The underground loader is mainly used to shovel soil, sand, lime, coal and other bulk materials, as well as light shovel excavation of ore and hard soil. Because the mining loader has the advantages of fast operation speed, good mobility and light operation, it has developed rapidly and become the main machinery in earthwork construction.

井下开采空间狭小、通风条件差，井下装载机以保障工作效率为前提，在机械结构设计上采用双翻斗缸设计，活动灵活，其他相关工作装置更是经计算机优化设计，使其结构更合理，具有强劲的铲掘力和较短的作业循环时间，工作效率更高；优化散热器结构，采用五叶片不等角风扇，系统采用铝制散热器，增加了散热面积，优化整个系统的进出风道设低发动机水温和液压系统的油温，热平衡温度更低，提高了整机效率，可以适应更高井下的特殊工作环境温度；基于井下环境问题考量。

The underground mining space is narrow and the ventilation conditions are poor. On the premise of ensuring the working efficiency, the underground loader adopts the double tipper cylinder design in the mechanical structure design, which is flexible. Other relevant working devices are optimized by computer, so that their structure is more reasonable, with strong digging force, short operation cycle time and higher working efficiency; Optimize the radiator structure, adopt five blade unequal angle fan, and the system adopts aluminum radiator to increase the heat dissipation area. Optimize the inlet and outlet air duct of the whole system, set low engine water temperature and oil temperature of hydraulic system, lower heat balance temperature, improve the efficiency of the whole machine, and can adapt to higher special working environment temperature under the well; Based on the consideration of downhole environmental problems.

在设计上还对排放装置做了一系列结构改进与创新，发动机排出的废气通过两级过滤，保证在空气流通不畅的空间内工人作业的健康问题。巷道专用装载机，采用大功率四缸柴油机，功率储备大，动力强劲。整机外观大方、稳重。超低车身设计，狭窄低矮巷道作业难题。液压油路加装3级过滤，保证液压系统清洁、通畅、可靠，延长各液压元件的使用寿命。后置排烟过滤系统，保证了巷道作业场所的空气清洁。

A series of structural improvements and innovations have also been made in the design of the emission device. The exhaust gas discharged by the engine is filtered through two stages to ensure the health of workers in the space with poor air circulation. The special loader for roadway adopts high-power four cylinder diesel engine with large power reserve and strong power. The appearance of the whole machine is generous and stable. The ultra-low body design solves the difficult problem of narrow and low roadway operation. The hydraulic oil circuit is equipped with three-stage filtration to ensure that the hydraulic system is clean, unobstructed and reliable, and prolong the service life of each hydraulic element. The rear smoke exhaust filter system ensures the air cleanliness of the roadway workplace.

除却上述基本性能设计外，考虑到装载作业的稳定性问题，在稳定性保障设置上有气顶油助力制动系统，制动效果更灵敏，行驶更稳定；采用负荷传感、优先转向的分合流液压系统、动力换挡变速，整机操纵轻便灵活、动作平稳可靠；采用低压宽基工程机械轮胎，后桥摆动，具有良好的越野和通过性能，适应崎岖不平的路面上的稳定行驶和作业。

In addition to the above basic performance design, considering the stability of loading operation, there is an air top oil assisted braking system in the stability guarantee setting, which makes the braking effect more sensitive and driving more stable; The split and merge hydraulic system with load sensing and priority steering and power shift speed change are adopted. The whole machine has light and flexible operation and stable and reliable action; The low-pressure wide base construction machinery tire is adopted, and the rear axle swings. It has good off-road and trafficability, and is suitable for stable driving and operation on rugged roads.
