WHAT YOU NEED TO MAKE YOUR DOOR AND BUILDING A SAFE AND PERFECT FIT
STRESSES ON BUILDING - HYDRAULIC DOOR
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, this exerts forces to the building at the hinge line, also putting stress on the building and each side column where the cylinders 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!!!
SPEC 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® 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 bifold.
It's like a large airplane wing, the longer or further a
doorframe 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
Bifold doors fold in half when in the open position,
creating minimum forces to your buildings endwall.
Less stress on the building = Less stress on the door header.
Less stress on the doorframe = Less stress on the hinges.
