Make preparations before construction
Correct construction organization design. The number and bearing capacity of dump trucks matched with excavator shall meet the requirements of excavator production capacity, and the capacity of dump trucks shall be an integral multiple of excavator bucket capacity. 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 respectively parked on the arc line that the excavator bucket can reach for unloading soil, so the bucket can turn forward to fill the car, and reverse to fill another car, so as to improve the loading efficiency.
Draw up the correct route of dump truck. In the construction organization, the driving route of dump truck shall be prepared in advance, and unnecessary ramps shall be removed. For each excavation road of the excavator, it is necessary to have an empty return road to avoid mutual interference when the dump truck enters and exits. Each operation road shall be kept in good condition to facilitate the operation of the dump truck.
Master the operation method of energy saving
Excavate in high efficiency area. The high efficiency area refers to the range between 45 degrees to 30 degrees from the vertical to the front of the jib. It is better to excavate in this range to fill the bucket. (the range varies according to the machinery)
No extra excavation. Continue to excavate after the bucket of excavator is full, which will cause fuel waste, just like causing overload such as hydraulic release, which will only consume fuel fearlessly, so please avoid.
Operate at the place with large excavation force. When the angle between the working machine and the cylinder is 90 degrees, the digging force is large, and the digging force mainly uses the digging force of the bucket.
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 work efficiency and reduce operation cost.
Avoid 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 rotation, so the operator should understand the data of the tail rotation radius, so that, during operation, a proper distance can be set aside to avoid scraping during rotation.
