MAXI-DUTY
CASTERS
(Series
MD)
Move
up to
10 tons
on Maxi-Duty
Casters,
designed
and built
for the
toughest
applications
including
shipbuilding,
manufactured
housing,
automotive
and aerospace.
Long life
and dependable
service
are assured
with Hamilton's
premium
forged
steel
swivel
construction.
All forged
steel
wheels
are machined
with a
slight
crown
to enhance
rollability
and swiveling. |

MAXI-DUTY
DUAL WHEEL
CASTERS
(Series
MDD)
This
dual-wheel
series
version
of the
Maxi-Duty
caster
addresses
the problem
of how
to restrict
overall
height
while
at the
same time
provide
adequate
carrying
capacity
on resilient
tread
wheels.
Dual-Wheel
Casters
also improve
stability
and swivel
more easily
than wider-face
single
wheels
because
differential
action
reduces
the “scrubbing”
effect
of soft
treads
against
the floors. |
| Swivel
Construction |
5/8"

CUSH-N-AIRE
CASTERS
(Series
7000)
Hamilton
Cush-N-Aires
have become
widely
recognized
as the
leading
pneumatic-
tired
casters
in the
industry.
The quality
that earned
this reputation
continues
without
compromise:
all swivels
are S.A.E.
1045 drop
forged
steel
with an
integrally
forged
kingpin
and precision
tapered
thrust
bearing
to ensure
easy swiveling
and longer
life.
These
shock
absorbing
casters
are popular
for handling
missile
components,
electronic
equipment,
ceramics,
liquids,
etc.,
as well
as for
use outdoors
over rough
surfaces.
Pneumatic
tires
offer
“variable
flotation”:
reduce
inflation
pressure
to improve
cushioning
for lighter
loads,
or inflate
fully
for optimum
rollability
and capacity
loads.
All wheels
except
the 4-ply
16"
size have
bolted
hubs.

V-GROOVED
WHEEL
CASTER
(Series
V)
Grooved
Casters
are finding
increasing
applications
on industrial
carts,
assembly
fixtures,
containers,
racks
and other
equipment
where
it is
desirable
to control
direction,
protect
floors
and provide
ease of
movement.
Typical
track
plans
are linear
although
curves,
switches
and turntables
may be
added
to provide
a multi-directional
control
system
(in which
case swivel
casters
must be
used).

Hamilton
Flanged
Wheel
Casters,
like their
V-Grooved
counterparts,
are also
finding
increasing
industrial
applications
where
floor
protection,

it is
often
more convenient
to purchase
flanged
wheels
in a plate-type

More
information and history
about Hamilton:
There's no substitute
for experience–
ours, or yours. Thus
reads a Hamilton advertising
slogan expressing
how experience benefits
the user. Today's
customers benefit
in very real ways
from the
improvements in designs,
materials and manufacturing
methods developed
during Hamilton’s
90+ years in business.
Founder John A. Weigel
started Hamilton Caster
as a moonlighting
venture from his garage
in 1907, the same
year Oklahoma joined
the Union as the 46th
state and Theodore
Roosevelt was serving
as President. The
company struggled,
but earned a solid
reputation as its
“shoe rack casters”
proved popular in
the marketplace. In
1928 Hamilton entered
the floor truck market
when it acquired H.
Zering Mfg. Co., in
Cincinnati. But by
the late 1930’s
the company was reeling
from the Great Depression
and Mr. Weigel’s
health was failing.
Saving the enterprise
which the founder
had risked so much
to establish required
another great risk
during troubled economic
times. That's when
son-in-law Ralph Lippert
stepped in and purchased
the company in 1939.
His wife, Esther,
served as president
until 1943, when Ralph
became the company's
third president, a
position he held until
1976.
