From the minute you press the control button or your handy remote control, you'll be amazed at how this door functions. It's everything you want it to be and more.
The unit has all the bells and whistles and comes with single or 3-phase electrical components. Easy to read psi pressure gauge, service filter and fluid temp gauges let you know that the door is always working properly and at full capacity. Everything is in one compact hydraulic pump unit powered by 2, 3, 5 or 10 horsepower motors to safely lift even the smallest or heaviest doors and seal them tightly.
Schweiss Safety Advantages allow the door to lock up and down or safely lower or raise your door in case of electrical failure. Each unit comes with a standard tractor hydraulic hookup, lower the door at any time, very handy for agricultural or industrial applications. Specially designed built-in manual override allows the operator to lower the door in case of a power outage. Battery backup features which use a DC battery or drill to operate the door in either direction in case of an emergency, giving you a superior backup system for your door and peace of mind.
They're Powerful... We're talking THE most efficient pumps with standard motors designed ready to lift any size door, at any time, all the time!
Over the years Schweiss factory engineers rolled together customer comments, combined with high-tech design knowledge and experience to come out with perfection! Perfection in a compact pump unit ready to be mounted anywhere you want it.
Spherical bearings reduce stress and wear on the cylinders, cylinders pins and clevises during operation
"No one else in the industry offers this unique feature" only available on Schweiss Doors...
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.
"Soon as I saw and understood the spherical bearings design it was
a no brainer. I was immediately SOLD on the Schweiss Hydraulic Door!"
Schweiss doors are extremely weathertight and designed so the doorframes overlap by two inches on each side column making it easy to seal on the sides of the doorframe. The two hydraulic cylinders pull and power the doorframe securely and seal against the door columns!
•Faster Opening Speeds
•Less Headroom Required
•Quiet, Smooth Operation
•Easy to Install
•Bigger, Better Cylinders
•Low Maintenance Components
•Less Moving Parts
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 tightened.
As you open the door, it flexes due to the variable wind load 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 wood. 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 the horizontal wooden cross member, eventually working their way loose.
Schweiss doorframes are designed with triple push tubes that are tied directly into the wrap-around hinges that connect each vertical push tube directly to the header tube. The advantage of triple push tubes is that forces of hydraulic cylinders are evenly distributed to the doorframe and the wrap-around hinges.
This Schweiss hydraulic door was equipped with a hydraulic 2-speed valve for smooth operation that includes a 12 volt backup system in case of a power outage. The door has the newly designed and patented wrap around hinges that can be lubricated from inside the building, making maintenance quick and easy!
Schweiss is the only manufacturer to offer hinges that can be greased from underneath the door without removing the top weather seal.
Hinges can be greased
from underneath the door
Others try to get by
using bushings and
welding the hinge pins
in place . . . Not the Schweiss way!
"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."
Schweiss hydraulic cylinders exerts a direct force on the doorframe and hinges as the door opens and closes. It's important to have robust hinges to withstand all the forces as the door opens and closes... The hinges on the door are as important as the door frame itself.
It's all about surface area. The more surface area you have in the hinge design, the lower the stresses will be in all the components. The Schweiss hinge design has 22" of surface area that will give you years of service no matter what size 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.
The door weight and hydraulic forces pull down on hinge when door is opening
While other doors may
appear to be the same on
the surface, there is really . . .
no comparison !
The Schweiss hinge design is superior. The Schweiss design, with the extra long pin, not only reduces the stresses in all the components of the hinge, but also spreads the forces evenly across the doorframe. The Schweiss design is robust!
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 points that are accessible without removing the top rubber seal."
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.
The door will not stop if a hydraulic component fails.
The door is coming down on whatever is underneath it.
Slowing the door as it comes down isn't good enough.
Stops the door immediately! Standard from Schweiss.
Building costs are significantly reduced with our Tri-pod leg design self-supported hydraulic doorframe.
Schweiss is the leader in manufacturing hangar doors for general aviation and commercial jet hangars. Our self-supported hydraulic door is designed with a purpose and a clear objective. The self-supported design will benefit everybody from architects, engineers to building manufacturers, and more importantly will save money for the end-users of the doors.
