types

Different excavator quick coupler types:
There are many brands excavator quick couplers all over the world. Different brand manufacturers have different products designs. Generally speaking, we can classify them two types. They are manual type and hydraulic type.

For manual type excavator quick coupler, it is often for mini or small excavators and diggers, which the human power can operate it. While changing the excavator attachments, the operator need to open the lock on the quick coupler by hand power with a spanner. Although it is by human manual, but it is like semi-auto, it is very convenient to change the attachments, comparing to remove all the connect pins on the arm .And especially, it doesn’t install any hydraulic hose or pipeline while install the quick coupler for the excavators.

For hydraulic type digger quick coupler, It can cover all the capacity of the excavators. And the attachments exchanging job can be finished sitting in the excavator cabins very quickly. It will be a little bit complicated to install hydraulic type excavator quick coupler comparing to manual type quick coupler. Some hydraulic hoses and controller need to be installed on the excavators in advance.

certificate

Push Type
The push type is the one in which a cylinder pushed the pin and guarantees easy use due to the wide coverage range between the pin and pin.
