Make preparations before construction
Correct construction arrangement design. The quantity and bearing capacity of the dump truck matched with the excavator shall meet the requirements of the production capacity of the excavator, and the capacity of the dump truck shall be an integral multiple of the excavation bucket capacity of the excavator. At the same time, try to use the double loading method to make the excavator full of one, and then load the next. Because the two dump trucks are separated and parked on the arc line where the excavator bucket can unload soil. In this way, the bucket can be turned forward to be full and the car can be turned back to be full of another car, and then the loading power can be increased.
Draw up the correct route of dump truck. In the construction arrangement, the driving route of dump truck shall be prepared in advance, and unnecessary ramps shall be removed. For each roadheader of the excavator, it is necessary to have an empty return road to avoid mutual disturbance when the dump truck enters and exits. Each transfer road shall adhere to excellence to facilitate the operation of the dump truck.
Grasp the operation method of energy saving
Excavate in high power area. The high-power area refers to the scale of the forearm moving 45 degrees to 30 degrees forward from the straight state. It is better to excavate in this scale to fill the bucket. (the scale varies according to the machinery)
No unnecessary excavation. After the hopper of the excavator is full, continuous excavation will result in fuel waste. It seems to cause overload such as hydraulic release, which will only consume fuel fearlessly, so please prevent.
Operate in the direction of large excavation force. When the angle between the working machine and the cylinder is 90 degrees, the excavation force is larger, and the excavation force is mainly the excavation force of the bucket.
Timely protection and maintenance
Bucket reinforcement. When the excavator bucket is used, the saw tooth is the device at the end of the machine, which is particularly vulnerable to damage. If conditions permit, it is recommended to reinforce the bucket before using the excavator, so as to ensure that the bucket is more durable, effectively improve the operation power and reduce the operation cost.
Prevent scraping at the end of the bucket. Before digging, the working environment shall be cleaned and all obstacles higher than the track shoes within the rotating radius shall be cleared. Under normal circumstances, the scraping at the tail of the excavator bucket is mostly caused by the time of rotation, so the operator should know about the data of the tail rotation radius, so that the appropriate interval can be set aside during the operation to prevent the scraping at the time of rotation.
