Types of Loader Testing
Torque Driver Testing
An accessory torque screwdriver testing kit, 2000-750-02, is
available for use in testing or calibrating most torque
screwdrivers and "T" handled drivers. In addition to providing
perfect driver-transducer alignment, it allows the use of the
2000-800-02 loader crank for precision torque application.
Certain torque screwdrivers, "T" handled drivers, electric or
pneumatic nut runners, and non-impact power tools must be
tested by hand. Double check to be sure that the transducer
you choose is capable of handling the maximum torque that you
will apply. Hold the tool exactly in line with the transducer drive
while testing. Off-axis side loading may compromise the test or
calibration of the tool.
Torque Multiplier Testing
The 2000-800-02 Motorized Loader and MULTITEST series
transducers can be configured to test certain torque multipliers.
The 2000-810-01 Indicator also provides measurement, display,
storage and statistical analysis of multiplier output torque to
2,000 ft lbs.
In practice, the multiplier is attached to the loader using custom
fixturing. The operator provides input torque with an
appropriate wrench, breaker bar or the multiplier’s integral hand
crank.
Various mounting fixtures, adaptors, reaction stops and pins are
available for testing the most common torque multipliers. Ask
your CDI sales representative for design assistance.
