Develon (formerly Doosan) continues to position the DX235LCR-7 as the anchor of its -7 Series reduced-tail-swing crawler excavator lineup - a 57,133-pound (25,915 kg) operating-weight machine powered by a Develon DL06V Stage V diesel engine delivering approximately 170 hp (127 kW) of output, paired with a maximum swing torque of 69,625 lbf·ft and a maximum swing speed of 11.5 rpm at efficiency. The DX235LCR-7 is designed for congested job sites such as roadways and rail lines - environments where a conventional-tail-swing excavator would block adjacent traffic lanes or track, and where the machine must work productively within the confined swing-clearance envelope that urban infrastructure and rail-corridor maintenance requires.
The machine's defining engineering feature is the "reduced tail swing counterweight design" - a compact upper-structure architecture that delivers a tail swing radius of just 5 feet 8 inches (1,724 mm), with the tail swing overhanging the track's side edge by only 5 inches (129 mm) on standard 24-inch track shoes. This near-zero tail-swing architecture allows the DX235LCR-7 to work close to buildings, walls, and roadside obstacles without the risk of upper-structure contact damage that conventional-tail-swing machines would face in the same working envelope - while the long carriage design maintains exceptional stability across all operating conditions, including heavy digging and lifting.
The DX235LCR-7's working performance includes a bucket capacity of 1.2 yd³ (0.92 m³) SAE-heaped, bucket breakout force of 33,510 lbs, and arm breakout force of 23,810 lbs - with the machine's power boost function increasing both forces by approximately 5 percent when maximum digging force is required. Combined with a maximum travel speed of 3.6 mph, a maximum gradeability of 70 percent (35 degrees), a hydraulic system capacity of 50.2 gallons, and Develon's established global dealer and parts network, the DX235LCR-7 positions itself as a direct competitor to the Komatsu PC228USLC, Caterpillar 326, Volvo ECR235E, and Hitachi ZX225US in the global reduced-tail-swing 26-ton excavator segment.
