During World of Concrete 2022, Doosan Infracore North America introduced three new pieces of construction equipment designed to help improve productivity and efficiency for customers. The new machines include:
- 14-metric-ton, reduced-tail-swing Doosan DX140LCR-7 crawler excavator
- 48.8-hp Doosan DX50Z-7 mini excavator
- Doosan DL250-7 wheel loader
Both excavators are part of next-generation product introductions the company plans to make for the North American market. The new -7 Series crawler excavators Doosan intends to bring to market will be designed to offer enhancements in power, performance and serviceability to help improve customers' operations. There will also be upgrades to visibility and safety for further productivity gains.
Doosan also intends to introduce a brand new line of mini excavators which will include models not previously available in North America. The company says this will allow it to provide more options for its customers to meet their various application needs. Conventional tail swing, reduced tail swing and Zero Tail Swing configurations will be part of the new mini excavator lineup. Doosan's telematics system DoosanCONNECT will also be available as standard for the first time, the company says.
Following are details on the new excavators and wheel loader as provided by Doosan.
Doosan DX140LCR-7 Crawler Excavator

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.
