Stresses on the building - hydraulic forces
ONE-PIECE® HYDRAULIC
WHAT YOU NEED TO MAKE YOUR DOOR AND BUILDING A SAFE AND PERFECT FIT
IMPORTANT:
Stress On Building --- Hydraulic "One Piece"
• The door is a large moving piece of equipment THAT ATTACHES TO YOUR BUILDING and exerts outward
and inward forces
• One Piece doors cantilever out from your building, exerting forces when in the open position.
Door Reactions While Opening And when In the Open Position.
• When your hydraulic door is opening or is in the wide open position, the exerts forces to the building at the
hinge line, also putting stress on the building and each side column where the cylinder attach.
The Building Manufacturer / Contractor / Owner is Responsible to Ensure:
• That the Building's structural design is capable of handling all the Imposed loads that the door exerts to your
door header, side door columns, endwall and building.
• Your building header/column design must meet standard deflection and strength criteria, both in vertical and
horizontal directions to support the Hydraulic door in all positions.
• All materials not supplied by Schweiss, are the full responsibility of others!!!
Specs Sheet Data: Included with Each Door Sale
• Schweiss provides the necessary detailed A-1 through A-6 spec sheets with each bid / order, showing all the
door forces to your building. The spec sheets should be read by anyone involved in the selection or purchase
of the industrial door of your choice.
Cautions and Myths That Can't Be Ignored
• Building does not have to be made stronger.
• Building does not have to be modified to hold a hydraulic door.
• Building does not have to be engineered with extra reinforcing to accept a Hydraulic Door.
• Door does not hang on your building...What does the door & frame attach to?
ONE-PIECE® HYDRAULIC
FAST-MOVING BI-FOLD
(extends out 1/2 the distance)
One Piece® Hydraulic Door
Bi-Fold Door
One-Piece® doors cantilever out from your building,
exerting additional forces on building header when in
the open position. A One-Piece® door hangs out
twice as far from the building as a bi-fold.
Results:
It's like a large airplane wing, the longer or further a
door frame sticks out away from the building at a 90°
position, the more torque / stresses it adds to the
building header. The building header must be
prepared to support the forces of your door in all
positions.
Bi-fold doors fold in half when in the open position,
creating minimum forces to you buildings endwall.
• Less stress on the building
= Less stress on the door header.
• Less stress on the door frame
= Less stress on the hinges.
