DOOSAN DX140W CRAWLER EXCAVATOR

Technical Description

The Doosan DX140W is a highly versatile wheeled excavator designed for efficient operation in various construction and site development tasks. Powered by a turbocharged Doosan DL06 engine with an air-to-air intercooler, it delivers 132 hp (98 kW) at 2000 rpm and produces 383.6 lb-ft of torque at 1400 rpm, ensuring robust performance and compliance with stringent Tier 4 emission standards. The excavator operates on a hydrostatic powershift transmission featuring three forward and three reverse gears, allowing a maximum travel speed of 23 mph (37 kph) for excellent mobility on paved and rough surfaces. Its hydraulic system offers a pump flow capacity of 82.5 gallons per minute, with a relief valve pressure set to 4699 psi, enabling smooth and powerful operation of boom, stick, and attachments. The unit’s operating weight measures approximately 30,314 lbs, with a ground clearance of 1.2 ft and a wheelbase of 9.2 ft. Multiple boom and stick configurations provide versatile reach and digging capabilities: option 1 offers a max digging depth of 15.0 ft and max reach along ground of 24.7 ft; option 2 extends digging depth up to 24.6 ft and cutting height up to 27.5 ft; options 3 and 4 further increase cutting heights to 29.1 ft and 29.9 ft, respectively. Loading heights range from 19.1 ft to 22 ft depending on configuration. Additional features include an advanced disc brake system acting on the hubs for improved braking reliability, a 24V electrical system with a 60-amp alternator, 74-gallon fuel capacity, and 41 gallons hydraulic fluid capacity. The excavator rides on robust 10.00-20-14PR tires designed for optimum traction and stability during operation. The cab height stands at 10 ft, with shipping dimensions ranging roughly from 23 to 26 ft in length and 10.6 to 12 ft in height, facilitating transport and job site access. This combination of power, reach, and mobility makes the DX140W ideal for roadwork, utility, and general construction applications.
