Key points: subjectivity and objectivity: factors affecting excavator productivity: 1) conduct construction organization design correctly. The number and carrying capacity of the dump truck with the excavator should meet the requirements of the excavator's production capacity, and the capacity of the dump truck should be the integer times of the excavator bucket capacity.
Improving the productivity of excavators can be carried out in the following aspects:
1) correctly carry out the construction organization design. The number and carrying capacity of the dump truck with the excavator should meet the requirements of the excavator's production capacity, and the capacity of the dump truck should be the integer times of the excavator bucket capacity. At the same time, we try to use the double loading method to fill the excavator with one, and then put it next. As two dump trucks are parked in the arc line of excavator bucket, the bucket is full and the reverse can be filled with another car, thus improving the loading efficiency.
2) in the construction organization, the traveling route of the dump truck should be worked out in advance to remove unnecessary ramps. For the excavators, there must be an empty return road to avoid interference between the dump trucks when they enter and exit. The operating roads should be kept good and good for the operation of dump trucks.
3) excavator drivers should have skilled operation techniques.
