QUICK COUPLER CIRCUIT AND QUICK COUPLER ATTACHMENT/DETACHMENT METHOD

SATO KOJI / TAKIGUCHI TAKAHIDE

In this quick coupler (20), a boosting valve (25) switches to a boosting position (Q1) and a coupler changeover valve (27) switches to a lock-side position (R1) when a changeover switch (28) switches to a lock position (S1). When the changeover switch (28) switches to a hold position (S2), the boosting valve (25) switches to a non-boosting position (Q2) and the coupler changeover valve (27) switches to the lock-side position (R1). When the changeover switch (28) switches to an unlock position (S3), the boosting valve (25) switches to the boosting position (Q1) and the coupler changeover valve (27) switches to an unlock-side position (R2).
