        A little knowledge of excavators

             Before operating the excavator, first confirm the surrounding situation. When the excavator is walking, the working device should be retracted as far as possible and close to the center of the fuselage to maintain stability. Avoid obstacles such as 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 on the obstacle. So what is the specific operation method of the excavator? Let's take a look!

        1. Excavator operation technology

            Check your surroundings first. When rotating, pay attention to the surrounding obstacles and terrain, safe operation; During operation, confirm the direction of the front and back of the track to avoid tipping or collision; Try not to turn the final drive towards the direction of excavation, otherwise it will easily damage the walking motor or hose; During operation, the left and right track are fully in contact with the ground to improve the dynamic stability of the whole machine.

        2.slope leveling operation

            Place the machine flat on the ground during the plane trimming process to prevent the machine from shaking. It is very important to grasp the coordination of the movement of the boom and the bucket rod and control their speed for the plane dressing.

        3. Loading operation

             The body should be in a horizontal stable position, otherwise it is difficult to accurately control rotary unloading, thus prolonging the working cycle time; Keep proper distance between the body and the truck to prevent the rear of the body from colliding with the truck during the 180 degree turn; As far as possible, left-handed installation, wide field of view, high efficiency. At the same time, correctly grasp the rotation Angle, reduce the rotation time; The position of the truck is lower than that of the excavator to shorten the lifting time of the boom and have a good line of sight; Load the sand first, and then enlarge the stone, you can reduce the impact on the tree trunk.

        4.effective mining methods

              When the bucket cylinder and the connecting rod, the bucket cylinder and the bucket rod are at a 90 degree Angle, the digging force is maximum. When the bucket teeth are at a 30 degree Angle with the ground, the digging force is the best, that is, the cutting resistance is the least. When digging with a bucket pole, make sure the Angle range of the bucket pole is between 45 degrees and 30 degrees back. The use of both boom and bucket can increase digging efficiency.

        5. Dig rocks

             Digging rocks with buckets can cause great damage to the machine and should be avoided as much as possible. When it is necessary to excavate, the position of the fuselage should be adjusted according to the direction of the fracture of the rock, so that the bucket can be smoothly shoveled into the excavation; Insert the bucket teeth into the rock crevices, and use the digging force of the bucket rod and bucket to dig (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 carrying out the lifting operation, confirm the surrounding conditions of the lifting site, use high-strength lifting hooks and steel cables, and use special lifting equipment as much as possible; The operation mode should be micro-operation mode, and the action should be slow and balanced; The sling is the right length. If it is too long, the suspended object swings greatly and is difficult to control accurately; Adjust the bucket position correctly to prevent the wire rope from slipping; The construction personnel should try not to get close to the lifting objects to avoid the danger caused by improper operation.

        7. Stable operation method

             In the operation process, the stability of the machine can not only improve the work efficiency, extend 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 track on the ground is always greater than the pitch of the track, so the stability of the forward work is good, and the lateral operation is avoided as far as possible. Keep the excavator close to the dig site to improve stability; If the digging point is far away from the machine, the operation will be unstable due to the advance of the center of gravity; 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 dig point and the center of the fuselage to make the operation balanced and efficient.

        8. Work in soft soil or water

              When working in soft soil areas, understand the degree of soil porosity, pay attention to limit the bucket excavation range, to prevent landslides, collapse, deep sinking of the vehicle body and other accidents.
