what are the classification of loader?

Loader is a kind of engineering machinery with high operation efficiency, which has a history of nearly 50 years. Not only the performance quality is gradually improved, but the types of loader are also rich. So, what are the classification of loader?

According to different use requirements, powertrain system, etc., the loader development has formed different structure types:

1.  Classification by walking system structure:

(1) Tire type loader: a loader composed of a tire type special chassis as a walking mechanism and equipped with a working device and its control system.

Advantages: good mobility, can operate on the highway, convenient transfer, flexible operation, wheel loader is the steering wheel control steering, cylinder drive the front wheel steering. The turning radius is small, suitable for the narrow site operation.

Disadvantages: can not be in the hillside steep, potholes water, soft soil, muddy road work.

(2) Crawler loader: a loader composed of crawler special chassis or industrial tractor as the walking mechanism, and equipped with a working device and its control system.

Advantages: large traction, good off-road performance and stability, large climbing ability, small turning radius, you can work in the harsh conditions of the site environment.

Disadvantages: it can not walk quickly on the highway, the transition is not convenient, the operation flexibility is poor, and the crawler maintenance cost is high.

2.  According to the different use occasions, it is divided into:

Open air loaders and downhole loaders (the vast majority of loaders produced and used in China are open air wheel loaders. Downhole loader is designed according to the underground working conditions, the engine discharge and noise elimination, the machine height, working device and the layout of the driving operating system, on the basis of the open loader)

3.  Different classification of powertrain:

Mechanical transmission, hydraulic mechanical transmission and full hydraulic transmission three kinds.

(1) Mechanical transmission wheel loader is only used in China for loaders with a bucket capacity of 0.5 ㎥ or less. It can generally use the transmission of a car or tractor.

Advantages: it has low cost, high transmission efficiency, can be dragged, convenient maintenance, etc.

Disadvantages: complex and laborious manipulation, clutch and transmission life is low.

(2) Hydraulic mechanical transmission wheel loader, hydraulic transmission wheel loader, currently dominant in China.

Advantages: hydraulic transmission has can make the loader smoothly inserted into the material pile, automatic speed change, will not overload the engine flameout, can ease the impact of the transmission system, smooth operation, reliable work and so on.

Disadvantages: large power loss, low transmission efficiency, high cost, complex structure, inconvenient maintenance. Its transmission system is mainly hydraulic torque converter and power shift transmission.
