Doosan DL450-5



Powered by impressive horsepower and breakout force, you can count on the Doosan® DL450-5 wheel loader to handle even the biggest amounts of material. It’s an ideal machine for mining and infrastructure applications.

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.

This wheel loader size is particularly useful for handling granular materials such as sand and gravel in industrial, mining and quarrying applications. The powerful hydraulic system shortens cycle times and the limited slip differentials help you work with confidence in soft or muddy conditions.

The standard Z-bar lift arm design minimizes spillage while increasing productivity. Designed for heavy loads, the lifting geometry has fewer moving parts and precise positioning in all situations. Unload sticky or wet materials with the rapid bucket dump capabilities. Ensure gradual, precise control with the load sensitive control system.

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 heavy equipment and manage maintenance to reduce operating costs with Doosan Connect Telematics.

Multiple cab improvements to make your work easier and more comfortable. With best in-class visibility, you'll see your work better. You'll remain comfortable with automatic air conditioning, an improved steering column, and ergonomically placed FnR joystick controls. The air suspension seat features a right-hand control stand that’s integrated into the seat assembly for increased controllability. Additional features include heated mirrors with better positioning, a sun visor, and an optional rearview camera.

To reach Tier 4 emissions standards, the DL450-5 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).
