What is a towed vibratory roller? What is a towed impact roller?

Trilateral towed impact roller Both towed impact roller and towed vibratory roller belong to towed roller. In short, they are engineering compaction machinery that does not have walking function and needs to work under the drive of traction machinery. Quadrilateral drag impact roller Among them, the impact roller of the towed impact roller is non-circular polygonal structure, according to the different shape structure, divided into three-sided impact roller, four-sided single-wheel impact roller and five-sided two-wheel impact roller. Self-propelled pentagonal impact roller The working principle of the towed impact roller is the same as that of the self-propelled impact roller. The impact force of the three-sided impact roller is relatively large, which focuses on the impact compaction of the roadbed. The force of the four-sided impact roller is moderate. Both of them can be used for compaction of the roadbed and pavement crushing. Moreover, the four-sided impact compactor is designed with a single wheel, and the pavement is relatively narrow, the impact force of the pentagonal impact compaction wheel is relatively weak compared with the three-sided impact compaction wheel, which is mostly used for road crushing and impact compaction of silty soil and sandy soil. self-propelled vibratory roller The working principle of towed vibratory roller is the same as that of self-propelled vibratory roller. It also relies on self-weight and exciting force to force the compacted material to do vertical forced vibration, which sharply reduces the internal friction between soil particles and achieves the purpose of compacting soil. The size of the exciting force can be adjusted as needed. towed vibratory roller Towed vibratory rollers are rollers with single steel wheel structure. According to different weight and different output power, it is divided into light towed vibratory roller and heavy towed vibratory roller. Generally speaking, if the weight of the equipment is less than 10 tons, it can be defined as a light towed roller. Due to different requirements of construction specifications, it is widely used abroad. light towed vibratory roller Equipment with a weight of more than 14 tons is called heavy towed roller, which is widely used in China. Heavy towed vibratory roller is an indispensable compaction machinery in the foundation construction of highways, railways, dams, airports and other large-scale projects, especially for large-scale filling construction, when the compaction degree is required to be more than 95%, it shows the necessity and efficiency of this kind of machinery. Heavy towed vibratory roller Light towed vibratory roller and heavy towed vibratory roller are used in different ranges, and different towed rolling wheel quality or exciting force can be selected according to different compaction thickness and materials. In addition, due to the small weight of the vibrating wheel, the power output of the light towed vibratory roller is mostly borrowed from the power output of the tractor, while the heavy towed vibratory roller is mostly equipped with high-power power output.
