Tunnel loader has the advantages of fast operation speed, good mobility and light operation, so it develops rapidly and becomes the main machine in earthwork construction. Loader as a commonly used machinery, if you do not pay attention to maintenance at ordinary times, it will cost more money.

隧道装载机日常维护保养需要注意八大点，一起来看看吧。

The daily maintenance of tunnel loader needs to pay attention to eight points. Let's have a look.

1、检查发动机机油油量、水箱水量、变速器和柴油箱以及工作油箱油量。2、检查轮胎气压和外形。

1. Check the oil quantity of engine, water quantity of water tank, oil quantity of transmission, diesel tank and working oil tank. 2. Check the tire pressure and profile.

3、检查操纵机构、讯号设备是否完好。

3. Check whether the operating mechanism and signal equipment are in good condition.

4、发动机发动后有无异常响声、各仪表工作是否正常。

4. Whether there is abnormal noise after the engine is started and whether the instruments work normally.

5、各部是否有漏油、漏水、漏气。

5. Whether there is oil leakage, water leakage and air leakage in each department.

6、变速器、变矩器、前后桥等有无过热现象。

6. Check whether the transmission, torque converter, front and rear axles are overheated.

7、各部紧固件有无松动丢失现象。

7. Whether the fasteners are loose or missing.

8、冬季作业完毕注意发动机放水。

8. Pay attention to drain the engine after winter operation.

隧道装载机的选用原则：

Selection principle of tunnel loader:

1、机型的选择：主要依据作业场合和用途进行选择和确定。一般在采石场和软基地进行作业，多选用履带式装载机;

1. Selection of machine type: it is mainly selected and determined according to the operation situation and purpose. Generally, crawler loaders are used in quarries and soft bases;

2、动力的选择：一般多采用工程机械用柴油发动机，在特殊地域作业，如海拔高于3000m的地方，应采用特殊的高原型柴油发动机;

2. Power selection: generally, the diesel engine for construction machinery is used, and the special plateau diesel engine should be used when working in special areas, such as places with altitude higher than 3000m;

3、传动型式的选择：一般选用液力—机械传动。其中关键部件是变矩器形式的选择。生产的装载机多选用双涡轮、单级两相液力度矩器。

3. Selection of transmission type: hydraulic mechanical transmission is generally selected. The key component is the selection of torque converter. The loaders made in China mostly use double turbine and single-stage two-phase liquid torque converter.

4、在选用装载机时，还要充分考虑装载机的制动性能，包括多个在制动、停车制动和紧急制动三种。制动器有蹄式、钳盘式和湿式多片式三种。制动器的驱动机构一般采用加力装置，其动力源有压缩空气，气顶油和液压式三种。常用的是气顶油制动系统，一般采用双回路制动系统，以提高行驶的性。

4. When selecting the loader, the braking performance of the loader should be fully considered, including multiple in braking, parking braking and emergency braking. There are three types of brakes: shoe type, caliper disc type and wet multi disc type. The driving mechanism of the brake generally adopts the afterburner, and its power sources are compressed air, air top oil and hydraulic. Commonly used is the air top oil braking system, generally uses the double circuit braking system, in order to improve the driving safety.
