This is a "rotating arm attachment" that rotates from the base of the heavy machinery's arm and aligns the tilt function with the nipper function. The arm will be custom-made to your specified length. It can be retrofitted to existing heavy machinery and is compatible with major heavy machinery manufacturers worldwide. We are fully prepared for installation, operation guidance, and after-sales service. The developer is KYUNGWONTECH from South Korea, which has a strong track record with Japanese-made heavy machinery and sells 300 units annually in Korea. We are aiming for the Japanese market and have obtained a Japanese patent. If requested, we will come to explain anywhere in the country.

• Dismantling and moving

Introducing a titanium alloy with higher corrosion resistance and excellent creep characteristics. There are alloys that can withstand even harsher environments while taking advantage of titanium's properties. If you are having trouble with the durability of titanium materials, please feel free to contact us.

The quality and delivery time of forged products largely depend on the material ingots. We carefully select materials for austenitic, ferritic, martensitic stainless steels, duplex alloys, and tool steels for steelmaking. Based on that, we provide high-quality forged products using state-of-the-art large forging equipment.

• others

We have developed suitable attachments for tasks such as removal, cleaning, and disposal. Furthermore, by working in conjunction with a rotating arm that can rotate 360 degrees, we achieve free operational control of the robotic arm.

**Manufacturing Method of Tantalum Tubes** Tantalum tubes come in welded and seamless types. - Welded tubes are produced by shaping a strip into a tube form and welding the seam using GTAW. - Seamless tubes are made through extrusion, shrinkage, or deep drawing from a plate. **Industries Suitable for Tantalum Tube Adoption** - Tantalum is used in corrosive environments and superconducting fields. It is processed into corrosion-resistant nozzles and electrode tubes. Tantalum is also widely used in the chemical industry for manufacturing parts such as reaction vessels, pipes, condensers, heat exchangers, spiral coils, U-tubes, thermocouple protection tubes, and liquid metal containers and pipes.

In civil engineering and demolition work, you can operate the tongs with the sensation of arm movement. It achieves seamless movement in all directions: forward, backward, left, right, up, and down. When used with a grab, it easily handles heavy objects. It realizes the best combination of high durability and work performance, making it even easier to use than a tilt rotator. Unlike a rotating link, the tongs rotate together, maximizing their efficiency. Additionally, it adopts a pilot proportional control hydraulic system, enhancing user convenience with joystick operation that does not require a controller. Overall, it employs a deliberately high-standard specification with an over-spec design aimed at maximizing durability.
