The Cat® MH3050 offers superior performance within its size class. A wide undercarriage and stabilizer footprint keep the machine sturdily in place, while the boom and stick options combine to provide up to 18 m (59’1”) reach. The MH3050 combines components from next generation Cat excavators with the material handler cab to bring you maximized productivity, enhanced comfort, and the reliability you expect from your machine.
