Doosan Wedge Lock Coupler Attachment
If your rental fleet includes a Doosan crawler-excavator, the new wedge lock coupler attachment can benefit you and the customers renting from you. The wedge lock coupler allows operators to change their excavator attachments without the need for additional hydraulics, but does not decrease a machine’s breakout force.
Doosan has released the wedge lock coupler for use with 13 of its crawler-excavator models including the DX63-3, DX85R-3, DX140LC-3, DX140LCR-3, DX180LC-3, DX225LC-3, DX235LCR, DX255LC-3, DX300LC-3, DX350LC-3, DX420LC-3, DX490LC-3 and DX530LC-3.
The wedge lock coupler is designed to allow use of multiple attachments, such as Doosan’s line of heavy-duty digging buckets. It also mounts the company’s current offering of trenching buckets and is capable of efficiently releasing high-capacity bucket models. The new coupler will also pair with Doosan’s excavator clamp attachments. The new coupler has a limited increase in tip radius over pin-on mounting. In an effort to increase jobsite safety, the wedge lock coupler’s swing ear design and the use of a bolt retainer safety plate helps prevent attachments from falling.
