Do you know the pros and cons of Wheel Loader?

Wheel Loader China has made great progress after decades of development. Particularly commendable and proud of the Chinese people is that the annual production and sales of loaders have exceeded 160,000 units. In the Chinese market with international brands today, domestic brand loaders still occupy the vast majority of the market. In 1978, the annual output of China's loaders was only 1315 units, and the cumulative output was only 9454 units. Similarly, the annual output of Chinese bulldozers in 1978 was only 1909 units and the cumulative output was 11,923 units. At that time, the number of imports was large. By 1980, the cumulative imports reached 3,333 units. Especially in the late 1980s, imports accounted for nearly 30% of the market. In open-pit mines with suitable conditions, the use of wheeled loaders can highlight the following advantages:

Wheel Loader China

1. Wheel loader has fast walking speed, short working cycle time and high loading efficiency. According to the mine calibration data, the wheel loader with a bucket capacity of 5 ~ 8m3 can reach speeds above 35km / h, which is 30 ~ 90 times faster than an electric shovel. It only takes 40 ~ 45s per working cycle, and the average shift production capacity can reach 3500. ~ 4000t, average labor productivity can be increased by 50% ~ 100%.

2. Wheel loader has a lighter weight, which is equivalent to 1/8 ~ 1/6 of the same bucket capacity of the excavator, saving a lot of steel, the manufacturing cost is only 1/4 ~ 1/3 of the excavator, and the price is higher than the excavator Cheap, can reduce the production equipment investment in mines and reduce the proportion of fixed assets.

3. Wheel loader has a strong climbing ability and good maneuverability. It can perform loading operations on slope working surfaces that are not allowed by excavators, especially in new mine sites lacking electricity, which can speed up the development of mines. Construction and shortening the construction cycle.

4. Wheel loader's depreciation period is only 1/4 ~ 1/8 of the excavator. It can be replaced with new and more advanced equipment after 5 ~ 6 years of work, which is convenient for mine management and maintenance work and is conducive to equipment replacement.

5. Wheel loader is easier to operate than an excavator, so it can shorten the training time for the driver. At the same time, one loader only needs one driver to operate, which can save manpower, material and financial resources.

However, compared with the excavator, the wheel loader also has some disadvantages in production:

(1) Wheel loader has less excavation capacity than an excavator. When the blasting quality is not good and there are many large pieces, it's working efficiency will be significantly reduced; it is necessary to loosen the viscous materials before carrying out shovel operation and other auxiliary operations. .

(2) Compared with the XCMG Excavator, the working mechanism of the wheel loader is smaller in size; due to the limitation of safety conditions, it is not suitable to work on a high-explosive working face and the height of the stope generally does not exceed 12m.

(3) Wheel loader tires wear faster and have a shorter service life. In recent years, although measures have been added to protect the chain-link or use pad cushions to reduce tire wear, the tire life is only about 1500 hours, and tire costs still account for a large proportion of production equipment costs (about 40 % ~ 50%, even as high as 60%).
