Paper mill cranes, process overhead crane for paper mills

• Designed for paper rolls ranging 1 ton to 50+ tons, depending on roll diameter and width.
• Common roll diameters: 1–3 meters; width: 1–3 meters.
• Load depends on the type of J-hook and crane: standard J-Hook for 5–20 tons; reinforced designs for 30–50 tons.

Intelligent control is adopted for the parent roll handling crane to meet busy productivity in the paper mill with high work efficiency and high lifting precision. With the encoder, sensor , and the programmable PLC , the industrial overhead crane crane system can meet your paper mill requirements which will largely improve your working efficiency and the safety during operation.

To combat the harsh application and ensure crane safety, anti-swing device is installed on the overhead crane systems to prevent the happening of accident together with the wireless communication module to ensure safety of the crane equipment under high speed working condition .

• Roll-friendly design: The hook cradles the roll without deforming it or damaging the edges.
• High efficiency: Can lift and transport rolls quickly, reducing downtime in production.
• Safety: Reduced risk of roll slipping compared to standard sling methods.
• Flexible operation: Compatible with single or double girder overhead cranes.
• Customizable: Hooks can be fixed or adjustable to handle different roll diameters.

• Often paired with electric wire rope hoists or air hoists for smooth lifting.
• Frequently used in FEM/DIN standard cranes for reliability in continuous operations.
• Can be integrated with automation or conveyor systems for semi-automated roll handling.

Example: A paper mill producing 10-ton jumbo rolls can use a J-hook crane with a 15-ton capacity, mounted on a single or double girder overhead crane, to safely transport rolls from the reel-up section to the cutting and packaging area.

The wet end crane has multiple functions and can be used as a maintenance crane for the paper machine and also as a dry end crane backup. These paper mill cranes can be used to erect the paper machine, assist in roll machine maintenance, and lift and transport machine parts.

The specially designed overhead cranes help to change the press or dryer section rolls of the paper machine quickly and accurately. They ensure safe handling of heavy press rolls under the warm, humid, and chemically aggressive conditions common in paper-making workshops.

• Jumbo roll handling: Lifting and transferring large paper rolls from production to storage or finishing lines.
• Machine installation and alignment: Assisting in erecting new paper machines or moving large equipment during upgrades.
• Maintenance of auxiliary equipment: Supporting maintenance for pulping, coating, calendaring, and rewinding machines.
• Material handling within the workshop: Transporting spare parts, press components, or heavy tools safely and efficiently.
• Automation integration: Can be used with automated roll handling systems to improve workflow and reduce downtime.

• Overhead maintenance cranes are designed for durability in wet, humid, and dusty environments typical of paper mills.
• Customizable spans and lifting capacities allow the crane to fit production halls of various sizes.
• Enhances operator safety and reduces the risk of damage to rolls and machinery during maintenance operations.

• Workstation material handling: Assisting operators in lifting and positioning paper rolls, cores, and components at individual workstations.
• Paper roll finishing areas: Supporting rewinding, slitting, and cutting operations by handling small to medium rolls.
• Maintenance support: Lifting motors, pumps, rollers, and spare parts during equipment repair and servicing.
• Packaging and dispatch zones: Handling wrapped paper rolls, cartons, and palletized products for shipment.
• Auxiliary equipment handling: Supporting operations around coating machines, calendaring units, and deinking systems.

• Small to medium paper rolls (0.5–8 tons)
• Paper cores, shafts, and rollers
• Mechanical components such as motors, gearboxes, and bearings
• Tooling, maintenance equipment, and spare parts
• Palletized goods and packaging materials

• Provides localized lifting coverage, reducing reliance on main overhead cranes and improving workflow efficiency.
• 360º rotation is ideal for open work areas, while 180º or 270º rotation suits wall-side or corner installations.
• Frequently equipped with electric chain hoists or manual hoists for precise and cost-effective handling.
• Ideal for high-frequency, short-distance lifting tasks in paper mills where speed and ergonomics are critical.
• Helps improve operator safety and productivity by minimizing manual handling of heavy rolls and components.

Capacities range from 1 ton for maintenance cranes up to 320 tons for heavy-duty roll handling and machine installation.

• Light-duty cranes (1–5 tons): Used for tooling, small rolls, and spare parts.
• Medium-duty cranes (5–50 tons): Lift parent rolls, felts, and wet end machinery.
• Heavy-duty cranes (50–320 tons): Handle jumbo rolls, press and dryer rolls, and full machine modules.
• Lifting capacity selection depends on workshop, objects handled, and safety margin requirements.

Maintenance cranes lift, align, and transport rolls, equipment, and spare parts efficiently, minimizing downtime and safety risks.

• Workshop maintenance: Light to medium cranes (1–20 tons) handle tools, small motors, and spare parts.
• Machine installation and repair: Heavy-duty cranes (50–150 tons) lift press rolls, dryer rolls, and entire machine sections.
• Crane materials are often corrosion-resistant for wet end or chemical zones.

These hooks allow safe, precise, and fast lifting of parent and jumbo rolls, reducing downtime and roll damage.

• J-Hooks: Lift 5–50 ton rolls horizontally using a mandrel.
• C-Hooks: Rotate or move rolls vertically with 50–150 ton capacity.
• Anti-sway features prevent roll damage in production or storage areas.
• Ergonomic design reduces operator effort and increases throughput.

Cranes are adapted in span, lifting capacity, hook type, and automation to fit workshop layout, load types, and environmental conditions.

• Low headroom cranes fit compact workshops or narrow passages.
• Corrosion-resistant cranes suit humid wet end sections with chemical exposure.
• Heavy-duty cranes (up to 320 tons) handle jumbo rolls or press/dryer sections.
• Semi-automation improves roll handling efficiency and safety.

Anti-sway devices, load sensors, encoders, and PLC controls ensure safe, precise, and reliable operations under heavy and repetitive loads.

• Anti-sway and position sensors prevent roll misalignment.
• Load sensors prevent overloading during lifts up to 320 tons.
• Remote controls improve operator safety in high-traffic areas.
• Corrosion-resistant coatings and robust hoists ensure long-term performance.

Regular inspections, preventive maintenance, and predictive monitoring reduce downtime and enhance safety.

• Inspect wire ropes, hoists, hooks, and structural integrity regularly.
• Lubricate moving parts and check mechanical components for wear.
• Use predictive maintenance with sensors and PLC monitoring to reduce unexpected downtime.
• Schedule maintenance according to load, workshop environment, and crane usage frequency.
