1. first of all, why do employers sometimes look for loaders to park their floors?
The strength of the loader is the shovel, and some time, such as loading and unloading to fill the material back... But in these working conditions, often there will be some level ground needs. Limited site in the city is not suitable for large-scale grader operation, and some are not leveling the site to do much work, hiring large equipment can not do. So the loader is the protagonist of leveling the ground at this time, of course, sometimes leveling with excavators, but this situation is very rare!
2. what should a driver know before levelling?
As a driver, it is not only to understand the performance and basic maintenance of the vehicle, but also to understand the nature of the operating material (clay stone and so on), which depends on the area.
For example, when I am on the flat floor, I usually have these kinds of materials.
"Primitive soil", generally this kind of soil is the soil in the basement of a building in the city. Under normal circumstances, the original ground, from the top to bottom, usually has about one meter of black soil, and then the yellow sand soil with yellow gravel or breccia, with the yellow sand soil with the indeterminate loess and the sand between one and three meters. Stone!
"Mountain pepestone", the south does not know how to call, but the north is so called, the use of this material is generally the specific requirements of the construction side, for example, a site needs to repair roads or need to build a factory, but the original ground low lying, or the ground hardness is not enough, this time will be specially required to use this mountain skin. Stone backfill! This material has good water separation performance and small subsidence range. Generally, it has a diameter of not more than ten centimeters of stone and mixed with mountain soil. This material material is very good, that is, repair highway construction side will use this material back fill the roadbed. The only thing to guard against when working with this material is the sharp edges and corners of the material. Be careful not to scratch the tire.
"Mao Sha", this is what we call this, I explain to you that "Mao Sha" is the natural formation of the original sand in the river without any cleaning, called Mao Sha.
This kind of material is generally used in what circumstances, for example, a site has passed the "original soil" or the backfill of "mountain pestle" to form a horizontal plane and after it has been compacted, it needs to be hardened with concrete. At this time, the construction party will harden again after a layer of sand, and the general thickness is required to be 10. The technology of loader drivers will be shown in the -20 cm distance.
"Building rubbish", this kind of material do not need me to say what everybody knows is what, generally it is the building of the city in the latter part of the building has been completed to be completed in the periphery of the building, for example, the construction of the underground garage, this time the ground should be built on the ground. "The original soil" was cleaned out, and the material was generally not allowed to backfill, but some personal owners or the builders had to do it in order to reduce the budget.
These kinds of materials are all my ordinary homework will meet, the nature of these kinds of materials must be understood before the construction, the general old driver this can be ignored!
3. understand the construction requirements and expected results before leveling the site.
Don't rush to work at a certain venue, communicate with the staff of the site. Asked what to do after leveling the site, the site is required to achieve a horizontal effect or to achieve a certain direction of drainage effect.
4. know the performance of your own loader before leveling the site.
There are two different working devices for the loader, which are divided into single rocker arm and double rocker arm. The loaders of the two different rocker structures are different. See some of the possible friends here, what are the buckets that can be said, not all the same? The specific points of the frame are different, the device on the bottom of the bucket will be different, and the angle of the bucket will also be different. For example, I like the double rocker bucket, for example, the double rocker arm series of the double rocker arm series of Shanxi workers and double rocker arm series, which is flat at the bottom of the bucket, and has a large contact area with the ground, and the error of the ground level is small.
And the single rocker frame of the bucket is different, the bottom of this bucket is not flat, the front of the arm and the shovel contact is two similar to the things, on behalf of each type of car manufacturers I feel the worst is the best use of the Liugong 50C shovel!
There is also a different degree of shovel wear for each vehicle. The angle of bucket shovel is different.
5. before leveling the site, control the material quality according to the different elevation and do not repeat the operation.
6. adjust your mind before you do homework. Remember not to be impatient. As the saying goes, "be too hasty to eat hot tofu!"
7. get on the train must have the feeling, must achieve the human vehicle unification. Our loader belongs to the shovel excavator. When the loader works, the driver can't see the work of the shovel. At this time, as a driver, we have to do the deep and shallow heart. Every subtle movement will greatly affect the construction progress and the quality of the construction. This is the feeling I say!
8. be good at using the arm and the bucket for compound action. When the loader is working, the big arm and the bucket are like fish and water, and many new drivers are not good or do not use the big arm and the shovel at all to do some coherent complex movements. This leads to low efficiency or no smooth leveling.
Some drivers have come to a certain site and have a good state of mind when leveling the site, but the work method is not right, and the results are not good. The construction workers on the site are anxious to have body language, the driver is more impatient, the work is a fog water, the smooth effect is not good, there are also from the application. Worker
The invisible pressure, the mentality began to be bad. In the end, the work could not be done, and the equipment was basically abandoned by the constructors.
The work is not done, and the money can not be made at the moment. It also leads to the fact that it is impossible to receive the work of the site again.
9. flat ground for speed requirements!
When the floor is leveled, the speed of the work is reduced. The speed is often too fast.
10. flat ground for safety precautions!
One question: before leveling the site, be sure to ask the builder if there is a cable pipe, cable, and septic pipe well, not to break cable cable or to avoid falling into some engineering septic tanks.
Two see: before the homework, see if there are walls, building materials, building equipment...
Three observation: before doing the homework, observe where there is a safety hazard in the site, pay more attention to the movement of the personnel, especially in the countryside or in the rural construction, when the building garbage is backfilled, there will be some steel pipe scaffolding buckles in the material. Observers, work is a minor matter, safety is a major matter, when necessary, you can communicate with the builder, let the site staff help alert!
Well, there are so many, in fact, these considerations are very simple, as long as you keep in mind what I said, work will be twice the result with half the effort.
