Excavator loader accessories PC200-6 LS feedback valve 708-2L-04713

In view of the existing problems of safety, reliability and easy cracking in the locking process of excavators, a locking scheme is provided for excavators with engine iii of assembly country. The specific technical scheme is as follows:

An excavator locking system, applied to an excavator with an assembly Country iii engine, comprises a body controller, an engine controller connected to a body controller signal, and the body controller comprises:

Input module for receiving locking instructions;

The locking level judgment module is connected with the input module and used to judge the locking level corresponding to the locking instruction;

The status acquisition module is used to collect the operating status of the excavator;

The locking execution module connects the locking level judgment module, status acquisition module, excavator main pump and engine controller, determines the output result of the locking level module and the operation state of the excavator collected by the status acquisition module, and outputs the locking execution instruction to the excavator main pump and/or the engine controller.

Better, in the excavator locking system, the status acquisition module includes:

The first acquisition unit is used to judge whether the excavator is in working state;

The second acquisition unit is used to determine whether the excavator is in a walking state.

Better, in the excavator locking system, the locking level corresponding to the locking instruction includes:

The first locking level, the locking execution instructions of the first locking level include:

When the excavator is in a walking state, the speed of the engine of the excavator is limited, the displacement of the main pump of the excavator is not limited, and

When the excavator is not in a walking state, the speed of the engine of the excavator is limited and the displacement of the main pump of the excavator is limited;
