Product Family Stainless Steel Quality Class 2

The Ganter product range includes a large number of standard parts made of high-quality, non-rusting stainless steels. Thanks to their outstanding material properties, these are used in a wide array of industries. Their corrosion and rust resistance in particular contributes to the value stability and longevity of machines and equipment.

For easier differentiation, the stainless steels used by Ganter are divided into stainless steel quality classes:

Edelstahl Güteklasse 1 Stainless Steel Quality Class 1

Edelstahl Güteklasse 2 Stainless Steel Quality Class 2

Edelstahl Güteklasse 4 Stainless Steel Quality Class 4

Product description

Multiple-joint hinges GN 7237 are installed on the inside of flaps, hatches and doors to save space and ensure protection against vandalism. The hinges have a maximum opening angle of 180°, which provides optimal accessibility and avoids the blocking of escape routes by open doors, for example.

Use of this hinge type leaves housing exteriors free of attachments that do not match the design or that should be avoided entirely in the interests of fast and easy cleaning.

Multiple-joint hinges are generally used in pairs, meaning that one L type and one R type are used per opening. For higher loads, e.g. from large hatches, these can be supplemented with additional hinges of any type.

Installation position - pivot characteristics

The multiple-joint hinges can be installed on the housing with the slots of the fixing angle piece oriented either perpendicular or parallel to the hinge axis. This results in the two pivot characteristics depicted.

Adjustment and fastening options

e209805a-b069-4ac0-9ab3-092cd7093ccc

The multiple-joint hinges can be adjusted in three planes during installation. For example, this allows tolerances to be adjusted or the required compressive forces for seals to be established. Two planes can be adjusted via the parallel or perpendicular slots in the fixing angle pieces. In the third plane, position corrections can be made using the spacer plates GN 2370.
Plates with tapped holes GN 2372 as well as plates with threaded studs GN 2376 are also available for fastening the hinges. The latter can be welded on or inserted through the wall from the outside and fastened in place. All accessory items are designed for use with both fixing angle pieces.

Design variants

Flaps, hatches and doors can be inset, flush or mitered. The maximum wall thicknesses and bend sizes for sheet metal constructions given below arise from the respective installation type.

6023451 ... ∞252121

The design variants shown represent standard installation conditions. If the installation position of the hinge is changed or one of the two wall thickness dimensions is lower than s or b, the maximum achievable dimensions change independently of each other. This makes it possible in some cases to work with larger wall thickness dimensions than those specified with the same hinge size. A simple design check via CAD or a test setup is therefore recommended.

Load capacity

The maximum load of the multiple-joint hinge specified below applies to the standard use cases and serves for orientation in the case of deviating applications. The resulting forces lead to slight elastic deformation, which can be compensated for by means of the adjustment options, if necessary.
