Doosan DL420-5

 

With impressive digging and high tractive power, the Doosan® DL420-5 wheel loader excels in tough applications. It's designed to take on a wide range of material handling tasks from loading and transporting granular material (such as sand and gravel) to industrial, mining and quarrying applications.

Powered by a powerful Tier 4 diesel engine, you'll penetrate tough materials, tilt and lift with ease, and carry more in every cycle. Performance features include a powershift transmission with optimized hydraulic pumps, multiple power modes, Z-bar lift arm, return to dig, and limited slip differentials on both front and rear axles.

With the high lift option, you’ll gain additional lift height and reach. Easily load materials like cement, coal, grain, fertilizer, or waste into high-sided trucks, hoppers or mixers. High lift is ideal for processing plants, scrap and recycling facilities, and agricultural operations.

An efficient cooling system features an all-aluminum reversible fan, rubber mounts that reduce vibration, and an optional axle cooler that prevents the oil temperature from rising to dangerously high levels. Monitor your Doosan equipment and manage maintenance to reduce operating costs with Doosan Connect Telematics.

There's also better visibility thanks to lowered front side glass panels. Heated mirrors with improved positioning help you stay aware of what's behind you, while a sun visor helps you see your work. For an additional view of your machine's surroundings, the rearview camera comes standard.

To reach Tier 4 emissions standards, the DL420-5 incorporates a high-pressure common-rail (HPCR) fuel delivery system as well as cooled exhaust gas recirculation (CEGR) combined with a diesel oxidation catalyst (DOC) and selective catalyst reduction (SCR).
