Doosan expands its Tier 4 excavator lineup with the DX140W-5 and DX190W-5 for applications that require an excavator with rubber tires. The 132-net-horsepower DX140W-5 and 168-net-horsepower DX190W-5 wheel excavators stand out with rubber tires for operations which regularly drive on finished concrete or asphalt surfaces such as highway / street development, building, manufacturing operations, site development and land improvement. The SPC engine model features variable speed control and pump torque control. Variable Speed Control reduces engine rpm during low workload requirements such as during the swing portion of a dig cycle. This reduces the total energy required to perform a task and improves fuel efficiency by up to 3 to 7 per cent. Pump Torque Control matches hydraulic pump torque and engine response to the task, preventing engine overload and excess fuel consumption, improving efficiency. Machine updates include: Ergonomic joystick for improves operator comfort and ease of use; relocated rear camera enhances rear visibility; camera monitor allows operators to monitor machine information while camera is on; floor pedal adds optional way for operators to activate two-way auxiliary hydraulics; alternator upgrade provides 80 amps for improved performance; emergency stop relocated making it easier for operators to reach on the seat base. www.doosanequipment.com
