Excavator important button switch introduction

First, hydraulic safety lock switch
When you open the door of the excavator, you can see it. The "safety lock", as the name suggests, is designed with the safety of the driver in mind. Since the action of the excavator is driven by hydraulic pressure, the safety lock can control the hydraulic pressure transmission in time. When the excavator is started, the driver sits on the seat and turns the hydraulic safety lock to the unlocked state, at which time the operation handle or walking pedal excavator will have the corresponding action. When the excavator is not working or the driver wants to get out of the car, the hydraulic safety lock should also be turned to the locked state to avoid safety accidents caused by accidental touching of the tentacle handle and walking pedal.

Hydraulic safety lock switch
Of course, different brands of excavators, their hydraulic safety lock Settings are different, but "change the soup does not change medicine", as long as we know it, to a certain extent, we can skillfully control it. I opened a Xugong 60E before, and after the safety lock was locked during the operation of this excavator, the operation handle could not move, and the strange thing was that the walking pedal could still operate. Here also hope that everyone in the operation should develop good operating habits, in the process of operation always have safety awareness.

Two, the main power switch
Before starting the excavator, ensure that the main source switch of the excavator is turned on. When the excavator does not work for a long time, it is necessary to turn off the total power supply to prevent battery leakage. On the excavator, even if the key of the excavator is pulled out, the roof emergency light and the radio are still in the power state, and only the main power switch can be turned off. It is also a good habit to turn off the main power switch after work every day.

Three, engine start switch
The engine start switch is actually the position where the key is inserted to start the excavator. There are some signs on it. Let's get to know it.
(1) START, we can understand the meaning of start, start.

(2) ON, we can understand the meaning of connected and opened, when the key is turned here, the excavator circuit is connected.

(3) OFF, we can understand the meaning of disconnect, close, when the key is turned here, the excavator circuit is disconnected, and the key can be inserted and removed.

(4) HEAT, we can understand the meaning of warming the machine, when the temperature is low, the key is turned here to warm the machine.

Engine start switch

When the driver enters the cab, insert the key from the keyhole, and turn to the ON position, at this time the power is on, after the instrument panel lights up, then turn to the START position, at this time the engine starts. When the temperature is cold, due to the increase of oil viscosity and the reduction of battery performance, it may cause difficulties in starting, so please try to start successfully once, and the idling engine enters the warm state.

The power-on and shutdown process is believed to be understood at a glance, and what is to be said here is the importance of warming the machine, which is precisely the process that most drivers will ignore. Under normal circumstances, the engine should be warmed after starting, especially when the weather is cold and the water temperature is relatively low. The meaning of warming the machine is to first make the machine run, to "run in" between the machine temperature and the components, and then let the machine into the working state.

Warm up is a necessary method to protect the machine, otherwise, it is likely to cause cylinder burst or piston wear is too large, just like the "warm-up exercise" before intense exercise. The process of warming the machine is about 5 minutes, and you can also use this time to butter various parts of the excavator. Of course, now most excavators can show the heating process in the dashboard, and there are indicators to remind us, then we will understand the signs on the dashboard.

Four, the instrument panel
For example, the excavator is regarded as a notebook, if the engine is the "motherboard" of the excavator, then the instrument panel is the "display" of the excavator, which can always give feedback on the status information of the excavator, such as fuel oil amount, cooling water temperature, oil temperature, engine speed, working mode, time, equipment maintenance information, fault inquiry, and so on.

Excavator instrument panel

Of course, the instrument panel and display content of each brand model are different, there are liquid crystal display and digital display.

With the continuous progress of science and technology, the function of the display is more and more, I have touched a Shanhe intelligent 230E before, and there is a "loading timing mode" in the display screen, which feels very suitable for loading operations.

Loading time setting

Mention the dashboard has to mention the camera device, like the European and American excavator, the rear camera has become the standard. You can have a systematic understanding of the overall status of the excavator through understanding and hands-on control of the dashboard, and there are many ICONS on the dashboard. Here, Xiaobian will understand these signs on the instrument of Shanhe Intelligent 230E.

The excavator can choose different working modes in the operation: S standard mode: H redigging mode; L Repair mode; F Minor repair mode. Like other excavators, there are P/H strong working mode, M/S standard mode; E Economic model, etc.

5. Operation handle
The operation handle is believed to be the most familiar, divided into about two. There are two methods of operation in China: because of the different Settings of the left operation handle, it is divided into forehand and backhand. The positive finger is the left and right rotation direction, and the backhand is the up and down rotation direction.

Most excavator glass will also be affixed with a nameplate to tell you the simple operation method, but it is still far from enough to be used for work. The operation of the handle of the excavator is different from that of the car, and the handle is in the center position in the natural state. For example, when rotating operation, it is necessary to consider the inertia of the excavator, you shake the handle, the excavator will start to rotate, and then loosen the handle, the handle is naturally centered after the excavator will continue to rotate due to the inertia, so the operation should consider the distance of shaking the operating handle.

In addition, the big arm of the excavation and the telescopic action of the bucket are the use of these two handles, and the speed and strength of the action will change with the different swing position. Due to the different types and brands of excavators, some excavator handles are equipped with functional buttons that increase power instantaneously, such as increasing the strength of the big arm during hoisting and increasing the speed of the big arm during loading.

Six, walk pedal
Here, the walking pedal is separated, and it is also an operation to be used in the work. Compared with the operation of the handle, the operation of the walking pedal is much simpler.

Excavator walking operation diagram

Below you can have a model of the excavator in your mind, imagine that the excavator is upright, the driving wheel is behind the cab, the left pedal is pushed forward, and the excavator is turned right; Right pedal forward, excavator left. The two pedals push forward or pull back at the same time to control the advance or retreat of the excavator. However, in the actual operation, it is necessary to integrate the action of the walking pedal and the operating handle, such as how to "over the wire", "on the trailer" and so on. Xiao Xu will explain in the next operation article.

7. Seat adjustment and seat belt use
In daily work, adjusting the seat and then operating can alleviate the driver's fatigue to a certain extent. General excavator seats are suspended vacuum seats, what is a vacuum seat? There is a regulating valve under the seat to adjust the vacuum pressure of the seat buffer according to the driver's weight.

The height and tilt of the seat back can be adjusted through the adjusting handle under the seat. The seat belt is fastened in the same way as in a car, pulling the seat belt out in front of the driver's chest and inserting the hook into the latch.

Seat belt latch

Although the seat of the excavator is equipped with a safety belt, it is virtually useless. Xiaobian has not seen the driver of the excavator wearing a safety belt, perhaps because the speed of the excavator is not as fast as that of the car. Perhaps because of an emergency, the driver is not easy to escape without wearing a seat belt.

Is that really the case?

Safety accidents of excavators also occur from time to time. Will the results be different with and without seatbelts? I hope that everyone can clearly understand the importance of safety belts, and cultivate their own safety awareness in the operation.

The importance of seat belts in cars

I used to drive the excavator to work on the ramp, one foot is pushed on the glass to keep balance, you are like that? Is this really safe?

Eight, other switches
In addition, there are other switches, such as the switch on the air conditioning panel and the radio panel, the wiper spray switch, the lamp switch and so on.

The setting of air conditioning and radio improves the driving experience to a certain extent, and the original excavator can also be "tall".

Excavator right control console

Wiper switch and lighting switch are indispensable in rainy days and night work, and there is a spare roof light switch at night.
