[For logistics] Holds load without brakes! Compact winch

The work is wound up, and it self-locks when the handle is released! No need to release, 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 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. In addition to the manual-only (SWM series) models, we also offer electric tool drill driver-driven (SWE series) models. The load capacity ranges from 50 kg to 300 kg. Furthermore, we have stainless steel models compatible with clean rooms, as well as aluminum models that achieve further weight reduction in some variants. They can be widely used in locations 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 numerous applications in marine and ship-related fields. The aluminum models are very convenient for portability due to their lightweight design. They are also adopted in defense and military-related applications.
