Quick-disconnect coupling for a machine having a boom and a stick |
| abstract |
A heavy-duty machine, such as an excavator, having a boom mounted for motion in a generally vertical arc, a stick mounted onto the distal end of the boom, and a tool mounted at the distal end of the stick. The stick is connected to the boom by a quick-disconnect coupling including a coupling member that is rockably mounted at the distal end of the boom and a coupling member mounted at the proximal end of the stick. A grab hook on the boom coupling member is used to pick up the stick by hooking onto a grab pin of the stick coupling member. A set of rack gear teeth on the boom coupling member intermesh with a corresponding set of rack gear teeth on the stick coupling member, and these eliminate play between the stick and boom. A quick-disconnect hydraulic coupling including a female coupling element mounted on the boom coupling member with a remotely operable locking means, and a male coupling element mounted on stick coupling member provide automatic coupling of hydraulic lines between the boom and stick when the coupling members are brought together. |
