What should I pay attention to when driving an excavator? Excavator safety precautions

In terms of safety, there are three main aspects: 1In the air, do not touch wires, buildings, construction site personnel, etc., but also prevent falling objects from falling into the air from hitting the top of the machine; 2.

The machine itself, always pay attention to the surrounding environment, steep slopes, quagmires, and rivers are dangerous; 3.Underground, the main thing is not to dig through the gas pipeline! It's better to dig up the water pipe and communication pipe, and it is very easy to cause disasters if you dig the gas pipe.

The machine must be inspected and buttered added every day (some excavators do not need to add butter every day).The content of daily maintenance is on the manual, and will not be repeated. During the work process, it is best to move consistently and gently, and try to avoid emergency stop and rapid movement to protect the hydraulic system and the engine The engine is best to warm up before working, and then increase the load after the water temperature rises.

It is also necessary to idle for about 10 minutes before stopping to protect the engine. In the process of work, it is necessary to pay close attention to the changes of each instrument, and in case of alarm, immediately stop the machine for inspection and repair. Experience is accumulated by oneself, and it will be remembered only when you encounter it.

Young you have to work hard, how long knowledge, knowledge, more than a technician, but also a little more capital, don't give up the popular industry, I am a professional operator, I can afford you, remember safety first, **.

Excavator safety precautions

First, each time the excavation should not be too deep, and the bucket should not be too violent, so as not to damage the machinery or cause an overturning accident. When the bucket falls, be careful not to impact the track and frame.

Second, with the excavator operation, the bottom clearing, leveling, slope repair personnel, must work within the radius of the excavator. If it is necessary to work within the radius of rotation of the excavator, the excavator must stop and rotate and brake the rotation mechanism before working. At the same time, the crew on and off the plane should take care of each other and cooperate closely to ensure safety.

Third, within the scope of excavator loading activities, vehicles and pedestrians shall not be stopped. If you unload the car, you should wait for the car to stop and the driver leaves the cab before turning the bucket and unloading the car. When the excavator rotates, try to avoid the bucket from going over the top of the cab.

When unloading, the bucket should be lowered as low as possible, but care should be taken not to collide with any part of the car.

Fourth, when the excavator rotates, the rotary clutch should be used to cooperate with the brake of the rotary mechanism to rotate smoothly, and sharp rotation and emergency braking are prohibited.

Fifth, the bucket has not left the ground, shall not be turned, walking and other actions. When the bucket is fully loaded and suspended, the landing boom and walking are not allowed.

Sixth, when the crawler excavator moves, the boom should be placed in the forward direction of the walk, and the bucket is not more than 1 meter from the ground. And brake the slewing mechanism.

Seventh, when the excavator goes uphill, the driving wheel should be behind, and the boom should be on it; When the excavator is going downhill, the drive wheels should be in front and the boom should be behind. The slope shall not exceed the twelfth, and the arm should fall to the ground when the maintenance, overhaul, lubrication and replacement of the pulley at the top of the boom. Excavator Ann.

1.Check before the operation to confirm that everything is complete and intact, and there are no obstacles and other personnel within the movement range of the boom and bucket, and the operation can only be carried out after the horn is sounded.

2.The excavator cab is exposed to the transmission part, and a protective cover must be installed.

3.The electric single-bucket excavator must be well grounded, and the oil circuit and cylinder of the boom of the hydraulic transmission must be confirmed to be in good condition.

4.When the front shovel is operating, the working face should not exceed the maximum excavation height and depth specified in the performance of the machine. In dragline or backhoe operation, the distance between the excavator track or tire and the edge of the working face shall not be less.

5.The excavator works on flat ground, and the tracks (or tires) should be braked with brakes. Wedged.

6.Excavators are suitable for use in clay soils. Gravel soil.

Shoveling and excavation of soils such as peat rocks. After blasting and digging loose'When digging in heavy rock, only the front shovel is allowed, and the rock diameter should be less than 1 2 of the width of the bucket mouth. It is forbidden to use any part of the excavator to break the stones.

permafrost, etc. 7.Take the soil. There shall be no obstacles in the unloading of the soil, and no one shall stay within the radius of the bucket operation during excavation.

When loading the operation, it should be carried out after the transport vehicle is stopped, the bucket should be lowered as much as possible, and the vehicle should not be smashed, it is strictly forbidden to have people in the box, and it is strictly forbidden to cross the bucket from the top of the car cab. When unloading, the bucket should be lowered as low as possible, but it should not hit any part of the car.

8.When walking, the boom should be parallel to the track, and the brake slewing mechanism, the bucket should be 1m from the ground. The walking slope shall not exceed the maximum allowable slope of the machinery, and the downhill shall be driven at a slow speed, and it is strictly forbidden to slide in neutral gear. The turn should not be too fast, and the cushion should be reinforced when passing through soft ground.

9.When the excavator slewing brake, the slewing brake should be used, and the steering clutch should not be used to reverse the braking. When fully loaded, it is forbidden to turn sharply and brake sharply, and the bucket should not rise and fall too violently during operation. When falling, the frame or track and other parts shall not be impacted, and the lifting wire rope shall not be relaxed.

10.When operating, the fuselage must be stopped before digging, when the bucket does not leave the working surface, it shall not be rotated and walked, and the fuselage shall not be lifted and landed when the fuselage is rotated or the bucket is loaded.

11.When excavating on the edge of the cliff, there shall be no umbrella edge and loose large stones on the working surface, and the excavator should be immediately dealt with or evacuated to a safe area when it is found that there is a danger of collapse.

12.When the dragline is running, the bucket shall not continue to eat soil after it is fully loaded, and shall not be overloaded. Pull the shovel as a ditch.

When working on river channels and other items, it should be based on ditches. The depth of the river channel. Slope and soil quality to determine the safety distance from the slope edge, generally not less than 2m, backhoe operation, must wait for the boom to stop and then eat soil, bucket, stretch out the head should not be too violent.

Too big. 13.When driving the driver out of the operating position, the bucket must hit the ground and the engine shut down, regardless of the length of time.

14.Buckets are not allowed to lift materials.

15.When abnormal operation is found, the machine should be stopped immediately, and the operation can be resumed only after the fault is eliminated.

The conditions required to drive an excavator are education, age, physical fitness, etc.

1. Academic qualifications. The education must reach junior high school, and now no matter what work you do, you need to look at the academic background, and driving an excavator is no exception. Because it is not a light job, the requirements for academic qualifications for driving an excavator are relatively low, as long as the education is in junior high school and above.

2. Age. Between the ages of 18 and 59, there is also an age limit for digging, and you must meet the requirements to drive an excavator. Persons under the age of 18 are minors and do not participate in the workforce, while persons over the age of 59 are too old to respond in a timely manner when such thoughts arise.

3. Physical fitness.

If there are no physical diseases such as heart disease and high blood pressure, it is very likely that you will get sick during the work process, which will lead to the delay of the entire construction site project. Therefore, people with some physical diseases are also not allowed to do this work.

Introduction to the excavator:

As a kind of excavation machinery, excavator is an earth-moving machine. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators have become one of the important construction machinery in engineering construction. The excavator is a heavy construction machine, and the equipment is very high.

Certificates required to drive an excavator:

To drive an excavator, you need to hold a special vehicle driver's license, also known as an operating license. Because the excavator driver's license is a special vehicle driver's license, you can't drive an excavator without this certificate. Because excavators are heavy construction machinery, there are a lot of precautions when driving.

Application materials required for the excavator operation certificate:

5 one-inch color on white background**.

The original ID card and 3 copies of the positive and negative difficulties.

1 copy of the registration application form.

1 copy of technical secondary school or above. <>

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

The flatbed truck without a ladder on the small excavator is very easy to be crooked, resulting in the more and more crooked when reversing in the back. In fact, this problem is easy to solve: adjust the angle of the excavator when getting on the car to ensure that the chain plate and the flat car 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.

2. How to dig a T-shaped trench.

The so-called T-shaped ditch is to dig a trench to focus on the wall, and such a trench is more difficult to dig. It's best to dig from the end of the T-shaped contact with the wall, and don't panic when you encounter this kind of thing, because in addition to riding on the ditch to dig, everyone will dig wide.

If you encounter sand, it is not recommended to ride on the ditch to dig, which is easy to be dangerous. If the soil quality is better, you can ride the trench to dig, it should be noted that: do not collect the soil strongly with the small arm when digging, which will cause the excavator to deviate; Use a bucket to dig, trying to dig out the shape of the trench at once.

3. How to level the ground.

Regarding leveling, this is the most basic operating skill of the driver. Leveling is not a set of theories that you can master, it takes a lot of practice, when leveling the movement should be slow, how slow you can dig, how long you can dig, how long you can dig, and then slowly scrape through the soil with the tip of a shovel.

So how do you look at the uneven? If it feels high, scrape it slowly, and when it is low, push a little dirt with the tip of the bucket. In this way, step by step, you will always grasp a reasonable and flat perspective.

It should be noted that the excavator must be stopped and leveled, if you are working on the mound, you need to move the excavator left and right so that the bucket is parallel to the ground.

4. How to load the truck quickly.

I'm loading too slowly, how can I load it fast? Many friends have encountered this problem, here is a little trick.

The first is that the excavator should stop steadily, so that it is fast and stable when turning.

The second is to minimize the movements, which can reduce one to one. When excavating the soil, the bottom of the bucket is as parallel as possible with the soil layer, and then the small arm shovels the soil, and this action can dig more and dig more full. When throwing soil on the car, try to lift the big arm and dump the bucket to unload the soil, do not push the small arm, because then the soil piled on the bucket will fall down in advance.

1. Is the excavator easy to learn?

All I can say is that excavators are not difficult to learn. As long as the excavator is more basic to master, then it is easier to operate, but to achieve a certain level of proficiency, you also need to practice more and accumulate experience. The key to learning excavator operation technology is to watch more, listen more, pay more attention, and repeatedly learn and study various operation skills.

Don't be afraid to make mistakes, and find more problems. The small mistake now is to avoid the same mistake in the future, and when others encounter the same mistake, you can point it out in time, so that others will be impressed by you.

2. How long does it take to study in excavator school and how much is the tuition fee?

How long is the right time to learn excavators in school? Now many excavator training schools have lengthened the excavator training cycle, there are half a year for a semester, a year for a semester, and even a two-year semester system, not only that, but also increased the tuition and miscellaneous fees to more than 10,000 yuan. And some excavator schools also link excavator training and academic qualifications, which is called beautifully:

Academic qualifications plus skills. In this way, it is kind of ridiculous.

The students must understand that the excavator is a short-term training, and the excavators learned in school are more basic actions. And experience - this more important content cannot be learned in any excavator school.

Therefore, under normal circumstances, it is completely okay to study in the excavator school for one to four months (the teaching arrangements of different schools are different, and the time will be different), and then contact the internship opportunity through the excavator school, and practice on the construction site for another one to three months, so that both technology and experience are enough to meet the general construction requirements. The reason why some schools extend the study time is to make profits during the student's study, and it costs money to eat and live in the school, so students must keep their eyes open when choosing.
