Comparison of quick hitch and no quick hitch coupler

The quick hitch coupler of the excavator, also known as the quick-change joint, is installed at the front end of the excavator’s working device. It can realize various excavator attachments such as buckets, breakers, rippers, hydraulics without manually disassembling the pins. The replacement of shears, wood grabs, stone grabs, etc., enables the excavator to expand various operations such as crushing, shearing, cleaning, compaction, milling, pushing, pinching, grabbing, scraping, loosening, hoisting, etc. The attachment replacement process is easy to operate, safe and reliable, saves time, and greatly improves the working efficiency of the excavator.

一.Classification of quick hitch couplers for Excavators

Divided by product structure and functional level, quick hitch couplers can be divided into two categories. One has a simple structure and only has the function of quick-change connection, which is called ordinary quick-change; the other type not only has quick-connect function, but also adds attributes. With freedom, it is called universal quick connection. Only the ordinary quick hitch coupler is introduced here.
