Others are saying the door comes with its own framework and does not hang on the building, can you explain this better?

Yes, the door may come with its own framework, but the framework is anchored to the buildings side columns and the buildings header. When you attach the door and the doors subframe to the building structure, now the door and subframe are relying on the building structure to support the door and the doors operation. When the door is in the fully open position it hangs way out there off the end of the building. Now the building structure is supporting the door, when the door is being opened the cylinders are putting forces to the cylinder brackets and the doors subframe that is attached to the vertical building columns. Note the cylinders are offset to the inside of the building columns that carry the loads of the door in all positions. Yes a sub-frame adds extra support, but every hydraulic door needs a building to hang off of and door columns to support the door and the powerful cylinders that raise and lower the door. All buildings must be designed to carry the weightloads and the doors operation to make a safe installation. This is how you avoid door failures/building failures.

When the door is fully open and I lower the door and stop the door at midpoint my building column bounces. What does this tell you?

The door column may be too light or the building column is not properly braced to take the forces of the hydraulic cylinders. Since the doors cylinder bracket is offset from the centerline of the door side column, that causes eccentric loading and torsion on the door side column. Correct the problem when you know this is happening.

We have a hydraulic door and are concerned about a door failure. What should we be looking for?

Raise the door to a half open position and jog the down switch several times so the door comes to a stop. Keep an eye on the top cylinder and cylinder bracket and watch for movement in the bracket. The bracket over time may fail if it was manufactured with too light a material. You must understand both cylinders carry the entire weight of the door.

There have been stories about hydraulic failures, can you explain?

When a hydraulic door has not been properly designed the top pivot points that the cylinder attach to can break off or fail. It's important to inspect each door and check for signs of failure. Also, Google the words "door failures" and read up on any problems that are published on the web.

What went wrong with the hydraulic doors?

Nothing went wrong with the hydraulic doors. When a door manufacturer has a poor cylinder bracket design and the building column and the subframe bracket are not properly designed, the forces the two powerful cylinders have on the building column will cause door failures. The stresses on a hydraulic door are much different than a bifold door. Hydraulic doors, when open, stick way out and are supported by two cylinders holding the door in all positions. Therefore, the cylinder bracket must be designed to carry those forces and transfer them to the building's door column. Knowing that, how can anyone tell you that the door puts NO stress on your building. Everyone is going to have to rethink that statement! Hydraulic doors are a great design, but must be done right. Understand the hydraulic door and its forces!
