How to use mechanical quick change for mini excavators

Mechanical quick change, fixed by manually tightening the top screw with a wrench, usually used on small excavators.

Due to the different operating conditions of excavators, it is often necessary to install and switch various working devices on excavators, such as excavators, crushing hammers, wood grabbers, scarifiers, etc. This type of accessory that can quickly replace the working device, called a quick connector, can quickly disconnect and install various accessories, and can stably and effectively lock the working device. It improves the replacement efficiency of small excavators for replacing accessories such as excavators, crushing hammers, and spiral drills.

Working principle of mechanical quick change

By rotating the mechanical screw to adjust the distance of the movable block, the ability to disassemble and install the working components of the excavator is achieved.
