Strongest Doorframe on the Market!
No Wood used on Schweiss Doors!
Schweiss doorframes are designed with double or triple push tubes that are tied directly into the wraparound hinges that connect both vertical push tubes directly to the header tube. The advantage of double push tubes is that forces of hydraulic cylinders are evenly distributed to the doorframe and the wraparound hinges.
"There have been hydraulic doors with hinge welds that failed, literally tearing off the doorframe and destroying the door," Schweiss says. "Our design team provided a more durable wraparound hinge with grease zerks that are accessible without removing the top rubber seal."
