Our products will be exhibited at the "JAPAN INTERNATIONAL BOATSHOW 2015" held at Pacifico Yokohama from today, March 5th, until the 8th (Sunday). We will introduce our unique self-locking feature "shoji-lock" on marine-related products that have seen increased interest in recent years, such as "stainless steel winches" and "rack jacks." The event will also be held on the weekend, so please feel free to stop by. (First venue: Pacifico Yokohama, Booth No. B-19, within the Core Tech Co., Ltd. booth)

A completely new self-locking mechanism with a deceleration function, "Shoji-Lock." Unlike traditional worm gear reducers, it eliminates 'slippage,' offers higher efficiency compared to worms, and allows for a lightweight and compact design, making it suitable for various applications. We have received numerous inquiries from those considering its adoption, asking questions like "Why does it self-lock?" and "What is the mechanism?" Therefore, we have summarized the basic structural diagrams and an overview in an easy-to-understand manner and published them on our website. Additionally, we have newly included examples of special products for various applications (reduction gears, winches, rack jacks). We encourage you to take this opportunity to check them out and consider them. Thank you very much.

We have newly added a motor-mounted version of the self-locking compact winch developed by our company, which has received many requests. Even if the motor brake fails, the winch will self-lock, ensuring safety → achieving a double safety structure. It eliminates the need for brakes when combined with inexpensive motors that do not have a brake function, as the winch's self-locking feature holds the position when movement stops. Additionally, the overall compact design makes it easy to integrate into existing factory equipment. The selection of winches, motors, etc., will vary depending on various conditions (maximum load, frequency of use, etc.). Cleanroom specifications and heat-resistant specifications are also available; please feel free to contact us.

【Product Features】 ◎ Easily jack up 5 tons manually 　→ Input torque of about 11 Nm and excellent operability ◎ Stops immediately when the handle operation is halted, even under load 　→ Self-locking mechanism 　Moreover, it works in both clockwise and counterclockwise directions ◎ Significantly more efficient compared to screw jacks 　→ Approximately 4 times more advantageous in both power and speed ◎ More compact and less cumbersome compared to hydraulic jacks 　→ No natural descent associated with hydraulics ◎ Requires no power source, making it widely usable in mountainous areas and disaster sites 　Also effective as an energy-saving measure This is a revolutionary rack jack with such features. This time, we have prepared a demonstration unit, as seeing is believing! Since there are no other examples, we thought it best for you to see it in person. Please feel free to contact us. Note that quantities are limited, so if you are interested, please act quickly! 【Possible Applications】 ・Various jigs for construction (temporary holding during welding, temporary support during work, etc.) ・Restoration of building tilt (debris processing during liquefaction and other disasters) ・Jigs for large equipment ・Opening and closing agricultural sluices ・Work in areas without power in mountainous regions, etc.

The PDF catalog for the completely new self-locking mechanism "shoji-lock" has been updated. It eliminates the 'slippage' found in traditional worm gear reducers, offers higher efficiency compared to worms, and allows for a lightweight and compact design, making it increasingly adopted in various fields. With an expanded lineup, we have categorized each product into "gear reducers," "linear actuators (rack jacks)," and "winches." You can download it from the top screen of our website (http://www.shoji-lock.jp/) under the news section. We encourage you to take a look and consider it. Thank you very much.

The compact and lightweight winch "S-Winch" series, which incorporates the already well-received new self-locking mechanism (Shoji-Lock), now features a maximum rope pulling force of 300 kgf, as requested by many. 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 in areas without power, as well as for disaster response 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. Furthermore, with a capacity of 300 kg, it can be safely used in caregiving and welfare applications.

We explain product features that are difficult to understand through images and captions in a video. In particular, it's a must-see to watch a 50 kg person actually riding the table lifter and easily operating the handle. Even when the handle is released, it maintains its position and does not budge under a load of 50 kg. You can find it on the homepage (http://www.shoji-lock.jp/) on the top screen under the latest information. Please take a look.

We are Shoji Gear Engineering, developing, manufacturing, and selling inline reducers, winches, and jacks equipped with the new self-locking mechanism "shoji-lock," which allows for a more efficient, lightweight, and compact design than worm reducers. We have received numerous inquiries such as, "How compact is it really?" and "What do you mean by lightweight?" Therefore, we have attached CAD drawings (2D) for all products listed on Ipros. Please feel free to use them during your design process or consideration. Additionally, do not hesitate to contact us for any other inquiries.
