Weight Capacities for 3D Concealed Hinges
Thanks to our friends as BaSys, who make the PIVOTA 3D Concealed hinges, for providing this information
Note: always consult a PE to determine accurate door weights and to determine the correct 3D Concealed Hinge to use on your door
Introduction
Please note that the standard load values given in the catalogue relate to the application of 2 hinges per door (see also drawing below with regard to DIN 18101). Adding a third or forth hinge does not necessarily increase the load capacity of the door system.
Determining the Standard Load
The values given in the catalogue only apply to the types of rabbet shown in our drawings. Please note that these values may vary considerably with other rabbet types also possible. In this case, please contact us.

Besides, our statements are based on a dimensionally accurate and appropriate rabbet. The adjacent drawing shows the distance measures between the hinges according to DIN 18101 and the door dimensions used in our tests. We recommend not to exceed the table values because in practice loads may increase due to improper handling of the doors.
Attention: Load values and pull-out values must not be confounded. The load value indicates the emerging forces in practice while the pull-out value only indicates the tensile loading of a screwed pin in axial direction.
Please be aware that the term “standard load” does not necessarily reflect only the door leaf's weight. Oversizes (especially width of the leaf) and additional stress, e.g. the installation of a door closer, need to be well considered. The actual hinge norm DIN EN 1935:2002 states in this regard: “Door closers increase the load of the hinges and therefore also their usage. Door closers without opening suspension are considered to increase the effective door weight by 20%. For door closers with opening suspension this effect is much bigger and the effective door weight has to be increased by 75%. For this reason, it is recommended to use 3 or more hinges of grade 12, 13, or higher for doors which are equipped with door closers.

PIVOTA DX 300 3D | 661 lbs / 300 kg |
PIVOTA DXS 300 Steel 3D | 770 lbs / 350 kg |
Using a third or forth hinge can increase the load capacity of the concealed hinge system. Please contact us, we will evaluate the best possible configuration for your application.
