长臂挖掘机

省时 省力 省财富

如今更是普遍的采用加长臂挖掘机来进行施工，因为使用它所具备的一些操作性能是很高的，但是在使用过程中一定要多多注意一些细节方面的问题，接下来为您介绍。

Nowadays, it is more common to use the extended boom excavator for construction, because some of its operating performance is very high. However, we must pay more attention to some details during the use process. Here is an introduction.

由于加长臂挖掘机比标准臂更长、更重、动作惯性更大，因此，操作时比标准臂要轻，各操纵过程应平稳，动作不宜过快、过猛，不宜紧急制动。挖斗容量按出厂标准配置使用，严禁更换使用大容量的挖斗。

Since the extended boom excavator is longer, heavier, and has greater inertia than the standard boom, it is lighter than the standard boom during operation. Each operation process should be stable, and the action should not be too fast, too violent, or emergency braking. The capacity of the bucket shall be configured and used according to the factory standard. It is strictly prohibited to replace the bucket with large capacity.

拥有加长臂挖掘机的挖掘机作业和行走场地应平整坚实，对松软地面应垫以枕木或垫板，沼泽地区应先作路基处理，或更换湿地专用履带板。使用前，履带式挖掘机的驱动轮应置于作业面的后方。平整作业场地时，不得用铲斗进行横扫或用铲斗对地面进行夯实。

The working and walking sites of excavators with extended boom excavators shall be flat and solid, and the soft ground shall be padded with sleepers or pads. In swampy areas, the subgrade shall be treated first, or the special track shoes for wetlands shall be replaced. Before use, the driving wheel of the crawler excavator shall be placed behind the working surface. When leveling the operation site, it is not allowed to sweep with a bucket or tamp the ground with a bucket.

加长臂挖掘机作业时，除松散土壤外，其大开挖高度和深度，不应超过机械本身性能规定。反铲作业时，履带距工作面边缘距离应大于2.0m。作业前检查项目应符合下列要求：照明、信号及报警装置等齐全有效；燃油、润滑油、液压油符合规定；各铰接部分连接可靠；液压系统无泄露现象。

During the operation of the extended boom excavator, except for the loose soil, its large excavation height and depth shall not exceed the performance requirements of the machinery itself. During backhoe operation, the distance between the track and the edge of the working face shall be greater than 2.0m. The inspection items before operation shall meet the following requirements: lighting, signal and alarm devices shall be complete and effective; Fuel oil, lubricating oil and hydraulic oil meet the requirements; All hinged parts are connected reliably; The hydraulic system has no leakage.

加长臂挖掘机作业时挖掘机应尽量保持水平位置，将行走机构制动住，并将履带揳紧。遇到较大的坚硬石块或障碍物时，应待清除后方可开挖，不得用铲斗破碎石块、冻土、或用单边斗齿硬啃。挖掘悬崖时，应采取防护措施。作业面不得留有伞沿及松动的大石块，当发现有塌方危险时，应立即处理或将挖掘机撤至安全地带。

During the operation of the extended boom excavator, the excavator shall keep the horizontal position as far as possible, brake the traveling mechanism, and tighten the track. When encountering large hard rocks or obstacles, the excavation can only be carried out after they are removed. It is not allowed to use a bucket to break rocks, frozen soil, or use a single bucket tooth to chew hard. Protective measures shall be taken when excavating cliffs. Umbrella edges and loose large rocks shall not be left on the working face. When there is a danger of collapse, it shall be handled immediately or the excavator shall be evacuated to a safe area.

加长臂挖掘机作业时应待机身稳定后再挖土，当铲斗未离开工作面时，不得作回转、行走等动作。回转制动时，应使用回转制动器，不得用转向离合器反转制动。颤抖升降不得过猛，下降时，不得碰撞车架或履带。动臂、斗杆在抬高及回转时，不得碰到洞壁、沟槽侧面及其他物体。

During the operation of the extended boom excavator, the body shall be stabilized before digging. When the bucket does not leave the working face, it is not allowed to swing or walk. During slewing braking, the slewing brake shall be used, and the steering clutch shall not be used for reverse braking. The trembling lifting shall not be too violent, and the frame or track shall not be collided when descending. The boom and stick shall not touch the tunnel wall, groove side and other objects during lifting and turning.
