Quick Coupler is another name for an excavator rapid connector. The Tilting Quick Coupler is one of them, and it can rotate around 180 degrees, allowing the operator to position the accessories more precisely without having to reposition the machine. As a result, overall productivity and versatility are enhanced.


Excavator quick replacement joints can quickly install various configuration accessories on the excavator, such as buckets, soil loosening devices, crushing hammers, hydraulic shears, wood grabbers, stone grabbers, and so on, allowing the excavator's scope of application to be expanded, time saved, and work efficiency to be improved.


Quick connectors for excavators are divided into three categories.

 

The mechanical and hydraulic types of excavator quick connectors are different.

 

 

A brief overview of the excavator quick linker

 

The use of high-strength materials, such as 20M high-strength board in Korea and Q345B board in China.

 

Suitable for all tonnages ranging from 4 to 50 tons.

 

To assure safety, a liquid control check valve safety mechanism is used.

 

Excavator configuration parts do not need to be reconnected, and the pin shaft does not need to be removed; as a result, installation is quick, and work productivity is considerably improved.

 


The hydraulic type rapid change joint's working concept is as follows:

 

The oil cylinder is primarily responsible for locking and unlocking the hydraulic quick change joint on pin shafts 1 and 2. The oil cylinder is retracted, and the hook press block is moved from position 1 to position 2 when the functioning parts need to be replaced. The fast change joint is removed, and other operational parts are installed in its place. The oil cylinder is opened again when the hook press block has been aligned with the pin shaft, and the hook press block is moved from position 2 to position 1, locking the pin shaft of the working parts. Of course, this is in addition to the exterior oil and solenoid valves operating simultaneously.

 

 

The mechanical rapid change joint's principle of operation

 

Domestic mechanical quick joint manufacturers' products are primarily classified into two types, one bolt type and one screw type.

 

When replacing parts on a bolt type, for example, first remove the wedge card, which will knock down the interior, and then tighten the T buckle (T buckle can be smoothly the red part press block to recycle, here in the face of the welding requirement is higher, slide rail welding not level off, at the same time polishing not clean, red briquetting action hard to smooth.) The bucket's quick connector has been disconnected. The T-buckle is pulled back and the wedge card is put into the T-buckle to lock it in place when the needed functioning part is changed.
