Laboratory/Research Room Use: Load Holding Without Brakes! Manual/Electric Small Winch
SWM Series / SWE Series
Roll up the work, and it self-locks when the handle is released! No need to release, 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 without releasing the brake, whether in forward or reverse rotation. Its lightweight and compact design allows for space-saving, making it widely adopted and well-received in various fields. With its easy operation, even women and the elderly can lift heavy workpieces, contributing to alleviating labor shortages and improving productivity. In addition to the manual-only models (SWM series), we also offer electric models (SWE series) that can be driven by power tools like drill drivers. The load capacity ranges from 50 kg to 300 kg. Furthermore, we have stainless steel models suitable for clean rooms, as well as aluminum models that achieve further weight reduction in some variants. These winches can be widely used in places without power, for disaster response, 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 institutes, and laboratories. The stainless steel models are not only used in clean rooms but also have numerous applications in marine and shipbuilding industries. Additionally, the aluminum models are lightweight and very convenient for portability. They are also adopted in defense and military-related fields.

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 winds up with a polyester belt instead of wire.
-
There are also organic fiber ropes. For medical devices, there are types that are wound with organic fiber ropes instead of wire. The photo shows a steel material treated with electroless nickel plating.
-
SWE-300-351SS 300 kg load capacity type. Adopted by ship manufacturers. Made of all stainless steel resistant to rust, 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 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.
