A vacuum lifter or a roll manipulator is the most suitable lifting aid for moving rolls. Which solution is best depends on the roll’s material, weight, work environment, and the desired range of motion. The right lifting aid for rolls not only protects your employees from physical strain but also increases the efficiency of your production process. In this article, we answer the most frequently asked questions about roll handling so that you can make an informed decision.
Which type of lifting aid is best suited for which type of castor?
The type of lifting aid for rolls is primarily determined by the material, diameter, weight, and orientation of the roll. For smooth, non-porous rolls such as film, paper, or metal strip, a vacuum lifter is ideal. For heavy or porous rolls, such as textile rolls or cardboard rolls with a rough surface, a mechanical roll manipulator offers greater reliability.
In addition to the material, the working position also plays a role. Should the roll be placed horizontally or vertically? Does it need to be lifted and rotated? Some applications require a combination of both movements, in which case a specialized roll-handling solution with a rotation function is the best choice. Think of placing a paper roll in a printing press or wrapping film around a product on a production line.
- Film and paper rolls: vacuum lifter with suction cups adapted to the roll diameter
- Textile and cardboard rolls: mechanical clamping manipulator or mandrel holder
- Metal rolls and coils: heavy-duty roll manipulator with high lifting capacity
- Small rolls weighing up to 50 kg: ergonomic mobile lifter or manually operated roll carrier
How does a vacuum lifter work when handling rolls?
A vacuum lift for rolls operates using negative pressure: suction cups are placed on the surface of the roll, and a vacuum pump extracts the air, holding the roll securely in place. The lift can then lift, move, and precisely position the roll without the employee having to exert any force.
Modern vacuum lifters for rolls are equipped with special curved or cylindrical suction cups that conform to the round shape of the workpiece. Some models feature a tilting function that allows a roll to be rotated from a horizontal to a vertical position, which is particularly useful when placing rolls into machines or racks.
A vacuum lifter works best on smooth, non-porous surfaces. If you are unsure whether a surface is suitable, we strongly recommend testing the lifter with the specific material first. View our full selection of vacuum lifters to get an idea of the available configurations and capacities.
When is a roller manipulator better than a vacuum lifter?
A roll manipulator is better than a vacuum lifter when the roll’s surface is porous, rough, or uneven, or when the roll’s weight exceeds the capacity of a standard vacuum lifter. A mechanical manipulator is also the safest choice for applications in which the roll must be picked up via a central shaft or mandrel.
Specific situations in which a roller manipulator is the preferred choice:
- Textile or fibrous rolls to which vacuum does not adhere reliably
- Rollers with a damaged or uneven surface
- Very heavy rolls (over 500 kg) that require extra stability
- Applications in which the roll must be picked up by the core, such as with coils or cable reels
- Environments with high levels of dust, grease, or moisture that make vacuum bonding difficult
In these cases, a roller manipulator offers greater mechanical reliability and a more stable grip, regardless of the surface condition of the material.
What are the ergonomic risks associated with manually moving rolls?
Manually moving rolls poses significant ergonomic risks. The combination of heavy weights, awkward dimensions, and poor body postures makes rolls one of the most physically demanding types of materials to handle manually. The most common injuries include back pain, shoulder and wrist pain, and muscle strains.
Specific risk factors associated with roll handling include:
- Weight and size: Rolls are often heavier than they look and offer little grip
- Rolling motion: A roller can roll away unexpectedly, posing a risk of falls and entrapment
- Uncomfortable working height: Lifting rolls off the ground or placing them in high positions requires extreme body postures
- Repetitive strain: at high frequencies, microtraumas accumulate, even in less physically demanding roles
Ergonomic handling of rolls begins with eliminating manual tasks. Even for rolls weighing 20 to 30 kg, a lifting aid is highly recommended when the task is repeated several times a day. A free workstation analysis can identify where the greatest risks lie in your specific situation.
What lifting capacity do I need for my rollers?
You can determine the required lifting capacity for your roll handling by using the maximum weight of the heaviest roll you regularly move as a basis. As a rule of thumb, the lifting device should have a capacity that is at least 20% higher than the maximum roll weight to allow for a safety margin and minimize wear and tear.
When determining the lifting capacity, also take the following factors into account:
- Weight class: Light rolls up to 100 kg, medium rolls up to 300 kg, and heavy rolls over 500 kg each require a different type of lifting aid
- Frequency: With intensive use, an undersized unit wears out faster and increases the risk of malfunctions
- Range of motion: if the roller also needs to be tilted or rotated, the mechanical load on the machine increases
- Future growth: Take into account the heavier loads you may need to handle in the future
A device with insufficient capacity is not only dangerous but also costly in the long run due to increased maintenance and premature replacement. Please refer to the product pages for an overview of available lifting capacities by product type.
