Small winch with load holding function for railway-related applications (with SUS/aluminum)
No need for brakes or stoppers! A self-locking winch that can operate without power and can hold loads. Lightweight, smart, and compact with many applications!
We have already received great feedback on our new self-locking mechanism (Shoji-Lock) incorporated into a compact and lightweight winch, which now comes in stainless steel and aluminum types in addition to the traditional iron model. Due to high demand for clean room 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, it operates very quietly, making it suitable for nighttime work and environments such as hospitals, research facilities, and laboratories. The SUS model can be used not only in clean rooms but also in marine and ship applications. The aluminum model is lightweight, making it 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 using 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 undergone electroless nickel plating, finished at a low cost.

Company information
The load-holding function equipped reduction mechanism (shoji-lock) has been developed for application 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, our design features them in a straight line (inline), allowing for a compact design and space-saving, which has received high praise and resulted 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 overseas parts procurement business, beginning with Vietnam. Currently, a majority of our parts are procured overseas, and leveraging our achievements and network, we aim to assist companies struggling with cost reduction in parts procurement.
