Definition of loader
Loader is a tractor machine that is considered as a set of road building and construction machines. This device is a set of hydraulic mechanisms mounted on its own tractor. It has not very long arms (compared to other arm road construction machines) and instead has a bigger cup.
Types of loaders
rubber wheel loader< /b>
It is the most common type of loader that is made in many different sizes. This type of loader is often made with lower powers than chain wheel types. They are faster and have much more maneuverability. Rubber wheel loaders sometimes have problems when working on very soft or muddy soil or steep surfaces. The reason for this is the less friction of the surface of the rubber wheels with the ground. This amount of friction can be controlled to some extent by adjusting the air of the wheels. Also, rubber wheel loaders may have problems when working on the ground with sharp stones. A solution has been devised for this problem. Special chains are intended for these loaders, which enables their activity even in mines. Of course, thick and ivory tires are also prepared for all kinds of uses. There are two general types of wheel loaders: back-breaking and conventional. The waist type of these loaders has a joint in the middle of its chassis that gives it high maneuverability. This joint works with hydraulic jacks
Chain wheel loader
Chain wheel loader due to more friction with the ground and also stability to move on sharp stones It has some advantages over a wheel loader, but overall they perform the same. Backhoe loader These machines are actually small loaders that have an excavator on their back and are used for light work. All their general characteristics are the same as loaders and mechanical excavators. Due to the dual purpose of the back loader, this device is used in many small projects, especially if the project is related to ditch digging. .
Application of all types of loaders
Rubber wheel loaders
Rubber wheel loaders are mainly used in operations that require more speed.
backloader
This model has a proper and controlled performance of urban excavations, and it also causes much less damage to the surroundings of the excavation site in small urban constructions.
Using a loader instead of a forklift
Sometimes they install other tools on loaders instead of cups that add new capabilities to them, such as grabbing and lifting objects. Or even a forklift-like function.
Using a loader instead of a pipe
There are receiving rakes in the loaders that are closed instead of the cup and make it possible to use the loader to carry and open pipes and tree trunks.
track loaders
Track loaders work like wheel loaders except that the low pressure they exert on the ground allows them to work in terrain that is not suitable for wheel loaders.
Their high friction with the ground makes them able to make the most of the engine's power to break the ground, and because they have chains, there is no risk of tire tearing when working in areas with sharp stones.
Chain loaders are able to move on surfaces with a side slope of 35%, while this figure is 15% for a rubber wheel loader. Also, a chain loader can climb a slope of 60%, while this figure is limited to about 30% for a wheel loader.
The speed of the chain loader is much lower than that of the wheeled loader, for this reason, in cases where the distance between transporting materials and returning to the loading place is long, the efficiency of this machine is low compared to the wheeled type.
