  • Lift HC Full Mortise

    Mechanical Lift Hinge Kits for doors weighing up to 3000 lbs

    Description:
    For use on large acoustical doors that require enhanced sealing characteristics by compressing the seal against the frame and threshold. The Lifting action provides ½" rise in 180 degrees of door rotation via a unique high lead power screw and nut design that will take higher loads, wear less and operate easier than conventional cam-lift hinges. All wear surfaces are lubricated and sealed from the environment. Can also be used in self-closing applications where the minimum door weight is 150 lbs.

    A (3)* hinge kit comprised of: (1) LIFTU hinge located at the center of the door that supports the weight and provides the lifting action; (2) Series W radial support hinges, properly spaced take the radial load. Refer to the Engineering Section on how to calculate radial load based on hinge spacing or contact the Engineering Department.

    Specifications:
    Hinge Size: 5.00" high x 6.53"(Ref.) Full Surface
    5.00" high x 6.75"(Ref.) Full Mortise
    Vertical Capacity: 3000 lbs
    Radial Capacities: 400 lbs, 1200 lbs
    Vertical adjustment: (+/-) 1/8"
    Approximate torque to move door: 0.23 lb-in/lb
    Bolted connection: ½" diameter hex head(not supplied), Fu= 120,000 min; preload = 625 lb-in
    Welded connection: ¼" fillet weld, (3) sides each leaf, 225° F weld interpass temperature at barrel
    Base Material: 1018 Cold rolled steel, options: 304 SST, 316 SST
    Finish: USP (primed), options: zinc clear, US32D
    *a (2) hinge kit consisting of (1) LIFTU and (1) Series W radial support hinge can be used as long as the applied radial load is less than or equal to 200 lbs.

  • Spring Lift

    One Kit is comprised of a single Spring-Lift 100 Hinge installed as the center hinge that raises the door while opening. In addition, this hinge is furnished with a set screw for adjusting the spring closing force. Two W-100HD modified hinges installed at the top and bottom of the door support the radial (horizontal) loads generated by the moment arm of any wide door or gate.

    Description:

    The center Spring-Lift 100 Hinge supports the full door weight and will raise the door ½" in 180 degrees. The lifting action provides the hinge with 2 force components for generating positive self-closing action:

    (1) The potential energy created by raising the total weight of the door with the hinge’s internal power screw.

    (2) As the door is opened, a series of disc springs are compressed that will add to the total potential energy in the Spring-Lift 100 Hinge. A set of disc springs, located inside the top of the hinge, that when adjusted with the large set screw controls the amount of closing force acting on the door. Turning the 1"- 8 set screw clockwise, will decrease the closing force and minimize door slamming. Turning the set screw counterclockwise will increase the closing force if the door needs to overcome wind loads or out -of -plum conditions. Note: The adjusting set screw is a force balance and not a damping devise; therefore, changing the amount the door is opened and/or varying other field conditions may affect how the door contacts the frame. We strongly recommend that a latching devise be incorporated into the design of the door/gate. The small set screw at the bottom of the hinge adjusts the height of the door (+/- 1/8") for fine tuning alignment with the strike edge.

    The (2) outer hinges (top and bottom) are modified from the Series W-100HD hinge and provide only radial (horizontal) support and are designed to allow for vertical movement. These hinges can support doors or gates of any width providing the applied radial load does not exceed the radial capacities. Refer to the Engineering Section for radial load calculations.

    Capacities:

    Door weight = 1500 lbs
    Radial = 1630 lbs

    Specifications

    Series Spring-Lift 100 Hinge Kit will function at the rated capacities providing the following specifications are met:

    The 3 hinge system is installed without inducing "hinge bind".

    Door weight shall never exceed the capacity of the center hinge.

    The applied radial load shall never exceed the radial capacity of the top and bottom hinges.

    Bolting:
    5/8" diameter Grade 5
    Fu = 120,000 psi
    Preload = 1200 lb-in
    Minimum thread engagement into reinforcing member shall be equal to bolt diameter.
