Stacker coil lifting boom

Overview
An overview of industrial manipulators and dedicated gripping systems for coil handling, detailing solutions such as expanding mandrels, gooseneck grippers and controlled 90° rotation to enable safe, ergonomic and precise handling in production environments. Typical sectors: paper, plastics, packaging, converting, textiles and metalworking.

Why Is Coil Handling So Critical?
Coils present multiple handling challenges that affect safety and process efficiency:

• high weight
• large dimensions and bulk
• delicate surfaces that must be preserved
• frequent orientation changes
• precise positioning inside machines and on production lines

Poor handling increases downtime, operator fatigue and the risk of product damage.

The Advantages of an ATIS Coil Manipulator
An ATIS manipulator transfers load weight to the lifting system while allowing the operator to guide movements precisely. Key benefits include:

• reduced physical effort
• improved operational safety
• faster handling cycles
• higher positioning accuracy
• reduced damage to coil surfaces

Gripping Systems for Coil Handling
Selection of the correct gripping system is essential to ensure load stability and control throughout the handling process.

Expanding Mandrel Gripper
The expanding mandrel secures the coil via its inner core, providing stable retention. Recommended when:

• frequent handling is required
• high positioning accuracy is needed
• quick coil changes are necessary
• controlled rotation of the load is required

Gooseneck Gripper
The gooseneck gripper engages the coil through the central hole with a geometry that eases pick-up and positioning. It is suitable when it is necessary to:

• feed production machines
• handle stacked coils
• operate in confined spaces
• perform frequent format changes

90° Coil Rotation: Maximum Operational Flexibility
Processes often require changing coil orientation between horizontal and vertical. Manipulators with dedicated 90° rotation systems provide controlled movement while keeping full control of the load. Benefits include:

• increased safety
• reduced operating times
• more accurate positioning
• improved workstation ergonomics

Ergonomics and Safety
Assisted handling systems reduce physically demanding manual tasks, preventing fatigue and ergonomic risks. Safer handling results in:

• fewer operational interruptions
• greater production continuity
• improved operator well-being
• higher overall efficiency

How to Choose the Most Suitable Solution
Choice of manipulator depends on several critical parameters:

• coil weight
• inner and outer diameter
• rotation requirements
• cycle frequency
• available space
• required gripping method

An application analysis identifies the most efficient and cost-effective configuration.

Conclusions
Coil handling requires tailored solutions that combine lifting capability with safety, precision and efficiency. ATIS manipulators equipped with expanding mandrels, gooseneck grippers and 90° rotation systems help optimise handling, improve ergonomics and increase productivity.
