ST22E extend track bulldozer 220T
Features
The ST22E extended track bulldozer is a modification of the ST22, featuring advanced performance, high reliability, low fuel consumption and convenient maintenance. The machine has an extended track, increasing the overall length of track on the ground and thereby reducing ground pressure. With excellent maneuverability, the ST22E is well adapted to the earth moving operations on soft ground.
