Key Specifications

Smart Technologies Work smarter and more efficiently thanks to a long list of machine technologies included on the DX140LCR-7. The Electronic Power Optimizing System (EPOS) and the exclusive Smart Power Control (SPC) optimize machine performance while improving efficiency. The optional 360-degree all-around view monitoring (AVM) provides five unique visual perspectives around the cab from the monitor — for improved jobsite awareness. An auto shutdown feature saves fuel and helps lower warranty hours. And the standard DoosanCONNECT® Telematics system monitors the excavator’s health, location and productivity.
