Pivot hinges are unique hinges that are designed for doors that are undergoing heavy duties or doors that require special installation applications. For instance, you have a centre hung pivot hinge which helps you open up and close a heavy-duty door or any other access. Gravity pivot or double swing hinge allows a door to automatically shut itself behind whenever it is opened up. A double acting pivot hinge almost blends in and becomes invisible is used for door where you want neat finished products and a clear picture. These kinds of hinges are generally used in highly sophisticated places like saloons, offices and large companies and also massive workplaces where people prefer perfect architecture.
All the decorative part aside, when it comes to the study of the mechanisms of links and technical stuff for the hinges, it has been concluded that heavy duty pivot hinges are suitable for gates and vaults, that is, heavy duty and heavy load taking components. The explanation is as follows:
Pivot hinges are designed in such a manner that the pivot hinges can take in a rather greater deal of load impact on them unlike other normal hinges. When it comes to the normal hinges, they are made fragile and are not designed to take up as much load as the pivot hinges. Therefore, when you try and fix the normal hinges in place of pivot hinges, the normal hinge will not be able to keep up with the load that is acting on it. Internal stresses tend to develop in the hinges and s result they tend to break thereby damaging the hinge as well as the door. The pivot hinge unlike the normal hinge can take greater deal of load on it and tends to keep the door and frame intact and displaces the load through the desired angle.
Hence through this part of science, we can conclude that the pivot hinges are suited for use with gates and vaults as they are heavier compared to normal doors that are used inside the house.
