Wire Rope
Although Wire Rope used under various conditions can be found in many different places, people do not think very much about Wire Rope and may not think that they come in different shapes and categories. For most of the people, they look the same to each other. However, they are not all the same, and you must choose the right one for each use. In order to choose a wire rope that suits your needs, you must have thorough understanding of its structure and characteristics.
For the use with Crane
Recent rationalization of load carriage work has been increasing crane use. In order to adapt to each use, crane structures and functions have diversified.
Many think that rope is an expendable part of crane and tend to handle them rather recklessly. However, a handler's lack of knowledge in rope and such reckless handling have often led to a serious disaster.
With growing diversity of crane functions, demands for characteristics of wire rope are rising to meet each purpose of use.
For the use with Elevators
Recently, elevators, such as super high-speed elevators in high-rise buildings like those in Landmark Tower, Tokyo Metropolitan Government Buildings, and TAIPEI 101 (in Taiwan), have become indispensable in our daily lives. Elevators are also installed in small-scale condominiums and personal homes, and the number is increasing. However, rope used in those elevators involves human lives: thus the building-cord regulates its classification and standards.
For the use in Forestry and Fisheries
Due to the regulation on logging to alleviate environmental destruction, cableway used in forestry has been gradually replaced with helicopter yarding. In addition, log imports have slowed down the domestic industry, greatly reducing a demand for rope. However, a great number of ropes are still used as wire to carry logs.
Rope Sling
Rope Sling is used to lift materials. It is a wire produced by a special processing method. An aluminum alloy heterogeneous tube is attached to the connecting parts of a rope and is compressed from the outside. The plastic deformation gives a strong binding power to the wire.
For the use with Cableway
Overhead cableway has a very long history. We do not have an accurate record, but it has been used since 600 years ago in back-countries in mountain areas. They were the public transportation in such places like sheer cliffs, where normal people cannot walk. Examples are "Kago-Watashi" in Hida, "Yaen-Watashi" in Kishu, Yoshinosan, Yamato, Shinshu-kiso and "Tsuna-Watari" in Shikoku. In China and India, cableway was already in use 1,000 years ago to carry materials, as is recorded.
At present, cableway in Japan is one transportation industry, which 470 million people use per year. They are indispensable for skiers and sightseers among mountain sites. Above all, ski lift and cable car have the greatest number of installation in the world. We supply wire rope to many companies for their cableway facilities.
