Characteristic:

Hydraulic transparent excavator trainer can simulate various actions of original excavator working unit. The executable components adapt the imported transparent organic glass hydraulic component, transparent nylon tube lap joint, working principle and hydraulic circuit working principle are clear at a glance. Whole trainer has the advantage of visual, intuitive, convenient and reliable, etc.

Training control unit also can adapt the independent relay control unit to electrical control. By comparison, extrude the superiority and advanced of PLC programmable logic control. Strengthen the understand and mastery of PLC programming unit.

Electric control unit adapt the PLC programmable logic controller control, it can realize the microcomputer intelligent control by PC microcomputer communication. In the meantime take the hydraulic circuit as the controlled member, strengthen the learning and application of PLC programmable logic controller.

Excavator trainer main consist of training bench, training stand, hydraulic component and electric appliance control component and programmable logic controller ( PLC ) and other component.

Main Function:

View and emulate, dismounting training of hydraulic transmission component and working principle.

PLC instruction programmable, ladder diagram learning experiment.

PLC and computer communication and online debugging.

The working training of excavator simulation function, bucket and bucket rod recombination.

Rotary, swing arm promote and platform rotation at the same time.

The learn and analyze of hydraulic control system principle.

When the discharging operation, bucket rod and bucket working, the big arm can be adjust the position height at the same time.

Return, platform rotation, swing arm and bucket rod can return the excavation starting position.

The learning and application of PLC programmable software.

The optimal experiment of application and control scheme of PLC in the hydraulic transmission control.
