Tunnel loader can be used to shovel, transport, unload and level bulk materials, and also to excavate hard rock and soil lightly. Therefore, it is widely used in construction, highway, railway, hydropower, port, mine and national defense projects. It plays an important role in accelerating construction speed, reducing labor intensity, improving project quality and reducing project cost, So the loader has a rapid development in both varieties and production at home and abroad, and has become one of the main varieties of construction machinery.

隧道装载机工作装置是装载机的核心部件之一，尽管不同类型的装载机间存在些许结构上的差异，但常设主要由铲斗、动臂、摇臂—连杆(或托架)及液压系统等组成。它的作业过程是由液压操纵装置来完成的。它是用来克服被切削物料的阻力，并完成插入料堆，铲取物料，提升并卸除物料等一系列工作的装置。

The working device of the tunnel loader is one of the core components of the loader. Although there are some structural differences between different types of loaders, it is mainly composed of bucket, boom, rocker link (or bracket) and hydraulic system. Its operation process is completed by the hydraulic control device. It is used to overcome the resistance of the material to be cut, and complete a series of work such as inserting the material pile, shoveling the material, lifting and unloading the material.

现有的装载机在相应号召的情况下，对机械结构做了一系列的精进处理，包括配置安装水过滤系统排放问题，选装化学净化装置，在恶劣环境下也可使用。此类机型能帮助实现减排的目标，质量更可靠，使用更经济，操作维修更方便，、整机性能很大提高，整机振动和噪声明显降低，整机具有很高的性价比。

The existing loaders in the corresponding environmental protection and energy saving call for a series of advanced treatment of mechanical structure, including the installation of water filtration system to solve the emission problem, optional chemical purification device, can also be used in harsh environment. This kind of machine can help to achieve the goal of energy saving and emission reduction, with more reliable quality, more economical use, more convenient operation and maintenance, energy saving, greatly improved performance of the whole machine, significantly reduced vibration and noise of the whole machine, and high cost performance of the whole machine.

不断创新的装载机产品产品适用于各种建筑工程工地、道路施工工程、矿井低作业场地，农田水利施工工程、环卫垃圾、砂石厂、粮仓、粮场、米厂、面粉厂、食品厂，用于砂石、煤炭、粮食、饲料、工业原料等散装物料的铲运上料及装载。

The innovative loader products are suitable for all kinds of construction sites, road construction projects, mine low operation sites, farmland water conservancy construction projects, environmental sanitation waste, gravel plants, granaries, grain farms, rice factories, flour factories, food factories, and are used for shoveling and loading of bulk materials such as gravel, coal, grain, feed, industrial raw materials, etc.
