Track Loader are engineering vehicles consisting of tracked framework with loader for excavating and loading materials
. They may be described by three development of their designs. Every evolution made the loader more feasible and adaptable tool in digging industry. These machines are capable in almost all tasks, however, master of nothing. This loader is out performed by the dozer, wheel loader or an excavator, but the capability of a Track Loader to perform almost all the tasks in the job site is the reason why it stays as a component of several companies' fleets.
The initial track loaders were assembled from tractors having scraped built loaders. The first produced loaders were operated by cables such as bulldozers of the period. These machines are not capable to dig in solid grounds. They were typically used for transferring stockpiled objects and loading railing cars and trucks.
1st major design that changes with this heavy equipments are from the additional hydraulic systems. By using the hydraulics for powering up the loader connection will increase the power of loaders. In addition, the loaders can apply the down pressure in the bucket, greatly increasing its ability for digging the ground. Most track loaders are based with the bulldozer, the weight of their engines were at the front half of tracks together with heavy components of the loader. This thing causes many problems for the heavy wear in the front-idler wheel and under-carriage in general.
2nd major improvement with the design of the equipments are their hydrostatic driving system. This machine had been sophisticated heavy equipment by utilizing the hydrostatic transmissions along with the electro hydraulic controls for the increased effectiveness. Until the high demand popularity of the excavator, Track Loader are in little competition with regards to loading as well as digging task.
