The basic operation method of the excavator, how to operate the excavator tutorial

1. Right operating handle (right hand operation) to control the work of the boom and bucket:

The handle pulls back the boom to lift, and the handle pushes the boom forward to descend. When the track touches the ground, hold down the handle and push forward, and the excavator can be lifted. Moving the operating handle to the left is to fold the bucket, and moving the operating handle to the right to turn the bucket outward.

2. The left operating handle (left-handed operation) controls the forearm and rotation, the handle pulls the lower arm back to retract, and the handle pushes forward and the lower arm turns out. The operating handle is moved to the right and the excavator is rotated to the right, and the handle is moved to the left and rotated to the left. But many excavator operators will adjust the direction, which is what we call the positive and negative mobile phone.

It is to adjust the left operating handle, and after the adjustment, the forearm and the rotary action are reversed. All of you who just drive the excavator must ask the master to be the anti-mobile phone, and try it gently before operating. Do not act as a veteran excavator and pull the operating handle hard to avoid unnecessary accidents.

3 Walking pedal operation: push the excavator forward and pull the excavator backward to retreat. For quick steering, one can be pushed forward and pulled backward one by one.

The basic operation of the excavator: the basic operation of the excavator, this operation must be graduated from Lanxiang.

The excavator operation method is as follows:

Tool: Excavator.

1. Left handle operation.

Stick out of the forward ( ) stick; Backward ( ) stick retract; Left ( ) Left Turn; Turn right ( ) to the right.

2. Right handle operation.

Forward ( ) boom descent; Backward ( ) boom lifting; Left ( ) bucket reeled; Turn the bucket out to the right ( ).

3. Walking. The forward and backward movements of the left pedal are: turn right and turn left.

The forward and backward movements of the right pedal are: turn left and turn right.

The left pedal is forward, and the right pedal is backward: 360° clockwise rotation in place.

The right pedal is forward, and the left pedal is backward: 360° counterclockwise in place.

4. How to climb a flat truck with a small excavator (no ladder).

Adjust the angle of the excavator when getting on the car to ensure that the chain plate and the flatbed are aligned; Then turn the excavator to the right (one side of the cab excavator chain plate is vertical), support it with the excavator arm, and the excavator slowly climbs up. This process must be slow, while reversing while observing the adjustment, the faster the speed, the easier it is to deviate.

5. How to dig a T-shaped trench.

It is best to dig from the end of the T-shaped contact with the wall, if the soil quality is better, you can ride the trench to dig, note: do not dig the soil with the small arm when digging, which will lead to the excavator offset; Use a bucket to dig, trying to dig out the shape of the trench at once.

Here's how:

1. Hydraulic safety lock switch.

When you open the door of the excavator, you can see it. As the name suggests, "safety locks" are designed with the safety of the driver in mind. Since the action of the excavator is transmitted by hydraulics, the safety lock can control the transmission of hydraulic pressure in time.

When the excavator starts, the driver sits in the seat and turns the hydraulic safety lock to the unlocked state, and then the operating handle or walking pedal excavator will have corresponding actions.

2. The main switch of the power supply.

Before starting the excavator, be sure to check whether the excavator total source switch is turned on. When the excavator does not work for a long time, the main power supply needs to be turned off, which can prevent battery leakage. On the excavator, even if the key of the excavator is pulled out, the roof emergency lights and radio are still in a power-on state, and they can only be turned off when the main power switch is turned off.

3. Engine start switch.

When the driver enters the cab, insert the key through the keyhole and turn to the ON position, at this time the power is turned on, and when the instrument panel lights up, then turn to the start position, and the engine starts. When the temperature is cold, due to the increase of oil viscosity and the decrease of battery performance, it may cause difficulty in starting, so please try to start successfully at one time, and the empty motor enters the warm-up state.

I believe you can understand the process of turning on and shutting down, and what I want to say here is the importance of warm-up, which is precisely the process that most drivers will ignore. In general, the engine should be warmed up after starting, especially when the weather is cold and the water temperature is relatively low. Warm-up means to make the machine run first, wait for the machine temperature and the parts to "run in", and then let the machine enter the working state.

4. Dashboard.

The excavator can choose different working modes in the operation: S standard mode: H heavy digging mode; l Refurbishment mode; f Minor mode. Like other excavators, there is P H strong working mode, M S standard mode; e-economic model and so on.

5. operating the handle.

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 the operation, you need to consider the inertia of the excavator, you shake the handle, the excavator will start to rotate, and then release the handle, the handle is naturally centered after the excavator will continue to rotate due to inertia, so the distance of the shake operating handle should be considered when operating.

In addition, these two handles are used for the action of digging large and small arms and bucket telescopic movements, and the speed and strength of the action will change with the different swing positions. Due to the different models and brands of excavators, some excavator handles are equipped with function buttons that instantly increase power, such as increasing the strength of the large and small arms during hoisting, and increasing the speed of the large arms during loading operations.

Do you want to learn to drive an excavator? The old driver of the excavator gives you a little advice.

Hello, you can go find a master to teach it.

1. The operating lever of the left manual tool is used to operate the stick and rotate. How:

Push up: stick to keep the material;

Pull down: stick digging;

Pull to the right: the upper body turns to the right;

Pull to the left: get on the car and turn to the left;

Center: When the left-hand lever is in the center, the upper body does not rotate and the stick does not move.

2. The right-hand working device operating lever is used to operate the moving wall belt to accompany this and the bucket. How:

Push down: the boom descends;

Pull up: the boom is raised;

Push to the right: bucket to keep the material;

Pull to the left: bucket digging;

Neutral: When the right-hand lever is in the middle, the boom and bucket do not move.

The basic operation of the excavator, confirm the obstacles around the excavator, and learn to drive, first observe the surrounding vehicle conditions; After getting into the car, the horn is sounded first, which plays the role of warning passers-by, and also plays a safety warning;

Confirm that there is no alarm on the instrument and that there is no abnormal situation in the vehicle; Screw the shut-off valve to ON to start; Its specific operation is divided into four actions: boom, boom, bucket, rotation, and some small machines have a dozer blade.

1. Loading

Excavator loading.

Excavator loading is the simplest and most commonly used one in excavator operation. The operation skills of loading are as follows. First of all, the body should be in a horizontal and stable position, otherwise it is difficult to accurately control the rotary unloading, thereby prolonging the operation cycle time; Keep an appropriate distance between the body and the truck to prevent the tail of the body from colliding with the truck when making a 180-degree turn; Try to carry out left-turn loading, so that the field of vision is wide, the operation efficiency is high, and at the same time, the rotation angle should be correctly mastered to reduce the time used for rotation; The position of the truck should be lower than that of the excavator, so that the operator's line of sight will be better and more conducive to loading; Load the sand first, and then place the large rocks, which can reduce the impact on the trunk; In mines, you can also zoom in on the rocks first, which will prevent them from falling when walking on top of the truck's large box.

2. Excavation

Excavator buckle stone.

Effective excavation methods can reduce the excavator's. Wear and tear can also improve work efficiency. For example, when the bucket cylinder and the connecting rod, the stick cylinder and the stick are 90 degrees to each other, the digging force is the largest; When the bucket teeth are kept at an angle of 30 degrees to the ground, the best digging force is the least soil cutting resistance; When digging with a stick, make sure that the angle of the stick ranges from 45 degrees in the front to 30 degrees in the back.

The use of both boom and bucket increases digging efficiency.

In mines, excavators pick stones, which is also the most common. Digging hard rock can cause a lot of damage to excavators, especially buckets, but sometimes it's unavoidable. How to use the bucket to reduce the wear and tear of the excavator?

The position of the excavator should be adjusted according to the crack direction of the rock, so that the bucket can be shoveled in smoothly and excavated; Insert the teeth into the cracks in the rock and dig with the digging force of the stick and bucket. At this time, you should be especially careful not to use too much force, otherwise, the root of the tooth will be easily broken.

3. Crushing

Excavator crushing ore.

The breaker is also very commonly used in excavators, whether it is in the demolition of houses or in mines, it is widely used. So, how to use the breaker well? The first thing to do is to place the hammer head vertically on the object to be crushed.

When starting the crushing operation, first lift the large and small arms. When crushing, the crushing chisel rod should be pressed on the crushed object all the time, so that the cylinders of the large and small arms are stretched out, which can reduce the damage to the cylinder. Since vibration will gradually change the direction of the hammer, the bucket cylinder should be adjusted at any time so that the direction of the hammer is perpendicular to the surface of the crushed object.

When the hammer head cannot enter the crushed object, the crushing position should be changed; In some places, do not continue to break for more than 20 seconds, otherwise not only the hammer head will be damaged, but also will cause great damage to the piston and cylinder of the hammer; For hard objects, they should be broken gradually starting at the edges. If the broken object has already been broken, then the crushing should be stopped and the air striking should be avoided.

Common operations require more technology, and I believe that many machine operators will have such feelings. Especially in the construction of mines, the work efficiency and the minimum damage to the machine can be reflected in the most basic operation.
