The excavator’s Track Shoes Steel needs to be replaced when bolt heads are at the same height as track shoe grousers. The bolt heads are never designed to bear the machine. The bolts wear along with shoes until track shoes break & crack due to the overloading. For bulldozers, the rule of thumb is – bolt head height times three. The track shoe grousers should grip into the soil to move the machine. The lower the grousers are the smaller the load that can be moved. Moreover, loose track shoes, often with worn-out holes and are ready for replacement. The combination of steel quality & the hardening procedure is guaranteed for high wear resistance. To safeguard quality & to be sure of required tolerances, so, some manufacturers conduct standard batch inspections in factories. Single grouser track shoes for the bulldozers. • Double grouser track shoes for the heavier machinery & loaders. • Triple grouser track shoes for the excavators. •...
