HydroTilt

21st HydroTilt doors are one piece upward acting doors which range in available sizes up to 80’ in width and 24’ in height. The 21st HydroTilt has distinct design advantages over any other large door available today.

Operated by a single hydraulic cylinder, the inherent design insures the door is always coordinated in its upward and downward movement. Many competing designs have issues with uneven travel of each side of the door as it opens and closes.

Duel safety features insure failsafe drop protection.

Frame and header systems provided with the 21st HydroTilt door support 90% of the door’s weight and allow for substantial building cost reductions over buildings designed to accept BiFold doors.

21st HydroTilt doors allow buildings to have lower eave heights, since less headroom above the opening height is required than for BiFold doors, thus reducing building costs.

21st HydroTilt doors are mechanically self-locking with no moving lock parts. The self-locks engage the header across the top of the door, the slab across the bottom of the door, and the side frame vertically on rack side.

Positive and negative wind loads exerted on the 21st HydroTilt are transferred to the building and slab through the mechanical self-lock system.

Approximately 7’ of the 21st HydroTilt door remains inside the building horizontally when fully open. The balance of the door is outside the building when open, where it provides a canopy.

A truss generally located 6’ beneath the opening height, spans the doors horizontally. The truss provides rigidity and wind load capability to the door. Using our unique travel geometry allows for the truss to be stored inside the building when the door is in the open position. Having the truss inside the building insures no water infiltration into the door when rain is received while the door is open. Many competitors have water infiltration issues that are very difficult to overcome since their truss is outside when the door is open, exposing cladding joints which are difficult to keep sealed.

Walk through pedestrian doors (pass door) are well suited to the structure of the HydroTilt door since the truss is above the pass door frame. Additionally, ADA compliant installations are available.

The 21st HydroTilt is designed to limit the number of parts required to make the door. This reduces the complexity of manufacturing, inventory, assembly, and installation. The HydroTilt requires no welding during installation. It is packaged knocked down for shipping, much like the building it is installed into. Many doors will ship in one crate by conventional LTL freight carriers thus significantly reducing freight costs and unloading complexity. Generally one forklift is all that’s required. Very large welded door halves that are hard to unload, move, align, and splice together are a thing of the past.


Tilt-Over Explained & Options

With a Tilt-Over Hangar Door, instead of panels sliding to the right or left, a large single panel the full size of the opening lifts vertically and then “tilts” and rotates about a central pivot location. This motion projects part of the door toward the outside and the other half inside the building as it goes up. In the up position, the door provides a shade canopy and a slight slope towards the exterior to drain water away from the hangar. The door has an initial vertical lift so operation in environments where snow obstructs movement away from the building is not affected. The panel is lifted by thick and sturdy cable normally used on cranes. The Tilt-Over door may be lifted by various methods of transmission including spring counterbalance and hydraulic actuation. Remote control operation of door (open/close) is an option. Certain sizes of this door are stocked in-house at Alamo Door Systems causing the lead times to be surprisingly short. Installation is a breeze thanks to our installation manual (downloaded through “Architects Tools & Resources”) and step-by-step installation video (coming soon).

Options

  • Framed and clad with a wide variety of materials, including insulated cladding
  • Windows, walk doors, or unusual aesthetic features
  • Manual or remote operation
  • Light or Heavy-duty weather seal

Benefits of the Alamo Door Systems Tilt-Over Door!

Tilt-Over doors exert very little reaction forces on the building itself due to the balanced design and additional door frame structure. Instead of relying on the strength of existing building structures to transfer the load, we engineered our own frame to receive the load from static and dynamic operation of our door which, in turn, transfers a reduced distributed load to the building. Other benefits of this style door is the incorporation of many safety features NOT included in other style doors to protect you and your property in the case of some “Act of God” situation. One such feature is our “all-in-one” lift-and-locking joint, patented by Alamo Door Systems, which lifts the door while serving as a safety measure if tension in the cable ceases to exist then the locking mechanism locks into the frame and the door is held in place.

Benefits

  • Nearly Non-Existent Reaction Forces Exerted on Building
  • All-in-One Patented Lift-and-Locking Joint for Safer Lifting Experience
  • One Hydraulic Cylinder for Uniform Pressure Lifting and Reduced Cost
  • Telescoping Guide Arms for Quiet, Friction-less Tilt-Over Action
  • Extensive and Effective Sealing System to Keep Your Hangar Protected from the Elements
  • Very Little Side or Head Room Required
