Importance of mechanics on CAT excavators

Heavy equipment are bound to breakdown given the fact that they are compelled to work beyond their limits. This at many times take a huge toll on the heavy equipment and it suffer major breakdown which is rectified only with the intervention of a mechanic or an expert who know how to fix earth moving machines. This gives rise to the importance of a genre of men without whom the industry will have a hard time moving ahead. We require mechanics for all sorts of gadgets. Right from the Television fitted in our drawing room to the air-condition/heater in our bedroom, all has the tendency to breakdown at some point of time and to fix that we need a mechanic. Similarly, the construction industry depends heavily on the mechanics who charge a good sum of money for their services. But not all mechanics are paid handsomely. It is only those who have the required level of experience and the knowledge to resolve issues are sitting at the top and rightfully minting money.

Excavator is kind of a blue eyed candy when it comes to heavy equipment for construction houses. The reason is it is meant to do all kinds of work barring few. One only needs to change it attachments and get the desired things done from this machine. Therefore an excavator becomes prone to often breakdowns. Irrespective of the company that produces excavators, during the passage of time you will find it giving up slowly and steadily and this is where you see the need of a mechanic the most. The moment it starts giving issues, you got to call the mechanic to fix it. Knowing the importance of the excavator in your business, you just can’t afford to neglect the issue or else it will crop up to something magnanimous and will then become a pain for you.

Cat excavators though are renowned all over the world for its efficiency, caliber, high performance and reliability it may still fail to work if proper care is not taken from the beginning. Simultaneously, any part of the CAT excavator can catch up with a problem at any juncture. It might give you some signals with the snarling sound. The operator has to understand it then and there or else the problem may aggravate and may result in replacing the part completely.

Alternatively, every part of the machine comes with an expiry date which may or may not be printed on the part. Being a CAT excavator, it may be possible that a particular part of the machine loses it vitality few months after its expiration date but it will expire some day or the other. Post which you need to get in touch with a mechanic to get the stuff replaced. You doing it on your own can lead to more complications and is also certainly not advisable. CAT company also has mechanics of their own who services the machine but construction companies has their own preference when it comes to mechanics and therefore it is important that one must be sure that they are dealing with an experienced one who knows his work well.

In order to merge two cities or places that is divided by a huge mass of water, we make bridges. Bridges that are strong enough to carry the load of heavy vehicles and cars all running at the same time over it. In order to build something that needs to be so strong, one can easily imagine the kind of heavy equipment that were used to construct such a bridge. The kind of heavy equipment that one can see in a construction or a mining site may not be very useful when it comes to construction of bridges over the water but if we are building a bridge covering a small area that has more of land, then the utility of equipment like backhoe loaders or an excavator becomes essential.

Building a bridge requires deep study of the location and skilled men who can execute the work. An operator who has been working all his life operating machines in a construction site may not find this work as his cup of tea and may probably not even understand how to go ahead with a given task. It is because the kind of work he has been doing all his life is entirely different from the work that has been assigned to him.

Utility of an excavator:-

Heavy equipment like an excavator are ideally used for building bridges that does not have a huge water body beneath and it needs certain degree of excavation to be done. Excavators are usually required for building bridges. Simultaneously, it has the capability to pull out the dirt from one place and put it on the truck. Though an excavator may not be required while building bridges over a huge water body or perhaps its use is limited during the initial phase of the construction and then it is replaced by other heavy equipments.

Bulldozer is needed to level the roads:-

A bulldozer is primarily required at the time of building roads on the bridge. There are used to level the roads over the bridge. The roll of a bulldozer is also quite limited and not used extensively during the construction of a bridge.

Heavy crane bridge building machine:-

In order to build big bridges, you require huge cranes that will help to put the slabs on the face of the pillars. It is unimaginable to place those heavy slabs without the involvement of a heavy crane. These cranes are initially used to give a structure to the bridge and once the structure is formed, the slabs are placed over it with the help of these cranes. Unlike an excavator or a bulldozer which may have limited use, these cranes are extensively used during the construction of big or small bridges.

Since the making of two bridges are not the same, crane manufacturing companies have come up with different types of cranes required for the construction. Each type of crane is meant for constructing a specific kind of bridge. They comes in different shape and sizes and it varies depending upon the sort of bridge that needs to be constructed.

The Latest Excavators Of Asia Are Ruling The Construction World

After the manufacturing of the latest excavators in Asia and its landing in the global market, a friendly business deal has smacked between CNH industrial and Sumitomo Construction Machinery.

Korea was the first country to evolve Hyundai R430LC-9A, which is a European unit. It was an excavator of class crawler type whose weight is 43 tonnes. It perfectly bridged the wide gap in the gamut of Hyundai beginning from 38 tonne R380LC-9A to 48 tonne R480LC-9A.

A critical study on Asian Excavators

Finland was the country which purchased the first unit of excavator from Soumen Telakone and is now able to dig out the heavy rocks with ease, as the getaway force of the equipment is 20,411 kg. The Cummins QSL9-Tier4 Interim/Stage IIIB engine of R430LC-9A provides a measured power of 231kw to give out. To increase the speed of the engines, the power utilizes the fuel in Xtra-High Pressure Injection system to carry out a continuous gush of condensed fuel across every engine. The operator can pick up any of the three available working modes-S for Standard, P for Power and E for Economy. This selection of working mode is invariably dependent on the type of job to be accomplished. It is known as Computer Aided Power Optimization and this system was present in the previous models of 9A series.

The three recent models of excavators of the E-series of Liu Gong attract the attention of every heavy equipment user. The updated models of the excavators 922LC and 925LC are 922E and 925E respectively. Among these models, 930 is the brand new one which has just knocked the doors of the construction industries.

The functional weight of 922E excavator is approx.22 tonnes with a digging capability of 6595mm. The weight of 925E is 25.5 tonnes and can make an underground passage of 6925mm. The excavator 630E weighs 31.3 tonnes whose highest depth of digging is 7300mm.

Construction experts prefer 922E to 922LC because the former has 8% more fuel efficiency and can dig grounds at least 5% better than the later one. Liu Gong has designed these machines with six working modes namely Fine, Power, Lifting, Breaker, Attachment and Economy. These excavators also contain automatic fluctuation of two-way velocity which enables the operators to switch to fast mode in normal ground conditions and slow mode when the equipment is working on rocky surface.

The new excavators are installed with Yanmar engines along with integrated Flow Pump System. This integrated pump system makes use of the technology of triple-oil pump for constant travel, enhancing the performance of digging and loading. Apart from these, the other exciting characteristics are the inclusion of a perfectly designed dozer blade to minimize the over-spill while levelling and a sound balanced operation for digging along the wall boundaries and trenches.

No doubt, these excavators of latest design from the Asian countries are ruling the construction field making the work smoother and easier. But while choosing the excavator of your need demands for a complete understanding of all the job requirements which you are planning to carry on with these modern excavators.

Almost all the projects of pipeline construction occurs mainly in rural areas and this construction work can be carried out in all climatic conditions. The receiving of effective and timely supply of logistics can appear as a major challenge because of the inferior infrastructure which is a very common case while carrying out the operations of pipeline construction. Moreover, heavy equipment plays a vital role in constructing the pipelines. You should have a proper knowledge of the heavy equipment before you take on the job of pipeline project.

Heavy Equipment for Pipeline Construction

  • Dozers: – Dozer is used to clear the land where the pipeline is going to be installed. The land is levelled using the dozers to enable the workers to construct the pipeline there. Here, they are mainly used for cutting and grading. Dozers which are generally used in pipeline jobs differ in sizes according to the job requirement.
  • Shovels: – Though shovel is not a heavy equipment, still it plays an important part in the construction of pipeline. They are used to dig, lift and shift huge objects required for pipeline jobs. They are one type of excavator and power shovels which are big in size is used during the work.
  • Backhoe:- The employees use backhoe to excavate the trench of pipeline. The land which has been excavated while carrying out the work of ditching is temporarily piled on the inactive side of the trench that means where no work is being done. The depth of the excavated ditch depends on the diameter and width of the pipe to be installed.
  • Pipe bending machine: – Each joints of the pipe to be installed are suspended along the right side which is adjacent to the unearthed ditch, and arranged in such a manner that it become gettable to the personnel employed in the pipeline job. The pipe-bending machine bends every joints of the pipe to the prescribed angle at places where there is a notable underground curvature and where it is needed to change the path of the pipeline. The pipe-bending machine includes Motor Grader, Motor Crane, Air Compressor, Pumps, Skid Truck and many more.
  • Side Boom Tractors:- The collections of the pipes are lowered into the trenches through the use of side boom tractors. The trench then is filled again with the help of bladed equipment like shovel, tractor and others.
  • Dump Truck: – Dump Truck is heavy equipment used in pipeline installation. It is used to carry loose materials like dirt, gravel and sand which can be purposeful for the pipeline job. It comes in a lot of types and the contractor should choose the right one to complete the work perfectly within the said time limit.

 

After the backfilling ad testing work of the pipeline completed, the disrupted ground is restored once again to its initial look. Construction of pipeline is not an easy job and it calls for some maintenance too after the work has been done. The inspectors of the project have been assigned with the job of monitoring and supervising the constructional work which they have to perform with great care.

Excavators are heavy equipments used for mining, digging and moving bulky objects. There are different types of Excavators. Here are top 10 fantastic types of Excavators.

Compact Excavator-It is that type of excavator which is basically a wheel vehicle with backfill blade and boom swing that operates independently. It can weight approximately 0.7 to 8.5 tonnes. Its structure has three separate division .The first division is house second one is undercarriage and lastly the workgroup. The hydraulic motors assist in travel functions as well as rotating the vehicle.

Dragline Excavator-Dragline Excavator finds its application in civil engineering and mining of surfaces.

It his divided into two categories

The first categories are cranes which are used for lifting materials. It is heavy in size and is provided with winch drum situated at the front side which acts as a dragline.

The second category is relatively smaller than the first category and is used for civil engineering purposes like constructing roads, bridges, port etc. It is also used for cleaning ponds and canals as well as driving heap rigs.

Wheel Excavator-This type finds application in surface mining. It is very large in size. It has a large round wheel as it name suggests with an arrangement of scoops which help in its rotation. All the materials are carried away from the machine by the discharge boom.

Reclaimer– A Reclaimer is a type of excavator which is used for handling large objects and eliminating heaps of materials. Reclaimers move on a rail between stockpiles. They perform all the instructions with the help of a remote control. All the modern reclaimers functions automatically whereas the older reclaimers are operated manually.

Digger Excavators-Such Excavators are heavy equipments and also has three separate divisions which are house, undercarriage and workgroup. The house comprises of boom and sticks. The second division which is the undercarriage consists of wheels and tracks. It is operated by cables.

Dredging– This vessel is used for cleaning and collecting the sediments and silt deposits in the bottom of the seas or lakes and disposing them to another place. Dredging helps to keep the seas and lakes traversable which would have otherwise become swallow due to presence of silt deposits making the seas and rivers unsuitable for navigation.

Apart from this dredging is also used for making harbours and channels in the sea for accessibility of larger ships. Other uses of dredging include mining of ocean floor, mining of sea beaches that are badly eroded by gales, eradicating garbage and debris, land reclamation etc.

Steam Shovel-The first Steam Shovel was invented by William Otis in the year 1839.

This excavation type is a large machine powered by steam. It finds in application in moving soil and rock. Steam shovel has contributed heavily in public works which dates back to 19th century. This equipment finds its application in constructing rails, roads and canals. They are also used for digging canals, building roads and railways and for mining purposes.

 

Vacuum Excavator-Vacuum Excavator is a vehicle which is used mainly for removing debris on land that is heavy. It is also used for eliminating soil from hole. Its structure consists of a suction nozzle with two knobs which the operator holds with his hands to grip it. For cutting soil and sucking up debris it has a tooth situated at the end of the tube.

Trencher-This type of Excavator is used for mining trenches, deploying drainage. It comes in different sizes and models. There are four different  kinds of trenchers includes Micro Trencher, Portable Trencher, Chain Trencher, Wheel Trencher.

Slurry Wall Excavator– They are used in the construction of concrete walls in those areas which are situated close to ground water table to block the walls enclosing tunnels.

In a construction project, grading is meant to be the process in which a base is created for the construction. The machine or equipment that is used for this purpose is termed as a grader. There are different names for graders that are very commonly used for this purpose such as a road grader, a maintainer, a blade or it can also be a motor grader. The typical or traditional model of a grader has three axles, one engine and a cab that is positioned on the rear end of the axles. Other than the grader, the other very important machine or construction equipment that is most frequently used is the excavator. It is a heavy construction machine that has a stick, a boom and a cab with the controlling engine. The task of excavation by an excavating machine is however accomplished by steel ropes and winches. In case the excavators are hydraulic excavators, the functions are performed by the hydraulic fluid.

Use of graders:

The most common and wide spread usage of graders are on the roads. For maintaining the gravel roads as well as the dirt roads, the heavy construction equipment named graders are used. The function that is performed by these is to create a base or flat and wide surface area for the roads to place the asphalts on the base. Another important role that the graders can perform is the building of soil foundation for the large constructions or buildings. In countries where on the sides of the highways, a cross section or construction like a ‘V’ shape is made, it is done by the graders. The graders can also cut ditches very efficiently.  Other than these construction jobs, the graders can also remove trees, after construction or post demolition debris, or it can also remove rocks. In a single statement, if you want to comprise all the functions of a grader, then it must be said that a grader creates the surface or base of any construction or other heavy load works so that the later equipment can perform their duties.

Use of excavators:

The basic usage of an excavator is at the digging sites or trenching sites. The long stick, boom and cab that are the main parts of an excavator, very efficiently performs the task of trenching or excavating. Not only digging a trench, the excavators are used for the archaeological excavation sites also where digging and removing the unimportant large amount of debris can be performed only by an excavator. The excavators also perform their task in the process called the “earth moving”. These excavators can be of two types, either a tracked excavator or a wheeled excavator. Both type of excavator can perform with equal efficiency. However, the tracked excavators are more preferred than the wheeled ones as they have the better floatation or it can be simply said that the tracked excavators can move easily on any platform, whereas the wheeled ones have this limitation. Otherwise, they are very versatile.

Try Caterpillar 330 excavators at your work place and get all the solution of your problem

Caterpillar 330 is a type of excavator that comes with great attributes. As the equipment can serve you a variety of works you can definitely consider this item anytime you require it. Excavators help to dig up materials or soil. This equipment is very strong and also possesses the right potential to carry a great loads and a lot of materials within a short time.

Therefore if you are planning to buy an excavator then you definitely should check out whether its engine is good or not.

 

Bucket:

You know that heavy equipment can take huge loads and perform good works. In order to perform different types of works it is highly necessary to have good and proper specification. Bucket is another important part of the excavator. However, different types of excavators have different buckets. The size of the bucket is different from each other.

Other specifications:

There are several other specifications that actually important for running an excavator. It actually differs from machine to machine. Therefore, you have to make it clear that whether the excavator has perfect specifications or not before purchasing it.

 

You also want to know the fact that how you run an excavator. Don’t worry the process is very easy.

You have to start the important part of the equipment that is engine. Almost like the vehicles you have to start its engine. Therefore you have to turn a key to turn it on.

In order to run the excavator you have to be concerned over it. It has certain process that you have to follow. Without following such steps you will not be able to perform your works. Therefore, at first, try to get all the details about the equipment and then you can try this equipment at your work place.

Why Should One Be Using Caterpillar Excavators – Find It out Here

A construction site is filled with heavy equipment of different kinds and they all are working all day busy constructing a building for us to live. But one thing we must all understand that without the help of these heavy equipment, things won’t look as simple as we see it to be. A construction company needs to have all sorts of machines. Right from a bulldozer to an excavator, they need it all to fulfil their business requirements.

Each machine has its own role to play and hence it becomes quite imperative to pick the right iron for the job. It becomes quite tricky to select the best available option when you are given too many of them. However, when you have a name like Caterpillar as an option, you may not think twice to pick that up. Therefore, it is wise to put Caterpillar machines to work and get the job done.

Cat is perhaps one such company which gives lot of stress to consumer’s demands. They leave no stone unturned when it comes to fulfilling customer’s requirements and pay special heeds to their needs. This is probably the major reason why many big construction and mining houses vouch for Caterpillar heavy equipment.

We would be discussing about caterpillar excavators and why should one have them in their corner. Let’s talk about the most recently launched Cat 320EL Hydraulic Excavator. Well, this machine can make the hard work look simple. It’s rock solid but has the potential to do the work with ease. It’s easy to move from one place to another and the control system is simply awesome. The operator won’t perspire doing the tough job and may even find him listening to some music while moving earth. Its capacity to lift things has increased by over 5% on a standard one and if we consider a heavy lift configuration, then that’s been increased by more than 20%. Like its earlier version, it has low emissions engine which not only increases its fuel efficiency but also boosts productivity.

Cat 320EL is fitted with C6.6 Acert Engine that has an electronically control the fuel pressure. It also includes a 3 layer fuel hoses and an electric pump which permits the use of biodiesel. In order to cool the engine, they have an air to air after cooler and an A/c condenser. The fan automatically adjusts to the temperature and keeps it cool. The engine of this model plays a significant role to keep down the fuel consumption without hampering its performance.

The machine is gifted with hydraulic horsepower which perhaps make it unique in approach and also more favourable as compared to other machines. It’s indeed the actual power behind the machine which allows it to do the toughest of the work with much ease. It has a back to back main control valve which helps it to increase its efficiency. It’s also blessed with a heavy lift which allows the machine to lift a lot of stuff at the same time and complete the work at a much faster pace.

Knowing all these, it would be absolutely naive to think of going for any other equipment which may not at all have these features and if at all they possess it, it may be short lived.
