TRACKED IMPACT CRUSHER
4244i-t
Production and efficiency are the hallmarks of the 4244i-t tracked impact crushers. A progressive material flow path from feeder to output material stockpile minimizes problematic material buildup and results in less maintenance and downtime. The heavy duty build allows the crushers to stand up to the toughest conditions and materials while maximizing fuel economy through direct drive.
