WITH SCHWEISS
HYDRAULIC
DOORS
DOORS, AS you know, come in many sizes, shapes
and styles. Schweiss has been in the business for
over 40 years delivering its brand-name line of
hydraulic and bifold liftstrap doors all over the
world. Some of these custom-made doors are small,
but then there are also BIG, BIG doors.
A prime example of this is a 115 ft.
wide x 23 ft. Schweiss custom-made
hydraulic one-piece hangar door that
was recently delivered for a new 150
ft. x 100 ft. hangar at the John Bell
Williams Airport in Bolton, Mississippi
for John's 360° Coatings aircraft, marine
and vehicle business. Two powerful
hydraulic cylinders lift and secure the
37,472 lb. door in about five minutes.
Schweiss hydraulic doors are
known worldwide for their superior
construction. These doors come
complete with their own self-supporting
header and frame. The durable all steel
frame comes with double or triple push
tubes, faster opening speeds and bigger
and better cylinders.

Spherical Bearings
Because doorframes f lex during
operation, the hydraulic cylinders on
each side of the doorway are connected
to the doorframe and the building
using spherical bearings to increase the
longevity of the door. The spherical
bearings accommodate the f lexibility
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 -
no other manufacturer offers this option.

Beefed Up Hinges with
Grease Zerks
Another plus is Schweiss hydraulic and
bifold doors come with beefed up wraparound hinges with removable hinge
pins and grease zerks on each hinge for
easy lubrication eliminating the need
to remove the top rubber weatherseal.

Compact Powerful Pump
The Schweiss hydraulic power or pump
unit comes from the factory fully
assembled and ready to operate. Each
unit comes pre-wired and factory tested,
complete with a 24 V.A.C. control
system and direct drive motor protected
by an oil filter and complete with gauges.
The power units are also available with
a 12-volt remote operated battery backup system or built-in tractor back-up
fittings in case of a power outage.

Automatic Windpins
