In modern construction, mining and earthwork, loaders are undoubtedly indispensable tools. Their powerful loading and handling capabilities greatly improve engineering efficiency. However, facing the dazzling array of loader models on the market, how to choose a suitable loader has become a difficult problem for many project managers. This article will comprehensively analyze the classification, use and selection principles of loaders to help you easily grasp the key points of loader selection.

1. Classification and use of loaders

Loaders can be divided into many types according to engine power, transmission form, walking system structure and loading and unloading methods. First, according to engine power, they can be divided into small (less than 74kw), medium (74~147kw), large (147~515kw) and extra-large (greater than 515kw) loaders. Loaders of different powers are suitable for engineering projects of different sizes. Secondly, according to the transmission form, it can be divided into hydraulic-mechanical transmission, hydraulic transmission and electric transmission. Among them, hydraulic-mechanical transmission is widely used in medium and large loaders due to its advantages such as small impact vibration and long life of transmission parts.

In terms of walking structure, tire loaders and crawler loaders have their own characteristics. Tire loaders are light, fast, and flexible, while crawler loaders have the advantages of low ground pressure and good passability. Finally, according to the loading and unloading method, it can be divided into front-unloading, rotary and rear-unloading loaders. Among them, front-unloading loaders are popular because of their simple structure and reliable operation.

2. Principles of loader selection

When purchasing a loader, first of all, you should choose and determine it according to the operating occasion and purpose. For example, if you are working in a quarry or soft base, you should choose a tire loader with anti-skid chains. Secondly, you should choose the appropriate engine type according to the climatic conditions of the project location. For example, plateau diesel engines should be used in plateau areas. The choice of transmission type is also the key to selection. Hydraulic-mechanical transmission is the first choice because of its superior performance.

In addition, when selecting a loader, its braking performance must be fully considered. There are three types of brakes: shoe type, caliper disc type and wet multi-plate type. Among them, the air-over-oil brake system is highly praised for its stable braking effect and high safety. At the same time, the use of a dual-circuit brake system can further improve driving safety.

Summary

Through the introduction of this article, I believe you have a comprehensive understanding of the classification, use and selection principles of loaders. When purchasing a loader, please be sure to make a comprehensive consideration based on the actual needs of the project, the operating environment and climatic conditions to ensure that you choose the most suitable loader model. At the same time, pay attention to the braking performance and safety configuration of the loader to ensure the safety and smooth progress of the engineering operation.
