How do you drive the forehand and backhand drive of an excavator?
Forehand and backhand are domestic terms.The operation method from the original machine in Japan is backhand: the left handle controls the bucket before and after, and the backhand is controlled by the left and rightThe domestic production method of excavator is said to be forehand: left hand handle, left or right control rotation, the left handle, front and rear control bucket excavator is forehandThis thing and foreigners driving, steering wheel in the car to the right, Chinese driver's cab is on the left side of the car. Reversing valve, loosen the screws to break, you can change an action, a total of four adjustable! No, the handle is removed, change the oil line, the tube before and after the change with the left and right, you can adjust the backhand.
As we all know, the hydraulic excavator operation is accomplished through two handles, two handle before and after, left and right four directions, respectively control the excavator and the moving body part arm, bucket rod, and the rotating bucket. But according to the corresponding way, the operation mode of excavator is divided into two kinds, "left and right spin" and "front and back rotation". Then, I will talk about some differences between them.Two modes of operationThe first kind is the Japanese second-hand import machine and senior veteran driver as the representative, the left hand handle of the front, back, left and right corresponding control is the excavator's right rotation, left rotation, bucket extension and bucket recovery. We used to be referred to as "front and back spin"".The second type is the domestic new machine and the new generation of young drivers as representatives, left hand handle of the front, back, left, right, respectively, corresponding to the control of the excavator's bucket stick, bucket recovery, left rotation and right rotation. We used to be referred to as "left and right spin"".There are people who have called these two modes, "mobile phone" and "mobile phone", but due to the lack of a unified nomenclature, caused the differences on the way, before and after rotation is called mobile phone, the mobile phone is called reverse rotation, but also to rotate around the mobile phone is called, before and after the rotation is called reverse mobile phone. So to avoid confusion, said only this, before and after the rotation and rotation, to note here is "mobile phone" is refers to the rotation, and rotation or rotation before and after the "anti mobile phone", two kinds of the different mode of operation is only the left hand excavator operating handle, right invariant handle mode.
Is the so-called mobile phone and mobile phone anti refers to your left hand operation mode, it refers to the left hand lever before and after the mobile phone is telescopic arm, left and right is right and left rotation, and vice versa is mobile phone operating lever before and after rotation, telescopic arm is around. The pros and cons of mobile phone operation depends on your own habits. When I first contacted the excavator, I operated a positive cell phone. Then switched to mobile phones. Personally, the design of mobile phones is relatively user-friendly. It's easier to use. By contrast, it's much more comfortable to operate than a cell phone.
