Coil Lifter and Roller Lifting Machine

Executive summary

A mobile coil lifter and roller turning tool engages wrapped cylindrical coils through the centre core, lifts the load clear of the floor, and rotates it 90 degrees between eye-horizontal and eye-to-sky (vertical) orientations. Guided by a single operator via an ergonomic wheeled chassis, the equipment eliminates overhead crane dependency, reduces strain hazards, and prevents outer layer impact damage during cross-bay transit. Core dimensions, lifting stroke, and weight ratings are engineered to specific coil specifications.

Why lift and turn coils

Coils of metal strip, polymer film, laminated sheet, and heavy paper present distinct handling challenges due to their weight, surface sensitivity, and shifting center of gravity. Delivered horizontally on skids or pallets (eye-horizontal), these loads frequently require 90-degree reorientation to eye-to-sky (vertical) for slitting, spooling, or packaging stages. Manual maneuvering or makeshift rigging creates severe risks of core deformation, telescoping, dropped loads, and ergonomic injury.

This dedicated turning tool keeps the turning axis close to the ground, containing the rotational envelope within a stable footprint. By replacing multi-operator overhead crane rigging with a guided, single-operator handling system, plants streamline material transit, eliminate coil edge damage, and ensure controlled positioning throughout the transition.

What it does

The machine operates as an autonomous, mobile lifting and turning station tailored for cylindrical goods and wrapped rolls. Built on an ergonomic wheeled chassis with a heavy-duty vertical mast, the unit features an articulated cantilever arm equipped with expanding inner-diameter (ID) jaws.

The arm enters the coil bore, locks onto the core wall, raises the workpiece through an electro-mechanical lift column, and rotates the load smoothly between horizontal and vertical planes. Once locked in position, the operator transfers the coil directly across shop-floor aisles without requiring fixed crane networks or secondary transport dollies.

How it works: arm, jaws and column

Operation relies on three coordinated mechanical assemblies:

  • Expanding Mandrel & Jaws: The cantilever tooling enters the core bore. Actuated expanding segments engage the internal core surface uniformly, delivering high-friction grip without crushing or scratching sensitive inner wraps.
  • Electro-Mechanical Lifting Column: An integrated motorized lifting column provides vertical travel, lifting the suspended coil smoothly clear of ground obstacles with built-in travel limit switches.
  • 90° Self-Locking Rotation Mechanism: The gripping assembly pivots between horizontal and vertical planes, actuated through a self-locking gear drive and manual handwheel to prevent uncontrolled gravitational roll.
  • Ergonomic Chassis & Steering: Dual swivel casters with directional locks and an ergonomic push bar allow smooth positioning and steering across level concrete plant floors.

Cycle and control

A standard handling cycle follows a structured four-stage sequence:

  1. Core Engagement: The operator steers the mobile unit to the coil, aligns the mandrel arm with the center bore, and advances the tool until the gripping segments fully seat inside the core.
  2. Bore Clamping & Elevation: Expanding jaws are deployed to clamp the inner diameter. The operator activates the column push-button control on the handle to raise the coil clear of floor resting fixtures.
  3. Controlled 90° Turning: Using the handwheel-actuated worm gear drive, the operator smoothly turns the suspended coil into the target vertical or horizontal orientation, where it automatically locks.
  4. Transit, Offloading & Reset: The operator wheels the tool to the receiving station, lowers the coil to a stable rest pad, retracts the expanding jaws, and withdraws the arm. Guidance is manual, while all primary lifting loads are driven electro-mechanically.

What the footage shows

The engineering demonstration video validates the operational kinematics and load management of the tool under production floor conditions:

  • Axial Alignment & Internal Clamping: Insertion of the cantilever mandrel into the core of a stretch-wrapped film coil, followed by segment expansion to achieve rigid ID engagement.
  • Stable Vertical Travel: Smooth ascent via the powered column, demonstrating steady vertical translation without deflection or erratic oscillation.
  • 90° Orientation Shift: Continuous transition from eye-horizontal loading pose to eye-to-sky vertical presentation via the reduction-drive handwheel.
  • Single-Operator Floor Maneuvering: Controlled manual floor transit demonstrating low rolling resistance and directional control under full working load.

Power Architecture Plant AC utility supply or requirement for cord-free, rechargeable battery-powered mobility

Operation and safety

Safe and consistent handling requires strict adherence to fundamental industrial protocols:

  • Clamp Verification: Confirm complete engagement and positive radial jaw expansion against the core wall prior to initiating vertical elevation.
  • Exclusion Zone: Enforce a strict personnel exclusion perimeter around the suspended payload during turning and lifting actions; never traverse under a raised load.
  • Floor Path Inspection: Move the loaded unit strictly on level, debris-free floors. Sudden changes in floor grade or wheel drop-offs must be avoided when the center of mass is elevated.
  • Safe Release Discipline: Lower the coil fully onto a certified, stable rest surface or pallet before retracting the expanding mandrel segments.
  • Preventive Maintenance: Conduct routine visual and functional inspections of the lifting chain/spindle, caster bearings, structural weldments, and jaw friction pads in accordance with the operating manual.

Engineering FAQ

Q: What core types can the expanding jaws safely grip? A: The expandable jaws accommodate standard steel, plastic, composite, and heavy-duty paperboard cores. Contact pads can be fitted with polyurethane, vulcanized rubber, or serrated steel faces to protect sensitive core layers while ensuring positive friction lock.

Q: Does the turning mechanism hold position automatically if the operator releases the handwheel? A: Yes. The rotation assembly integrates a self-locking worm reduction gear. The coil remains firmly held at any intermediate tilt angle between 0° and 90° without risk of gravitational drift or freewheeling.

Q: Can this unit completely replace an overhead bridge crane for inter-bay coil transfer? A: For point-to-point transfers between slitting, packing, and staging buffers within the rated payload capacity, the mobile lifter eliminates overhead crane waiting times and avoids hazardous sling/c-hook rigging.

Q: Is external power tethering required during floor transit? A: Depending on configuration, the unit can be supplied via a trailing cable for stationary cells, or equipped with an onboard industrial 24 V DC battery and charging system for untethered floor transport.

Q: How does the tool accommodate different core inner diameters? A: Quick-change modular expansion shoes or interchangeable mandrel sleeves can be fitted to the primary gripping shaft to span diverse core sizes across multi-product lines.
