Precisely engineered neat, cellar design

One-Piece Door Frame

Any Size Door

• There is no such thing as an odd size. All doors are custom made for your opening. Schweiss is
always willing to make changes that help the customer fulfill his door needs.

About the Frame

Pre-assembled, pre-welded and pre-hung to help reduce loads on your building:

• One piece frame work manufactured with 2 x 4 tube.
• Comes complete with its own framework and pre-mounted hinges.
• Continuous header tube, extra supporting frame.
• Bolted frame connections for shipping no welding easy to install.
All Schweiss hydraulic doors are factory welded and made of structural steel tubing. The doors are
hinged horizontally at the top of the frame using heavy duty hinges by each upright tube on the door
frame, which evenly distributes the load onto your door, building, truss and header. Hinges are factory
pre-located to align with the building and truss members. The door swings outward, away from the
building. In the open position, the door will be laying flat at 90I. Doors are trussed to provide extra
strength. Extra metal in the right place reduces the bowing or sagging when the door is open or closed.
Each door is fully assembled from the factory, saving you hours of installation time.

Heavy duty door trusses

All of our doors are manufactured with webbed trusses to provide extra strength. The truss is located
near the very bottom of the door across the entire width of the door frame. We have two styles of trusses.
External Webbed Truss - Standard - Style One
   • Placed on the outside of door frame.
   • Visible from the outside of the door/ building.
   • Lose No Headroom.
   Covered External Truss
      • Keeps debris and snow from collecting under truss
   Raised External Truss
      • Optional A raised external truss off the finished floor gives you the advantages
Internal Truss - Optional - Style Two
   • Placed on the inside of door frame. Nice clean look.
   • Cannot be seen from the outside of the door / building.
   • Weather elements are not a problem.
   • Additional headroom required with this style.

Hydraulic Door Feature

Heavy Duty Hinges

Hinges are mounted on a self-supporting, pre-mounted, continuous header tube. All hinges are
self-contained on the door frame which makes the door easy to install. Hinge pins are 1" diameter
attached to 3/8" thick hinge plates.

Lift points - 2 hydraulic cylinders

Hydraulic doors are opened with two hydraulic cylinders. Located on each end of the door. Schweiss
provides extra heavy duty cylinders that will give you many trouble free years of operation.

Heavy duty cylinders... like no other

• Heavy duty cylinders and components used on each side of the doorway.
• Internal cylinder stops keep the door from overextending, adding strength and safety
• Velocity Fuse for free fall protection. Very Important! We include it. The velocity fuse eliminates the
   risk of unplanned closure in the event of a hose or a line breaking. An important safety feature.

Automatic Latching... Self Latching and Holds the Door in Place

• Hydraulic cylinders automatically pull the doors in tight against your building and will keep the door
    in a locked position to providing a tight seal.
• Push a button to automatically lock and unlock the door to the closed position.
• The hydraulic pump has a built-in positive hold valve that maintains and keeps the door locked in the
    closed position which provides a constant weather tight seal.

Vertical cylinder leg brackets & self-supporting header tube

• The Vertical cylinder leg is the self contained framing that the hydraulic cylinders attach to.
• The Vertical cylinder legs attach to the building's side columns and help support our door in all
    positions.
• Schweiss offers custom vertical cylinder legs in situations where additional strength is needed.
