Luoyang road roller manufacturers believe that road rollers have wider requirements for filler moisture content, which can be reduced by 3%-5% in the up and down direction. Basically, after filling and leveling the soil, the advantages are more obvious, especially in arid or semi-arid areas. The moisture content in these areas is very low, some approaching 0%-1%. The impact roller only needs to spray a small amount of water on the surface to be rolled, which greatly reduces the compressed water and reduces the construction cost.

Luoyang road roller manufacturers believe that the road roller can directly roll fillers on the existing ground (old roads), and the thickness of each layer of fillers is greater than 0.6-1m, which can replace excavation and layered rolling and improve construction efficiency. The rolling compression area of the small roller per hour is 4 times that of the traditional roller, and the compression volume is 8 times that of the traditional roller. Rolling construction in large workshops can give full play to its faster function.

Luoyang road roller manufacturers believe that tire rollers can also increase or decrease counterweights and change tire inflation pressure, which is more conducive to the compaction of various materials. Based on the above characteristics, tire rollers are widely used in the compaction of base layers, sub-bases, fills and asphalt surface layers of various materials; especially in asphalt pavement compaction, the flexible compaction function of tire rollers is an advantage over other compaction equipment. It is irreplaceable and therefore becomes the main machine for re-compressing asphalt mixtures and is also an ideal compaction equipment for the construction of high-grade highways, airports, ports, embankments and industrial construction sites.

Luoyang roller manufacturer believes that the impact wheel consists of two non-circular impact wheels and a shaft head assembly, and is the main working part of the impact roller. The impact wheels are placed on both sides of the frame and connected by the axle head assembly. Under the action of the traction device, the impact wheel rolls forward, and the height of its center of mass continues to increase and decrease, producing a combined impact of kinetic energy and potential energy on the ground to achieve rapid compaction.

Luoyang roller manufacturer believes that due to the working characteristics of the impact wheel, when it impacts the ground to perform work, it will also impact the frame laterally and longitudinally. To this end, the impact wheel axle head assembly is connected in the middle through a swing rocker, which meets the needs of vertical movement and non-uniform motion of the center of mass of the impact wheel, thereby achieving linkage with the frame. The rocker, buffer rubber block and buffer hydraulic cylinder interact to achieve the purpose of buffering and avoid the impact of the impact wheel on the traction device.

Luoyang roller manufacturer believes that the frame is welded into a box-shaped structure by steel plates, with a traction mechanism installed in the front, a rocker connected in the middle, and a lifting hydraulic cylinder installed in the rear. The entire frame is supported by four solid rubber tires to complete short-distance transportation and site transfer. Because the impact roller itself has no power, it needs the traction of a tractor to work. In order to prevent the horizontal impact force generated when the kinetic energy of the impact wheel changes from damaging the tractor and enable the driver to have a good and comfortable working condition, a two-way buffer device is specially designed in the traction mechanism.
