A COUPLER FOR THE WORKING ARM(S) OF AN EXCAVATOR OR THE LIKE

摘要

A system for coupling an attachment to a power-driven arm of a machine such as an excavator including: a coupler for fitting to said arm and an interengaging mechanism arranged so as to couple the attachment to the coupler. The at least one interengaging mechanism automatically interengages utilising a catch which has a resiliently biased action as the coupler is moved into the mated position with the attachment by the arm. The coupler push-fits to the attachment.
