Doosan DL550-5



With the highest horsepower, tipping capacity and breakout force in the Doosan® wheel loader lineup, the DL550-5 is a heavy-duty performer that is agile and smooth despite its size.

Designed for the largest material handling applications, the DL550-5 is ideal for work in quarries, mines, demolition and industrial operations.

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.

Through reduced cycle times and increased uptime, you'll improve your bottom line. It's powered by a diesel engine that delivers power or economy modes to match your job requirements. Operate in manual, automatic or semi-automatic transmission modes.

Other performance features on the DL550-5 include a powershift transmission with, optimized hydraulic pumps, Z-bar lift arm, return to dig, limited slip rear differential, and hydraulic locking front differential.

An efficient cooling system features an all-aluminum reversible fan, rubber mounts that reduce vibration, and optional an 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.

Multiple cab improvements 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 increase controllability. Additional features include heated mirrors with better positioning, a sun visor, and an optional rearview camera.

To reach Tier 4 emissions standards, the DL550-5 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).
