Doosan (now Develon) positions the DX140LCR-5 as the anchor of its mid-range reduced-tail-swing crawler excavator lineup - a roughly 14-ton machine engineered to deliver conventional-tailswing productivity in a package that can work safely alongside traffic, against walls, and in restricted-access sites where a full-tail-swing excavator cannot operate. Powered by a Cummins diesel engine delivering 113 hp net output, the DX140LCR-5 pairs its compact footprint with a bucket breakout force of 24,471 lbf and arm digging force of 13,288 lbf - class-leading figures for the 14-ton reduced-tail-swing segment.
The machine's defining engineering feature is the "reduced-tail-swing" architecture: the DX140LCR-5's tail swing radius is 45 percent shorter than a conventional-tailswing excavator of the same class, while the front swing radius is 24 percent smaller - allowing the upper structure to slew within its own track footprint without rear-end overhang. This means the excavator can work immediately adjacent to traffic barriers, excavations, walls, and existing structures without rear-end collision risk. Combined with a maximum digging depth of 19 feet 7 inches and a maximum ground-level reach of 27 feet 11 inches, the DX140LCR-5 delivers the dig envelope of a full-size 14-ton machine in a chassis that can work in tight quarters.
The machine's electronic control system offers four power modes - Power+, Power, Standard, and Economy - allowing the operator to prioritize maximum dig force for rock work or minimum fuel consumption for precision grading. Four work modes - Dig, Lift, Breaker, and Shear - tailor the hydraulic system's response to the specific attachment in use, with breaker and shear modes providing flow-limited control for hydraulic attachments. The redesigned cab features improved visibility, an upgraded air-suspension seat, and Doosan's Smart Key keyless-start system for fleet-shared machines. Combined with a redesigned RTS (reduced-tail-swing) counterweight that maximizes stability without increasing overhang, the DX140LCR-5 positions itself as a direct competitor to the Kubota KX080, Yanmar Vio80, and Volvo ECR145 in the global 14-ton compact excavator segment.
