What is a heavy-duty roller?

Heavy-duty rollers are equipment used in engineering machinery to compact soil, asphalt mixtures or other construction materials. They are widely used in large-scale infrastructure projects such as highways, railways, and airport runways. It is characterized by its large weight and strong compaction ability, which can effectively improve the compactness and stability of the foundation. The following will introduce the heavy-duty roller in detail in terms of definition, classification, application scenarios and technical parameters.

1. Definition and classification of heavy-duty rollers

Heavy-duty rollers can be divided into three categories according to their working methods: vibratory rollers, static rollers and tire rollers. Vibratory rollers enhance the compaction effect through high-frequency vibration, static rollers rely on their own weight for compaction, and tire rollers use the kneading effect of pneumatic tires to increase compaction.

2. Core parameters of heavy-duty rollers

The following is a comparison of the technical parameters of typical heavy-duty rollers, based on recent industry reports:

3. Recent industry hot spots and technological progress

According to the search data of the entire network in the past 10 days, hot topics in the field of heavy-duty rollers focus on three aspects: intelligence, new energy and efficient compaction technology:

4. Application scenarios of heavy-duty road rollers

1.highway construction: Used for layered compaction of roadbed, requiring compaction degree ≥95%;
2.Airport runway construction: Need to meet FAA/ICAO standards, usually using equipment above 36 tons;
3.dam project: Use sheep's foot grinding variant model for clay materials;
4.urban road reconstruction: Miniaturized heavy equipment (such as 10-14 tons) is more popular.

5. Precautions when purchasing

It is recommended that users consider the following factors based on project needs:
• Type of compacted material (asphalt/soil/mix)
• Project scale (continuous operation time)
• Environmental requirements (noise/emission standards)
• Intelligent requirements (data collection/remote monitoring)

According to the latest data from the China Construction Machinery Industry Association, the number of heavy-duty rollers in the market has exceeded 120,000 units in 2023, of which models above 30 tons account for 35%, and the annual growth rate of intelligent models exceeds 40%. In the future, as "new infrastructure" advances, demand in this field will continue to be high.
