Calculations



The rules of DIN EN 13155:2003+A1:2005 are to be applied for verifying the load bearing capacity of the vacuum lifting equipments. These include the following criteria:

  • Load bearing parts are to be measured and checked statically with 3 times the (nominal) load bearing capacity of the device.

  • Load bearing parts should not sustain any lasting deformations under a load of 2 times the (nominal) load bearing capacity of the device.

  • Vacuum lifters must be able to hold a load, in all positions at the end of the vacuum range, which is at least 2 times the (nominal) load bearing capacity of the device; these requirements apply for each vacuum circuit on dual circuit vacuum lifters.

In addition the combination of vacuum lifting device and suctioned load must, obviously, not exceed the load bearing capacity of the lifting equipment (crane / forklift).
