Doosan Wedge Lock Coupler

Doosan has released the wedge lock coupler for use with the company’s 6- to 53-metric-ton crawler excavators.

This attachment adds to the Doosan coupler line, which currently includes the hydraulic quick coupler. The wedge lock coupler manual mounting system is approved for use with 13 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.

It allows operators to change their excavator attachments without the need for additional hydraulics, but does not decrease a machine’s breakout force. The coupler has a limited increase in tip radius over pin-on mounting.
