Uni-body Design
The excavator quick coupler adopts the un-body design, which is integrated processing and formed.
It is much more durable than separate welding parts.
Built with high toughness materials, the quick connector has outstanding cost performance with long service life.
Mechanical and Hydraulic type
The mechanical, or called manual excavator quick coupler offers a cost-effective option for mini excavators(1-9 ton).
They are easy to operate, no maintenance cost, and low failure rate.
The hydraulic type quick connector makes your work much easier.
It is equipped with an electric system to operate in the cab, and the independent hydraulic circuit confirms the reliable and safe operation.
The hydraulic type coupler is available to 1-45 tons.
Double Protection
The safety pin protection system ensures the quick coupler to work as usual in case of the cylinder failure.
The check valve protection system makes sure the regular work when the oil circuit is cut off.
