The work is wound up, and it self-locks in the position where the handle is released! No need to unlock, and it can restart in both forward and reverse rotation from the stopped position! Lightweight and compact with many applications!
This is a compact and lightweight winch equipped with our company's self-locking mechanism (Shoji-Lock). It holds the load at the position where the workpiece is lifted. Additionally, it can be restarted from any position in both forward and reverse rotation without releasing the brake. Its lightweight and compact design allows for space-saving, and it has been adopted and well-received in various fields. In addition to the manual-only (SWM series) models, we also offer electric tool drill driver-compatible (SWE series) models. The load capacity ranges from 50 kg to 300 kg. Furthermore, we have some models made of stainless steel suitable for clean rooms, as well as aluminum models that achieve further weight reduction. They can be widely used in places without power, for disaster response, explosion prevention, energy saving measures, and in defense and military applications. Since it is not a ratchet, it operates very quietly, making it suitable for nighttime work and for use in hospitals, research facilities, and laboratories. The stainless steel models are not only used in clean rooms but also have many applications in marine and ship-related industries. The aluminum models are very convenient for portability due to their lightweight design. They are also used in defense and military applications.

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 for winding instead of wire.
-
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.
-
SWE-300-351SS 300 kg load capacity type. Adopted by ship manufacturers. Made of rust-resistant all stainless steel, it is designed for lifting with a rechargeable drill driver (high torque specification) on board without a power supply.
-
SWE300L-351 Long bobbin type with a load capacity of 300 kg. Longer wire winding length than the standard type. Adopted by ship manufacturers. Available in stainless steel. The photo shows a steel version with black Teflon coating.

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.
