Hitherto, this type of lifting belt has been disclosed in U.S. Patent No. 2903291, Japanese Utility Model Publication No. 15801/1983, and Japanese Utility Model Application Publication No. 1989-1580.
Some of these are disclosed in Japanese Utility Model Publication No. 43878, Japanese Utility Model Application Publication No. 53-132174, etc.
これらの吊上帯の芯としては、無端状の厚手の

している。 As the core of these suspension bands, an endless thick fabric is used, or a thin fabric wound several times to form an endless fabric is used. and,
This core is wrapped in a (planar) outer sheath, and then the overlapping peripheral edges of the outer sheath and the core are sewn together over their entire length to integrate the two parts. This prevents the core portion and the outer covering from shifting.

ものとしていた。
As mentioned above, in conventional lifting straps, the outer sheath that wraps around the entire core is sewn to the core over its entire length, so the difference between the outer sheath and the core that occurs when the lifting strap is used The area affected by the misalignment extends over the entire length of the jacket and core, and this sewn portion was often damaged. Further, since the surface of the outer covering is relatively smooth, the transported object easily slides on the lifting belt, making it difficult to stably hold the transported object during work.
そこで、本発明では、外被を筒状のものとし、

吊上帯を提供することを目的とする。 Therefore, in the present invention, the outer cover is made into a cylindrical shape,
A belt-like fabric is wound around this cylinder to form a core material, and folds are actively formed on the surface of the outer jacket to increase the frictional force between the material and the transported object, resulting in strong strength. An object of the present invention is to provide an endless lifting belt for transportation that can securely hold a transported object.

The endless lifting belt for transportation of the present invention has a core formed by winding a thin belt-shaped fabric in a skein-like manner through a cylindrical outer cover, and the total length of the belt is longer than the total length of the core. The core is entirely covered with the formed cylindrical jacket so that a large number of folds are formed on the surface of the jacket to form an endless band, and the inner periphery of the central part of the band is By overlapping the surfaces and sewing them together, a hanging ring for hanging on a crane or the like is formed at both ends of the band.

As mentioned above, since the total length of the cylindrical outer sheath is longer than the total length of the core, when an endless lifting band is formed, many folds will be formed on the surface of the outer sheath, which will hold the transported object. When this happens, the frictional force between the outer covering surface and the transported object becomes large. In addition, since the outer sheath and core are only sewn together at the center of each, the other parts are sewn to each other (separately) to withstand the various forces that are applied to the endless sling. It can assume a state of stress.

芯Ｂが硬くならないように注意する必要がある。 A woven fabric 1 made of synthetic fibers or the like is woven into a belt shape (as shown in the cross-sectional views in FIGS. 3 and 4), and is passed through an outer sheath C made of nylon, synthetic fibers, or the like in a cylindrical shape (as shown in the cross-sectional views of FIGS. 3 and 4). The core B is formed by winding the core B in a skein-like manner (as shown in Figure 1), with the inner end 1a at the beginning of winding and the outer end 1b at the end of winding being staggered from each other. At this time, weaving yarns of different colors (for example, red or the like, commonly known as signal yarns) are used approximately in the center of the width direction of the core B so that the limit of the working load can be indicated. In addition, when forming the belt-shaped fabric 1 using a known double weave or triple weave, be careful not to make the core B hard by limiting the number of windings of the skein to 2, 3, etc. There is a need.

3a to form an endless suspension band A. The sewing thread 4 is joined in an M-shape at a portion close to the hanging rings 3, 3a, and this is an example of preventing a portion from fraying easily.

A reinforcing cylinder D formed into a cylinder shape from the same material as the core B
It is possible to prevent damage to the endless suspension band A by attaching the suspension ring 3, 3a, the corner of the transported object, the portion that comes into contact with a convex portion, etc.

The present invention has a structure in which pleats are formed on the surface of the outer jacket of the endless lifting belt to increase the frictional force at the contact portion between the transported object carried by the endless lifting belt and the outer jacket. Not only when lifting and transporting objects, but also when lifting and transporting multiple bundles of metal pipes, pipes, etc., the transported objects will not slide against the endless lifting belt. ,
Stable transportation work can be performed. Further, since some of the external vibrations are absorbed by the folds, it is possible to prevent the conveyed object from shaking due to the vibrations.
