Loader tracked is an engineering vehicle consisting of a chassis tracked by a loader to dig and load material. The history of the tracked loader can be defined by the three evolutions of their design. Each of these evolutions makes the tracked loader a more viable and versatile tool in the excavation industry. These machines are capable of almost every task, but do not master anything. A dozer, excavator, or wheel loader will come out performing loaders tracked under a set of conditions, but the ability of a loader tracked to perform almost every task on the job site is why it remains part of many fleets of the company.
The first tracked loader is built from a tractor track with a loader built in scratch. The first loader is a cable operated like a bulldozer of that era. This tracked loader does not have the ability to dig in hard ground, but so does the dozer that day. They are mostly used for moving stockpiled materials and loading trucks and trains.
The first major design change for loaded loaders comes with the integration of the hydraulic system. Using hydraulics to power the loader connection increases the loader's power. More importantly, loaders can apply downpressure to the bucket, further increasing their ability to excavate unworked soils. Most of the tracked loaders are still based on the bulldozer equivalent. The weight of the machine is still on the front of the track along with the heavy loader component. This causes a lot of problems with the heavy wear of the front wheel idler and undercarriage in general. The Caterpillar 983 track loader, the second-largest loader ever made, is known for heavy undercarriage wear.
The hydrostatic drive system is a second major innovation that affects the design of the loader being tracked.
Tracked loaders have become highly sophisticated machines, using hydrostatic transmission and electro-hydraulic controls to improve efficiency. Until the increase in popularity of the excavator, the loaded loader has little competition in excavation and job loading.
