Develon (formerly Doosan) continues to position the DL380-7 as the anchor of its -7 Series large wheel loader lineup - a 44,919-pound operating-weight machine powered by a Doosan DL08 diesel engine delivering 271 hp (202 kW) at 1,800 rpm, paired with a 4.8 cu yd standard bucket (7 percent larger capacity than the DL350-5 it replaces) and a powershift 4-speed transmission. The DL380-7 is designed for aggregate production, general construction, and industrial yard work where bucket capacity, cycle speed, and machine availability determine fleet profitability - and where the machine must sustain high productivity across continuous load-and-carry duty cycles.
The machine's defining engineering feature is the "Standard Transparent Bucket option" - Develon's exclusive camera-based visibility technology that provides a supplemental visual perspective, allowing operators to "see-through" the bucket from an in-cab display. Combined with the "Develon Smart Guidance System" (DSGS) - a customized analytical tool that monitors operator driving habits and provides personalized feedback to optimize machine operation and fuel economy - the DL380-7 gives operators and fleet managers visibility into productivity that competitive machines achieve only through external telematics add-ons. The machine's "Smart Touch" screen allows operators to monitor critical machine functions, control machine settings including heating and cooling, and access the DSGS and Transparent Bucket features through a single integrated display.
The DL380-7's structural architecture reflects the higher bucket capacity it delivers: "stronger and larger axles" and a "strengthened box frame" support the heavier material loads moved with each pass, and the larger axles also provide better braking capacity to extend the lifetime of the brake discs. The machine's parallel lift system with electro-hydraulic compensation maintains bucket orientation throughout the lift cycle - reducing material spillage during truck loading. Combined with enhanced steering system response, a Z-bar lift arm delivering strong breakout force, wider radiator fin spacing for improved cooling efficiency in dusty environments, an enhanced cab visibility with 20 percent more glass area, and a rearview camera, the DL380-7 positions itself as a direct competitor to the Caterpillar 950M, Komatsu WA380-8, Volvo L110, CASE 821G, and LiuGong 856H Max in the global large wheel loader segment.
