Mid range crawler dozers are widely accepted by customers in the construction domain

Working in a small space will not allow huge equipment and you have to restrict the use to either mid-range or small equipment. When we talk about heavy equipment, it is not only about those big machines that you often see at construction sites but it is also about equipment that you see in your backyard clearing the garden or clearing the snow off the road. You do not always need a big dozer to clear the snow from the road. Imagine if the road is not that big to accommodate a big dozer, it will not be able to complete the work. In such a situation what you need the most is a mid range crawler dozer.

The demand for the mid range crawler dozer has increased over the last few years. People have begun to realize that it is not all about big machines but at times we also need something smaller in size to get the work done. This is how people have understood the importance of such machines and has led to the growing acceptability of it. Before we speak further on this, we need to understand what category of machine come under mid range and what goes above that. Machines that have horsepower between 130 to 200 hp are in the mid-range category. Anything falling short of that is a small machine and machines that have more than 200-300 hp fall in the higher range of machines.

A reports also suggest that the mid-range machines play a dominant role in the construction industry which was not the case few decades ago. However, not everybody likes to purchase high range equipment and keep themselves content with the lower version. Irrespective of the construction company being a big one or just a newbie, they all prefer mid range machines. The maneuverability of such machines are simpler and faster and are therefore considered potent for work that is meant for small range as well as high range equipment. Caterpillar’s Dave Cusac feels that though some companies want mid range machines to have hp more than 300 but due to certain technical alignment, it has been limited to the range of 150 to 215 hp.

Mid range crawler dozers have varied uses. They are not just used for single category of work but are used for several purposes and this is what makes the machine more in demand. Case Construction Equipment brand marketing manager has bifurcated the use of the machine on the basis of the horsepower it possess. According to him, the machine with hp of 130 is used for construction of roads and bridges but not into residential construction. Machines with hp of 150 are also used for building of bridges and roads but they can simultaneously spread their wings into larger jobs. Machines more than 214 hp can be used for mining, overburden clearing and similar operations. Having said this, it does not mean that these machines do not have the capability to perform heavy duty jobs.

Top ten models of bulldozer

Manufacturers of heavy constructional equipment, farm and mining bring out innovative models of the machines with prototyping tools of the manufacturing companies. As these tools develop a clear understanding of the total effective cost, risk management and maintenance requisites, one can go ahead with confidence. This advancement in designing the models of heavy machines especially bulldozers slash the construction time and hence, enhances the speed time of the product marketing.

Different designs of bulldozers have their own applications in their respective areas. The skilled engineers use CAD tools to increase the productivity which in turn will reduce the cost making it affordable to the users.

List of top models of bulldozers

Fiat Allis FD-50 Bulldozer: – It is outfitted with an engine of Cummins VT28-C. Due to some rationalism in its marketing, the manufacture of this type of bulldozer has come to an end. FD-50 had the highest power of 600 hp with carrying a total weight of 80 tons.

Promtractor CHETRA HEAVY 40Ya Bulldozer: – The model of the diesel engine which the bulldozer uses is YaMZ-E856. Its fuel tank has the capacity to hold 1200 litres. Its main technical data indicates that this kind is less efficient as compared to the above said model with the maximum power of 590 hp and working weight capacity of 68.5 tons.

KOMATSU D375A-6 Bulldozer: – This kind of bulldozers uses a dislocation of 23 litres of the engine of KOMATSU SAA6D170E-3. The bulldozer can run at the rate of 15.8km/h. It is efficient with 645 hp power and carrying limit of 72 tons at its best.

Promtractor T-50.01Bulldozer:- Russian product which came into existence in the late 1980s. The width of the track is 740mm with the installation of U-shaped blades. Its power of 751hp with loading capacity of 93.5 tons makes it stand out from other models of bulldozer.

Caterpillar D10T Bulldozer: – D10 in 1970s was the largest bulldozer types. The latest T – type models use the cylinder engine of D10T-12. Both its power and lifting retention is low i.e. 671hp and 66 tons respectively.

Ch TZ T-800 Bulldozer:- This bulldozer is equipped with the diesel engine of 6-turbocharged cylinder. It has two back and four forward gears, but this machine is not efficient to give out more than 8 units when carried out to work of mining and removal of the debris.

KOMATSU D475A-5SD Bulldozer: – The capacity of its fuel tank is 1670 litres. The technical info shows that the bulldozer has the maximum power of 913hp and working weight of 113 tons.

KOMATSU D575A-3SD Bulldozer: – It has total 6 gears-three reverse and three forward. The bulldozer can hold maximum 2100 l fuel. The length of its machine is 11.72metres.

ACCO Bulldozer:- ACCO, an Italian company manufactured the world’s best designed bulldozer model in 1983. Due to some technical fault, it can’t be operated. It never got any appropriate occasion to show its efficiency.

Caterpillar D11T CD Bulldozer:- This kind of bulldozer uses the displacement of 32L of the diesel engine of Cat C32 ACERT. It can carry upto 113 tons of weight utilizing its power of 950 hp.

To sum up, the rapid advancement in the field of technology has definitely boosted up the designs of the bulldozers giving it a completely different look and efficiency.
