TF-880™
The TF-880™ TecsPak® friction draft gear is the lightest weight high-performance
M-901E draft gear, allowing extra payload capacity and greater car
design flexibility. The TF-880 utilizes a patented TecsPak® elastomer
compression spring package and proven friction clutch design. With
44% more energy absorption than double-coil spring designs, the TF-880
not only provides greater spring capacity, it can significantly reduce
the transfer of damaging force to the railcar.
TF-880 draft gears examined from service applications of more than one million
miles have consistently demonstrated the TF-880's sustained high capacity under
a wide variety of operating conditions.
