Design Criteria - Hydraulic

For the building Manufacturer, Contractor, Owner And Architect

What you need to make your hydraulic door and building a perfect fit

Schweiss Doors will work with you, your architects, contractors, or building supplier to ensure a smooth fit in your building. We supply hydraulic door weights, engineering data, windload specifications and design specifications to make certain that you have all the necessary information needed for the design of your building to accept the Schweiss hydraulic door of your choice. This information will insure a smooth and safe installation.

• The building header should be designed to accommodate horizontal and vertical building deflection to support the hydraulic door in all positions, with the proper lateral bracing.

• Schweiss provides the necessary detailed A-1 through A-6 spec sheets with each bid/order. The spec sheets should be read by anyone involved in the selection or purchase of the industrial hydraulic door of your choice.

• The hydraulic door should have solid footing / sill directly underneath the hydraulic doorframe and extend beyond the hydraulic doorframe outward from the hydraulic door to provide a base for the hydraulic door's base weather seal. This also prevent flow of water (into or under) the door installation.

• The finished floor should be designed to prevent flow of water into or under the hydraulic door installation. Sills should have a slight slope outward to prevent flow of water under the hydraulic door installation.


The hydraulic door can be designed with the same loading requirements for live, dead and windloads as the hangar building, to resist all anticipated loads with out sagging, bowing, or conflicting with its smooth and efficient operation.

• Your hydraulic door design can be approved and sealed by a professional engineer registered in the state where the project is located with the proper windloading and exposure.

• Windloaded hydraulic doors (to meet standard local codes).

• Extra heavy windloading requirements available.

• Wind pins are furnished on hydraulic doorframes to increase the windload strength and provide a sturdy installation.

• Wall pins are incorporated into the hydraulic doorframe to provide additional windload when needed.


Customer / electrician must:

• Provide proper voltage and electrical service to the door’s hydraulic power unit.

• Provide proper wire from the service panel to the up-down-stop switch on our hydraulic door.

• Provide proper circuit breaker in the service panel.

• Provide and install any electrical conduit.

• Electrical components placed on the door must meet the requirements of the N.E.C. section 513.

• Select the type of electrical service used to power the hydraulic door system.

• Final electrical hook up must be done by a licensed electrician.

Spec Sheets - Details

• The spec sheets pertaining to the details of your door are provided by Schweiss. We at the factory will help fill in the "Spec sheet details".


The customer and the building manufacturer are responsible to ensure that the building’s structural design is capable of handling all the imposed loads that the hydraulic door exerts on your hydraulic door header, end wall and building. Your hydraulic door exerts considerable horizontal loads on the building structure in the open position. We provide you with those loads that are applied to your building and hydraulic door. Your building header design must meet standard deflection and strength criteria, both in vertical and horizontal directions to support the door in all positions.


Improperly designed hydraulic door header can result in property damage, personal injury or death.
