Caterpillar 320
A tracked hydraulic excavator: a vehicle designed not to carry but to dig and load.
Overview
The 320 designates a mid-class tracked hydraulic excavator. Construction machines sit at an unusual end of the vehicle category: travelling is not a purpose but a way of reaching the position where work can be done.
Tracked undercarriage spreads weight over a wide surface and makes work on soft ground possible. A wheeled machine relocates faster but sinks on the same ground; the choice follows the character of the site.
Hydraulics are the real subject of these machines. Boom, arm and bucket movements are produced by pressurised fluid, and the system's response time shapes the quality of the work as much as the operator's precision does.
