Hydraulic safety lock switch for excavator
When opening the door of the excavator, you can see it. "Safety lock" is designed to take into account the safety of the driver. As the action of the excavator is hydraulically driven, the safety lock can control the hydraulic 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 this time the operation handle or the walking pedal excavator will have the corresponding action. When the excavator does not work or the driver wants to get off, it should also turn the hydraulic safety lock to the lock state, avoid the failure to touch the handle and the walking pedal for safety accidents. When the bucket was rotated into the air, because of thirst, the little knitting turned to hold the mineral water after the seat, and the left operation handle was touched. The excavator began to turn. Fortunately, it was "remedied" in time, but the bucket touched the tail of the dump car, and did not cause the loss. But after this time, the little editor was no longer the same. Dare to "take a risk" to do such a thing.
Of course, different brand excavators, the hydraulic safety lock setting is different, but "change soup does not change medicine", as long as we know it, to a certain extent, we can control it skillfully. Before the small editor opened a Xugong 60E, this excavator is very not "thick", when the operation will lock the safety lock, the operating handle can not move, strange. It is also a walking pedal that can be operated. Here, I hope you should develop good habits in homework and always have safety awareness in the course of homework.
Total switch of power supply for excavator
Before starting the excavator, be sure to check whether the total source switch of the excavator is open. When the excavator is not working for a long time, it is necessary to close the total power supply to prevent the battery leakage. On the excavator, even the key of the excavator is pulled out, the emergency lamp and the radio on the roof are still in the state of electricity, only the power switch is closed. It can be completely closed. It is a good habit to turn off the power switch after work every day.
Starting switch of engine for engine of excavator
The engine start switch actually means inserting the key to start the excavator's position. There are some signs on it. Let's get to know it.
1, START, you can understand the meaning of starting and starting.
2, ON, you can understand the meaning of connecting and opening. When the key is transferred to this place, the whole circuit of the excavator is connected.
3, OFF, you can understand the meaning of disconnecting and closing. When the key is transferred to this place, the circuit of the excavator is disconnected and the key can be inserted.
4, HEAT, you can understand the meaning of warming up, when the temperature is low, turn the key to the warmer.
When the driver enters the cab, the key is inserted from the keyhole and turned to the ON position. At this time the power is connected, and then the instrument disc is turned on and then to the START position. At this time the engine starts. When the temperature is cold, the engine oil viscosity increases and the battery performance is reduced, the starting difficulty is possible. Therefore, please start up as much as possible. Success, turn the engine into the warmer state.
The process of turning off the machine is believed to be understood by everyone. Here is the importance of the warm machine. It is the process that most drivers will ignore. In general, the engine should be warm after the engine is started, especially when the weather is cold and the water temperature is low. The idea of the warm machine is to make the machine run first, wait for the machine temperature and the one. It is a necessary way to protect the machine. Otherwise, it is likely to cause the cylinder burst or the piston to wear too much. It is like the "warm body movement" before the violent movement. The warm machine can be used for about 5 minutes, and can also use this time to butter the excavator. Now, most excavators can display the warming process on the dashboard, and there are indicators to remind them. Next we will find out the identification of the dashboard.
The operation and understanding of these switches for the experienced teacher to tell the knowledge, but also should be properly scruples of novice and friends who want to know about the excavator. Of course, you may think that the switch is not only these, there should be a clay pad and a broken hammer. In the next article, the small editor will be based on its own. Experience to talk about the operation of the earth plate and the broken hammer.
