Little knowledge about excavators
|Excavator boom arm|
The small arm of the excavator is a laborious lever, and the pin in the middle is the fulcrum. Up is the big arm, down is the forearm! The longer the arm, the less effort it takes, on the contrary, the more effort it takes! At this time, the boom is the longest, so the digging force of the forearm is the largest at this angle!
The advantages are: 1. Improve the working efficiency of the excavator and reduce fuel consumption, 2. Reduce the friction and loss of each pin shaft, 3. Reduce the metal fatigue of each part of the excavator.
|Excavator Bucket|
The bucket is also a labor-intensive lever principle, and the excavator can reach its maximum when the boom is the longest. The angle between the teeth and the ground is preferably about 35 degrees in hard soil, and 45 degrees in general soil, because this angle can maximize the pressure. At this time, the digging distance is the shortest, and the extension length of the forearm is also reduced. The longer the forearm, the smaller the digging force.
The advantages are: 1. Improve the working efficiency of the excavator and reduce fuel consumption, 2. Reduce the friction and loss of each pin shaft, 3. Reduce the metal fatigue of each part of the excavator.
|Excavator rotation|
Excavator rotation work is also a laborious lever. The farther the forearm is stretched, the more laborious it is. Therefore, try not to extend too far when using rotation operations, and this kind of operation method should be reduced. The picture above is an example of the error.
Try to reduce the length of the forearm, it will be more powerful. Don't sweep so much at a time, and don't impact the operation, so as not to damage the rotary system and each pin shaft.
|Excavator Guide Wheel|
When steering on uneven ground, try to prop up the side of the guide wheel to turn, but it should not be too high, depending on the terrain.
The advantages are: 1. Increase the turning speed. 2. It can reduce the force on the side of the guide wheel of the excavator on the uneven road, so that the life of the guide wheel is longer. 3. It can reduce the lateral force on the track on uneven roads, thereby increasing the life of the track and the life of the rollers.
Of course, there are certain disadvantages: 1. It has certain side effects on the market. 2. Excessive pressure on the drive wheel.
If there are stones on the road surface, it is best to choose to bypass them, and do not use the side of the track shoes to press them. This will cause excessive force on a single track, damage the track shoes, and seriously break the chain tendons. If you can't go around, use the middle of the track to press down, prop up the car to walk, and minimize the impact of stones on the track.
