The track castors are designed to use over inverted angle iron tracks or over square section or over rails. Cast iron wheels with either V-groove or square groove or a flange are available depending upon the track over which the castors have to move. Since the wheel rolls on steel track, the pushing or puling force required is much less. This reduces labour fatigue. Floor surface also does not get damage at any time. The track wheels can be fitted in fixed & swivel brackets of MD or HD series.
