Wedge Lock Coupler Attachment

Doosan's wedge lock coupler manual mounting system allows operators to change excavator attachments without the need for additional hydraulics but does not decrease a machine's breakout force.

  • Limited increase in tip radius over pin-on mounting
  • Designed to allow for use of multiple attachments
  • Swing ear design and bolt retainer safety plate helps prevent attachments from falling
  • Approved for use on 13 Doosan crawler-excavator models: 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
