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

This is the second product that combines a modular type jack with a reducer equipped with a new self-locking mechanism that does not use the conventional self-locking function's worm gear at all. The input shaft torque is light at 1.01 kgm at 100K, and a fast advance of 17 mm per rotation has been achieved. We propose this to customers who want to lift quickly with a small force and aim for space-saving in various factory production lines. Additionally, it is also possible to attach a guide rod (twin shaft type).

The new compact and lightweight winch "S-Winch" series, which incorporates the already popular new self-locking mechanism (Shoji-Lock), now features a built-in pulley model that has been highly requested. Originally designed to be compact, lightweight, and with a sleek appearance, the integration of the pulley further enhances space-saving capabilities. It supports a maximum load torque of 5 kgm, achieving light handle operation (approximately 6 kg when the handle diameter is 120 mm). It rotates in both forward and reverse directions and locks in place when stopped. It can be widely used in places 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.
