First, what are the types of excavation methods of Ten field excavators
Excavation method: There are two methods: forward palm excavation and lateral palm excavation, (the working space of the excavator is called the palm surface)
Digging forward: The soil in front of a large excavator excavator is called digging forward. Suitable for foundation pit excavation. The contour size of the palm is determined by the working performance of the excavator and the mode of transportation, and the widest working face should be used as far as possible to make the car easy to reverse and move soil.
Lateral palm excavation: The soil on the side of the direction of the excavator is called lateral palm excavation. Suitable for excavating the soil of the material yard, mound and channel. The characteristic is that the truck is parked on the side of the excavator, parallel to the line of the excavator. The advantage is that the rotation Angle of the excavator is small when unloading, which saves the time of reversing and turning of the car, and can improve production efficiency.
Second, energy-saving excavator safety operation rules
1. After the engine starts, no one is allowed to stand in the bucket, arm rod, track and hangar.
2, the working position must be flat and stable. Before work, the track should be braked, the tire excavator should top the legs, the direction of the body should be consistent with the extension direction of the digging face, and the shovel should not be too deep and the bucket should not be too strong.
3. When excavating earthwork with stones on a high and steep working surface, the larger stones and debris should be removed. If the soil is dug into a suspended state and cannot collapse naturally, manual treatment is required, and it is strictly prohibited to use a shovel to smash down the suspended earth.
4. It is strictly prohibited to cross the bucket from the top of the cab of the earth truck. When unloading the soil to the earth truck, the height of the bucket should be reduced to prevent partial load or damage to the vehicle.
