The operating conditions of automotive equipment, in particular, cargo semitrailers, on the roads of the former USSR are very significantly different from those in Western Europe, due to which the supporting structures experience significantly greater loads than those for which they are designed. It is also important that a significant part of the fleet of foreign-made semitrailers was purchased after the depletion of its resource on normal roads. Such conditions lead to the fact that welded and fastening joints of structural elements, and often the metal itself, are often destroyed.

increased dynamic loads when driving on uneven roads;
overloading often practiced by drivers (exceeding the rated carrying capacity);
active influence of aggressive media (salts, etc.), leading to accelerated corrosion;
a number of design features;
metal fatigue.

In addition to these natural causes, deformations and other kinds of damage occur as a result of road accidents, from which, unfortunately, no one is immune.

Most often, the negative impact of operating features leads to the following malfunctions:

breakage of the spring bracket (with mechanical suspension) or trailing arm (with pneumatic);
violation of the geometry of the rear gate portal;
detachment of attachment to the frame of the side struts;
cracks in the frame side members;
destruction of the connection of the traverses with the spar;
through corrosion of steel sides and gate leaves;
deformation of the underride guard.

Taking into account the specifics of the operation, quite often welding work on the repair of semi-trailers is carried out outside specialized technical centers - in small workshops, or at the enterprises' own repair base, often using homemade welding equipment.

For the suspension elements to work correctly, it is necessary not only to restore its attachment to the frame, but to achieve an exact correspondence to the previous position. For these purposes, experienced welders first fix the bracket with M16 bolts, thus ensuring accurate centering of the parts and the necessary pressing force of the bracket to the spar, and only then weld it with a continuous seam.

Often, in order to increase the reliability of the connection, additional reinforcing elements are installed from available materials - a corner or another profile.

Even the highest-quality welding is not able to ensure the reliability of the connection of these elements for a long time, due to which, after strengthening the side and rear struts, additional reinforcement is applied using homemade triangular metal parts - the so-called. "Kerchiefs", which are welded with straight sides to the spar and the strut on one or, more often, on both sides. This uncomplicated design greatly increases its rigidity and successfully withstands the inevitable effects of vibrations.

For the same purposes, "kerchiefs" are often strengthened by the racks even on new semitrailers.

An obvious mistake of inexperienced repairmen with such a malfunction is welding along the crack line. Such a solution is completely ineffective, since the weld is the zone of the highest stress concentration, and it breaks easily even under moderate enough loads.

The correct solution is to cut out a diamond-shaped window in place of the crack and insert a plate of the appropriate shape into it, welded with a continuous seam (the so-called "tambourine"); a change in the stress vector makes it possible to increase the strength of the structure many times over. To strengthen the spar in the area of its restoration, usually a plate, corner or channel is welded on top of the beam on "tacks".

Safety instructions

Mastering the requirements for safety in nature.

Pay attention to the ability and skills to use tools.

To instill in students to nature, mutual understanding with the environment.

Allocation of places, territory, tools and responsibilities.

According to the structure of the program, the program is a table in the form of an algorithm for the teacher's actions to study and instill generalized skills, laid down in slots, where generalized skills are located vertically, tools, equipment and devices, materials are located horizontally.

Reading the algorithms of the teacher's actions for working with the program is simple. The main thing is to understand: which of the skills is being studied for a certain period of time, how to find them when planning the process of action.

Every year, the knowledge of schoolchildren expands and deepens in the calculation of planning, production output, sales and summing up. Thus, economic knowledge is laid down gradually as the generalized skills are mastered and become generalized polytechnical knowledge and skills.

Each of the generalized groups of skills cannot be studied and consolidated by practice separately, they are combined, grouped or studied, formed in combination with other skills, depending on the tools, equipment, devices used and the nature of the types of productive labor performed. The defining beginning of the action is the material with its inherent properties. The form of education from this material prompts actions with it.

Thus, all types of generalized skills are studied, practiced, polished only during the manufacture of a specific product. The product can be very simple or very complex. The complexity of the product design, the many technical and technological solutions and determines the complexity or simplicity, the method or technique of manufacturing. It also suggests what complex of generalized, specific and professional skills the one who decides to do this should possess. In practical work, the student implements those skills that are needed and necessary when performing a technological operation and in general the entire technological process. The nature of this approach is gradual and is ensured as you master the techniques for performing the work.

In a labor training lesson, students gain knowledge in the process of performing direct manual labor and in mastering production technology. It starts with the teacher. He is the organizer of the activities of students to gain knowledge about the methods of acquiring skills, the form of education and changing the type and design of products, the technological process. It is important that schoolchildren, when using hand and power tools, machine tools, know and master them in the process of controlling them, working on them:

workmanship of parts;

what parts they consist of, their connections;

the possibility of replacing others;

safe driving conditions.

The possibility of such achievement of children's learning ability is provided by the student's creative attitude to labor, performing, productive activities in the skillful areas of the teacher, research, studying the approaches of students to their labor and educational activities. Here communication, the teacher's attitude is built on the basis of an explicit (explaining, explaining norms of behavior, cognitively directed) approach.

At the head of the general educational tasks for the development of the system of labor training of schoolchildren during the transition to market relations is the change in the structure of the content of labor training subjects and bringing them in line with the life orientation of graduates of incomplete and complete secondary schools.Now the life orientations of young people have changed in favor of personal interests, the educational policy of the state must take this into account. In this formulation of the issue of education, the orientation of the school curriculum towards satisfying personal interests (only not mercantile), aimed at strengthening the personal function of self-regulation, self-education of the child, also presupposes a change in the content of labor education in accordance with the changing life of society.

The content of the program should set the task of merging the processes of labor and learning within one subject. The unifying functions of these processes are generalized skills that functionally integrate the vision of the mode of action with the mental image of the flow of the technological process and control the mental activity of children during execution, i.e. in the implementation of this task. Thus, the subject of labor training is designed to increase the intellect of the child, promote the development of the mental abilities inherent in nature more effectively, more objectively, more effectively, since the child sees the result of his successes with his eyes, feels with his hands, takes a soul or worries and worries that suddenly his work is not will be confirmed by objective data. Therefore, he searches, investigates in order to find the right action.

Our choice of the object of training coincides with this scheme. In our choice, we put forward in the first place generalized skills as functional features of any technique, technology and proposed the task of mastering these functions. The program posed for the children the problem of mastering generalized skills in the logic of the development of activity as a special tool for the necessary and sufficient provision of opportunities to achieve the goal. The child's thinking should be directed in such a way that the means provided to him decide how best to master the skills and use them to solve other problems.

The preserved traditional methods and techniques are further developed with the introduction of the "Fishing Tackle" circle, which raises the educational process for the labor training of schoolchildren to a higher level in the light of modern requirements.

Thus, for any technique, tool, machine, and above all, the question is posed: cuts, saws, planes, chisels, embroiders, sews, beats. - that is, the definition of the functional purpose of the object through which the generalized polytechnic skill is processed. What corresponds to this or that object? After that, the exploitation of technology, the tool becomes the mechanism through which the mastery of functions - generalized skills - is formed, perfected. Learning in this way shifts back the study of the structure of the technique itself. Its management, as the beginning of the functioning of an object, must be shown reproductively in compliance with safety measures and taking into account the age of the children. Here it is important to know not the details of the object, but to be able to control its functions. Due to such objective reasons, proven and practically confirmed theories of polytechnic knowledge, the principle of the object study scheme was abandoned in the curriculum for the subject of study: device - principle of action - operation - functions.

Providing children with the opportunity to practically solve the problems of labor education will make the subject accessible, make the impossible possible, and far from "goals" - the subject of action. The process of cognition begins with the properties of the material used, the features of the functions of the tools used, etc. To change and obtain a new objective form through action, not simple, but creative. In this regard, it is appropriate to quote the statement of M.N. Skatkin, who, analyzing the function as a teaching tool, writes: “The function has mobility. A function is a specific activity, and an activity is an alternation of realized skills.Function mobility is nothing more than the transfer of skills from one situation to another. "

here is my branch where I repaired the frame.

my car is running on a daily basis now.
everything works well there are no comments on the repair of the frame.
It's a good idea to wrap the old frame with a new one that fits.
you still need to start such a repair with sandblasting
god help.

Fig-behold, what frame should you pay attention to? Which one is closer to “us” or which is all in rhombuses? How does Kyzya miss such a thing?

Yes, about ZIL, I'm also interested?

the one that is closer, I sold them a half-cut, they will splicate it with their tail (by the way, it is from zil).

and here are the last photos of my zilka

[QUOTE = Dzenz; 1151760895] The frame broke on both sides. Broken at the attachment point of the rear ladders. I was looking for something similar on the forum did not find it.
Looking for advice on how BEST to brew?
Can someone help with a material?
I would be grateful for any useful advice.

Low loader trawls are widely used in modern cargo transportation, having a number of advantages over their standard counterparts. The main feature of the trailer lies in the low location of the platform, which makes it possible to transport goods under power transmission towers, bridges and other obstacles. Unfortunately, such a design feature also determines the most vulnerable spots, which is why the repair of low-loader trawls is periodically required. With the highest level of efficiency and at a low price, it will be carried out by the specialists of the "Trakservice Perm" company!

These trailers are quite complex structures, and therefore, when working with them, it is necessary to solve a set of tasks:

It should be noted that the repair process may involve not just the return of the functions lost by the trailer or the restoration of its working capacity. The specialists of our company are ready to take on the improvement of structures. So, welding of special stops is in high demand, making it possible to firmly fix flashing beacons that increase the visibility of the vehicle on the road, markings and other details.

Repair of low loader trawls is carried out in full compliance with the following rules:

Promptness... The low loader trawl is a working tool that generates income, and therefore delay promises financial losses for the customer. We cannot afford that.
Maximum quality... The professionalism of the craftsmen, coupled with the use of modern equipment, guarantees an ideal result in the most difficult cases.
Only reliable spare parts... Spare parts, consumables and materials are fully consistent with the originals, which helps to completely restore the functionality lost by the transport.

Our masters are always glad to new customers, managers are ready to advise on all questions of interest regarding the repair of low loader trawls, call!

FLATS, TRAVELS, TENTED TRUCKS, TANKS, DUMP TRUCKS

Needless to say, everything breaks down here. Moreover, even if you purchase a thing, product or mechanism of very good quality, there is no guarantee that all this will not fail during use.

So the trawl owners will sooner or later face the need to repair this type of equipment. Moreover, here the principle will be the same - no matter how high-quality and good your trawl is, no matter what manufacturer it is (Russian or foreign), during operation you will not be insured at all from breakdowns.

Therefore, such a service as the repair of trawls is becoming more and more in demand today. And if we take into account the fact that trawls are now used for transportation everywhere - for cargo transportation, for construction companies, for industrial organizations - then the relevance of repair work is increasing.

Let's take one situation as an example. As a rule, such equipment as trawls is purchased from the company in quantity, well, a maximum of 1-2 copies. So, you have purchased a low-loader trawl for transporting goods. And in the process of work, you have it out of order. And it turns out that everything has stopped with you ... And urgent repairs will be needed here. How to be here? Contact the organization that deals with these types of work.

At the same time, if you need to repair a low-loader trawl, when choosing a company to which you can entrust this service, be sure to pay attention to:

- Experience of the repair team. Do not forget that trawls are quite complex devices. Therefore, the specialists who will work with them must have certain skills and experience. The ideal option here is to contact companies that are engaged in both the production and repair of low loader trawls, they certainly know how it is here and what works!

- Availability of the appropriate tool. Here, in principle, everything is also clear. If there is no necessary tool, then the work cannot be carried out at the highest level.

- Efficiency and quality of work. A very important point, especially in cases where you have only one trawl for work, and in order not to get out of the already established schedules, you will need to carry out repairs in a short time.

Let's also note the following point. Often, trawl owners and companies that lease this equipment know that they have some technical problems with a semitrailer. But they are not taking any measures. But all this can lead to the most dire consequences. How? Just imagine a tractor with a faulty trawl. This is a direct threat to the health of the driver and other road users. This is a source of danger on the road!

Now, as for the works themselves, they can include the following criteria:

- replacement of consumables.

Naturally, this list is approximate and incomplete and implies the initial diagnostics of the product in order to make a more accurate and competent "diagnosis".

Cars we work with

Low loaders or platforms ("low loaders") - a special type of trailed equipment with a low-loader platform, used for the transportation of bulky and heavy loads weighing from 20 to several hundred tons.

Any cargo equipment does not last forever and sometimes fails. Our company is ready to offer individual service and repair of trawls ("low loaders") with a wide range of original spare parts.

Repairing a trawl can involve restoring a wide variety of parts. One of the most difficult and demanding types of work is frame repair.

The frame is the structural basis of the semitrailer, which performs the load-bearing function. Therefore, during operation, it takes on the maximum loads. If it is damaged, the operation of the trawl is virtually impossible. In these cases, repair or replacement of the semi-trailer frame is required.

Frame damage and defects are of different nature. They can arise as a result of natural wear and tear, as a result of an accident, when the semitrailer is overloaded or when the conditions for its operation are violated (for example, when the load is unevenly distributed on the platform or when operating a trawl with a faulty chassis, etc.).

Depending on the nature, the following types of damage and frame defects are distinguished:

violation of the geometry of the frame;
bends and cracks;
frame fractures;
variance in wall thickness.

High quality and maintainability of modern trawls allows for effective frame restoration even in case of serious defects. The exceptions are cases of plastic deformation with a loss of rigidity of the main elements, as well as cases of complete violation of its structural integrity, when a complete replacement is required.

Our company performs qualified overhaul of the semi-trailer frame in case of defects of any nature. For this purpose, we have at our disposal modern equipment, and our specialists are highly qualified. Modern equipment used in Tverstroymash makes it possible to provide a comprehensive restoration of geometry and elimination of deformations. To restore the integrity of the frame elements, advanced welding technologies are used. All this makes it possible to ensure effective repair of the semitrailer frame, even with the most complex damage. The quality of service for each client is controlled by a personal manager.

Our service centers operate not only in Tver, but also in other cities of the country, such as Penza, Perm, Nizhny Novgorod, Tyumen and Krasnodar.

We repair trawls of our own production. STO Tverstroymash also repairs and refurbishes semi-trailers from other leading manufacturers, including KOGEL, SCHMITZ, Goldhofer, KRONE, Nooteboom, Faymonville, Witzco Chelenger, Wielton, Fruehauf, ChMZAP, TONAR, NEFAZ.

Knitting fishing nets

Page: 1/4
Fishing nets of various modifications have long been considered the most effective fishing gear. And in fact, if one fish is caught with a line, then nets. Although we know of one old man who, throwing a seine into the sea, also pulled out only one fish. True, that fish was not easy. Apparently, the old man still knew some secret of fishing. However, let us turn to the classics, since such an appeal can be very instructive.

Running a little ahead, I will say that fishing net knitting video located on the last page of this article. However, for a better understanding of the whole process, it is better to read everything in order.

Let us break off the quotation at this point, since further lies outside the topic of this article, and pay attention to the following. “The old woman was spinning her yarn. ”- writes Alexander Sergeevich. Apparently, it is no coincidence that this line is adjacent to the line where the net appears.

If an old man for more than thirty years fished and did not live well, then, apparently, his fishing tackle from time to time in need of repair, and he used to repair his fishing gear with the yarn that the old woman gave him. And this is already essential for the topic of our article, since we are very interested in the materials used for the manufacture of fishing nets. We will return to the topic of materials a little later, but we will naturally talk about it in the light of the latest achievements of science and technology (after all, we can't use old woman's yarn either).

And one moment. Apparently, that old man used the so-called with a seine, which is thrown from the shore, and then pulled back.And we are also very interested in the questions of varieties of net fishing gear. It is with them that we will begin a serious conversation.

There are seines of other types (that is, not only seine nets). However, there is not only a seine. Fishing nets are varied not only in purpose, shape, but also in size. The latter, in essence, determines the difference between industrial and amateur fishing nets - the scales are different. Although the principle remains unchanged: amateur fishing with nets is an industrial one in miniature.

So the main net fishing gear quite varied.

Trawls. Trawls vary greatly in size and design. But they also have common features. The bag of any trawl has the shape of a funnel - the entrance to it is open, but there is no exit from it. The trawl is towed by a pair of cables called warps. Depending on the depth of immersion of trawls, they can be bottom, deep and mid-water. A set of floats and a pair of wooden spacers attached to the warps keep the net entrance always open. This system is similar in principle to a kite.

Purse seines. The purse seine has long side net walls, like an old purse. These walls hang vertically, their upper part is supported by floats, and the lower one is pulled back by weights. The bottom of the seine can be pulled together and become a fish trap. The caught fish accumulate in a relatively small bottom part of the seine, which is lifted aboard the vessel by hoisting ropes attached to it.
