Small winch with load holding function for railway-related applications (SUS/Aluminum available)
No need for brake stoppers! A self-locking winch that can operate without power and can hold loads. Lightweight, smart, and compact with many applications!
We have added a stainless steel type and an aluminum type to our lineup of compact and lightweight winches that already feature the highly praised new self-locking mechanism (Shoji-Lock), in addition to the traditional iron type. Due to the high demand for cleanroom compatibility, we have achieved a compact, lightweight design with a sleek appearance, allowing for space-saving solutions. The winch can rotate in both forward and reverse directions and holds the load in place when stopped. It can be widely used as a disaster response and energy-saving measure without the need for power. Additionally, since it is not a ratchet mechanism, it operates very quietly, making it suitable for nighttime work and environments such as hospitals, research facilities, and laboratories. The SUS version is suitable for use in cleanrooms as well as in marine and ship-related applications. The aluminum version is lightweight and convenient for portability. *For more details, please visit our official website or feel free to contact us.*

Detailed information
-
Made of aluminum with a proven track record in semiconductor devices. There is a track record of semiconductor devices made from aluminum material (A7075). There is also a type that uses a polyester belt instead of wire for winding.
-
There are also organic fiber ropes. For medical devices, there are types that are wound with organic fiber ropes instead of wires. The photo shows a steel product that has been treated with electroless nickel plating, finished at a low cost.

Company information
The load-holding function equipped reduction mechanism (shoji-lock) has been developing applied products such as winches and rack jacks since the early 2000s. Steady sales activities have borne fruit, and it has begun to be adopted for various applications. Unlike conventional worm reduction gears with self-locking functions where the input and output shafts are orthogonal, this mechanism has them aligned in a straight line (inline), allowing for a compact design and space-saving, which has received high praise, resulting in a diverse range of practical examples. (Patents have been obtained in Japan, the United States, the EU (Germany, France, the UK), China, South Korea, and Taiwan.) Furthermore, starting in April 2023, we launched a new business for overseas parts procurement, beginning with Vietnam. Currently, a majority of our parts are also procured overseas, and we hope to leverage our achievements and network to assist companies struggling with cost reduction in parts procurement.
