Hinge for heavy gates (upper+lower), D50.

Hinge for heavy gates, upper and lower, galvanized, O 50 mm

Product code: D4/52-D50

The D4/52-D50 hinge is a robust load-bearing element designed for strong and reliable attachment of heavy swing gates and massive steel structures. The set consists of an upper and a lower hinge, which together ensure stable positioning of the gate leaf and its smooth rotational movement when opening and closing.

Thanks to its robust steel construction, bearing support, and the possibility of adapting the mounting, the hinge is suitable for use in the production of new heavy gates well for modernizing existing gate systems. The design is engineered for high loads, with the manufacturer stating a gate weight Gmax/Goptimal of 400 kg.

Material

Steel with integrated bearing mechanism.

Surface finish

Zinc. The zinc surface finish provides steel parts with protection against corrosion and adverse weather conditions, contributing to a longer lifespan of the hinges in outdoor applications.

Mounting and compatibility

The hinges are designed for mechanical fastening to a support post or suitable steel structure using mounting plates with pre-drilled holes. The upper and lower hinges form a common fastening system that ensures the stability and correct guidance of the gate leaf.

The design allows for adaptation of the mounting according to the dimensions and arrangement of the gate. During installation, it is necessary to ensure precise coaxiality of both hinges, firm fastening, and correct load distribution. The bearing support helps reduce friction and ensures smooth movement even with a higher gate leaf weight.

The Gmax/Goptimal value stated by the manufacturer is 400 kg. When designing and installing, it is also necessary to consider the width and construction of the gate, the strength of the support post, the method of fastening, and the operational load.
