Impact roller

Impact roller is a new type of construction machinery and equipment derived from the combination of tamping and rolling. It has the construction characteristics of tamping and rolling at the same time. Impact is the construction characteristic of tamping, and rolling is sometimes the characteristic of rolling. .
The higher the impact rolling speed, the stronger the "kneading" of the impact roller. Under the combined external load of "impact" and "kneading", the soil particles of the foundation are more likely to overcome the frictional resistance between the particles to generate sliding and rolling displacement, and then fill in a more concealed and stable position, resulting in void volume compression, so that the base surface can be compressed. more solid.
In the rolling speed range of 10-15 km/h, the higher the speed, the better the construction effect of impact rolling. Under the superposition of speed, the large-amplitude and low-frequency output of the non-circular rolling wheel of the impact roller will generate a very high peak pulse force, which is equivalent to more than 5 times the line load of the rolling wheel of the vibratory roller, and the output energy value is extremely high.

Features of Impact roller:

1. Accumulators, hydraulic cylinders, and compression springs on the traction shaft are used for buffering to eliminate the impact of shocks on the tractor.
2. Operate the lift cylinder, and the impact wheel is supported by the trailer to leave the ground, which can be used for short-distance transition without damaging the road surface.
3. The hydraulic oil comes from the hydraulic system of the tractor, and is connected by a quick-change joint, which is convenient and fast.
4. During the work, bulldozers, graders and sprinklers can be selected to facilitate more effective compaction.
