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.
