Anmai ABG double hammer ironing plate with real-time stepless adjustment

    The ABG brand under the Anmai Group is renowned worldwide for its leading paving technology, among which the double hammer screed has long been a benchmark in the field of high-quality road construction. Nowadays, this technology has undergone a significant upgrade: the brand-new VDTA-V hydraulic telescopic double hammer screed can adjust the stroke of the front hammer in real time and steplessly during the paving process, bringing unprecedented flexibility and precision to the paving operation.

Real-time adjustment, no need to stop the machine

    In the past, due to the cumbersome operation required for adjusting the Settings of the hammers, construction workers often chose to compromise by adjusting the speed of the hammers and other means. However, this approach is not precise enough and can affect the operating condition of the paver, and even accelerate the wear of equipment components.

    Nowadays, the VDTA-V hydraulic telescopic double tamper screed can be steplessly adjusted through the operation panel. There is no need to preset the gear. Just by touching the button, the stroke of the front tamper can be adjusted according to the actual working conditions, thereby precisely controlling the pre-compaction effect. The rear rammer is kept in a fixed setting to maintain consistent molding quality.

Now, with just a light click of the button, we can truly unleash the full potential of the double hammer ironing technology. Frank Dorrie, the global product manager of ABG, said. The outstanding ironing technology of ABG pavers makes the industry's evaluation that "all materials can be laid" even more well-deserved.

    Under the global advocacy of low-carbon construction, low-temperature asphalt (LTA) is being adopted by an increasing number of projects due to its significant reduction in CO₂ emissions and fuel consumption. However, the compaction window of LTA is more compact, which puts forward higher requirements for the paving process. Through the main and auxiliary double ramming hammer system, VDTA-V compacts the mixture twice each time, significantly enhancing the pre-compaction effect and avoiding insufficient density due to temperature loss.

The advantage of immediate response

    It is a common working condition to continuously lay structural layers of different thicknesses (such as a 10 cm base layer and a 4 cm surface layer) on the same day. However, traditional ironing plates cannot flexibly switch the hammer stroke without interrupting the operation, often resulting in insufficient compaction of one layer or excessive compaction of another layer. The VDTA-V screed can quickly adapt to different layer thicknesses. During the paving process, the stroke of the front rammer can be adjusted in real time and steplessly, taking into account both density and flatness.

    VDTA-V supports independent adjustment of each section of the ironing plate, with a stroke range from 0.5mm to 10mm. For instance, when laying curves or circular islands, the inner side of the ironing plate has a smaller coverage width and needs to be set with a shorter stroke, while the outer side requires a longer stroke. Operators can achieve precise compaction in different zones by gradually increasing the stroke from the inside out, thereby effectively avoiding overcompaction or insufficient compaction.

    The VDTA-V hydraulic telescopic double hammer screed also has the following advantages: The hammer bearings do not require daily lubrication throughout the construction season; The front hammers are heated independently, making the temperature distribution on the surface of the ironing plate more uniform. The new diagnostic system can quickly detect the operating status of the heating elements on the ironing plate, improving maintenance efficiency.

A consistent pursuit of quality

    ABG was the first in the industry to introduce the double hammer ironing plate and applied for it. The early single-hammer system won with its uniform compaction, while the double-hammer system made further progress in terms of density, forming effect and construction efficiency. The emergence of VDTA-V not only attests to Anmai's profound background and continuous innovation in the field of paving equipment, but also marks that the ABG double hammer screed technology has completed a comprehensive evolution from "structural leadership" to "operational leadership".

    Whether it is dealing with complex working conditions, environmentally friendly new materials, or taking into account the dual requirements of construction efficiency and quality, the VDTA-V hydraulic telescopic double hammer scree of Anmai ABG is the ideal choice for the construction of high-grade roads worldwide.
