Who We Are
We Design, Manufacture & Supply RIC Equipment Worldwide
As one of the earliest manufacturers of Rapid Impact Compaction (RIC) equipment in China, we design, produce, and supply machines to contractors worldwide. Our machines have been proven in large-scale infrastructure projects, but we manufacture the equipment - we don't do the construction.
The Rapid Impact Compactor drop weights are available in 3.5 t, 5 t, 7 t, 9 t, 10 t, 12 t, 14 t, 16 t, and 20 t, with an effective compaction depth ranging from 1.2 m to 9 m. Every component is designed and manufactured in our own facility - from hydraulic systems to control units. Our company is built around product development, factory production, technical service, and long-term equipment support to contractors and construction companies.
Cao Bin, the founder and chief engineer of Taian Hengda Machinery, is officially recognized as the inventor of hydraulic Rapid Impact Compaction (RIC) in China. Before founding the company, Cao Bin was a designer of China's strategic missile launch vehicles, bringing military-grade precision and reliability to civil engineering equipment.
In 2002, Cao Bin filed the founding patent for the "Impact Hammer," marking the birth of China's first domestically-developed hydraulic rapid impact compaction machine. By 2003, the first prototype was completed in Taian, Shandong Province. After rigorous testing by the Xi'an Highway Machinery Testing Center under the Ministry of Transport, the technology was evaluated by the Beijing Municipal Science and Technology Commission in January 2004 with the conclusion: "Domestically pioneering, reaching international advanced level."
Taian Hengda Machinery Co., Ltd. is a manufacturer with its own factory, specializing in the production and sales of hydraulic Rapid Impact Compaction (RIC) equipment. We supply equipment to construction contractors - we are not a construction company ourselves. Our technology had already proven itself on major highways across China. Today, Taian Hengda holds over 70% of China's domestic market share in RIC equipment manufacturing.
State-of-the-art manufacturing facility in Taian, Shandong Province. Our modern production lines combine precision engineering with strict quality control, ensuring every RIC machine meets international standards. We manufacture and sell equipment to contractors worldwide - we are not a construction contractor.
23 Years Growing with China's Infrastructure Boom. While we have "only" 23 years of manufacturing experience, we grew alongside China's massive infrastructure development. Our equipment has been tested and proven on thousands of projects, continuously improved based on real-world performance. Today, our machines are deployed at scale in Saudi Arabia and UAE, trusted by international contractors for their most demanding projects.
How we replaced imported equipment and established China's technological independence
Cao Bin completed the design and prototype in just one year. The first Chinese-made rapid impact compaction machine was born in Taian, Shandong, with completely independent intellectual property rights.
Deployed on the Meihe Expressway in Guangdong Province (150+ km), the equipment performed flawlessly through the rainy season with zero settlement issues.
The Hong Kong Airport Third Runway project, using 60+ Hengda RIC machines, was evaluated by the China Water Transport Construction Industry Association as reaching "International Advanced Level" with a score of 80/100.
The world's largest reclamation airport expansion project - A testament to our technology's reliability
"This project pioneered the large-scale application of rapid impact compaction technology in international reclamation projects, establishing a new standard for artificial island ground treatment."
— Technology Evaluation Committee, China Water Transport Construction Industry AssociationTrusted by major infrastructure projects across continents
We are not a copycat or follower. Cao Bin is the official inventor recognized by the Chinese government. Patent No. filed in 2002 is the founding patent of China's RIC technology. All subsequent developments are based on our original innovation.
The Hong Kong Airport project deployed 60+ units simultaneously - the largest RIC deployment in history. This wasn't a trial or pilot project; it was the main construction method for 8 million cubic meters of ground treatment. No other manufacturer has demonstrated this level of reliability and scalability.
With 70%+ market share in China, we are the industry standard. Major contractors including China Railway Group, China Harbour Engineering, choose our equipment for their most critical projects.
From HC04 (4kJ) to HC300 (300kJ), we offer 14+ models covering all application scenarios. Whether you need shallow compaction for residential projects or deep treatment for airport runways, we have the right solution.
Now in the 7th generation of technology evolution. The latest models feature advanced control systems with 7 functions including automatic positioning and data collection. We invest heavily in R&D to maintain our technological leadership.
Successfully serving projects in Saudi Arabia, UAE, Indonesia, Cambodia, Maldives, Angola and more. We understand international standards, work with global contractors.
Trade terms, delivery schedules, after-sales service, warranty and spare parts support
Our standard price basis is CIF Qingdao Port, China. FOB and FCA quotations can also be prepared when you provide the destination port. The quotation clearly identifies inland delivery, port charges, ocean freight, insurance, and export documentation included under the selected Incoterm.
For one unit, delivery to the designated port in China is generally arranged within 30 working days after receipt of the advance payment. The schedule for multiple units depends on the confirmed quantity and models. The equipment is shipped in modules, and the referenced HC series arrangement normally uses one 40-ft open-top container.
Remote video guidance is available for installation and troubleshooting. Using the machine model and serial information, photos, videos, and operating data, our technical team can help diagnose issues and guide inspections, adjustments, or component replacement. On-site service can also be arranged when required under agreed service conditions.
Standard warranty coverage is provided according to the sales contract. We can supply cushion pads, hydraulic cylinders, sensors, control boxes, control cables, and other wear or support components for the relevant model. A recommended spare-parts package can be quoted with the equipment to reduce future downtime.
