Rolls are everywhere in manufacturing: paper, plastic film and fabric rolls in printing and packaging plants, copper wire coils in motor winding shops, and narrow steel or aluminum coils in stamping and metalworking. Weights typically range from a few dozen kilograms to several hundred, and metal coils can reach about 1 ton.
The round shape is what makes rolls difficult: they roll away easily, the center of gravity shifts when tilted, and soft edges dent and damage the outer layers. The job is also more than lifting and setting down. Operators often need to upend a roll 90 degrees, slide it onto a machine shaft, or pull an air shaft out of the core. Doing this by hand or with a forklift is slow, risks pinched hands and back injuries, and often damages the product.
Before choosing the lifting equipment, choose how the roll will be held. FullSharp usually works with four tool types:
| Grip method | Suitable rolls | Advantages | Watch out for |
|---|---|---|---|
| Core gripper | Paper, film, fabric rolls with a core | No edge damage, easy 90-degree tilt | Core must be rigid and the right diameter |
| Outside clamp | Firm, tightly wound rolls | Fast pick-up, roll rotation | Not for soft rolls, surface may scratch |
| C-hook, dual-point hook | Cored rolls carried horizontally | Simple and low cost | Hook must be threaded, less suited to tilting |
| Vacuum pad | Steel and aluminum coils with sealed faces | No core contact, very fast | Surface must be airtight, assess first |

In printing, packaging and film plants, rolls are often stored upright on pallets but run horizontally on the machine. A roll tilting tool picks the roll from the pallet, turns it 90 degrees in the air and places it straight onto the machine shaft. Tilting can be manual or motorized for heavier rolls (FullSharp has built a motorized tilting tool for 250 kg rolls).
Once a roll is wound on an air shaft, pulling the long, heavy shaft out of the core is hard work too. A pneumatic manipulator or an electric articulating manipulator with a shaft gripper lets one operator withdraw the shaft smoothly while keeping it straight so the core is not damaged.
The roll tool has to hang from or mount on a load-carrying unit. Depending on the floor plan and duty cycle:
For heavy steel and aluminum coils, an electric vacuum lifting pad hung from a crane or hoist is a common choice.
Cored rolls are usually lifted with a core gripper hung from a manipulator, a jib crane or an overhead rail with an air balancer. To move rolls between the warehouse and several machines, use an electric lifter with a core gripper or outside roll clamp.
Yes, for tightly wound steel or aluminum coils with an airtight surface. Heavy coils use electric vacuum pads with a high-capacity AC pump, hung from a crane or hoist and used over short distances.
Use a roll tilting tool (manual or motorized) under a manipulator or crane, or an electric lifter with a 90-degree rotating head. The roll is turned in the air and placed straight onto the machine shaft.
A pneumatic manipulator or electric articulating manipulator with a shaft gripper supports the shaft weight and keeps it straight, so one operator can withdraw it without damaging the core.
