High speed hydraulic compactor, also known as "hydraulic impact compactor" or "hydraulic dynamic compactor", can be divided into excavator hydraulic compactor and loader hydraulic compactor. It is a new type of compaction engineering machinery in recent years, consisting of load-bearing organization, compactor frame, compactor, lower hammer head, buffer equipment, hydraulic system, electronic control system, etc. It is directly installed on engineering machinery such as loaders and excavators, and directly borrowed from excavators Hydraulic power output of machinery such as loaders.

Impact rollers, also known as "impact rollers", "plum blossom impact rollers", "impact rollers", etc., are divided into self-propelled impact rollers and towed impact rollers. They are also a new type of compaction engineering machinery in recent years, composed of traction organizations, non circular impact rollers, and other components. The impact compaction wheel drives the impact compaction wheel to work under the traction of traction equipment. Currently, towed impact rollers are widely used in the market.

The common characteristic of Shandong compaction machine manufacturers is that both use huge impact force to compact the foundation, and the huge kinetic energy is converted into impulse in a short period of time, that is, the instantaneous effect of the huge impact force, which can generate significant shear stress and normal stress in the soil, effectively overcoming the cohesive force of cohesive soil, tightening the soil and sweeping away some air and water in the soil. Due to the short duration of the impact effect, the impact is often completed before the material under pressure can "move". Therefore, it can reduce the instability caused by soil "movement" and can be effectively used for compaction of clay and dry sand with high water content, as well as for crushed stone roadbed.

Both high-speed hydraulic compactors and impact rollers use enormous impact force to compact the foundation. Early cleaning is a common feature between high-speed hydraulic compactors and towed impact rollers, and there are still certain differences between the two. The high-speed hydraulic compactor uses the principle of compaction method construction, which uses the impact force of the hammer falling to compact the foundation. It is widely used in small-scale earthwork projects such as bridge abutments and culvert backs.

The plum blossom impact roller, on the other hand, combines the construction principles of compaction and rolling, and is commonly used in large areas of fill, such as flat sites, airports, reservoirs, highways, and other projects.
