1. Demonstration control experiment of hydraulic loading machinery

1) For loading operation, after the bucket is loaded, the rocker cylinder extends to make the bucket reverse and the boom lifts;

2) Unloading operation, bucket unloading (the rocker arm retracts to make the bucket turn), and the boom descends.

2. Programmable controller (PLC) electrical control experiment: machine-electric-hydraulic integrated control experiment.

1) PLC instruction programming, ladder diagram programming learning;

2) Learning and using PLC programming software;

3) Communication and online debugging between PLC and computer;

4) The application of PLC in hydraulic drive control and the optimization of the control scheme.
