Pneumatic assistive manipulators use compressed air to provide lifting and movement assistance for industrial workpieces.

They can be a practical choice for manufacturing environments where pneumatic power is already available and operators need assistance with repetitive handling tasks.

1. Determine the Workpiece Weight

Start with the maximum weight of the workpiece.

The total handling load should also include the weight of the gripping tool or other attachment connected to the manipulator.

Selecting the equipment according to the maximum actual load provides a better basis for equipment configuration.

2. Check the Workpiece Shape

The shape of the workpiece affects how it should be supported.

Large, irregular or awkward components may require specialized tooling to maintain stable control during movement.

The gripping method should also allow the operator to access the workpiece and complete the required task.

3. Define the Required Movement

Consider how the operator needs to move the workpiece.

The application may require:

• Vertical lifting

• Horizontal movement

• Rotation

• Tilting

• Positioning

• Movement between workstations

The required movement helps determine the manipulator structure and tooling.

4. Check the Working Range

The manipulator needs to reach all required positions.

Consider the lifting height, horizontal reach and available operating area.

The working range should also take nearby machines, fixtures and other equipment into account.

5. Check the Pneumatic Supply

Because the manipulator uses compressed air, the available pneumatic supply should be evaluated.

Air pressure, air consumption and operating conditions need to be compatible with the selected equipment.

6. Select the Right Tooling

The manipulator itself is only part of the handling system.

Depending on the workpiece, the end tooling may use:

• Mechanical gripping

• Hooks

• Vacuum lifting

• Clamping devices

• Application-specific tooling

The tooling should match the material, shape and handling requirements of the workpiece.

When Is a Pneumatic Manipulator a Good Choice?

A pneumatic assistive manipulator can be considered when:

• Compressed air is readily available

• Operators need lifting assistance

• The same handling task is repeated frequently

• Manual handling creates excessive physical effort

• The workpiece requires operator-controlled positioning

Conclusion

Choosing a pneumatic assistive manipulator starts with the workpiece and the handling task.

Load, shape, required movement, working range, pneumatic supply and tooling should all be considered together to determine a suitable configuration.
