The Use Of Various Excavator Operations Skills

1. Excavator operation technology:

The first thing to do is to check your surroundings. When rotating operation, the surrounding obstacles, terrain to do well, safe operation; During operation, it is necessary to confirm the front and back direction of the track to avoid tipping over or impact; Try not to put the final drive facing the direction of excavation, otherwise it is easy to damage the walking motor or hose; During operation, the left and right track should be fully contacted with the ground to improve the dynamic stability of the whole machine.

2. Effective excavation method of wheeled excavator:

When the bucket cylinder and connecting rod, bucket rod cylinder and bucket rod into 90 degrees between each other, the mining force is large; When the bucket teeth and the ground maintain a 30 degree Angle, the digging force, that is, the resistance to cutting soil is small; When digging with a bucket pole, the Angle range of the bucket pole should be ensured between 45 degrees in the front and 30 degrees in the back. The use of boom and bucket at the same time can improve the excavation efficiency.

3. Dig rocks:

The use of bucket excavation rock will cause great damage to the machine, should be avoided; When digging, the position of the body should be adjusted according to the direction of the crack of the rock, so that the bucket can be smoothly shoveled into the excavation; The bucket teeth into the rock cracks, with the bucket rod and bucket excavation force excavation (should pay attention to the bucket teeth slip); Rocks that have not been crushed should be broken before excavating with a bucket.

4. Slope leveling operation:

When plane dressing, the machine should be placed flat on the ground to prevent body shaking. It is important to grasp the coordination of the movement of the boom and the bucket rod and control the speed of the two for plane dressing.

5. Loading operation:

The body should be in a stable horizontal position, otherwise it is difficult to control rotary unloading accurately, thus prolonging the working cycle time; The body should keep a proper distance from the truck to prevent the tail of the body from touching the truck when doing 180 degrees of rotation; As far as possible on the left rotation, so that the field of vision, high efficiency, at the same time to grasp the correct rotation Angle, in order to reduce the time used for rotation; The position of the truck is lower than that of the excavator to shorten the lifting time of the boom, and the line of sight is good; First load sand, gravel, and then place large stones, which can reduce the impact on the car.
