Schweiss Robust Hinges
Hinge design is extremely important to a durable hydraulic door because the hinges bear a heavy load when the door is moving.
Schweiss Hydraulic doors only have one top set of hinges. These hinges need to be strong enough to support the door weight and cylinder forces while moving. The unique hinge design incorporates heavy hinge plates that wrap around each vertical push tube for added strength and rigidity when opening and lifting the large hydraulic door.
Schweiss uses double push tubes that are tied directly into the wrap-around hinges, which connect both vertical push tubes directly to the header tube. This provides you the advantage of having the forces of hydraulic cylinders being evenly distributed to the doorframe and the wrap-around hinges. This makes the door much more reliable and reduces the risk of your door being torn off from the doorframe due to uneven distribution.
Schweiss Hydraulic Doors are large, so you need a strong hinge to handle them effectively. Every Schweiss hydraulic door has a self-supporting subframe that distributes the door load evenly across the frame. Not only does this reduce stress on your door, but it is also much better for your building. When it comes to creating frames that are bigger, stronger, heavier, and just better overall, Schweiss hydraulic hinges are the only answer.
“THE HINGE MAKES THE DOOR”
Since doors are always moving and flexing, using spherical bearings can reduce the stress and wear on the cylinders, cylinder pins, and clevises during operation of the door.
Schweiss Hydraulic doors are larger than regular doors, which means that the hydraulic door frame will flex more during operation than a regular door would. By using spherical bearings, Schweiss is able to accommodate the flexibility of the hydraulic doorframe and let the cylinders raise and lower the door without binding on the hydraulic cylinder pins and brackets. This feature is only available on Schweiss Hydraulic Doors, so take advantage today!
Removable Hinge Pins
- A wrap-around design evenly distributes the weight of the door to the hinges and door frame while opening and lifting the door.
- Uses heavy duty hinges with no bushings to wear thin.
- Removable hinge pins are easy to maintain; welded in pins cannot be greased.
- Grease extends the life of the hinges and the door.
