Dump semi trailer back or side?
As a special purpose vehicle with a large market share, self-discharging semi-trailer is widely used in the transportation of loose goods such as sand, gravel, soil and coal. Its loading carriage can automatically tip over at a certain Angle during unloading, which greatly saves unloading time and labor, shorens transportation cycle and improves production efficiency.
At present, the self-dumping semi-trailer on the market is mainly divided into two kinds: post-tipping self-dumping and rollover self-dumping. Which one is applied to the transportation of goods with higher safety performance?
A brief look at the main differences between a rollover semi-trailer and a rollover semi-trailer:
1. Site requirements: Under normal circumstances, tip-over dump trucks require the unloading site to be large, wide and flat, while rear tip-over dump trucks do not have too many requirements for the width of the site. They only need to be flat and without shelter, which is relatively free.
2. Model requirements: rollover dump truck is generally used in heavy-duty vehicles or trailers with cargo car length greater than 9.6 meters, and rear rollover dump truck is more used in standard load or short wheelbase vehicles.
3, lifting form: rollover type dump truck lifting height is low, so the body center of gravity is relatively low when unloading, but also because of its lifting way, its unloading beam easy uneven stress; In contrast, the lifting height of the rear tipping dump truck is larger, and the center of gravity of the vehicle is easy to lean toward the tail when unloading, causing the warped head, especially when unloading from the slope to the slope.
The two forms of self-discharging semi-trailer are prone to instability if the unloading is not well controlled. However, rollover dump trucks generally need to be equipped with shifting rods, so this rollover accident can be reduced to a certain extent, but it can not be completely avoided, and it also needs strict and standardized operation.
Under normal circumstances, the dump truck semi-trailer transport is a large weight of goods, so the requirements for the vehicle chassis to be higher. The trailer axle, in particular, is not only the key component of the chassis bearing, but also related to the performance of the vehicle braking, driving and so on. It must be 100% reliable. There are many axle brands on the market, which is worth buying? DARO Heavy Industry Group is Liangshan's first mass production of integrated trailer axle enterprise, has accumulated 20 years of experience, with 32000 square meters of standard chemical plant, from the next to the assembly of fifteen production processes, trailer axle strength, toughness, elongation, fatigue resistance and other leading performance, for owners to provide higher security at the same time, improve vehicle operation efficiency.
