The new hinge design with grease points on every hinge segment enables owners - whether they be private individuals or commercial customers - to periodically grease their hinges from inside the doorframe without having to go through the cumbersome process of first removing the top rubber weather seal.
Hinge surface area is critical on large moving doors. Over the years, we all have heard of hinge failures on others doors. Large hydraulic cylinders are putting extreme forces on each of the outer hinges of the doorframe. Schweiss has designed and patented a robust hinge with more surface area to evenly distribute the loads of a moving one-piece doorframe. Look at the hinge surface area. The stresses on the very outer hinges are immense. With that being said, take one look at the patented Schweiss hinges and you'll clearly see the workmanship, strength and functionality of each hinge.
It's very important to be able to grease the door hinges with a heavy viscosity grease. When grease is used on the hinges of a large moving door it avoids unnecessary wear and adds longer life to the hinge and the doors operation. It's a common manufacturing practice to use grease on the critical wear points and load points to avoid unnecessary wear just like in the industrial equipment world with implements such as payloaders, skidloaders and other industrial equipment that are being operated around the clock.
Doors move and flex as they open and close. The forces on each hinge vary during operation.
