Product Description
operating principle
Hydraulic quick connectors realize the rapid connection and disconnection of hydraulic pipelines through the internal valve core and sealing structure. When it is necessary to connect, align and insert the two connectors. The valve core opens under pressure, and hydraulic oil can pass smoothly. When it is necessary to disconnect, pull out the connector. The valve core closes under the action of a spring to prevent hydraulic oil leakage.

Company Profile
Our Advantages
1.High efficiency and convenience:
1)Quick replacement of work attachments: It can complete the switching of different work attachments such as buckets, breaking hammers, rippers, and hydraulic shears in a short time. Compared with traditional replacement methods, it saves a lot of time. For example, it used to take half an hour or even longer to replace a work attachment. With a quick coupler, it can be completed in a few minutes or even tens of seconds, greatly improving the efficiency of equipment use and increasing the working time of excavators.
2)Simple and convenient operation: The operator only needs to simply operate the control switch or handle to realize the quick connection and disconnection of work attachments, without the need for complex disassembly and assembly operations, reducing the labor intensity of operators.
2.Strong applicability:
1)Suitable for multiple models and work attachments: Quick couplers usually adopt universal design standards and can be adapted to excavators of various tonnages. Whether it is a small, medium or large excavator, it can be used. And it can be connected with various types of work attachments, such as buckets of different specifications, breaking hammers, and log grapples, expanding the use range and functions of excavators.
2)Adapt to various working conditions: In various working scenarios such as construction, road construction, and mine mining, the quick coupler can exert its advantage of quickly replacing work attachments, so that the excavator can quickly switch to the appropriate working mode according to the actual working conditions.
3.Safe and reliable:
1)Safety device guarantee: Generally equipped with safety devices such as hydraulic check valves and safety pins. During use, it can ensure the firmness and stability of the connection of work attachments and prevent accidental detachment of work attachments, ensuring the safety of operators. Even in the case of failures in the oil circuit or circuit, safety devices can also play a protective role.
2)Reduce human operation errors: In the traditional process of replacing work attachments, manual operations such as installing and removing pins are required, which is prone to safety accidents due to human errors. The automated operation of the quick coupler reduces human intervention and reduces the safety risks caused by operation errors.
4.Protect equipment:
1)Reduce equipment wear: The quick and accurate connection method avoids unnecessary wear on excavators and work attachments during the replacement of work attachments, prolonging the service life of equipment. For example, traditional hard connection methods may cause wear to pin holes and other parts during installation, while the flexible connection of quick couplers can effectively reduce such wear.
2)Release internal stress: The quick coupler itself can rotate freely, which can release the internal stress generated in pipelines and connection parts during installation, avoiding damage to equipment caused by concentrated internal stress.
5.Good economic benefits:
1)Improve equipment utilization: Due to the ability to quickly replace work attachments, excavators can quickly switch between different work tasks, reducing equipment idle time and improving equipment utilization, thereby bringing higher economic benefits to users.
2)Reduce operating costs: On the one hand, it reduces the time and labor costs of replacing work attachments; on the other hand, it reduces the maintenance and repair costs of equipment because the wear of equipment is reduced and the failure rate is also correspondingly reduced.
