The engineering team at Schweiss Doors has developed an easy-to-grease hinge for hydraulic doors.
The new hinge design with grease zerks on every hinge allows users to easily 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. 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. The double push tubes provide extra support against forces imposed by hydraulic cylinders used to open and close the door.
