The Cat 352 hydraulic excavator is built to take on your up-close and far-out excavating tasks. The 52-tonne machine features a variable gauge undercarriage that retracts for transport and expands to help increase stability and lift capability. Particularly helpful when you do a lot of work over the side. Where the real power comes in is through the integrated engine, hydraulic, and work tool systems. You can move tonnes of material – literally – every hour, on the hour, all day long with a great deal of speed, precision, and efficiency.
