Rated belt tension can exceed 100%, with a maximum of 150%, during starting and stopping conditions. Fastener size recommendation may vary due to cover
thickness, pulley diameters, and system tension.
Consult your GTM or fastener manufacturer. R6 fasteners must be installed with stainless steel rivets when belt tension exceeds 140kN/m for best results.
P/N = Poly / Nylon N/N = Nylon/Nylon
*
Average Permanent elongation values at 100% of rated belt tension are based on ISO 9856 test procedure. Consult your GTM or GAD for elastic & total
elongation calculations. Consult your GTM for vulcanized splice method for Coal Quest constructions.(Do not use any bias or overlap design).
