The first tracked loaders were built from tracked tractors with custom-built loader buckets. The first loaders were cable-operated like the bulldozers of the era. These tracked loaders lacked the ability to dig in hard ground, but so did the bulldozers of the day. They were mostly used for moving stockpiled material and loading trucks and rail ...
They are used to transport loose solid bulk commodities such as coal, ore, grain, and track ballast. [2] [3] [4] Plastic pellets and some finely ground material, similar to flour, are transported in hopper cars that have pneumatic unloading. The bottom gates on the pneumatic hoppers connect to a hose attached to industrial facilities' storage ...

Ballast cleaning removes this worn ballast, screens it and replaces the "dirty" worn ballast with fresh ballast. [ 3 ] [ 4 ] The advantage of ballast cleaning is that it can be done by an on-track machine without removing the rail and sleepers , and it is therefore cheaper than a total excavation.

A loader is a heavy equipment machine used in construction to move or load materials such as soil, rock, sand, demolition debris, etc. into or onto another type of machinery (such as a dump truck, conveyor belt, feed-hopper, or railroad car).
Track segments (i.e., trackshoes) that incorporate grouser bars are known as grouser shoes, and typically include one to three grousers. [3] Grousers are commonly used on construction vehicles such as bulldozers, loaders, and excavators. Grousers may be permanently attached to, or formed as a single piece with, the track shoe, or they may be ...
Skid-steer loaders are sometimes equipped with tracks instead of the wheels, and such a vehicle is known as a compact track loader. [7] Skid steer loaders, both wheel and track models, operate most efficiently when they are imbalanced – either the front wheels or the back wheels are more heavily loaded.
