The second volume of the case studies for the new self-locking deceleration mechanism "shoji-lock" has been completed.

庄司歯車エンジニアリング 庄司歯車エンジニアリング
- Small winches have been adopted in shops and museums in Ginza. = They have received positive feedback for their design, being compact and unobtrusive in black. = They are also praised for being easy to operate by ourselves, among other things. Instead of a worm gear, we have developed a completely new inline reducer that self-locks when motion stops, as well as a small winch that maintains position when the handle is stopped in both forward and reverse rotation instead of using a ratchet. Due to the positive reception and increased achievements in various fields, we have created a second edition this time. Please download it and consider it!

Jack 50KN manual/electric rack jack with self-locking function

A jack that can lift a load of 50 kN with a light manual operating force (input shaft torque of approximately 11 Nm). This is an application product of the new self-locking mechanism (Shoji Lock).

This is a jack developed for component maintenance. It is a manual jack with a high-efficiency self-locking mechanism utilizing spur gears, featuring the Shoji lock. The main body weighs 36 kg and is made of aluminum, designed with a focus on lightweight and manual operability. It has two input shafts (high/low), allowing for easy switching between quickly turning the handle when there is no load and applying force when there is a load, simply by changing the insertion of the handle. It can be widely used for work in areas without power, as well as for disaster preparedness and energy-saving measures. It can also be used electrically.

[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.
