1、 First, let's talk about the design direction of the same displacement of the cab and the mixing tank. The design of the integrated same displacement of the cab and the mixing tank is conducive to the driver to better observe the position and discharge volume of the discharge port during discharge to a certain extent, improve the accuracy, and achieve a more accurate control over the discharge control.
But at the same time, the disadvantages should not be underestimated. On the one hand, when the cab rotates synchronously with the tank, the driver is in a state of back and forth movement, and is moving along a circular track with a radius of about three meters. In many cases, the line of sight is in a suspended state. In such cases, the driver is prone to fatigue, There is also a very important problem. For the design of the same displacement, the cab is integrally installed on the tank, which virtually intensifies the bearing strength of the bottom rotary table, which is undoubtedly a great hidden danger for the long-term operation of the rotary table.
If it is only the need to improve the unloading accuracy, a camera can be installed at the rear-view mirror of the mixer truck to synchronously display the discharge in the cab. I believe this problem can also be solved.
2、 The design direction of whether the loading bucket and can body are integrated. At present, many manufacturers have slowly improved the installation mode of the loading bucket and began to separate the loading bucket from the can body. The bucket direction is fixed in a place parallel to the cab rather than installed on the can chassis. The benefits of this improvement are obvious. On the one hand, the direction of the bucket itself needs to be synchronized with the cab before shoveling. In addition, the weight of bucket and boom can not be ignored. It is installed on the tank chassis for a long time, and the direction of gravity is reflected on the chassis, which always acts on a point of the turntable. In this way, it will also cause great damage to the chassis.
3、 In the early stage, some manufacturers used the tire combination of the first four and the second. From the perspective of laymen, this design really improves the bearing capacity of the whole vehicle. However, people engaged in the concrete industry know that most of the working environment of the mixer truck is relatively complex and rugged road conditions. If it is the tire combination of the first four and the second, between the two adjacent tires, It is inevitable that some foreign matters such as stones will be squeezed in. When passing through a pothole Road, the load will increase instantaneously, and the damage to the tire is irreversible. If it is serious, it will be scrapped directly. Friends who have played with a cart or repaired should have seen a lot of this situation.
