Talk Of The Town: Bulldozers
Is that a jet? Is that a Chopper? Nope. It’s the sound of a bulldozer. As many in the heavy-duty industry may be familiar, what may seem like a complicated mechanism of construction equipment are contrary, designed to make our lives easier. Whether it is land clearing, digging, excavating, or working in extreme weather conditions, bulldozers are true to their name; Strong and resilient pieces of equipment designed to power through any project. Since the reputed Earl Mcleod first invented the bulldozer in 1923, this type of heavy machinery has witnessed several advancements through its time in the industry. However, the core of its nature remains the same.
These machines are essentially powerful crawlers that are accompanied by a dozer blade often, like that of a tractor. The make and design of this machine, enables it to perform rough duties while possessing great ground hold and mobility. This earthmoving capability can be credited to its unique standing feature – the dozer blade. The blade is in essence, the attribute that enables peeling layers of soil and pushing it forward like that of a tractor, completing excavation jobs at considerable ease.
An Overview of the past
The success of its use is rather evident among leading manufacturers adopting this type of equipment and making unique advancements suitable for various projects. Companies such as Komatsu, JCB, CAT, John Deere, and so on were the initial investors in this technology, creating influential ripples within the industry. Over time, many other companies in the industry contributed to this innovation with tweakings of their own leading to better engines, implementation of smart technology, improved mobility as well as, hydraulic arms. Although it is said to have been initially established from the idea of a Kansas farmer, Earl Mcleod, this equipment originates from several other inventors at the time who worked to improve the use of the tractor. This led to versions of trial and error that eventually lead to the first official bulldozer.
Types of Bulldozers and its uses
There are many several types of bulldozers in the field; however, three of them seem to be the most prevalent within the construction industry.
Crawler bulldozers are a blend of wheel loaders and tractors. These machines are similar to tractors in the sense that they are excellent for moving large and heavy materials off the ground while utilizing their rippers for eliminating unnecessary objects and land clearing. The thing that sets it apart from a crawler is its front-mounted engine giving it the ability to ‘push-through’ material.
A mini bulldozer or a mini dozer is simply a compact version of the bulldozer. It is often favored over its larger counterparts due to its maneuverability. Its size makes it the perfect choice for working on smaller projects, and smaller tasks such as grading, back-filling, or even driveway construction.
Compared to the crawler variations, the wheel dozers have the upper hand when it comes to mobility. Their ability to maneuver through dense terrain can be credited to their superior tires, smaller axis, and hydraulic steering. Unlike the wheel loader which it is often confused with, the bulldozer is ideal for flattening the ground, while the wheel loader is usually used for moving parts of the ground.
Uses and Benefits
Bulldozers, regardless of their type are a popular choice for demolition purposes. Their unique selling point lies in their size and large extensions. Apart from demolition, the use of this equipment often varies from earthmoving, constructing roads and pavements, as well as land clearing. They offer benefits on a multitude and are undoubtedly an excellent addition to every project. These machines have come a long way since they were initially introduced to the market, wherein, their most common purpose was often seen in farming. However, in today’s world, they can be used in the construction industry largely to promote safety, while increasing time-effectiveness and improving productivity on a job site.
