Purpose and characteristics
Due to the different working conditions of excavators, frequent replacement of working devices, such as buckets, breakers, and wood grabbers, is often required. Our company has developed a device that can quickly replace the working device, which is called a quick connector, also called a quick-change joint, which can quickly disengage and install the working device, and can lock the working device stably and effectively. It improves the replacement efficiency of excavators to replace buckets, breakers, rippers and other working devices.

The hydraulic excavator quick-change joint produced by our company is driven by a hydraulic cylinder, The hydraulic control one-way valve is locked, and the electromagnetic reversing valve controls the release and clamping;

at the same time, the hydraulic cylinder controls the length of the distance.

so that the clamping can be adjusted steplessly. which can adapt to different working devices. The quick connector is very efficient, practical and convenient to use, and the excavator driver does not need to leave the cab, and directly controls the quick connector through the pilot valve to replace the excavator working device.
