The hydraulic quick hitch joint requires modification of the excavator pipeline and hydraulic system to meet the needs of automatic replacement of the working device (convenient, practical, and cost-effective), and is used to frequently switch various accessories of the excavator (digging bucket, scarifier, crushing hammer, and grabber). Hydraulic quick change can be easily replaced with various accessories, which is quite convenient and fast for excavator operators. Compared to mechanical quick change, hydraulic quick change is safer, and there is no need to twist the lead screw when getting off the car. Slowly, mechanical quick hitch is completely replaced.
Hydraulic quick hitch replacement principle
1. Use a safety device with a hydraulic control one-way valve to ensure safety.
2. The excavator configuration components can be replaced without modification or disassembly of the pin shaft, so installation is fast and can greatly improve work efficiency.
3. There is no need to manually smash the bucket pin between the crushing hammer and the excavation bucket. Gently moving the switch for ten seconds can complete the exchange between the excavation bucket and the crushing hammer, which is time-saving, labor-saving, and simple and convenient.
4. Mainly used in workplaces that require frequent replacement of the front-end working device of excavators, it is recommended to avoid installing a device for long-term use.
