1, Use material ofhigh hardness.Suitable for differentmachines of 4-45ton.
2, Use security deviceof hydraulic control valve to ensure the safety.
3, Can change theaccessories without disassembling the pin and axle.
Thusreslize faster installation and much higher efficiency
Quick coupler also called quick connectors,mainly to improve the efficiency of the replacement work in progress when theexcavator bucket and bucket conversion , ripper , etc. between the components ,it divided into hydraulic and mechanical, although the design is very flexibleand subjective thing , the manufacturers of the products look different , butthe basic principle is the same .
Hydraulic quick coupler works:
Hydraulic quick coupler cylinder action relymainly on the fixed and loose pin 2 release . When circumstances requirereplacement parts , fuel tanks recovered from the position of the moving hookbriquetting 1 to position 2 , the quick coupler from , switch to the otherworking parts , after briquetting good hook pin , cylinder and then open , hookclamps from position 2 to the movement of a position of the lock pin fittingwork . Of course, this except there is an external oil line and solenoid valvessimultaneously.
Mechanical quick coupler works:
Mechanicalquick coupler major domestic manufacturers of the products it two, one bolt Ascrew . To bolt , for example, when the working parts need replacement , thefirst wedge card out , the T -shaped buckle inwards knock , (T -shaped bucklecan be very smooth to drive the red part of the briquetting recovery, where theface of relatively high welding requirements , not welded rails smooth , but thepoint is not clean , then polished , smooth red portion briquetting actiondifficult . ) quick coupler and bucket out . When the required change to theworking parts , T -shaped buckle pull back , wedge card into the T-shaped bucklelock.
The most important thing is quick coupler outquickly , grasping pay working parts , as well as stable and effectively lockthe working parts .
