In the UK Doosan excavators (and wheel loaders for that matter) and gaining popularity. The takeover of Daewoo by Doosan in 2005 led to some significant quality improvements and the latest DX series of excavators are thought by many to be up to Japanese build standards.
From what I’ve seen and heard, they are good reliable products, but they have probably reached their limit, considering Doosan’s current manufacturing facilities. However, Doosan is in the process of building a brand new factory in Korea, so I would expect even better products in the future.
Regarding AtlasRob’s point on Terex/Atlas German-built TC excavators for European markets, these have not been a great success. No load-sensing hydraulics, coupled with high production costs, has not tempted many buyers away from Japanese and Korean built machinery.
