STANDARDS TESTING LABS PRODUCES 10' DIAMETER TIRE AND WHEEL RADIAL FATIGUE
MASSILLON, OH (September 10, 2004) - Standards Testing Laboratories (STL),
the world's largest independent testing facility for tires, wheels and
related automotive components, recently completed production of a new 10'
diameter tire and wheel radial fatigue testing machine.
is a very impressive piece of equipment and is one of the largest test
machines that we've built. It was quite an achievement and is a perfect
example of the type of custom machinery we're capable of developing for our
OEM and tire and wheel industry customers," said Cheryl Schnuth, vice
president, marketing and technical sales, Standards Testing Laboratories.
"This state-of-the-art equipment was designed with technologies that
facilitate ease of use while increasing accuracy and control of the test
STL's ten-foot tire and wheel radial fatigue test machine, a product of its
Machinery Division, features hydraulic loading with a self-contained
hydraulic power unit and closed loop control. High and heavy loading can be
accomplished via a yoke mount spindle assembly, and two test positions are
available on the multi-piece framed machine.
An Allen-Bradley PLC controller for machine control and a touch screen
operator interface, which displays speed, load, elapsed test time, elapsed
test mileage, and ambient temperature are featured on the unit. And, as an
added convenience, the PLC and computer interface through an Ethernet
connection, allowing for remote operation.
Capable of measuring lateral force, the tire and wheel radial fatigue test
machine's road wheel measures 120 inches in diameter, with a variable
testing width of 36 to 48 inches. Traceable calibration standards are
available for load, speed, and air pressure.
For testing, the machine speed is variable from 2- to 50-mph with load
parameters up to 100,000 lbs. Spindle braking is possible for enhanced
safety. Speed and load is accurate plus or minus one percent of operator set
points for precise control and calibration. Air pressure can be controlled
from 10- to 150-psi with a remote inflate/deflate for improved operator
safety. The machine requires 460V, 60HZ 3 phase or 380V, 50HZ 3 phase power
The Machinery Division of Standard Testing Labs (STL), Inc. has been serving
the tire, wheel and automotive industries with custom testing equipment and
testing assistance for more than 30 years, handling the design and
production of machinery, instrumentation and computerized controls for
automotive test equipment. The division also modifies, reconditions, and
performs field service and calibration for machines in the field.
Standards Testing Laboratories (STL) operates as the world's largest
independent testing facility for tires, wheels and related automotive
components. Through its four divisions, STL provides the rubber and
automotive industries with dynamic laboratory testing, static and physical
testing, fleet testing, test machines, specialized photographic and video
services and consulting services.
