What performance index parameters should be considered when purchasing a roller?

[aminaas1575]

The general parameters of the roller performance index include vibration frequency and amplitude, linear pressure, weight and traction, running speed and lifting ability. Reasonable adjustment and control of these will have a direct impact on the construction efficiency and quality.

Frequency and amplitude of vibration
The vibration frequency refers to the number of vibrations per minute, and the amplitude refers to the maximum vibration amplitude of the vibrating wheel or vibrating steel wheel. The vibration frequency and amplitude are two of the main performance indicators of the roller. Their functions are to increase the compaction force, improve the density and stability of the soil, and improve the bearing capacity and durability of the road surface. Generally, the vibration frequency and amplitude are inversely proportional, that is, the higher the vibration frequency, the smaller the amplitude; the larger the amplitude, the smaller the vibration egypt number data frequency. In order to achieve better compaction effect, it is necessary to adjust the vibration frequency and amplitude according to different road sections and different soil conditions.

Linear load
Linear load refers to the load per unit length of the roller or tire. It determines the compaction capacity and compaction depth of the roller, and is closely related to the frequency and amplitude of vibration. Generally, the larger the linear load, the stronger the compaction capacity, but the degree of damage to the road surface should also be considered. In addition, the distribution of the linear load should be considered and controlled during construction to avoid excessive concentration, causing damage to the road surface and poor compaction effect.

Weight and traction
Weight and traction are also one of the main performance indicators of the roller. They directly affect the magnitude of the compaction force and the level of construction efficiency. In general, the greater the weight, the greater the traction, the greater the compaction capacity and the compaction depth of the road surface; conversely, the lower the weight, the less the traction, and the lower the efficiency. When selecting a roller, the appropriate weight and traction should be selected according to the actual needs of the work and the site conditions.
