Kowy Unveils Prototype of Large-Diameter Rebar Tying Machine RT-828 for 85mm Applications

NINGHAI, China – Kowy Electric Tools, a specialized manufacturer of construction binding solutions, is developing the RT-828 – a next-generation large-diameter rebar tying machine capable of binding stacked and crossing reinforcement bars up to 85mm. Currently in the testing phase, the machine is engineered to deliver exceptional speed, portability, and wire-saving performance for heavy-duty construction projects.

Addressing Evolving Market Demands

As infrastructure projects grow in scale and complexity, reliable and efficient solutions for large-diameter rebar tying have become essential. Traditional manual methods often lead to inconsistent results, excessive wire usage, and project delays.

The RT-828 has been designed to overcome these challenges. Leveraging Kowy’s decade-long expertise in automated binding technology, it incorporates an upgraded motor and an advanced feeding mechanism that ensures precise and efficient tying of thick, multi-layer rebar configurations.

Engineered for Efficiency, Portability, and Material Savings

Preliminary tests highlight three key advantages of the RT-828:

1. High-Speed Tying

The RT-828 completes a secure tie in under 1.2 seconds – significantly faster than most existing large-diameter tying tools – enabling construction teams to maintain productivity without compromising on binding quality.

2. Lightweight and Ergonomic

Weighing only 4.2 kg and featuring a low-vibration, ergonomic design, the RT-828 allows for comfortable operation over extended periods. Its compact structure and quick-loading spool system also enhance mobility and reduce downtime on-site.

3. Reduced Wire Consumption

Equipped with Kowy’s proprietary tension-control technology and an optimized tying path, the RT-828 cuts wire waste by up to 20% compared to conventional machines, lowering material costs and supporting sustainable construction practices.

Advanced Features for Demanding Job Sites

In addition to its core strengths, the RT-828 integrates several user-focused innovations:

· Interchangeable spools compatible with standard and high-tensile wires

· IP54 rating for dust and water resistance

· Smart diagnostics with LED alerts for maintenance and troubleshooting

· Modular design for easy servicing and part replacement

Next Steps: Testing and Launch Plans

Kowy’s R&D team, led by Product Director Mr. Hua, is conducting field tests with selected construction partners to evaluate the machine’s performance in real-world settings such as bridge construction, high-rise buildings, and industrial foundations. Feedback from these trials will guide final refinements ahead of its anticipated commercial launch in Q4 2024.

“We are committed to providing machinery that not only meets but anticipates the needs of the global construction industry,” said Mr. Hua. “The RT-828 represents a meaningful step forward in making large-diameter rebar tying faster, more efficient, and more economical.”
