Probably the 1st sign of development in any country youwill see is a marked increase in their infrastructure. One can see development of roads and buildings and bridges which are on going fast forward. Depending on the scale of the project there are large cranes and earth movers with lots of other high performance construction machinery. One of the most typically used machines on any construction site is the Track Loader. This is primarily an earth moving machine while it can be employed to move other construction materials like bricks and foundation stones. Let’s look a bit more closely at what a Track Loader is and how it works.

A Track Loaderis an engineering auto whose chassis is attached to tracks. Unlike most passenger or commercial autos which have wheels under their chassis, a track loader has tracks which makes very like amilitary tank. The front end of this has a loader attached to it which performs the digging and loading functions. While this machine has been about for a while now, there were 3 significant evolutions in its design.

With every evolution the Track Loader became a more handy and all around construction machine with multipurpose capabilities. Naturally the drawback to this is that these machines can do a little bit of everything but don’t have a particular specialty. The Track Loader fundamentally mixes the functions of the standalone machines into one – bulldozer, excavator and wheel loader. This multitasking ability is the primary reason why it is sometimes used on construction sites.

The look of the modern track loader started from the time when they were made from track tractors with scratch built loading extensions. They were modeled along similar lines to the bulldozers of the time and so were cable-operated. Like bulldozers, these machines were unable to dig into ground and were primarily used for moving material and loading vehicles.

Following this, the subsequent major design change which was incorporated into these machines was the integration of hydraulic systems. The benefit of using hydraulics was the overall power of the loader was increased. As a consequence of the increased power these loader could now apply downward pressure to the loading bucket which gave them the facility to dig the ground. At the time many of these track loaders would face a lot of wear on the undercarriage. The front idler wheels especially would get worn out faster than the other parts as the look of the loader was based totallyon the bulldozers where heavier parts used to be put on the front end of the track loader.

The subsequent innovation in this machine was the hydrostatic drive system. With the advent of sophisticated technologies like hydrostatic transmissions and electro-hydraulic controls, this workhorse of a machine suddenly turned into a complicated machine. In fact these were the machines of choice on most digs and construction sites till the introduction of advanced excavators. The excavators are quickly find favor with many construction companies due to economic factors as well as their flexibility of function.
