Powertrain.
The core structure of the excavator loader is the powertrain. The powertrain of the excavator loader is designed to run freely over a variety of rugged terrain. It has a powerful turbocharged diesel engine, large deep-geared tyres and a cab with driving controls (steering wheel, brakes, etc.).
Loader.
The loader is assembled in front of the equipment and the excavator in the back. These two components provide completely different functions. Loaders can perform a variety of different tasks. In many applications, you can think of it as a powerful dustpan or coffee spoon. It is not generally used for digging, but is primarily used for picking up and carrying large amounts of loose material. It can also be used like a plough to move the earth, or to level the ground like a knife to butter bread. The operator can control the loader while driving the tractor.
