Small Tips for Excavator

Before operating the excavator, first check the surrounding conditions. When the excavator is walking, the working device should be retracted as far as possible, close to the center of the fuselage to maintain stability. Avoid driving over obstacles such as tree stumps and rocks as much as possible to prevent track deformation. If you need to drive over an obstacle, make sure the center of the track is over the obstacle. So what is the specific operation method of the excavator? Let's take a look together!

1. Excavator operation technology

Check your surroundings first. When rotating, pay attention to the surrounding obstacles and terrain, and work safely; during operation, confirm the front and rear directions of the track to avoid tipping or collision; try not to turn the final drive towards the excavation direction, otherwise it is easy to damage the traveling motor or hose; during the operation, Ensure that the left and right tracks are in full contact with the ground and improve the dynamic stability of the whole machine.

2. Slope leveling operation

During the leveling process, lay the machine flat on the ground to prevent the machine from shaking. Mastering the coordination of the movements of the boom and stick, and controlling their speed, is critical for surface trimming.

3. Loading operation

The body should be in a horizontal and stable position, otherwise it will be difficult to precisely control the rotation and unloading, thus prolonging the working cycle time; the body and the truck should keep an appropriate distance to prevent the rear of the body from colliding with the truck when turning 180 degrees; the left-handed installation should be adopted as much as possible, with a wide field of vision and easy operation. efficient. At the same time, correctly grasp the rotation angle to reduce the rotation time; the position of the truck is lower than the excavator, so as to shorten the lifting time of the boom and have a good line of sight; load the sand and gravel first, and then enlarge the stone, which can reduce the impact on the trunk.

4. Effective mining methods

Digging force is greatest when the bucket cylinder is at a 90-degree angle to the connecting rod, stick cylinder and stick. When the bucket teeth are at an angle of 30 degrees to the ground, the digging force is the best, that is, the soil cutting resistance is the least; when digging with the stick, make sure that the angle range of the stick is between 45 degrees in the front and 30 degrees in the back. Using the boom and bucket together can improve digging efficiency.

5. Dig rocks

Digging rocks with a bucket can cause significant damage to the machine and should be avoided as much as possible. When digging is required, the position of the fuselage should be adjusted according to the direction of the crack of the rock, so that the bucket can be shoveled in smoothly for excavation; the bucket teeth are inserted into the cracks of the rock, and the excavation force of the stick and bucket is used to excavate (pay attention to the sliding of the bucket teeth); When lifting with a hydraulic excavator, the unbroken rock should be broken first, and then excavated with a bucket.

6. Lifting operation

When the hydraulic excavator is hoisting, confirm the surrounding conditions of the hoisting site, use high-strength hooks and wire ropes, and use special hoisting equipment as much as possible; the operation method should be micro-operation, and the movements should be slow and balanced; the length of the sling is appropriate. If it is too long, the suspended object will swing greatly, which is difficult to control accurately; adjust the position of the bucket correctly to prevent the wire rope from slipping; the construction personnel should try not to get close to the lifting object to avoid danger caused by improper operation.

7. Stable operation method

During operation, the stability of the machine can not only improve the work efficiency and prolong the service life of the machine, but also ensure safe operation (put the machine on a flat ground); the stability of the rear drive sprocket is better than that of the front drive sprocket , which can prevent the main reducer from being impacted by external forces. The wheelbase of the crawler on the ground is always greater than the crawler pitch, so the stability of the forward work is good, try to avoid lateral operation; keep the excavator close to the excavation point to improve stability; if the excavation point is far away from the machine, the center of gravity moves forward , the operation will be unstable; lateral excavation is more unstable than forward excavation. If the dig point is far from the center of the fuselage, the machine will be more unstable. Therefore, an appropriate distance should be maintained between the excavation point and the center of the fuselage for a balanced and efficient operation.

8. Work in soft soil or water

When working in soft soil areas, understand the degree of soil porosity, and pay attention to limiting the excavation range of the bucket to prevent accidents such as landslides, collapses, and deep sinking of the vehicle body.
