Impact Resistance
Goodyear Engineered Products underground belts come well prepared to withstand the
worst. That’s because loading impact damage, a major cause of belt failure, is already
assessed and predicted at our Technical Center laboratory. During the design phase, our
design engineers utilize an enhanced Dynamic Impact Tester to accurately simulate
loading impact force and its effects on belting. It is information like this that contributed
to the design of our Triple-Warp™ fabric weave.
Flame Resistance
Underground coal belts require additional flame resistance and flame propagation cover
properties. Our SHIELD
™
compound exceeds MSHA’s part 14, B.E.L.T. flame resistance
and flame propagation requirements while also providing low smoke toxicity and density
safety characteristics as well as outstanding abrasion resistance. We also offer standard
ARMA compound for ASTM D378 Part 13.2 flame resistance and ARMA II
where superior abrasion resistance is required. See the compounds section on page
82
for available compounds.
Tear Resistance
A misaligned belt can suffer edge tears by running into the structure. Tears can also occur as
a result of material punctures. Thanks to the extremely high transverse tear strength of
Coal Quest belts, these occurrences are minimized and contained.
Rip Resistance
Scrap metal and other debris can penetrate and greatly damage a belt. If these foreign objects
get hung up in the structure, it can lead to equipment damage, material spillage and even
slits or cuts in long sections of the belt. The Triple-Warp fabric design of Coal Quest belting
helps dislodge and expel foreign objects and contain rips to a small area.
Fastener Retention
The mechanical fastener splices of Coal Quest belts are rated at 100% of the rated working
tension. At our world-class Technical Center, these splices have undergone rigorous dynamic
and static testing, which enables the belt to offer superior mechanical fastener retention vs.
multi-ply and straight-warp constructions.
Vulcanized Finger Splice
A finger over finger vulcanized splice is recommended for Goodyear Engineered Products
Coal Quest belting. This splice method takes advantage of the supior strength properties of
the Coal Quest carcass to offer 100% of the rated belt tension.
