Many people are curious about why the excavator can have such a flexible movement, like a human arm, by using a few poles in the cab to operate this monster?
Today, Ah Xiang is going to reveal the secret to you. As long as you learn the following 8 movements, everyone can dig a machine.
There is an operating lever on both sides of the driver's seat of the excavator, and all the movements of the excavator "arm" and the fuselage are done by the 8 movements of the two operating poles.
4 movements of the left operating rod
Push left: the excavator fuselage revolved to the left
Push right: the excavator fuselage rotates to the right
Push forward: protruding the arms
Backward push: the retracting of the arms
4 actions of the right joystick
Push to the left: the shovel comes to the inside
Push to the right: the bucket goes out
Push forward: the drop of the arm
Backward push: lift up the arm
The 8 directions of the two joysticks can control the "arm" movement of the excavator and rotate, but the excavator will still have to walk in addition to the "arm", which requires two other manipulators to control it.
Look, the two joysticks in front of the seat are connected with the pedals below. They can be pushed and pulled by hand or pedaled by foot.
Left lever forward: left track
Left operating rod backwards: left track back
Right lever forward: right track
Right lever backwards: right track back
These two joysticks can control all the movements of the excavator. Let's give an example.
The excavator goes straight: two operating poles push forward at the same time
The excavator backwards: two operating poles pull back at the same time
The excavator turns left: the right lever pushes forward and the left lever stays stationary or backward.
The right turning of the excavator: the left lever moves forward and the right lever stays stationary or backward.
How, is it easy to learn to open a excavator? It is also necessary to add that the driving habits of the excavators in different areas are different, so the excavators will be transferred to two modes of "forehand operation" and "backhand operation", and the forehand operation mode is described in front of us, and the following is to talk about the backhand operation mode.
4 movements of the left operating rod
Push to the left: protruding the arms
Push to the right: the arm retracted
Push forward: the excavator fuselage rotates to the right
Push back: the excavator fuselage revolved to the left
4 actions of the right joystick
Push to the left: the shovel comes to the inside
Push to the right: the bucket goes out
Push forward: the drop of the arm
Backward push: lift up the arm
The difference between backhand operation mode is that the rotation operation and the movement of the arm are interchanged on the left lever.
How, the big guy of excavator is actually not complicated. These movements are the basic work of the excavator, which can not be qualified as a qualified driver. The qualified excavator driver also needs to combine these movements, make the excavators smooth and smooth, and complete the different construction requirements.
This is like we learn to drive, the light will not play the direction, the light will not shift, it can be able to control the direction of the oil with smooth shift in order to be able to drive!
