Heavy construction equipment is one of the most important elements in today’s world, where there is a continuous growth of the construction industry and new constructions are taking place every day. That is the reason, why the heavy construction equipment supplying job has become such a popular one in the industry. If you too are thinking of starting such a business, it is important that you know all about this.

Types of heavy construction equipment:

Many people do not know much about the different types of heavy construction equipment that are available in the market. These are used for various purposes. Some are used to assist in the construction and some are used indirectly in carrying, loading and unloading raw materials.

Some of the common heavy construction equipment that you will often get to see at a construction site, on the roads etc. includes –

  • Cranes
  • Backhoe
  • Loaders
  • Excavators
  • Forklifts
  • Bulldozers
  • Concrete mixers.

These are just a few of the many that you will frequently get to watch. However, there are many others that are not used as widely, but are meant for job-specific tasks. These are usually used during earthquake damage, storm damage and such other damage cleaning.

How can you access one?

The heavy construction equipment is not very cheap. There is no denying the fact that you will have to spend a lump sum amount of money, if you want to own one. Hence, it is always a better idea that you hire them, instead of owning them. This way, you will be able to access the ones that you would require for a particular task and you will not even have to spend a huge amount of money to own them and take care of them.

But of course, the heavy construction equipment is something that not everyone and anyone would require. It is mostly required by the construction industry companies and services. So, if you own such a company, it is always advised that you choose one that you can own, rather than hire it. This is because, hiring it every time will only cause you to pay more.

Choosing the right heavy equipment:

Once you have decided, whether you want to buy one or hire one, you need to check out a number of factors. These would include –

  • Brand: The right brand is very important. With a branded company, you will be able to have the peace of mind regarding its function and life.
  • Condition: In case you are buying used heavy equipment, make sure it is in a good condition.
  • Papers: The papers of the used heavy equipment must be proper, otherwise you will not get a permit and insurance, if you wish to have one.

If you take these factors into consideration, it will be easier for you to make a choice. In case you are still confused, always consult a skilled professional, who has years of experience in this field or a dealer of heavy equipment. They will be able to guide you properly.

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.

Caterpillar D7E Dozer

One of the biggest problems that majority of the construction companies were experiencing was their dozers consuming more fuel and they were indeed looking for. Something that can do away with this maximum fuel consumption and pays more attention in higher productivity. Many heavy equipment manufacturing companies have come up with dozers making tall claims but they were somehow not able to prove their metal when were put to test. Caterpillar was also experiencing difficulty in producing a dozer that can maximize its productivity by consuming less fuel. However, in the year 2009 they were able to produce D7E Dozer that was way better than its contemporaries produced by other companies.

It is believed that since 2009 many customers who were using CAT D7E dozers on their jobsites were able to save gallons of fuel which was otherwise not possible in the earlier versions. When we are talking about low fuel consumption it did not happen by compromising its performance. CAT made sure that the product they would manufacture should be of top notch quality giving the same user experience to the end users. This is why people who were using D7E dozers never had any issues with its performance and if anybody had any issues, CAT proactively got rid of those problems.

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.

Bulldozer is a heavy constructional equipment that is mainly used to build roads and glade the land. In the olden days, most of the bulldozers were in the form of tractors. The farmers used it to plow their field. But now, it has become more useful with many modifications such as rear ripper claw. At present, it has become an unavoidable part of the construction industry. Apart from that, it is also used extensively in mines and various projects of engineering.

Applications of a bulldozer

You can use a bulldozer for variety of purposes. Some of them are given below:

    • Building of the roads: – The first step to build a road is to remove the topsoil. It is very important because the topsoil contains large quantities of moisture and organic bits and pieces. This removal of the topsoil helps to increase the stability of the road. You can easily push aside the topsoil with the help of a bulldozer. It leaves an opening for the construction of the road. This opening can be filled with rock-strewn. Many people use the bulldozer to smooth the cram of the opening.
    • Demolishing old unnecessary structures: – Another important use of bulldozers is the act of destroying and demolishing old and unnecessary properties. You can knock down a building quickly using a large bulldozer. Bulldozers that are used for demolishing purposes comprise of a powerful cab to protect the user from any kind of injury. After knocking down a derelict property, you can use the bulldozer to mound the debris and polish up the whole area.
    • To move huge quantities of earth: – The bulldozers are extensively used for pushing away large quantities of soil and earth. It can set aside the piles of organic matter by making use of the blade. You don’t have to use any backhoe to uplift everything and keep it aside for later disposal. Sometimes it is attached with various kind of digging machines or backhoe. This backhoe is used to uplift any material from the excavation site which is later pushed away by the bulldozer to some distant places.
    • For construction purposes:- Bulldozers have many different purposes to serve in the process of construction. Most of the big projects of construction need widespread preliminary work of the site which the workers can smoothly do with the help of the bulldozers. It can easily strip off the vegetation for digging the pit.
    • For clearing enemy’s base: – The armies use bulldozers to clear the enemies’ bases and other infrastructures. They use armoured bulldozers which protect them from the attacks of enemies.
  • For deforestation:- The sharp blades of the bulldozers are used for cutting down large trees.

 

As it goes on tracks, it has great grip against the land. Bulldozers are used by the workers to carry out the work without any difficulty. If you too need a bulldozer for any kind of above mentioned work, then go and get it today.

Almost every item has a depreciating value and finally that item becomes obsolete and ceases to function. Same is the case of heavy equipments. Machines used in construction or in mining sites are quite expensive and after having used them for few years, you may find a newer model with certain changes in the technology being launched which you tend to purchase. That doesn’t mean the end of the existing machine. It is simply not the end of the story for the old one but perhaps it only suggests that it’s time for it to gear up for something new.

Here we would be speaking about what can one do with a used bulldozer. Would selling be the right option or simply giving it on rent would be appropriate. Let’s try to analyse what makes more sense for a person having used a bulldozer for the last few years.

Selling off the machine:-  If you have used the bulldozer for 3-4 years and if you are of the opinion to sell off the old iron and buy an upgraded model, selling off the bulldozer would make more sense. With the help of the money you get after selling the old machine and adding few extra bucks will help you get the new one. In order to sell the used bulldozer, you can post a classified on a local newspaper and give away your contact details. A bulldozer which is being used for 4 years can still fetch you a good price and hence selling the machine should turn out to be a good option.

You can also list the item on an online selling site. There’s a new trend wherein people are prone to buy things online rather than visiting a store and buy the stuff. Though buying a used bulldozer may not sound same as buying apparels from an online store, still it has its own importance which is clearly reflecting with the growing popularity of online selling portals. People do make their way by registering themselves in such online selling sites and are quite content after buying heavy equipments from there. You also make use of this opportunity and can list the bulldozer on the site. Giving proper description of the item will make it easier for the buyer to understand the position of the machine and help them to judge if they should be going ahead with the deal.

Putting it on rent:-  To a larger population, renting the machine would make more sense. However, that depends on the situation that makes them take the decision. For instance, you’re certain that you would not need your bulldozer for the next few months, it’d be better to give the machine on rent. You can earn some money as monthly rentals and once the contract is over, you can take it back. A word of caution would be to communicate very clearly about the maintenance and servicing part to the taker. Or else, they might not take proper care of the dozer and it may wear it sooner than expected.

Caterpillar D6 or D6T Bulldozers – Which One Must You Go For

Bulldozers play a very important role in the construction industry. With the help of a bulldozer, the land is levelled and the place is made suitable to walk on. It paves the way for the people to move on it and allows them to work on the construction site. It is believed that bulldozers were the first heavy equipment to have ever been built for construction purpose. Prior to this, manual labour was the only source that was used for construction. However, this belief of many has often been challenged by others who have their own claims in this matter.

Something that has come out of various discussions held in different forums is the fact that it would be difficult for the construction business to survive without the existence of a bulldozer. There are many companies who claim to manufacture quality bulldozers. However, here we would be speaking about the Caterpillar D6 and D6t bulldozers and will try to understand which one should a company go for.

Let us first discuss about Caterpillar D6 dozer. They are one of the oldest models of bulldozer that has been produced by Caterpillar. It was first produced in the year 1935 and was fitted with 3 cylinder D6600 engine which had a horsepower of 45hp. It later introduced 2 more series which was powered by D4600 engine thus giving more power to the machine.

More than 2 types of blades can be installed in a D6dozer. The first one is a straight blade which is a shorter one and has no lateral curve or side wings. These types of blades are used for fine grading. Then we have the universal blade which is completely contrary to the straight blade. These types of blade are tall and are much curved with large side wings which are used to carry huge load of material. They also have a combination blade which is more like the straight blade and has less curves and smaller side wings.

If we talk about the rear of the dozer, it can be installed with stuffs that compliment the front blade. In order to add weight to the machine, large slabs of steel can be added to the rear which becomes useful for heavy dozing works. It also had a Cable control unit which was used to pull towed scrapers. This has now been supplemented by hydraulics. Installing a linkage with plows in the front makes it suitable for agricultural purposes.

The D6T dozer is comparatively better than its predecessors. It has earned its goodwill by proving the kind of machine it is. Right from generating high productivity to getting a resale value for it, you can remain assured on every piece of it. It has a horsepower of 205 hp much more than D6 dozers. It comes handy in work like dozing, scraper work, ripping, constructing oil pads, and many more such things.

Operators comfort has been given a lot of attention and stuffs have been redesigned in such a way which makes works easier for the man on the seat. With ever increasing wants of the consumer, With more features being added to the D6t dozer, it seems to be an ideal equipment much to the wants of the present day consumers.
