Hydraulic Door Installation

Hydraulic Door Installation

Hydraulic doors are engineered and factory produced to the specifications provided. When installed properly, they will open and close with ease and protect what’s inside. When installing the door, it’s essential to follow the instructions and ensure every step is completed properly. If steps are skipped or overlooked, the bifold door could potentially not work correctly or at all.

Keys to Installation Success

  • Plan Ahead
    Ensure you have the proper tools, equipment and labor to get the job done properly. Download the installation manual and specifications, and make a plan before getting to work.
  • Inspect and Verify
    Make sure your door opening is ready to accept your new hydraulic door. It must be square and plumb to prevent popping and other noises.
  • Pre-Load
    If installing your hydraulic door on a pre-engineered building, it’s important to know that these buildings are intended to have a dead load deflection but often do not come from the manufacturer loaded to that limit. Add hoists to the building and door to effectively dead load weight from the hangar to the metal building. This pre-loading will prevent sag and ‘smiling’ of the door in the open position.

Hydraulic doors are simple and strategic in nature. Take your time when installing it. Think ahead, be safe, and know your limits as an installer.

Hangar Doors is our passion…

For 39 years we have been leading the way and forging new territory.

Pre-Loading Example

This example shows a bifold door, but it is very similar to a hydraulic door. Two chain falls are strapped to the door frame and rated for 3 tons each.

Adding a portion of the door weight to the center of the building allows the bottom rollers to lay parallel to the columns and the door to roll straight up and down the column when opening and closing.
