Peen Resistant Track Treads

All patented TARCA track load-bearing rails are made from high carbon alloy steel and the treads on both sides of the rail are raised.  The high carbon alloy steel raised treads thus can peen in both directions, and the wheel contact remains flat and straight as it wears.  Thus a "line" contact between the rail tread and the wheel is maintained throughout the life of the track.

Benefits:

• Much longer track life
• Absolute minimum of rolling resistance
• Ensures longer life of carriers and end trucks

Limitations of Competitive Track:

The load bearing rail of other patented track is made of high carbon alloy steel, but with virtually no raised tread.  As a result, the metal can only peen outward from the continual rolling action and the treads eventually start to incline.  The "line" contact between the wheel and tread is lost, the tread surface becomes rough and irregular, and wheel travel becomes extremely difficult.

I-beam track is made of low carbon structural steel.  It has no raised tread.  Because of the mill tolerances of I-beams, the rolling surface on the lower flange varies up and down along the length of the track which accelerates the flange peening.  The "tread" becomes more and  more inclined, rough and irregular.  I-beam track life is much less than patented TARCA track and wheels and bearing wear out faster, too.
