Any mechanical equipment will fail or be damaged after a certain period of use. In the event of a failure, it is not necessary to find a maintenance person to repair it immediately. Some failures can be handled by themselves. For example, some failures of the digger grapple can be self-checked and dealt with.

After the excavator is equipped with a digger grapple, the advantages in forest operations are obvious, and the loading and unloading efficiency is doubled. Various failures may occur after the digger grapple is used for a stage. Here is an analysis of several common failures and treatments for everyone:

1. The digger grappler cannot rotate 360 degrees:

First, check whether the rotary solenoid valve is energized, and whether the rotary oil inlet and return pipes are energized. If there are no problems with the above items, please check whether the rotary motor is working properly, the motor is normal, and the solenoid valve does not work under power, please replace the solenoid valve or clean it in time Solenoid valve core.

Circuit and switch check whether the fuse and relay are off.

2. The digger grapple has no gripping action:

Check whether the gripping pipeline is oiled. If there is hydraulic oil, check whether the stroke valve on the cylinder is stuck. If stuck, clean the cylinder spool, check whether the cylinder rod is deformed or broken, and check whether the solenoid valve that opens and closes is normal. Check whether the relay is burned out, if so, please replace the above accessories in time.

3.The digger grapple is weak:

Check whether the pipeline and shut-off valve are fully opened, whether the solenoid valve can be fully opened, whether the oil cylinder seals are worn and leaked, if the above problems occur, please correct or replace the seals in time.

Most of the failures are caused by carelessness during use and carelessness after use. Therefore, you should pay more attention to the digger grapple of the equipment at ordinary times, so as not to shorten the service life of the machine too seriously.
