There's a Backup Within A Backup

Guess what - There's another backup on stand by! Grab a cordless drill and run the door up!

Scenario - 1

Let's say you go to raise your door in an emergency with the battery backup only to find out the battery is dead... Now what?

Scenario - 2

Highly unlikely. But for some reason the hydraulic gear pump motor took a puke.

Auxiliary Backup Pump

The Auxiliary pump in the tank will raise and lower the door with a handheld drill. If you arrive at your door and the battery is dead, now you have the option to use a cordless drill to open or close the door!

How Does This Work?

The DC motor has it's own stand-alone auxiliary hydraulic pump. On the top of the DC motor is a hex-head nut, use a cordless drill to open your door!

Hydraulic Doors By Schweiss

Schweiss hydraulic doors are custom made to fit any size opening for your building. Each door is built to fit your clear opening without using up existing headroom. There is no such thing as an odd size door or a job too small. You dream it, and we make your dreams come true.

Hydraulic Doors

Schweiss Doors is proud of its new hydraulic doors that swing outward. Already a leader in the bifold door industry, Schweiss Doors also now offers a better hydraulic door. The door design requires zero headroom, comes pre-hung, is watertight, easy to install, easy to operate with the push of a button, easy to insulate and swings out to provide a canopy when the door is in the open position.

Simple Unique Design

Powered by a powerful hydraulic pump, two heavy duty cylinders activate the hydraulic doorframe. Hinges across the top of the doorframe allow it to swing out and away from the building to the full open position. The hydraulic pump can be located away from the door opening to keep a clean look.

Safety Standards For Hydraulic Doors

Schweiss Takes Our Responsibility For The Customer's Safety Seriously.

As a door manufacturer, Schweiss has a responsibility to give the customer/users the safest hydraulic door possible... No Short-cuts!

Objectives

  • Ensure the safety and well-being of customers and users.
  • Minimize harm and reduce risks associated with hydraulic door failures.
  • Maintain regulatory compliance and manage safety risks.
  • Facilitate continuous improvement through incident analysis and corrective actions.
The repercussions of not having the proper safety features on your hydraulic door system are too great to be ignored.

Larger Cylinders With Spherical Bearings

“No one else in the industry offers this unique feature”
Only available on Schweiss Doors...

Schweiss heavy duty hydraulic cylinders have spherical bearings that keep equal pressure, stay straight, and have even forces in all positions

Doors Are Always Moving and Flexing

Spherical bearings reduce stress and wear on the cylinders, cylinders pins and clevishes during operation.

Hydraulic doors are large in size and just like an airplane wing, the doorframe flexes during operation. The hydraulic cylinders on each side of the doorway are connected to the doorframe and the building using spherical bearings. The spherical bearings accommodate the flexibility of the doorframe while at the same time allowing the cylinders to raise and lower the door without binding on the hydraulic cylinder pins and brackets. Spherical Bearings on both ends of the cylinder allow the cylinders to stay straight through the full range of motion.

Schweiss hydraulic cylinders have spherical bearings, which stay straight while still allows for flexing

Strong Words From Our Customer

“Soon as I saw and understood the spherical bearings design, it was a no brainer. I was immediately SOLD on the Schweiss Hydraulic Door!”

New Hinge Design...

"Our New Wrap-Around Hinge Design Sets The New Standard For Hydraulic Doors"

Schweiss doorframes are designed with double push tubes that are tied directly into the wrap-around hinges that connect both vertical push tubes directly to the header tube. The advantage of double push tubes is that forces of hydraulic cylinders are evenly distributed to the doorframe and the wrap-around hinges.

"There have been hydraulic doors with hinge welds that failed, literally tearing off the doorframe and destroying the door," Schweiss says. "Our design team provided a durable wrap-around hinge with grease zerks that are accessible without removing the top rubber seal."

Robust wrap-around hinges from Schweiss sell the door

Its Own Self-Supporting Subframe!

Schweiss engineered a new robust hinge design that distributes the door loads evenly across the self-supporting subframe, greatly reducing stress on the building structure.

Tubular self-supporting subrame and columns means every door greatly reduces stress on the building structure

The Hinges Sell The Schweiss Door

The Schweiss robust hinges are designed to withstand the door weights and hydraulic forces of the cylinders as the door opens.

Your door is only as good as its hinges! Take one look at the Schweiss hinges and you will clearly see the workmanship, strength and functionality of each hinge. The Schweiss hinges are big... strong... heavy-duty.

Grease Zerks

  • •  Schweiss hinges can be easily greased for longer hinge life.
  • •  SCHWEISS is the only manufacturer to offer hinges that can
       be greased from underneath the door without removing the
       top weather seal.

Removable Hinge Pins...

  • •  It's important to have removable hinge pins...
  • •  Hinge pins are not welded in solid on a Schweiss door.
  • •  Designed for easy maintenance.
  • •  All hinge pins are removable.

The hinge makes the door...

Hinge has to be strong as the door is in motion

The weight of the door and hydraulic forces exert loads on the hinge while the door is operating.

So it had better be STRONG!

The unique hinge design incorporates heavy hinge plates that wrap around each vertical push tube for added rigidity. Without this wrap-around design, the doorframe members can be overstressed and begin to tear apart from door weight and hydraulic forces over time. This won't happen with a Schweiss Door!

Hydraulic doors operate with one set of top hinges. These hinges need to be strong enough to support the door weight and the hydraulic cylinder forces when opening; unlike a bifold door that shares the load between the top hinges and the center hinges.

What Door Customers Are Saying...

  • “The hinges sold me.”
  • “The Schweiss team hit a home run by putting grease zerks in their hinges”
  • “Now that's a Serious Hinge, You guys have it figured out!”
  • “Oh my, nothing comes close to it. Professionally done!”
  • “Nothing on the market will even come close to the Schweiss hinge design.”

Customers Welcome Greasable Hinges

HINGE SURFACE AREA

Hinge surface area is critical on large moving doors. Over the years, we all have heard of hinge failures on others doors. Large hydraulic cylinders are putting extreme forces on each of the outer hinges of the doorframe. Schweiss has designed and patented a robust hinge with more surface area to evenly distribute the loads of a moving one-piece doorframe. Look at the hinge surface area. The stresses on the very outer hinges are immense. With that being said, take one look at the patented Schweiss hinges and you'll clearly see the workmanship, strength and functionality of each hinge.

GREASABLE HINGES

It's very important to be able to grease the door hinges with a heavy viscosity grease. When grease is used on the hinges of a large moving door it avoids unnecessary wear and adds longer life to the hinge and the doors operation. It's a common manufacturing practice to use grease on the critical wear points and load points to avoid unnecessary wear just like in the industrial equipment world with implements such as payloaders, skidloaders and other industrial equipment that are being operated around the clock.

The new hinge design with grease points on every hinge segment enables owners - whether they be private individuals or commercial customers - to periodically grease their hinges from inside the doorframe without having to go through the cumbersome process of first removing the top rubber weather seal.

Advantages of Grease

Using grease on the hinges is a better method of lubrication.

Using grease on the hinges is the industry standard.

Using grease on the hinges makes for a quiet door.

Using grease on the hinges makes for a smoother operating door.

Using grease on the hinges extends hinge life

Greasable hinges last forever.

Look at the Schweiss hinge, it has more lubricated surface area to give you longer life

Others rely on bushing FOR LUBRICATION

Doors move and flex as they open and close. The forces on each hinge vary during operation.

Not all bushings wear evenly.

Bushing wear thin over time.

Worn bushings offer less lubrication.

Less hinge surface area to distribute the door loads across the door header tube.

No way to inspect the bushings when the hinge pins are welded in - Not removeable.

Almost impossible to replace the bushings when the hinges pins are welded in solid.

All-Steel Doorframes

Schweiss uses all steel on their doorframes to avoid issues with wood cross members

Steel Horizontal Cross Members

Schweiss Manufactures All-Steel Hydraulic Door Frames

A 2x3-14 gauge steel member welded all around is good for about 120 PSF of wind. The steel is shop-welded, meaning no field labor is required. Every member of a Schweiss all-steel door is securely welded in place. Welds are strong and permanent and never need to be adjusted or tigthened.

Avoid Wood Horizontal Cross Members

As you open the door, it flexes due to the variable wind loads and its own weight. Tec screws or bolts in the end of a 2x4 are good for about 40 PSF of wind if the screws or bolts don't split the wod. Tec screws or bolts used to fasten horizontal wood cross members to the doorframe may work loose over time. Wood may shrink over time. The screws or bolts may shift in the horizontal wooded cross member, eventually working their way loose.

Schweiss Uses... Velocity Fuses In The Event Of A Hydraulic Hose Or Line Break

Designed to Lock & Hold The Door

The Door Must Stop Immediately! When A Hydraulic Hose/Line Break
On The Dead End of The Cylinder...

Velocity Fuses must lock the door in place to prevent it from coming down or falling on any machinery, airplanes, or worse yet, people.

Schweiss uses velocity fuses on their cylinders, which are designed to lock the door in place in the event of a failure for the best safety - shown in diagram

Some Others Use... Restrictors In The Event Of A Hydraulic Hose Or Line Break

Not Designed to Stop The Door

Restrictors Are Not A Safety Device When A Hydraulic Hose Or Line Breaks
On The Dead End Of The Cylinder...

Restrictors will not lock and hold the door open in any position. Hydraulic fluid will still shoot out of the damaged hose/line and the door will come down uncontrolled until it hits something or reaches the closed position.

Diagram demonistrating other door manufacturers utilizing restrictors on their doors, which do not stop the door in event of a failure - shown in diagram

Velocity Fuses Lock The Door In Place

Velocity Fuses... have a preset flow rate and automatically
lock if that flow rate is exceeded. This keeps the door from falling
in the event of a hose or line break!

  • Velocity Fuse . . .Keeps the door from falling in the
    event of a hose/line breaking!
  • Velocity Fuse . . . Stops the flow of oil and holds
    the door in place.
  • Velocity Fuse . . . Precisely sized for each door to lock up
    and stop the door     from falling.
  • Velocity Fuse . . . When used alone on the load side of the
    hydraulic cylinder, prevents the door
    from falling onto machinery, planes,
    vehicles or people below.
  • Velocity Fuse . . . Stops movement of the door in the event
    of a hose or line breaking on the dead
    end of the cylinder which prevents the
    door from coming down uncontrollably.
  • Velocity Fuse . . . When used alone on the dead end of the
    hydraulic cylinder, locks and holds the
    door in an open position     in the event of
    a hose or line breaking and prevents the
    door from falling.
  • Velocity Fuse . . . Are precisely sized and designed to lock
    and hold the door in any position     in the
    event of a hose or line breaking!
  • Velocity Fuse . . . Are designed to lock and hold the door
    load. An important locking safety
    feature. A Must Have!

No Hydraulic Door Should Be Without A Velocity Fuse

Restrictors Do Not Lock The Door In Place

Restrictors... are an orifice and are not a safety valve.
They will not keep the door from falling in the event of a hose
or line breaking!

  • Restrictors . . . Will not keep the door from falling
    in the event of a hose/line breaking!
  • Restrictors . . . Restrict or limit the flow of oil but
    will not stop the door from falling.
  • Restrictors . . . With a precisely sized hole that creates a
    pressure drop / restricts the flow but
    will not stop the door from falling.
  • Restrictors . . . When used alone on the load side of
    the hydraulic cylinder it is like a
    non-adjustable needle valve that
    restricts or limits the flow of oil but
    will not stop the door from falling.
  • Restrictors . . . Slow down movement of the door in
    the event of a hose or line breaking
    on the dead end of the cylinder but
    will not stop the door from falling.
  • Restrictors . . . When used alone on the dead end of
    the hydraulic cylinder will not hold
    the door in an open position     in the
    event of a hose or line breaking and

    uncontrollably     in the event of a hose
    or line breaking!

Restrictors Are Not A Safety Device

Ask yourself... “What's The Safest Option?”

Ask yourself... “Is There A Better Way?”

When Others Use Restrictors

When here is a hydraulic hose/line failure on the dead end of a cylinder...

Diagram demonstating what happens when a hydraulic hose or line fails on hydraulic door that uses restrictors instead of Schweiss velocity fuses - the door is coming down!

WARNING

When others are using restrictors in the
dead end of the cylinder as a safety device...

  • They may be setting you up for slow
    motion disaster, Your worst nightmare!

Worst Case Scenario...

To have a door come down on a million dollar plane
or even worse than that, have the door come down
on people and put lives at risk!

Be careful... when phrases like these are being used to explain what happens in the event of a hydraulic hose/line failure using restrictors.

  • “Gently coming all the way down...”
  • “Controlled rate of descent...”
  • “Coasting down...”
  • “Preventing the door from slamming down...”

Some Have Said:

“In the event of a hose or line breaking, it will not stop the door from falling.
It takes 7 seconds for a door to come down when a hose / line breaks.”

Fact Is... That's Not A Lot of Time!

The door is coming down with no safety built-in to stop the door. Better clear the area!

When manufacturers use Restrictors on their cylinders...

  • No safety built-in.
  • Restrictors are not load holding.
  • No way of stopping the door from coming down.
  • Slow motion distaster... Your worst nightmare!
  • The door won't stop if a hose/line fails (on the dead end).
  • Door will come down if there's a failure, no matter what.
  • The door is coming down on whatever is underneath it.
  • Slowing the door as it comes down isn't good enough.

Did You Know?

If the manufacturer uses restrictors on the dead end of the cylinders, neither the restrictors nor the photo eyes will stop the door. You can't rely on the photo eyes to stop the door if a hose/line breaks on the dead end of the cylinder.

The Door Is Coming Down...

How safe can it be when the door doesn't stop during failures? The truth is IT'S NOT!

Restrictors Are Not A Safety Device!

Find out what safety devices you're getting on the hydraulic cylinders when you order your hydraulic door.

Call Schweiss

Ask yourself...“Do I know what I'm getting?”

“Is Safety Important To Me?”

You should be asking if hydraulic doors have restrictors or velocity fuses, and ask how you go about getting velocity fuses installed on your door to make it safer!
