Excavator operating skills

1, operation technology

First to confirm the situation around. The rotation, the obstacles around the terrain, to be aware of safety operation; operation of Anhui Dejia excavator, to confirm the fore-and-aft direction of the track, to avoid tipping or impact; try not to face the final drive mining direction, otherwise easy to damage the walking motor or hose; during the operation, to ensure the right track and ground completely contact, improve the dynamic stability of the complete machine.

2, effective mining method

When the bucket cylinder and the connecting rod, between the cylinder and the bucket rod bucket rod are 90 degrees, the maximum digging force; bucket teeth and ground at a 30 degree angle, the best cutting soil digging force minimum resistance; with stick mining, should ensure that the bucket rod angle in the range from behind the front angle of 45 to 30 between. At the same time, the use of boom and bucket, can improve the efficiency of mining.

3, mining rock

Use the bucket digging rock will cause great damage to the machine, should be avoided; we must dig, should adjust the direction of the rock body according to the crack position, the bucket can smoothly shovel digging; the bucket tooth, insert a crack in the rock, with a stick and bucket digging force mining (slip should be mindful of the bucket teeth); is not the rocks, should be broken and then use the bucket digging.

4, slope smooth operation

When the plane repair, the machine should be placed on the ground, to prevent the body shaking, to grasp the movement of the arm and the arm movement coordination, control the speed of the two is essential to the plane.

5, loading operation

The body should be at the level of a stable position, otherwise it is difficult to accurately control the rotary unloading, thereby prolonging the cycle time of operation; and the truck body to maintain proper distance, prevent doing a 180 degree turn when the body and the tail of the truck collided; as far as possible the left rotary mount, this vision, high work efficiency, and to correctly grasp the rotation angle in order to reduce the time for rotary truck position; rimbey excavator is low, in order to shorten the boom lifting time, and a good line of sight; first with sand, gravel, and then placed a stone, it can reduce the impact of the carriage.

6, soft zone or water operation

In the soft soil area operations, should understand the soil loose degree, and pay attention to limit the bucket digging area to prevent the occurrence of accidents, landslides and landslide body subsidence depth.

When operating in the water, should pay attention to the scope of the body allows the water depth (surface should be in the center of the roller chain); if the level is higher, the internal rotation will be due to the water into the cause of poor lubrication, engine fan blades are affected by water damage caused by water, electrical wiring components due to the intrusion of water or open circuit.

7, lifting operation

The role of the hydraulic excavator in the lifting operation, lifting the site should be recognized around the state, hook and the use of high-strength steel wire rope, lifting as much as possible the use of special lifting devices; operation mode should be selected micro mode of operation, action should be slow and balance; sling length appropriate, too long will make the hanging swing higher and it is difficult to control; to correctly adjust the bucket position, in order to prevent the steel cord spondylolisthesis; construction personnel are advised not to close to lifting objects, in order to prevent improper operation dangerous.

8, smooth operation method

During the operation, the stability of the machine can not only improve work efficiency, prolong the life of the machine, but also can ensure the safety of operation (put the machine in a flat on the ground); the drive sprocket at the rear side of the front side than in good stability, and can prevent the final drive from the impact of external force on the ground track; the wheelbase is always greater than the track, so toward the good working stability, to avoid the lateral operation; to keep close to the mining machine, in order to improve the stability and mining excavator; if points away from the machine, due to move the focus of work is not stable; lateral excavation is than mining stability, if the mining point away from the center of the machine body, the machine will be more stable, so mining point and center of body should maintain a proper distance, so that a balanced and efficient operation.

9, worth attention to the operation

The hydraulic cylinder with a buffer device, can gradually release back pressure near the end of the trip, if the impact load, the piston will directly touch the cylinder head or cylinder bottom, easy to cause the accident, so when the end of the trip should be as far as possible to stay more than.

Of bulldozer operation will cause the bucket and the working device is not a normal stress caused by rotary motion, distortion or even pin weld cracking, broken, should try to avoid such operations.

The use of body weight for excavation will cause the rotation of the bearing is not normal state, and the chassis will have a strong vibration and impact, so the use of hydraulic cylinder or hydraulic pipe to produce a greater damage.

In the loading and unloading of rock and other heavier material, should be close to the truck loading unloading, or first loading of the soil, and then loaded with rocks, the prohibition of high-altitude unloading, to reduce the impact on the truck.

The track stuck in the mud in the bucket is deep, underlying a piece of wood, the bucket bottom up track, and then in the track under the pad on the board, will be pulled out of the machine.

10, correct walking operation

When the excavator walks, should try to put away the work device and close to the body center, in order to maintain the stability; the final drive in the rear to protect the final drive.

As much as possible to avoid passing the stumps and rocks and other obstacles, to prevent track distortion; if it must be through the obstacle, should ensure that the track center on the obstacle.

A mound, always working device supports the chassis, in order to prevent the body shaking even overturning.
