We would like to introduce the "Forestry Wire Rope" handled by Naniwa Seiko Co., Ltd. The "Mega Rope" excels in compressive strength (crush resistance), has less elongation compared to natural fiber cores, and is advantageous in terms of internal corrosion progression due to its lack of water absorption. Additionally, we also offer "6×7" and "6×19" options. Please feel free to contact us for inquiries. 【Mega Rope Features】 ■ Excellent compressive strength (crush resistance) ■ Less elongation compared to natural fiber cores ■ Advantageous in terms of internal corrosion progression due to lack of water absorption ■ Structurally, the upper strands are relatively thicker ■ Excellent wear resistance *For more details, please refer to the PDF document or feel free to contact us.

"Nack Force" is a non-rotating rope designed with consideration for entanglement between wire ropes during work, as well as for rotational stability, safety, and work efficiency when used in a single lift. By adjusting the length of the strands and reducing the number of strands, the distance between the center of the rope and the center of the strands is shortened, enhancing the structural non-rotational properties of the product. Thanks to special processing, the surface of the rope is smooth, resulting in a larger contact area with drums, sheaves, etc. The upper layer wires are relatively thick, providing excellent wear resistance. [Features] ■ Smooth surface of the rope due to special processing ■ Large contact area with drums, sheaves, etc. ■ Relatively thick upper layer wires ■ Excellent wear resistance *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Low-Twist (Long Pitch) Rope" handled by Naniwa Seiko Co., Ltd. Unlike general ropes, we have reduced the torque coefficient by making the length of the rope and strands a special specification. Our company manufactures "Long Pitch," "Flex," "Hyper," and "Kalaman." 【Features】 ■ Flex Rope - By increasing the length, we suppress the inherent twist generated by the rope's structure. - It is less likely to tangle during work. ■ Hyper Rope - The direction of the wire rope core is opposite to the direction of the rope twist. - This structure reduces the torque coefficient and minimizes tangling during work. *For more details, please refer to the PDF document or feel free to contact us.

"Power Rope" is a wire rope with a special shape that prioritizes wear resistance. The smooth surface of the wire increases the contact area with sheaves and other components, making it structurally resistant to wear. Additionally, since each wire makes surface contact, internal wear is reduced. Moreover, the wires are less likely to deform due to floating or whipping, and the effective cross-sectional area is larger compared to conventional ropes of the same construction, resulting in higher breaking strength. [Features] - The wire surface is smooth, increasing the contact area with sheaves and other components. - Resistant to wear. - Internal wear is reduced due to surface contact between each wire. - Less likely to deform due to floating or whipping. - Higher breaking strength due to increased effective cross-sectional area. *For more details, please refer to the PDF document or feel free to contact us.*

We would like to introduce the "Natural Core Rope" handled by Naniwa Seiko Co., Ltd. It achieves approximately 40% more softness compared to 6×24 O/O Type A and about 30% more softness compared to 6×37 O/O Type A, while being supple and hard. Additionally, we offer the "NACK-LOK," which is a compression eye made using this product and an aluminum alloy sleeve with corrosion resistance. 【Features of Natural Core Rope】 ■ Supple & Hard ■ Achieves softness ■ The restricted working load used with lifting slings can be used as is *For more details, please refer to the PDF document or feel free to contact us.

Ropes are used in various industrial machinery beyond parallel applications. At Naniwa Seiko Co., we have developed a high-quality, abrasion-resistant deformed wire strand rope called "Power Rope" based on customer feedback, and it has received positive acclaim.

• Crane and others

In recent years, mobile cranes have been increasing in height, making entanglement during multi-point lifting more likely to occur. Naniwa Seiko has developed a flame-retardant "Flex Rope" to enhance the work efficiency of our customers, which has been well received.

• Crane and others

In high-lift crane operations, entanglement with multiple slings and the rotation of loads with a single sling drastically reduce work efficiency. Naniwa Seiko has developed the non-rotational 4-strand rope "Nack Force," which prioritizes this issue and has received positive feedback.
