Vacuum lifters can simplify the handling of sheet metal by allowing operators to lift and move suitable sheets without manually supporting the full weight.

However, the vacuum lifter should be selected according to the actual sheet and working conditions.

1. Check the Sheet Material

Start by identifying the material being handled.

Common applications may involve steel plates, stainless steel sheets and other suitable metal sheets.

The surface condition is particularly important because the vacuum system needs to establish an effective seal.

2. Check the Sheet Dimensions

The length, width and thickness of the sheet affect the lifting configuration.

Large sheets may require multiple suction points to distribute the load more effectively.

The suction arrangement should be matched to the dimensions and shape of the workpiece.

3. Check the Weight

The maximum workpiece weight needs to be determined before selecting the equipment.

Do not select a vacuum lifter simply because its nominal capacity appears greater than the workpiece weight. The actual lifting configuration and working conditions also need to be evaluated.

4. Consider the Lifting Method

Ask how the sheet will be moved.

For example:

• From a storage area to a machine

• From a pallet to a workstation

• Into a laser cutting machine

• Between production processes

• From a horizontal position to another working position

Different handling processes may require different vacuum lifting configurations.

5. Consider the Installation

Some vacuum lifters are designed to work with overhead cranes or other lifting equipment.

The available crane, hoist, lifting height and working area should therefore be considered as part of the overall solution.

Conclusion

Selecting a sheet metal vacuum lifter starts with the workpiece rather than the machine.

Material, surface condition, dimensions, weight, lifting direction and working process should all be evaluated before choosing the appropriate vacuum lifting equipment.
