HECTOR, Minn. – Schweiss Doors has developed an easy-to-grease hinge for its hydraulic doors.
The new design with grease zerks on every hinge allows users to grease hinges from the underside of the doorframe without having to remove the top rubber weatherseal.
The wrap-around hinge brackets connect directly to the vertical push tubes for added strength, according to company officials.
Schweiss Doors doorframes are designed with double push tubes directly to the header tube. The advantage of double push tubes is that forces of the hydraulic cylinders are evenly distributed to the doorframe and the new wrap-around hinges, company officials explained. The double push tubes provide extra support against forces imposed by hydraulic cylinders used to open and close the door.
Schweiss Doors also has incorporated “spherical” bearings in all of its hydraulic one-piece doors. Spherical bearings are located at each end of the door’s power cylinders. Spherical bearings are critical to the safe and smooth operation of a hydraulic door, extending the life of the door, according to Schweiss officials.
The company also introduced new insulated panels. The lightweight interior panels feature interlocking edges that fasten to the exterior of the doorframe, reducing installation time, while adding R-value and providing a fully insulated thermal barrier.
Paul, what do you mean by a higher power door?

Here’s what I know about Schweiss doors … they are the best and the customer support is awesome. I own a 44′ x 12’+ bifold door installed in 2002 and have had no trouble with it. A minor problem just after installation was immediately rectified and if I ever build another hangar, it’ll have a Schweiss door. Mine has the straps and autolocks and I’ve never even had to adjust it. My location is too cold for a hydraulically operating door so the strap lift system is best for me.
I use Corrosion X as the lubricant because it works it’s way into everything over time.
Keep life simple and buy a higher power door instead. It doesn’t have any hinges so you can forget about lube.
Excellent idea! I have a Hydroswing door that I annually clime up on a latter and oil the hinges from the inside of the hangar and outside and am not really sure if I am helping or not. Any one out there with a solution to this problem with the same type (Hydro swing) doors?
