加长臂长期在恶劣的环境下作业，保养加长臂可以减少加长臂故障，延长加长臂使用寿命，更好提高工作效率，使加长臂达到***的状态。

The extended arm operates in harsh environments for a long time. Maintaining the extended arm can reduce its malfunctions, extend its service life, improve work efficiency, and achieve optimal performance.

加长大小臂每天少打两次黄油。在泥水中作业时，若工作装置连接销轴浸在水中，则每次完工后都要清洗干净再加黄油。每次作业前都要检查工作装置连接部位是否加满黄油。每次加黄油后，操作动臂斗杆和铲斗数次，然后再加黄油，直到将旧黄油挤出为止。

Apply butter at least twice a day to lengthen the upper and lower arms. When working in muddy water, if the connecting pin of the work device is immersed in water, it should be cleaned thoroughly and then buttered after each completion. Before each assignment, check whether the connection part of the work device is filled with butter. After adding butter each time, operate the boom and bucket several times, then add butter again until the old butter is squeezed out.

在海滨地区或腐蚀地区作业，操作后要彻底清洗整个机器，以除去盐分，必要时在需要的地方加黄油或机油，以避免锈蚀。在寒冷的冬天作业，必须将液压缸的活塞杆回到液压缸筒内，避免泥土和水粘在活塞杆上，损坏液压缸密封圈。

When working in coastal or corrosive areas, the entire machine should be thoroughly cleaned after operation to remove salt. If necessary, butter or engine oil should be added where needed to avoid rusting. In cold winter work, it is necessary to return the piston rod of the hydraulic cylinder to the hydraulic cylinder barrel to avoid soil and water sticking to the piston rod, which may damage the sealing ring of the hydraulic cylinder.

长臂挖掘机的施工注意事项

Construction precautions for long arm excavators

挖掘机回转时，必须离地面0.5米。

When the excavator rotates, it must be 0.5 meters above the ground.

铲斗插入工作目标时，严禁大力敲打，也不能行走和旋转。

When inserting the bucket into the work target, it is strictly prohibited to strike vigorously, and walking and rotating are also prohibited.

使液压缸活塞杆运动不能伸到行程终点，应保留一小段距离。

If the movement of the hydraulic cylinder piston rod cannot reach the end of the stroke, a small safe distance should be kept.

不能用加长臂吊过重的物品。

Do not use extended arms to lift heavy objects.

在岩质地面操作时，不能直接插入，要利用其他方法破碎后再挖掘。

When operating on rocky ground, direct insertion is not allowed, and other methods should be used to break it before excavation.

使用合适于挖掘能力的铲斗，不能使用超过或负载的铲斗，直接影响挖掘机和加长臂的使用命。

Use a bucket that is suitable for excavation capacity, and do not use a bucket that exceeds or is overloaded, as it directly affects the service life of the excavator and extended arm.

挖掘机大小臂改装前提是要考虑动力，液压以及配重平衡几个方面。。

The prerequisite for modifying the excavator's large and small arms is to consider several aspects such as power, hydraulic pressure, and counterweight balance..
