1. Excavation operation excavation operation is the operation of stopping or advancing the vehicle, inserting the bucket into the sediment such as sand, soil and rock, loading and shoveling. The excavation operation is divided into shovel operation and excavation operation. When excavating, make both sides of the bucket bear the load evenly, not only one side. Make the loader straight to the front, instead of making the front and rear frames have an angle.

２．装载作业（搬运工程方式）将沙土、岩石、矿石等物，倒入卡车、货车、集装箱的作业，可选用高 效率的方法进行。要按照现场的状况，先定搬运工程方式：主要有装载机和运输车配套的工程方式和仅用轮胎式装载机的装载搬运工程方式。装载机、运输车配套工程方式如图所示有４种作业法。按照作业现场的状况，可以选定循环时间（一次装载时间）短的作业方法—装载搬运工程方式。以上方式是用轮胎装载机连续进行铲进、搬运、倒入的。通常适合于３０～１００ｍ程度的搬运距离。

2. Loading operation (handling engineering method) the operation of pouring sand, rock, ore and other objects into trucks, trucks and containers can be carried out by efficient methods. According to the site conditions, the handling engineering mode shall be determined first: mainly including the supporting engineering mode of loader and transport vehicle and the loading and handling engineering mode of tire loader only. The supporting engineering modes of loaders and transport vehicles are shown in the figure. There are four operation methods. According to the conditions of the operation site, the operation method with short cycle time (one-time loading time) - loading and handling engineering method can be selected. The above methods are continuously shoveled, transported and poured with a tire loader. It is generally suitable for handling distance of 30 ~ 100m.

３．卸载作业往汽车或货场倾卸物料时，应将动臂提升到使铲斗碰不到车箱和料堆为止，前推斗操纵杆仗铲斗前倾卸载，通过斗操纵杆的控制可全部卸载或卸去部分，卸载时要求动作缓和以减轻物料对载重汽车的冲击。当物料粘积铲斗时，可来回搬动转斗操纵杆，使铲斗振动脱落物料。

3. During the unloading operation, when dumping materials to the truck or freight yard, the boom shall be lifted so that the bucket can not touch the truck body and material pile. The front push bucket control lever tilts forward with the bucket for unloading. All or part can be unloaded through the control of the bucket control lever. During unloading, the action shall be gentle to reduce the impact of materials on the truck. When materials stick to the bucket, move the rotary bucket control lever back and forth to make the bucket vibrate and fall off materials.

４．整地作业利用铲斗前尖和底面所成角度，可以进行撒土、平整、打基础等整地作业。整地作业务必使车辆后退而进行。

4. The angle between the front tip and the bottom of the bucket can be used for soil spreading, leveling, foundation laying and other ground preparation operations. The land preparation business must make the vehicle back.

５．填平作业如果将铲斗做为推土刮板用时，可以进行填平作业。此时铲斗内满载沙土，使其对地面保持水平状态，进行作业。

5. If the bucket is used as a bulldozer scraper, the filling operation can be carried out. At this time, the bucket is full of sand and soil to keep it horizontal to the ground for operation.
