How to modify the excavator to extend the boom? How to cooperate with the big arm and small arm of t

When the standard arm of the old excavator is modified from the extended arm of the excavator, the first thing to measure is the performance of the excavator, such as whether the hydraulic output reaches a certain pressure; Can the traveling mechanism, turntable structure, etc. carry the excavator extension arm, and how long can the extension arm bear?

The service life of the old excavator and the length of construction work have a direct impact on the performance of the excavator itself, such as no digging force, weak lifting arm, slow walking, etc. The excavator has these reasons, and it is difficult to exert the efficiency of the extended arm excavator after being modified to an extended boom. Before the modification, it is best to enter the quality inspection of the excavator, and through the quality inspection, you can have a clearer understanding of the performance of your own excavator, so as to choose a more suitable extension arm for modification!

Clarify the excavator extended arm operation requirements and working conditions.

The length of the excavator extension arm is directly related to the quality and output pressure of the excavator itself. When we select the excavator extension arm, we should balance the length of the excavator extension arm according to the excavator operating environment, operation requirements, its own quality, the capacity of the bucket and other auxiliary devices; The two-stage excavator extension arm often involves three main parameters in the construction operation: excavation height, excavation depth and working radius; The three-stage demolition machine extension arm often involves three main parameters: lifting height, safe working height and operating radius. Only a comprehensive set of factors can determine how long the excavator extension arm can be equipped with this model.

The corresponding model modified excavator extended arm configuration length reference parameters.

The excavator extension arm commonly used in the industry is that the large and small arms are lengthened at the same time, and the turning radius is relatively large when working. Such as meters, 16 meters, 18 meters, 20 meters, 22 meters, 24 meters, 25 meters, 26 meters, etc. In fact, at 10-30 meters or even longer, the length of the extended arm modification can be arbitrarily chosen.

The specific choice is based on your construction conditions.

1: Clean up rivers or fish ponds.

The use of excavator extension arm can often be used in the work of cleaning rivers or fish ponds, which are deep working sites, so to dig need an excavator with an extended arm to be sufficient.

2: Subway excavation.

In the construction of subway projects, all tracks or foundations also need to use excavator extension arms to carry out, but also because of the high depth of excavation and wide slots, it is necessary to extend the excavator extension arm to carry out smoothly.

3: Water conservancy and hydropower projects.

In the construction of water conservancy and hydropower projects, it is also a major project that often uses excavator extension arms, which can be excavated according to the required depth. In water conservancy and hydropower projects, the excavator extension arm is called the king of dredging in the project, which shows that its excavation ability level is very good, and the dredging capacity is stronger. And in the use of water conservancy projects, the arm length can also be lengthened and modified according to the specific depth.

4: Construction handling use.

In order to quickly carry out high-rise transportation of soil sand or concrete at major construction sites, it is also necessary to use excavator extension arms to help with transportation. This not only reduces the burden of manual handling, but also improves safety.

To sum up, the excavator extension arm plays a pivotal role in important engineering operations, and it can be applied to a variety of different deep excavation work, so it is deeply loved by construction personnel. Hopefully.

One end of the big arm main body of the excavator is a big arm fork, the small arm is connected at the big arm fork of the big arm, the big arm and the small arm are hollow body structure, the big arm and the small arm hollow body structure are filled with filler inside, the big arm and the small arm hollow body structure are not provided with the inlet and outlet of the filler, and the lever principle is mainly used to maximize the excavation force of the equipment output.

By changing the size and structure of the big arm and the small arm of the excavator, the excavation force point of the big arm and the small arm is closer to the center of the whole machine, so that the whole machine is balanced and stable while the output force is the largest, and the inlet and outlet holes are not designed on the big arm, so as to ensure the safety of the big arm in the work, and the weight of the filler of the big arm is designed with the weight of the big arm required by the hardest rock of the excavated conventional rock and soil, so that the big arm can be comprehensively utilized in various working environments.

When digging the soil, the cooperation is not too particular, the requirements are relatively high in the leveling, the lower arm can be pulled back and pushed forward when the lower arm sags to 90 degrees, or the small arm is stretched out and the ground angle of 45 degrees and then to the small arm, lift the big arm, reduce the big arm when the vertical position is raised, the small arm continues to be at the original speed, you practice to see.

I don't understand what you mean, is it referring to the action of the big arm and the small arm when driving the excavator?

1. A working cycle of the excavator is excavation-slewing lifting-unloading-slewing lower boom, so the cooperation between the big arm and the small arm must be two situations.

2. The first situation: excavation operation. Look at individual work habits. Many people rely on stick digging power, while others rely on boom lifting. I recommend that after the bucket is dug to a certain position, the boom handle is pulled to the end, and the matching method of the stick handle is constantly moved;

3. Rotary unloading. Flip the stick and flip the bucket. It is recommended that the bucket travel is greater than the stick stroke.

I don't know if the above personal opinion is helpful to you.

The extended arm is divided into: the two-stage excavator extension arm and the three-section excavator extension arm, the two-stage excavator extension arm can be lengthened to (13-26) meters, and the two-stage excavator extension arm is mainly suitable for earthwork foundation and deep trench and long-distance dredging mud excavation operations; The three-section excavator extension arm can be lengthened to (16-32) meters, and the three-section excavator extension arm is mainly suitable for the dismantling of high-rise buildings and other projects.

The main supporting weight and configuration of the excavator extended arm and the extended arm are:

The 16-tonnage excavator custom-made extended arm and extended arm can be lengthened to 13 meters, and its configuration is: a bucket, a bucket cylinder, six pins, four high-pressure hoses, three butter pipes, a set of connecting rod assemblies, and a group of high-pressure hoses with a long arm (m) and an extended arm (m) with a counterweight of one to three tons;

Well, it's best to ask the manufacturer of this machine, if he also makes it.

Since you want to choose the excavator extension arm configuration, then it depends on what kind of excavator extension arm you have, whether it belongs to the two-stage, three-stage or small excavator? These styles vary and require different configurations. For example, 10 to 16 tons of excavator custom lengthened or lengthened arm, generally can be lengthened to 13 meters, belongs to the configuration of this extended arm for a bucket, bucket cylinder, six pins, four high-pressure hoses, three butter pipes, a set of connecting rod assembly, has been equipped with a high-pressure hose to lengthen the arm (m) and the extended arm (m) each group, counterweight one to three tons.

If it is a 20-22 tonnage excavator custom extended arm, extended arm, we can lengthen the point, add to the meter line, its configuration for a bucket, bucket cylinder, six pins, four high-pressure hoses, three butter pipes, a set of connecting rod assembly, has been equipped with a high-pressure hose to grow the arm (m) and the extended arm (m) each group, counterweight one to three tons.

Excavator extension arm is a kind of working equipment, which can increase the working radius and depth of the excavator, and is suitable for occasions that require deep excavation or long-distance excavation. Here are some suggestions for excavator extension arms:

1.Choose the extension arm model according to the actual needs: different types of extension arms are suitable for different occasions and working conditions, and it is recommended to choose the appropriate model according to the actual needs.

The same is true for the excavator extension boom industry. Shopping malls are like battlefields, and where there are people, there will be rivers and lakes. There are all kinds of competition in the marketing of excavator extension arms, including external competition and internal competition.

External competition has been elaborated many times in other articles before, and this time the main point is to analyze the internal competition in the marketing of excavator extension arms.

The customers of the excavator extension arm industry have different levels such as machine manufacturers, distributors and end customers, and the end customers can be divided into leasing companies and self-employed, and the preparation form, region, nationality, personality and other characteristics of the customers are very different, so the regular excavator extension arm manufacturers will have a number of marketing personnel to dock customers. "Eggs can't be put in the same basket", from the perspective of the company's safety, advocating "a hundred flowers blooming, a hundred schools of thought contending", and hiring a number of marketing personnel to engage in the marketing of the excavator extension arm is particularly important. Since the company's assessment of marketing personnel is assessed separately, the internal competition in the marketing of excavator extension arm objectively exists.

Since the internal competition in the marketing of the company's excavator extension arm objectively exists, what are the benefits for the company? First, through internal competition, the individual ability of marketers and the marketing level of the whole company can be improved, just like the national table tennis team and badminton team often hold internal competitions; Second, it is conducive to enhancing the external competitiveness of the whole company, "there is no disrespectful individual, only a flawless team", even if a person has strong ability, it is vulnerable to a team. The third is through internal competition to cultivate and discover the company's need for a variety of talents, the competition of enterprises in the final analysis is the competition of talents, who has more talents, who will be invincible in the fierce market competition.

The internal competition in the marketing of the excavator extension arm is objective and beneficial to the company, so the company should actively encourage fair and just internal competition and create a fair and just internal competition environment. Of course, we do not promote unfair internal competition by unscrupulous means, low-price competition, or other unfair means. Unfair internal competition can only be avoided by formulating and improving relevant rules and regulations and strengthening self-cultivation by marketing personnel.

A lone show is not spring, a hundred flowers bloom in spring", China's excavator and bright spine long arm industry must pay attention to and standardize the internal competition in marketing, strengthen the country, go out of our country, and achieve a "win-win" situation for the country, enterprises and individuals
