An excavator quick hitch, also known as a quick coupler or quick attach, is a device used to quickly and easily change attachments on an excavator. It is essentially a mechanism that allows the operator to quickly disconnect one attachment and connect another without having to leave the cab of the excavator or use tools.
Excavator quick hitches typically consist of two parts: a coupler that attaches to the excavator arm, and a set of pins or lugs that attach to the attachment. The coupler and pins are designed to fit together securely, allowing the attachment to be quickly and safely connected to the excavator.
1. Compatibility: Quick couplers are designed to be compatible with a wide range of excavator sizes and attachment types. This allows for greater flexibility and versatility on job sites.
2. Ease of use: Quick couplers are designed to be easy to use and require minimal training or expertise to operate. This can help save time and reduce the risk of operator error or injury.
3. Maintenance requirements: Quick couplers typically require minimal maintenance and are designed to be easy to clean and inspect. Regular inspections and maintenance can help ensure safe and reliable operation over the long term.
