Dynamometer Installation Instructions
General information and warnings
1.3 Safe operation
Keep all the following in mind as you use the dynamometer.
The system capacity is equal to the rating of the dynamometers. The shackle rating
should not be used to determine lift capacity of the system.
The shackles are rated in metric tonnes. Thus the 12-tonne shackles are rated to
26,450 lbf and are suitable for use on the 25,000 lbf dynamometer.
Any zeroed deadload must be considered as part of the ultimate load.
Although this instrument has a substantial overload protection rating, the instrument
should not be used above the rated capacity. Doing so can significantly impact fatigue
life of the instrument and cause premature and abrupt failure. If a higher capacity
reading is needed, Dillon insists that a larger instrument be used.
Safety is always a concern in overhead lifting and tensioning applications. To limit your
liability always insist upon factory supplied shackles and pins and factory tested and
certified safe optional equipment. All DILLON products are designed to meet the
published Safe Working Load (SWL) and Ultimate Safety Factor (USF) standards of the
United States Military. All CE marked models meet the SWL and ULL (Ultimate Load
Limit) requirements of the European Machinery Directive.
Do not grind, stamp, drill or deform the metal on the dynamometer body in any way.
Protect the instrument from impact in use and storage.
Any significant damage or deformation to the loading element is cause for evaluation
by Dillon.
Relieve all torsional and off axis loads.
Apply load in the center of the shackle bow with this instrument.
Off center loading results in substandard performance.
Instrument requires time to stabilize when changing temperatures.
Use only the hardware supplied with this instrument. If no hardware was supplied,
insure that the mating pin and shackle bow is equivalent to the hardware used at
calibration. Otherwise substandard performance or failure can result.
Dillon recommends only using qualified rigging hardware and cannot be responsible for
unapproved hardware.
This instrument is not designed for the following:
l
Applications that see rapid, dramatic temperature swings or thermal shock.
Wide variation in readings can occur.
l
Intrinsically safe environments. This unit has not been Factory Mutual or
ATEX tested.
WARNING: If you overload this dynamometer you could suffer severe injuries
or death. The total load on the dynamometer should NEVER exceed the rated
capacity.
