Doosan DL250-7 Wheel Loader

The Doosan DL250-7 wheel loader has smart technologies to amplify operators' ability to scoop, carry and load more material — while maximizing power and efficiency. Exceptional lift heights and generous bucket capacities help operators power through the heaviest loads. The standard Z-bar lift arm delivers excellent breakout force for digging in tough materials. 

There’s also a high-lift option for maximum dumping height. Both are ideal for heavy lifting in loading applications, with rapid bucket movement and proper angle positioning for precision performance. Customers can add a larger, optional counterweight for even more lifting flexibility. The standard Z-bar lift arm on the DL250-7 delivers excellent breakout force for digging in tough materials.The standard Z-bar lift arm on the DL250-7 delivers excellent breakout force for digging in tough materials.Doosan Infracore North America
