Field-Proven Power for Infrastructure: Jiangsu Anteng AC Series Impact Hammers Adapt Efficiently to Diverse Pile Foundation Projects

Jiangsu Anteng's AC series hydraulic impact hammers are environmentally friendly, energy-controllable, highly penetrative piling equipment designed for complex working conditions. Covering AC-3, AC-5, AC-8, AC-10, AC-12, AC-15, AC-18 and AC-40 models, the series is widely used in transport bridges, municipal infrastructure, photovoltaic and wind power projects, urban renewal and other scenarios. With a compact body, stable power and broad adaptability, the equipment can handle narrow sites, complex geology and many other working conditions. Proven by numerous domestic and overseas projects, it has become a highly reliable and cost-effective choice in the pile foundation construction sector.

1. Core Product Advantages

The AC series impact hammer adopts a single-cylinder core lifting structure, enabling rapid installation and site transfer without complex modification. Transport and construction are flexible and efficient. Stroke and impact frequency support stepless adjustment, with both manual and automatic modes. Parameters can be adjusted in real time for sandy soil, clay, pebble layers, weathered rock and other geological conditions, preventing pile slippage in soft soil and delivering strong penetration in hard layers. The series is compatible with various pile types.

Core components are forged from high-strength alloy and matched with dedicated sealing and independent cooling systems. The equipment is wear resistant, heat resistant and impact resistant, allowing long-term operation in humid, hot and harsh outdoor environments with low failure rates and reduced maintenance costs.

2. Project Case: Hunan Changqiao-Nanchang North Second Ring Expressway, AC-12

As a main model in the series, the AC-12 offers a balanced combination of machine weight and power, focusing on municipal expressways, bridges and medium-to-large-diameter pile foundation projects. It demonstrated strong construction capability in the key Hunan Changqiao-Nanchang North Second Ring Expressway project.

The project is a key transport project under Jiangxi's 14th Five-Year Plan, with strict construction standards and a tight schedule. Its core construction task involved load-bearing steel pipe piles for bridges, with a designed pile diameter of 820 mm and pile length of 27 m. The geological conditions were complex: the upper layer consisted of silty clay and loose sand, while the middle and lower layers contained pebble beds and strongly weathered argillaceous sandstone. Penetration was difficult, and because the site was close to villages and towns, noise and vibration control requirements were strict.

To balance construction efficiency, pile quality and environmental requirements, the contractor selected the Jiangsu Anteng AC-12 hydraulic impact hammer after multiple comparisons. The model provides stable impact energy of 180 kNm and stepless frequency and stroke adjustment, accurately adapting to changes in composite strata. It is compatible with the onsite 25-30 ton crawler crane, enabling flexible positioning and transfer. During construction, power output remained continuous and stable, with no hammer jamming or bouncing. The project achieved an average of 40-50 piles per day, improving efficiency by more than 40% compared with traditional equipment.

As major infrastructure develops toward deeper, farther and harder working conditions, Jiangsu Anteng's AC series hydraulic impact hammers are becoming the first choice for more construction companies thanks to solid technology and rich field experience. Whether in deep-water areas of sea-crossing bridges, narrow commercial district jobsites or offshore wind power fields, the AC series proves through successful pile sinking that Anteng is a trusted partner for hard geology.
