Fits Your Needs For Every Job.
Complete more tasks with the Doosan® DX140W-5 wheel excavator. Its fast travel speeds allow you to easily travel to nearby job sites. Complete utility repairs, construction tasks, street maintenance as well as many other tasks.

Its modular frame design allows you to easily configure the machine’s undercarriage with a dozer blade or outriggers. Level or backfill material with the dozer blade, or stabilize the machine during digging applications. Control the outriggers individually to level the machine on slopes.

Optimum Ground Clearance.
The front axle oscillates and provides an excellent steering angle for maneuverability but can be locked for better digging and lifting performance. The rear axle is fixed. The transmission is mounted directly to the rear axle for protection from obstacles and optimum ground clearance.

Get More Fuel Savings.
The Electronic Power Optimizing System (EPOS) deliver optimum power and fuel efficiency. The design optimizes combustion and torque for faster cycles and maximum results. Four work modes, auto-idle and machine diagnostics help you manage your fuel costs. Smart Power Control (SPC), when enabled, improves machine efficiency while maintaining productivity and reducing fuel consumption when you operate in Work Mode.

Maximum Comfort.
A spacious cab means better visibility and more productivity. High-performance air conditioning, extra storage and an optional air suspension seat give you better comfort, while ergonomically-designed joysticks provide maximum operating comfort. Use the floor foot pedal to control two-way auxiliary functions. During long work days, you'll appreciate the reclining, height- and weight-adjustable standard suspension seat with a headrest and adjustable armrest. An emergency engine shut off is conveniently placed at the seat base.

Easy Maintenance.
Enjoy reduced maintenance costs and extended machine life with the durable chassis, strengthened boom and arm assembly, and extended greasing intervals. Easily access the oil filter, air cleaner, fuel filter, radiators and other engine components. The centralized boom and arm grease points are grouped for easy maintenance.
