Inspecția zilnică este o legătură importantă pentru a se asigura că excavatorul hidraulic poate menține o funcționare de înaltă eficiență pentru o perioadă lungă de timp. Făcând o treabă bună în inspecția zilnică se pot reduce în mod eficient costurile de întreținere.

1. Atunci când excavatorul se oprește, verificați cu atenție dacă șuruburile de ancorare și șuruburile plăcuțelor de rulmenți sunt slăbite, angrenajul și lubrifierea fiecărei părți, precum și rulmenții, dispozitivele de putere, sistemele de control, frânele, cutiile de viteze, saboții de șenile și piesele de bază. Dacă există uzură și deteriorări anormale la diverse piese, cum ar fi cablurile, cablurile metalice și dinții cupei;

2. În timpul funcționării, acordați atenție funcționării fiecărui motor, transmisie mecanică, sistem de frânare, sistem de control, ventilator de răcire, iluminare și semnalizare etc., precum și detectarea și rezolvarea la timp a diferitelor probleme în timpul inspecției;

3. For newly installed excavators, all parts must be filled with oil before trial operation, and the lubrication conditions must be checked in shifts within the first week of work; for excavators that have been out of service for a long time, the original Squeeze out all the old dry oil. Good lubrication can reduce mechanical wear and failure during operation. Lubrication work must be carried out in strict accordance with the time limit, oil quantity and type of lubricating oil specified in the excavator manual;

4. Elementul de filtrare are rolul de a filtra impuritățile din circuitul de ulei sau din circuitul de gaz, împiedicându-le să invadeze sistemul și să provoace defecțiuni; toate tipurile de elemente de filtrare trebuie înlocuite în mod regulat în conformitate cu cerințele din (manualul de operare și întreținere); atunci când înlocuiți elementul de filtrare, verificați dacă există atașamente metalice Pe vechiul element de filtrare, dacă există particule metalice, diagnosticați și luați măsuri de îmbunătățire la timp; utilizați un element de filtrare pur care să îndeplinească cerințele mașinii. Elementele de filtrare false și inferioare au o capacitate de filtrare slabă, iar dacă calitatea materialului de pe suprafața stratului de filtrare nu îndeplinește cerințele, aceasta va afecta grav utilizarea normală a mașinii.

5. Întreținerea zilnică; verificați, curățați sau înlocuiți filtrul de aer; curățați interiorul sistemului de răcire; verificați și strângeți șuruburile saboților de șenile; verificați și reglați anti-tensionarea șenilei; verificați încălzitorul de admisie; înlocuiți dinții cupei; reglați jocul cupei; verificați nivelul lichidului de spălare a geamurilor față; verificați și reglați aerul condiționat; curățați podeaua cabinei; înlocuiți elementul filtrului de spargere (opțional). Când curățați interiorul sistemului de răcire, după ce motorul este complet răcit, slăbiți încet capacul de admisie a apei pentru a elibera presiunea internă a rezervorului de apă, apoi eliberați apa; nu curățați atunci când motorul este în funcțiune, ventilatorul rotativ de mare viteză va provoca un pericol; când curățați sau înlocuiți sistemul de răcire În caz de lichid, mașina trebuie parcată pe un teren plan.

6. Elemente de întreținere la fiecare 250H. Verificați nivelul uleiului din cutia de transmisie finală (adăugați ulei pentru angrenaje); verificați electrolitul bateriei; înlocuiți uleiul din cuva de ulei a motorului, înlocuiți elementul de filtrare a motorului; lubrifiați inelul de rotire (2 locuri); verificați tensiunea curelei ventilatorului și verificați Reglați tensiunea curelei compresorului aparatului de aer condiționat.

How to find a mini excavator with reliable performance and low price in the market?

If you are in the construction industry, then you absolutely need a mini excavator. From digging and trenching to demolishing and cleaning debris – there’s so much going on in these compact machines. For any contractor or construction company, owning a mini excavator can significantly reduce costs from manpower-intensive tasks.

But while paying off well in the long run, most mini excavators come with a high upfront cost when you buy them. Does that mean you should give up on the idea of buying one? of course not! What you need to do is find a cheaper model that fits your budget without compromising on performance.

So how do you find the best cheap mini excavator that does the job right? This can only be achieved through in-depth research and knowledge of the market. To do this, you must understand the factors that determine the cost and reliability of a particular model. Let’s explore these two factors together!

What are the factors that affect the price of small excavators?

Brand Awareness

If you’ve done your research, you can have a pretty good guess at how much your mini excavator will cost, just by knowing the brand of it. Like all other things, brand awareness is one of the key factors in determining how much something will cost. Just like you would expect a Gucci bag to be much more expensive than the bag you buy at target, a mini digger from a major brand will be much more expensive than a brand you’ve never heard of.

Key Parts

The key components of a mini excavator include the engine and hydraulic system. These factors not only directly affect the performance of the mini excavator, but the quality of these components also determines the cost. If all you need is an average mini excavator that can do some digging, you can probably get one for cheap. But if you’re looking for some quality trenching, you’re going to have to bring in a cannon with a more powerful engine and hydraulics. Of course, this upgrade comes at a price.

Key Hydraulic Components

Additional Functions

The cheapest mini excavators feature a lot, but you may have other requirements that they can’t meet. If a standard built mini excavator can’t do the job you want done, you’ll want to look at a mini excavator with additional features. Side swing arms, zero tail swing, extended arms or extended undercarriage – each additional accessory makes the machine more expensive.

Maintenance And Repair

Last but not least, the maintenance and repair frequency and needs of a mini excavator also largely determine its final cost. A machine that requires little maintenance between uses will cost more in the market, but will end up costing less in the long run. Conversely, mini excavators that require frequent maintenance have lower upfront costs.

What determines the reliability of a mini excavator?

Source

While it is true that simply using a big brand name on a piece of equipment can significantly increase its price, we must also admit that the quality of a machine sourced from big brand components is much higher than that of an unknown brand. This is because big brands need to maintain their reputation in the market and cannot risk producing substandard equipment. So, if you want to buy with ease, it is always a safer route to go for a reputed brand.

Sourcing routes like Kubota and Yanmar are known for their powerful engines. Likewise, hydraulic components from Shimadzu, Hyde, Doosan and Eaton remain unmatched.

Standardized Production

A brand of small excavator, if it is large enough to ensure the standardized production and quality inspection of its equipment, automatically becomes reliable. The company has done all the necessary tests for you, and you don’t have to worry that there might be something wrong with the product you purchased. There are always exchange and return options for equipment in rare cases.

Mass Production Of Small Excavators

Reasonable Industrial Design

If your mini excavator has multiple extras but lacks a well-designed core, you might as well throw it out now. For a mini excavator to be reliable, it needs to be built on a sound industrial design. The structure of the device itself is a very important factor in determining its robustness and reliability.

Emission standard

The emission standard of your compact excavator does not only affect the environment, but also the performance and robustness of your machine. Confused? Let us explain.

Mini excavators that are Tier 4 certified (EPA 4) are designed to burn fuel cleaner and reduce air emissions. This minimizes the dense byproducts of combustion from settling in the bottom of the fuel tank during cold weather conditions and causing potential problems in the engine. Hence, your excavator needs less frequent cleaning and maintenance in between uses to function properly.

Trench digging can be said to be one of the basic operations of a mini excavator. It seems simple but actually has a high technical content. In the process of digging trenches, many novices often have problems such as not being straight, digging off-track, and the bottom of the trench is wide or narrow. So what are the operating skills of trench digging? Take a look at the basic operation of trenching shared by “Rippa Group”.

The trench must be dug straight

The most basic principle of trenching is to follow the principle of straight digging. Generally, the route of the lime trench is drawn on the construction site. The center line of the chassis of the mini excavator is aligned with the lime line, and the teeth in the middle of the bucket correspond to the lime line, so that it is not easy to dig away. Biased.

If there is no lime line, you can use the track to press out a connecting line first, and the track traces left can play the role of the lime line. Bucket motion can then be adjusted to the track print left by backing up.

Ditch the surface first

When formally excavating, first take the surface layer, and then remove the lower layer. Never dig to the bottom at one time, especially the excavation of deep trenches is especially important; when digging a trench larger than the width of the bucket, first dig both sides, and then Dig in the middle.

Maintain the flatness of the slope

Many novices are not good at digging ditches, mainly because they have not done the principle of neatness, and the detailed operation needs to be further improved. From the beginning of opening the V-shaped ditch to the end, the slope must maintain the same slope. Of course, the soil quality and the depth of the ditch are different, and the slope needs to be adjusted accordingly.

The two lines on the graph are straight, which is the premise of keeping the slope of the ditch flat. When digging a ditch, the operator must pay attention to the loose soil on the side of the ditch to prevent the soil from falling, and clean it up with a bucket in time.

Ditch Bottom Control.

The control of the bottom of the ditch is very important. At this time, it is necessary to use the skills of throwing squares and leveling. If the trench is to install water pipes for drainage, a certain slope at the bottom is required; if it is a house foundation pit, the bottom is required to be level.

In fact, many operators are not sure about the height of the bottom of the ditch. When there are surveyors, they can ask the construction workers to measure with instruments and measure while digging. If you don’t have any, you can find some references, and you should get out of the car to observe more.

Three ways to dig a trench.

The basic operation skills of trenching have been briefly introduced above, and finally three trenching methods are introduced for you:

(1) Ride-digging type: mainly in open areas, the excavator is parked in the middle of the ditch to be excavated, and the bucket is dug between the two crawlers.

(2) Side-by-side type: It refers to the relatively narrow area of the site, like a clear water channel, the bucket only digs along one side of the track line (here requires the use of slope skills).

(3) Face-to-face type: mainly for the excavation of road culverts, which means that the excavator is parked at a 90-degree angle to the side of the ditch (it should be noted that when the ditch is relatively deep, the bucket cylinder may touch the ditch side)

In short, the operator needs to pay special attention to the straightness of digging, the flatness of the slope, the control of the bottom of the ditch, etc. in the process of digging the ditch. It is not difficult to choose the appropriate ditching method.

One of the most valuables pieces of equipment on a construction site is an excavator, which has helped countless projects work more efficiently and effectively. But what is an excavator used for, and why is it so essential for many heavy equipment jobs?

To understand what an excavator is used for, it is helpful to look at the components. An excavator contains what is called a house, undercarriage, boom, stick, and bucket. These components feature the motors and gears to move the equipment, lift the bucket, and a spot for someone to sit and be in control of the machinery.

The main uses for an excavator are digging trenches, holes, and foundations, providing the power to do these tasks much more easily and effectively than any other piece of heavy equipment on the market. Companies across many industries may be looking at excavators for sale in China thanks to the wide range of industries they are used for, including forestry, mining, and all types of construction. In addition to digging, excavators are commonly used for projects such as demolition, dredging rivers, material handling, or just simply heavy lifting of objects.

With such a wide range of uses, it makes sense that there are different types of excavators to help find exactly the right one needed for the job at hand. One example is a tracked and wheel excavator, which is perfect when the job calls for things such as digging, material handling, brush cutting, demolition, open-pit mining, forestry work, and much more.

There are also mini excavators, which are smaller and lightweight, which makes them easier to transport quickly and efficiently to various construction sites. These types of compact excavators are ideal for trenching, as well as a wide range of utility work. In some cases, with the advances we have seen in hydraulic systems, these smaller excavators can even outperform larger machines, pulling their weight in a way that many people looking at heavy equipment for sale.

Cum să vă conduceți excavatorul în siguranță?

No matter what job you do, your health and life safety are the most important. “Excavators” in the engineering field should also have this awareness to protect themselves and their excavators at work. Speaking of safety knowledge related to driving an excavator, there are many. Here I will share with you the precautions before work.

First, pay attention to the state of the operator. As the core of the work, the excavator operator will make the excavator, a huge machine, perform various actions in the following work, and their status is closely related to the safety of the work. Therefore, if the operator is found to be fatigued, sick, mentally disturbed, or under the influence of drugs and alcohol, it is necessary to consider replacing the operator or suspending the operation, otherwise the operator is likely to make the excavator make improper actions due to physical reasons and endanger himself. and the safety of those around them. In addition, operators should pay attention to clothing, preferably wearing a helmet and safety shoes.

Secondly, the overall inspection of the excavator should be carried out. Check whether there are abnormal conditions such as oil leakage and cracks in the working parts of the oil cylinder, traveling device, slewing device and engine. If abnormal conditions are found and the operation is still carried out, the excavator will be seriously damaged on the one hand, and on the other hand, it may occur during the work. Terrible phenomena such as machine failure and machine out of control endanger life safety. So if you find that the machine is abnormal, please contact the service personnel of the local agent to solve the problem in time. Check whether the work lights and wipers can work normally, clean the windows and rearview mirrors to ensure a good view during work, tidy up the interior of the cab to obtain a spacious and comfortable operating environment, and prepare water bottles to ensure that the body can be replenished in time during work moisture. When demolishing abandoned buildings, grabbing wood and steel, etc., check whether the protective fences in front of and above the cab are firm.

Finally, confirm the working environment of the excavator. There are often workers who rest or hide from the sun under the counterweight of the excavator. Make sure that they evacuate before the engine starts, and prohibit other personnel from standing within the excavator’s digging radius. If the crushing work is about to be carried out, it may cause broken If stones are scattered, consideration should be given to expanding the scope of “personnel prohibited from entering”. If you are about to work in a swamp or a quagmire, consider whether the environment can withstand the grounding pressure of the excavator. If necessary, place a large iron plate in advance to prevent the excavator from falling into the swamp or quagmire. If excavation work is carried out on urban streets, ask professionals in advance whether the excavation work will damage sewer pipes and underground cables. Reckless excavation may easily cause sewage to be sprayed or the excavator to be connected to high-voltage electricity.
