dismantle, rigid enough so that it
could be built to any height and could
be transported and stored without
much effort. After many of his friends
came to his jobsites and saw the mer-
its of this new scaffold, they urged
him to build more (see photo 4).
He applied to the U.S. Patent Of-
fice and on June 16, 1934, his concept
of metal tubular scaffolding received
Patent No. 2,043,498. The scaffold
was revolutionary in concept and he
formed Uecker Equipment Com-
pany. Today metal tubular frame
scaffolding is one of the more com-
mon types used. OSHA standards re-
fer to this as "fabricated frame scaf-
fold." Uecker Equipment Co. went
through many business changes and
today it is known as Safeway Steel
Products, Inc.
TUBE & CLAMP SCAFFOLDING
Tube and clamp scaffolding is not
popular throughout the United
States, for it is more time consuming
to erect and dismantle. It is, however,
used extensively in Europe and in
many east coast cities. It is a very flex-
ible system and is used in tight areas
where other systems could not be
used. Steel tubing is fastened to-

SYSTEMS/MODULAR
SCAFFOLDING
Systems scaffolding is a modular
scaffold that is restricted by the posi-
tion of the ring on each leg. It is a very
flexible system - one that can be built
in many configurations and shapes. It
erects fast and is a very stable scaffold
with a high load rating. It could be
considered an intermediate system
between tube and clamp scaffolding
and frame scaffolding.
SUSPENDED SCAFFOLDING
With the advent of structural steel
and reinforced concrete for the frame-
work of buildings, suspended scaf-
folding became the most economical
method of scaffolding for masonry.
The work platform is suspended
from the roof or floor framing by ca-
ble with a cable drum mechanism to
adjust the platform level. The cables
are suspended from outrigger beams
anchored to the roof or floor. The
hoisting mechanism allows the ma-
son to work waist high, the most effi-
cient level for a bricklayer to work.
The mason swinging stage has a
larger platform that is at least 30
inches wide.
TOWER-TYPE ADJUSTABLE
SCAFFOLDING
In Yankton, South Dakota, mason
contractor Gus Morgen recognized
the benefits of keeping bricklayers at
their most productive level with ma-
terial stocked conveniently. Gus, a
journeyman bricklayer who had
worked on swinging stages, began to
experiment with various designs to
get a product that would embody the
benefits of a swinging stage for load-
bearing masonry buildings. To get an
acceptable support for his adjustable
scaffolding idea, he used 4 by 4 posts
and a block and tackle to raise the
platform. What made it all happen
was the introduction of new welding
equipment, and techniques that
made it possible to build a strong.
welded steel truss tower. A tower that
was strong enough to support the
heavy loads of masonry materials,
but light enough to be erected and
moved on the job by laborers.
With this new concept he designed
