The new coupler gives excavators flexibility to carry out different work on the job site.
The power tilting coupler is approved for the following Doosan excavators: the DX63-3 compact model; DX140LC-5 through DX255LC-5 crawler models; and DX140W-5 through DX210W-5 wheeled models. This new option gives increased excavator flexibility, versatility and precision when digging trenches, general excavation applications and final grading tasks. Doosan excavator operators can now angle a trenching or ditching bucket 67 degrees left and right for up to 134 degrees of flexibility. Excavator operators can save time when using the coupler because they will not have to reposition the excavator as frequently while working, or stop to change attachments to perform certain tasks.
The Doosan power tilting coupler provides precision while digging and can work under or around objects, such as an underground pipes, to complete excavating tasks. It can also eliminate the need for multiple attachments on a jobsite. This can be most beneficial for operators working in general excavation, underground utility, landscaping and grading, and erosion control applications. In demolition applications, the ability to tilt a breaker attachment can help excavator operators reach concrete without repositioning the machine.
