servo Feeder, and hydraulic shearing machine, the hydraulic decoiler forms a practical automatic cut-to-length line for customers who need professional shearing without a high-end European line budget.
- Mandrel function: hydraulic expansion supports repeatable coil-ID engagement; loop control or measured tension requires separate sensors and controls.
- Changeover support: powered loading and expansion can reduce manual handling steps when included in the approved layout and procedure.
- Evidence boundary: any customer-life or uptime statement requires a traceable project and service record; it is not used as a general series guarantee here.
Aluminum Circle Blanking Line
A hydraulic decoiler can supply an aluminum circle-cutting line and may be paired with a zigzag feeder. Surface protection and material yield depend on the verified strip-contact path, restraint method, buffer, feeder setup and nesting program; hydraulic expansion alone is not a tension-control or yield guarantee.
- Surface protection: hydraulic expansion grips concentrically from the core.
- Nesting and yield: confirm feeder accuracy, strip guidance and the programmed circle layout from the complete line data.
- Safety and speed: hydraulic handling reduces manual loading of heavy aluminum coils.
