What should be paid attention to in an excavator 30, what should an excavator pay attention to

1.Before the operation, identify the bright and dark obstacles in the site and mark them, and the obstacles can only be operated after they are cleared, and it is strictly forbidden to operate within 1m from the cable.

2.It is strictly forbidden to touch the rotating parts and carry out maintenance during operation, and the maintenance should be lowered to the lowest position, and the suspended parts should be cushioned with skids.

3.Before the operation, it should be checked to confirm that everything is complete and intact, and there is no obstacle and other personnel within the range of movement of the boom and bucket, and the operation can be carried out after the horn is sounded.

4.In the cab of the excavator, the exposed transmission part must be installed with a protective cover.

5.In dragline or backhoe operation, the distance between the excavator track or tire and the edge of the operation shall not be less than.

6.The excavator is working on flat ground, and the brake track (or tire) should be braked and wedged.

7.The excavator is suitable for shoveling and digging in clay, gravel, peat and other soils. It is forbidden to use any part of the excavator to crush concrete blocks, frozen soil, etc.

8.No person shall stay within the swing radius of the bucket operation while digging. 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 shall not be collided, it is strictly forbidden to have people in the compartment, and the bucket is strictly prohibited from crossing 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.

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.

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. 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.

1. The harsh terrain environment of the mine. The site must be observed before the operation, the mine is located in a high-altitude area, there are many ramps and sharp curves, and the requirements for the operator are relatively high. In addition, the roads of small private mines are relatively narrow, and there are no stone roads, they are all dirt roads, and they cannot be walked in the rainy season.

The picture above is the scene of the open-pit mine project, where you need to pay special attention to safety when driving an excavator.

2. There are many hidden dangers of the excavator responsible for stripping operations. For the excavators responsible for stripping operations in the mine, they often work on the top of the mountain, which is quite dangerous. The mining team and the muck dumping team try not to be in the same line, otherwise it will be troublesome to roll down the stones.

In addition, there should not be too many excavators responsible for stripping when mining, otherwise the hidden danger is too great.

3. Mine excavation has great damage to the bucket. Excavators work in mines unlike in other places, such as digging hard rocks in mines, which can be very damaging to the bucket. The operators should operate the bucket correctly, adjust the position of the excavator according to the direction of the crack in the rock, so that the bucket can be shoveled in smoothly, and the force should not be too strong when digging, and the tooth root is easy to break.

4. Always obey the command of the safety officer. The mine safety officer is also indispensable, mining and stripping need to be coordinated by at least two safety officers, and need to be equipped with whistles and walkie-talkies, because the Ming Shiyin excavator driver can not observe the rear slope and the surrounding situation at any time, the safety officer needs to observe at the highest point, if no one directs the stone to fall is dangerous, which is also one of the mine safety hazards.

5. At the same time, mining should also be accompanied by slope repair, and the open-pit mine work has the characteristics of large workload and many potential safety hazards. While the excavator is mining, it also has to repair the slope by the way, because some slopes you can't repair well the first time, and it will be difficult to repair them later. The purpose of repairing the slope is to reduce the occurrence of rolling stones and landslides, which is even more demanding for the operator.

6. Remember not to listen to the sound during the loading operation. The excavator needs to pay attention to the operation on the slope at all times, remember not to turn on the stereo in the car, and do not listen to the song, the large mine excavator mining vibration, the loose mud and stones above may be shaken down. If the sound is too loud, the commander will not be able to hear the command or other problems, and it will be dangerous.

7. Pay attention to the stones that roll down after the blasting operation. Blasting operations are often carried out in the mine, special attention should be paid to safety after blasting, a full range of inspections should be carried out in advance, whether there is loose stones that will slip down, or due to the false cracks caused by blasting, the operator should pay attention to safety, ensure the safety of the excavator, self-unloading and then return to the work area.
