How is the Dump Semi-trailer Designed to Reduce the Overall Height
First, side dump semi trailer, because of its operational way, is relatively easier to avoid the problem of height limitation than others, by selecting a production with a height of less than 3 meters, and the range of height is relatively large. However, it is not so easy for the backward dump trunk to avoid this problem. The difficulty is that the height of the cylinder which is placed in the front is generally about 3.4 meters off the ground. And the installation space is fixed, so it is hard to lower the overall height from the installation position of the movable top seat.
To solve this problem, it is necessary to work hard on the oil cylinder of the side dump semi trailer. The oil cylinder is the main part of the rear dumping and unloading. Through the expansion and contraction of the oil cylinder, the car body can be tilted. The telescopic stroke of the cylinder determines the tilt angle of the box. Generally, taking the 8.5m back flip as an example, the fully extended stroke of the cylinder is about 6.18 meters. The tilt angle of the box is greater than 30 degrees to meet general unloading requirements. The grade oil cylinder is generally divided into 5 sections, which are extended one by one according to the cylinder diameter from large to small.
If you want to lower the height of the cylinder, you can actually adjust the cylinder's own structure, that is, make the cylinder's piston rod into 6 sections, so that although the stroke of each section is short, the number of sections is added, which can not only ensure the 6.18-meter extension stroke of the dump semi-trailer, but also reduce the height of the cylinder when the cylinder is fully retracted, thereby reducing the overall height of the vehicle.
