New Product Information: Manual Small Winch - New Pulley Drum Type Now Available in the Self-Locking Winch Series

庄司歯車エンジニアリング 庄司歯車エンジニアリング
The new compact and lightweight winch "S-Winch" series, which incorporates the already well-received new self-locking mechanism (Shoji-Lock), now features an internal pulley model that has been highly requested. Originally designed to be compact, lightweight, and with a sleek appearance, the addition of the internal pulley further enhances space-saving capabilities. It supports a maximum load torque of 5 kgm, achieving a light handle operation force (approximately 6 kg with a handle diameter of 120 mm). It can rotate in both forward and reverse directions and locks in place when stopped. It can be widely used in locations without power, as well as for disaster preparedness and energy-saving measures. Additionally, since it is not a ratchet, it operates very quietly, making it suitable for nighttime work and environments such as hospitals and stage equipment. As an application, a chain sprocket drum type is also possible.

We will provide you with a case study collection: How to use the new self-locking mechanism, Shoji Lock?

This is a reduction device with a new self-locking mechanism (Shoji Lock) that replaces worm gear reducers. The lineup includes reduction gears, rack jacks, and winches.

Compared to conventional worm gear reducers, our compact design and high efficiency have received positive feedback. However, we also hear many voices expressing resistance or anxiety towards new products, as well as those who prefer to stick with traditional options. We encourage both those who are hesitant and those who love new things to take a look at our case studies and consider them. Conversely, we welcome valuable suggestions on potential applications as well!

[Stainless Steel Specification] Small Manual Self-Locking Winch 50kg

A stainless steel type of winch with a compact, lightweight, and sleek appearance has been introduced, featuring a self-locking function that can hold the load even when the operator's hands are off during operation.

The compact and lightweight winch "S-Winch," equipped with the already well-received new self-locking mechanism (Shoji-Lock), now comes in a rust-resistant stainless steel type. Due to high demand for compatibility with clean rooms, we have prepared a model with a maximum rope pulling force of 50 kgf. It achieves a compact and lightweight design with a sleek appearance, allowing for space-saving. It can rotate in both forward and reverse directions and locks in place when stopped. It can be widely used as a disaster response and energy-saving measure without the need for a power source. Additionally, since it is not a ratchet type, it can be used in various locations and operates very quietly, making it suitable for nighttime work and hospitals. Being made entirely of stainless steel, it can be used not only in clean rooms but also in marine and ship-related applications.
