Doosan hydraulic thumbs for crawler and wheel excavators allow operators to quickly and easily pick and place material in demolition applications. The thumb edges keep objects secure for precise loading and material handling. A heavy-duty cylinder is designed for the demanding applications. Thumbs can quickly be installed on the excavator dipper to maintain productivity, while a load-holding valve helps prevent spillage. Doosan hydraulic thumbs are approved for use with DX140LC-5 through DX300LC-5 crawler excavators, and DX140W-5 through DX210W-5 wheel excavators.
