省时 省力 省财富

挖机操作手应谨记这些注意事项，从而更好的提高工作效率，更好的避免施工中出现的问题和设备故障。特别是对新手而言，好的操作方法，更是宝贵的经验总结。

Excavator operators should keep these precautions in mind to better improve work efficiency and avoid problems and equipment failures during construction. Especially for beginners, good operating methods are valuable experience summaries.

1、操作技术

1. Operational techniques

开始启动设备之前要确认周围工作环境。

Before starting the device, confirm the surrounding working environment.

回转作业时，对周围障碍物、地形要做到心中有数，安全操作；

When rotating, it is necessary to have a clear understanding of the surrounding obstacles and terrain and operate safely;

作业时，要确认履带的前后方向，避免造成倾翻或撞击。

When working, it is necessary to confirm the front and rear directions of the track to avoid tipping or impact.

尽量不要把终传动面对着挖掘方向，容易损伤行走马达及软管；

Try not to face the final drive face towards the excavation direction, as it may damage the walking motor and hose;

作业时，要确保履带与地面完全接触，保持机身的稳定性。

During operation, it is necessary to ensure that the track is in complete contact with the ground and maintain the stability of the machine body.

2、有效挖掘方法

2. Effective mining methods

当铲斗缸和连杆、斗杆缸和斗杆之间垂直时，挖掘力度；

When the bucket cylinder and connecting rod, as well as the stick cylinder and stick are perpendicular, the excavation force is the highest;

铲斗斗齿和地面保持30度角时，挖掘力，并且切土阻力更小；

When the bucket teeth maintain a 30 degree angle with the ground, the excavation force is the best and the soil cutting resistance is the smallest;

用斗杆挖掘时，应该保证斗杆角度范围在前面45度角到后面30度之间。

When excavating with a stick, it should be ensured that the angle range of the stick is between the front 45 degrees and the back 30 degrees.

同时使用动臂和铲斗，从而提高挖掘效率。

Simultaneously use the boom and bucket to improve excavation efficiency.

3、装载作业

3. Loading job

挖机机身应处于水平稳定的位置，否则回转卸载将难以准确控制，从而延长作业时间；

The excavator body should be in a horizontal and stable position, otherwise it will be difficult to accurately control the rotation and unloading, thereby extending the operation time;

挖机机身与卡车要保持适当的距离，防止在做180度回转时机身的尾部与卡车相碰；

Maintain an appropriate distance between the excavator body and the truck to prevent the rear of the body from colliding with the truck during a 180 degree rotation;

尽量进行左回转装卸，这样做保证了开阔的视野、也提高了工作效率，同时要掌握好旋转的角度，以减少回转时间；

Try to carry out left turning loading and unloading as much as possible, which ensures a wide view and improves work efficiency. At the same time, it is necessary to grasp the rotation angle to reduce turning time;

卡车位置应该比挖掘机位置低，以缩短动臂提升时间，而且更能保证视线良好；

The truck position should be lower than the excavator position to shorten the boom lifting time and ensure good visibility;

应先装砂土、碎石，再放置大石块，这样可以减少对车厢的撞击。

Sand and gravel should be loaded first, and then large stones should be placed to reduce impact on the carriage.

4、挖掘岩石

4. Excavation of Rock

使用铲斗挖掘岩石会对设备造成较大破坏，应该尽量避免；

Excavating rocks with a bucket can cause significant damage to the equipment and should be avoided as much as possible;

必须挖掘时，应该根据岩石的裂纹方向来调整机体的位置，使铲斗能够顺利铲入，进行挖掘；

When excavation is necessary, the position of the machine body should be adjusted according to the direction of the rock crack, so that the bucket can smoothly enter and excavate;

把斗齿插入岩石裂缝中，用斗杆和铲斗的挖掘力进行挖掘；

Insert the bucket teeth into the rock cracks and excavate with the digging force of the bucket rod and bucket;

未被碎裂的岩石，应先破碎后再使用铲斗挖掘。

Rock that has not been broken should be broken first before excavation with a bucket.

5、吊装作业

5. Lifting operation

用液压挖掘机进行吊装操作，应确认吊装现场周围状况，使用高强度的吊勾和钢丝绳，吊装时要尽量使用专用的吊装装置；

When using a hydraulic excavator for lifting operations, the surrounding conditions of the lifting site should be confirmed, high-strength lifting hooks and steel wire ropes should be used, and special lifting devices should be used as much as possible during lifting;

作业方式应选择微操作模式，动作要缓慢平衡；

The operation mode should be micro operation mode, and the actions should be slow and balanced;

吊绳长短适当，吊绳过长会使吊物摆动较大而难以精确控制；要正确调整铲斗位置，以防止钢线绳滑脱；

The length of the lifting rope is appropriate, and if the lifting rope is too long, it will cause the suspended object to swing more and be difficult to accurately control; Correctly adjust the position of the bucket to prevent the steel wire rope from slipping;

施工人员尽量不要靠近吊装物，以防止因操作不当而发生危险。

Construction personnel should try not to approach the lifting object as much as possible to prevent danger caused by improper operation.

6、坡面平整作业

6. Slope leveling operation

进行平面修整时应将机器停放在水平面上，保持机身的稳定性，把握动臂与斗杆的动作协调性，控制两者的速度对于平面修整至关重要。

When performing surface finishing, it is crucial to park the machine on a horizontal surface, maintain the stability of the body, grasp the coordination of the movements of the boom and bucket, and control the speed of both for surface finishing.
