In the case of frequent replacement of excavator attachments, the operator can use the hydraulic quick hitch to quickly switch between the hydraulic breaker and the bucket. No need for manual insertion of bucket pins. Turning on the switch can be completed in ten seconds, saving time, effort, simplicity, and convenience, which not only improves the excavator working efficiency, but also reduces the wear and tear of the excavator and the attachment caused by the replacement.
The operation steps are as follows:
1、Rise up the excavator’s arm and slowly grab the bucket pin with a fixed tiger mouth of the quick coupler. Switch status closed. (See image 1 & 2).
2、Open the switch when the fixed tiger mouth grabs the pin tightly (Buzzer alarming). The quick coupler cylinder withdraws back and at this time, lower the quick coupler movable tiger mouth to the bottom.
3、Close the switch (the buzzer stopping alarming), the movable tiger mouth stretching out to grab the other bucket pin.
4、When it completely tops the pin, plugs the safety pin. (Figure 5)
