Doosan’s new wedge lock coupler allows for fast attachment changes with no decrease in excavator breakout force

Change excavator attachments without decreasing breakout force with Doosan’s wedge lock coupler designed for use with the company’s 6- to 53-metric-ton excavators.

The wedge lock coupler allows for the use of multiple attachments, such as heavy-duty digging buckets, trenching buckets and high-capacity bucket models. The coupler also pairs with Doosan’s excavator clamp attachments.

To boost jobsite safety, the wedge lock coupler features a swing ear design and a bolt retainer safety plate that helps keep the attachments from falling. The coupler has a limited increase in tip radius over pin-on mounting.

The wedge lock coupler manual mounting system fits 13 crawler-excavator models:

• DX63-3
• DX85R-3
• DX10LC-3
• DX140LCR-3
• DX180LC-3
