Excavator backhand and backhand one-key switching valve
Different brands of excavators had their own characteristics. For example, the Sany SY 335BH excavator could switch between the left handle bucket arm action and the rotation action by entering the display screen and clicking the one-key switch button. There was no need to swap the pipeline, which was convenient, fast, safe and reliable. The Sany SY 205C excavator adopted the full electronic control technology to realize the one-key switch between the front and back hands, which made the operation more sensitive and the response faster. The Sany SY 305H excavator had the function of one-key switch between the front and back hands display screen. The reversing valve of the Komatsu excavator was located in the cab and was an important part of the operating handle. Through this valve, the left and right hands could be switched to adapt to different working environments and personal habits. Read more exciting novels for free
How to adjust the forehand and backhand of the excavator
If the excavator had a reversing switch, it was usually installed under the driver's seat or next to the rotating motor. Turning the switch could complete the switch. If there was no reverse switch, there were several methods: 1. Rotating handle: Remove the four screws of the left operating handle, rotate it 90° along with the bullet and the oil pipe, and then install it. If the rotation was changed from front to back to left and right, it would rotate 90° counterclockwise, and if the rotation was changed from left to right to front to back, it would rotate 90° clockwise. 2. Oil pipe swap: determine the action of each oil pipe control, and then swap the pilot oil pipe under the handle operation valve. 3. adjust the pipeline: switch the four pipes from the lower part of the left and right operating handles to the main control valve in parallel, that is, the four pipes originally connected to the left operating handle are connected to the lower part of the right operating handle, and the lower part of the right pipe is connected to the lower part of the left handle. 4. To adjust the body of the remote control valve: after loosening all the pipes, rotate the body of the remote control valve 90 degrees clockwise. 5. Single tube replacement: For the case of different lengths of the pipe joints, the pipe can only be removed and replaced one by one. When changing, the pipes at the P and T ports do not need to be moved. Just change 1 to 2, 2 to 3, 3 to 4, and 4 to 1 (note that some brands of models have orifices in the joints 1, 2, 3, and 4. If you change them at the back of the cab, the action will be abnormal, so it is recommended to change them at the handle). In addition, the latest fully electronic control model could be changed by setting it on the dashboard. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
backhand backhand shot
There were many ways to hit the opponent's backspin ball with a straight backhand: - [In-stage shaking (dealing with backspin balls): Similar to moving faster, using your wrist to shake the middle and lower parts of the marble, but faster and more ruthless.] - [Side Cut Shot (Against a long backspin ball)]: Similar to the action of the afterburner shot, but the racquet face is slightly tilted back, and the force is exerted from the side to violently cut the middle or lower side of the ball. The ball that bounced past spun sideways violently and was very fast, making it very difficult to return. When performing a backhand shot with a straight board, one should pay attention to the coordination of the wrist, arm, and waist to enhance the effect and lethality of the shot. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Teaching Backhand Backhand Basket
The following is the teaching content of the backhand backhand game: 1. ** How to hold the camera ** - The focus was on the thumb and index finger. The index finger was attached to the back of the board, the thumb held it up and clamped the board, and the back three fingers held the handle. Holding the board was similar to holding chopsticks. The whole body was relaxed. Only when exerting strength, he would grip it fiercely. Usually, he would keep it loose. He should avoid paying too much attention to the strength of the three fingers behind him and gripping the handle with all his strength to avoid losing control of his strength when swinging short and chopping long. 2. ** The related factors and solutions to the problem of insufficient backhand strength ** - ** The angle of the board shape **: The thumb can be adjusted when controlling the board shape with the backhand. The higher the thumb is, the more the board shape is pressed and the more force can be exerted. The lower the thumb is, the more upright the board shape is, and the easier it is to fly. When using the backhand, the thumb should be pointed up a little (it is recommended not to exceed the center line of the board), and watching excellent athletes (such as Sun Yingsha, Wang Manyu, etc.) in the backhand confrontation, it is known that their thumbs are pointed up to facilitate their own strength. When connecting the hands, the thumb needed to move up and down, and the range of movement had to be small to ensure smooth connection. 3. ** Backhand Technique Points ** - Backhand defense (for adults): After familiarizing yourself with the basic backhand drive, practice the topspin first, starting from defending against the loop drive. As your ability improves, increase the strength of the topspin. It requires the forearm to be placed higher, and the "master position's downward pressure" to receive the loop ball and hit the ball at the highest point. This technique is more practical for amateur players than close to the table. - [Backhand Backspin]: Backhand Backspin and Backhand Backspin were two techniques that were crucial to a slow dribble. At the beginning, you should find the drop point of the ball, and then take the racket toward the navel or slightly to the left. You should seek the feeling of kicking your legs and hitting your hips in one go. After you master the technique of pulling the ball down, you can practice the combination of rubbing and pulling. - ** Backhand Fast Arching **: This was a fast dial that was close to the table and had friction. The starting position was lower than the quick dial, and the board lit up. It leaned forward slightly, and the impact rubbed against the front. In a stalemate, you can take the initiative to add force and spin, focusing on establishing the feeling of the wrist, arm, and fingers when hitting the ball. - Pulling the ball in the middle: It was one of the core techniques of the horizontal board backhand. Stand about one meter away from the stage, with your feet parallel or slightly forward with your left foot. Lead the racket to the left side of your abdomen, press the plate shape, and support it with your elbows. In the beginning, you should look for the early stage of the descent to hit the ball. When you swing, you should have the feeling of facing forward first. The wrist, the inner side of the thumb, and the three or four fingers should work together. It is recommended to practice the diagonal line first. - ** Pushing (related to the horizontal swing)**: The pushing action is similar to the backhand push block of penhold grip. It does not require the player to complete the action. You just need to push the ball forward and backward. The action should be small first and then large. You can push the ball first and then push the horizontal swing. 4. ** Preparing before hitting the ball and the process of hitting the ball ** - ** Preparing posture **: Stand on the side of the front, with your feet shoulder-width apart, your center of gravity slightly forward, and the hand holding the racket in the center of your body. The racket face is parallel to the ground. - ** Waist Turn Ripping **: With the waist as the axis, turn the waist backward, and raise the arm and racquet upwards. When you take the lead, pay attention to the head of the racquet upwards and the face of the racquet facing the side. - ** Slapping the ball **: With the waist as the axis, turn the waist forward, drive the arm and the racket to swing down quickly. When hitting the ball, pay attention to the head of the racket facing down and the face facing the front. - ** Follow-up **: After hitting the ball, you still need to follow up with a follow-up action. 5. ** Grip conversion related ** - The grip usually needs to be adjusted when changing hands. There were two types of grip: the forehand grip and the backhand grip. When holding the racket with a straight grip, the racket was against the thumb and the index finger was relaxed. When holding the racket with a straight grip, the racket was against the index finger and the thumb pressed the racket. The backhand grip made it easier to adjust the angle of the racket when performing the backhand technique, and the force exerted by the wrist and fingers was smoother. When practicing the backhand and backhand conversion, muscle memory can be formed through special training. For example, if the backhand technique reaches a certain number of boards (long-term muscle memory can be formed after more than 30 days), the backhand will naturally adjust to the backhand grip. The same is true for the forehand. At the same time, high-intensity backhand and backhand conversion training, such as left-hand push and right-hand attack or two-point attack, would help to improve the conversion ability. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Backhand near 1860, backhand empty
This expression was commonly seen in the financial investment field, especially in gold trading operations. This meant that when the price rebounded (counter-draw) to the point of 1860, the reverse operation would be short (sell). This kind of operation strategy was usually based on technical analysis of price movements and judgment of market trends. For example, from a technical analysis point of view, if the previous price trend shows strong resistance around 1860, when the price is close to that point, the selling power in the market may increase, causing the price to fall, so investors will choose to go short at this position. At the same time, it was also possible to combine fundamental factors, such as the influence of macro economic data and monetary policy, to comprehensively judge the possibility of the price reversing around 1860. However, the financial market was complex and volatile. This kind of operation was risky and required investors to have rich experience, knowledge, and risk tolerance. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
I was actually defeated by a backhand and backhand
Since it was not clear what kind of sport you were talking about (such as table tennis, tennis, etc.), it was difficult to analyze the reason for being defeated. If it was table tennis, the backhand and backhand were very important in professional games. The backhand became the main scoring method after the ball was changed to 40+ points. The backhand and backhand of the professional players ranked higher were more balanced. In amateurs, a good forehand usually had a high upper limit, and a good backhand had a guaranteed lower limit. In terms of equipment configuration, most domestic athletes were equipped with sticky gloves for their forehands and sticky gloves for their backhands. However, sticky gloves for backhands were also becoming popular. If it was a shuttlecock, the backhand stroke involved many factors such as footwork, hitting point, direction of force, etc. For example, slow footwork may lead to a low hitting point, and incorrect technical movements may cause the ball to transition high. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Backhand Glue
The following are some of the routines for backhand long glue: - ** Attack pattern **: - ** Rash **: Rash can be used for no-spin balls or weak backspin balls that are the same height as the net. First, spin the forearm outward, with the backhand long rubber facing down, and then spin the forearm inward to hit the middle and upper part of the ball. At the moment of hitting the ball, the plate shape is slightly forward, and the tooth root friction ball is raised a little arc. After hitting the ball, the forearm is in a state of internal rotation, with the backhand long rubber facing up. - ** - ** Dealing with a long ball that doesn't spin **: The long rubber face first tilts forward and shines forward along with the movement. Depending on the ball's rotation, it will touch the upper or middle part of the ball. Then, the forearm will rotate inward. The surface of the ball will tilt forward to the bright board. The arc action will make the ball roll down the slope and pick up the ball. - ** Backhand position followed by forward rush, side squeeze and push **: The speed of returning the ball was only slightly slower than the incoming ball. - ** Backhand Short High Spinning High Hanging **: The racket head is knocked upwards (similar to the action of knocking the wooden fish), or the same racket hand shape is used to push the upper part of the ball to the left. The effect of the ball that is swept horizontally is similar to the effect of a high ball. - When the opponent retreated from the stage to attack the ball, the backhand sucked the short ball; when the opponent came up, the backhand dribbled the long ball; when the opponent attacked quickly, the backhand blocked the board to disrupt the rhythm. - When receiving the ball: If you can attack and pick up the ball, you will use the long rubber's good offensive ability to start playing in the first three boards. - ** Defensive Tactics **: - ** Receive the serve **: The horizontal board backhand long glue doesn't eat the serve. When you can't see the opponent's serve spin clearly, boldly use the long glue to receive it. The more the opponent turns the serve, the more the long glue can borrow the force to return the ball to the stage. If the serve doesn't turn, the long glue will also float and make it difficult for the opponent to attack. You can also learn Ito Misei's raw rubber receiving technique "side stab"(outer pocket turn, inner pocket turn). The racket touches the lower side or bottom of the ball, exerting force diagonally upward. The return ball has a side-down turn, and after landing on the platform, it turns to the side. The landing point can be in the opponent's forehand position or backhand position, which is conducive to the next hand reverse rubber attack. - ** Dealing with loop attacks **: When the opponent attacks with the loop ball, the backhand long glue will immediately reverse the spin and change from top to bottom, making it difficult for the opponent to continuously attack with the forward loop ball and can only pull the loop ball; the pulled loop ball will turn into a strong backspin ball with a long glue. If the quality of the pulled loop ball is not high, the player with the backhand long glue can score with his forehand sideways. - ** Dealing with the backspin ball **: If the long rubber ball is used as a cutting ball, the backspin can be used in a high-profile manner. Once the ball is high, it can be directly smashed. However, the high ball should not add too much friction to prevent it from falling into the net. When receiving a serve, you can push it all out. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Leg force exerted by the backhand and backhand of table tennis
In table tennis, the backhand and backhand leg forces are different. For the forehands, they needed extra strength from their legs when pulling the ball. Specifically, when preparing, the center of gravity was pressed down, and then the legs were pushed up and moved forward and upward. During this process, the force of the legs was the starting part of the power transmission. The power was transmitted from the legs to the waist and abdomen, then to the arms, forearms, and wrists, providing sufficient power for the shot. However, in a conventional forward and backhand attack, if the base was stable enough, the legs could provide enough support, and there was no need to add force to the legs. This was because the force from the legs and feet would be transmitted to other parts. On the one hand, there was not enough time, and on the other hand, the attacker would easily lose balance. In terms of backhand, when preparing to catch the ball with backhand, the left foot could be slightly adjusted to the left foot slightly back in order to draw the racket and accumulate power. Although it was not clearly stated that the leg was exerting force here, this position adjustment created better conditions for subsequent force. Furthermore, the legs could coordinate with the other parts of the body through movements such as kicking the ground. The strength could be transmitted to the arms and other parts of the body to provide strength support for the backhand. However, in the backhand technique, most of the time, the forearm and wrist should be used to exert strength. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The Technique of Backhand Backhand Cross Plate Receiving Side Spinning
There were the following techniques for catching a backhand side spin with a horizontal board: 1. In terms of preparation posture and wrist movements, when standing, keep your body stable, hold the racket in your hand, and lean your wrist slightly back so that the racket is vertical to the ground. 2. Pay attention to the angle of the racket and adjust it according to the opponent's serve, because the angle of the racket determines the trajectory of the ball and the strength of the spin. 3. When hitting the ball, the force point can be chosen at the lower part or the lower front of the ball, so as to obtain more rotation and power. 4. For the backhand side-spin joint, one must pay attention to the flexible movement of the wrist. 5. You can use backhand to flick, flick, and pick a straight line. You can also use backhand to stab the right side of the ball. The racket was relatively high, so there was no need to hold hands. During the ascent, he relied on his body to drive his forearm and control the arc forward and down. 6. When rubbing the ball, you need to find the center line of the side spin. If the center line is close to the normal line of the racquet surface when in contact with the ball, the side spin will not work. If the rubbing speed is enough, the above requirements may not be so strict, but the premise is that the ability to rub and spin is much stronger than the opponent. 7. You can also use a fixed plate to push, but this method is more limited, generally affected by side spin, but the ball's landing point is not very particular, sometimes it can use rotation to produce unexpected effects. 8. One must have a clear understanding of the rotation of the serve, determine whether the ball is left or right, and determine the direction of the ball. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
