This is a compact and lightweight winch equipped with our 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, regardless of the 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-compatible (SWE series) models. The load capacity ranges from 50 kg to 300 kg. Furthermore, we have stainless steel models suitable for clean rooms and vacuum equipment, as well as aluminum models that achieve further weight reduction in some variants. These winches can be widely used for work in locations without power, disaster response, energy-saving measures, defense and military applications, and explosion-proof measures. Since it is not a ratchet, it operates very quietly, making it suitable for nighttime work and environments such as hospitals, research institutes, 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.

弊社開発のセルフロック機構(Shoji-Lock)を内蔵した小型インライン減速機です。 例えば装置の昇降や回転、傾動時の途中で動きを止めても荷重を保持できる為、止めた位置で実験したい、作業したいなどという要求に好適です。 もうひとつの特長として、従来のセルフロック機能を有するウォーム減速機は入力軸と出力軸が直交しているためかなり大きなスペースが必要となるのに対し、入出力軸が一直線上（インライン）にあるため、軽量でスマート・コンパクトに設計ができ、様々な装置内に組み込みやすくなっております。 ラインナップも出力軸トルクや減速比によって各機種選択可能。 耐出力軸トルク５～１００ｋｇｍ（荷重×トルクアーム）までご用意。 一部製品ではクリーンルーム対応としてオールステンレス製もラインナップしております。 基本は錆に強い黒色テフロンコーティングを施しています。 また、災害時に電源が無くても駆動・荷重保持が可能です。 防衛・軍事関連、プラント関連、半導体製造装置、自動車組立ライン、装置蓋開閉など様々な所に機械要素として導入していただいております。

This is a compact and lightweight rack-type jack (linear actuator) equipped with our company's self-locking mechanism (Shoji-Lock). It holds the load at the stopped position while raising and lowering the workpiece. Additionally, it can be restarted from any position without releasing the brake, whether in the upward or downward direction. Due to its lightweight and compact design, it saves space and has been adopted and well-received in various fields. Unlike conventional screw jacks, the rack type offers overwhelmingly faster ascent and descent speeds, characterized by its high efficiency and ease of operation. In addition to the manual-only (SLM series) models, there are also electric models (SLE series) that can be driven by a power tool drill driver. The surface features a standard black Teflon coating that is resistant to rust. It can be widely used for disaster preparedness, energy-saving measures, and defense/military applications. It is also suitable for universities, research institutes, testing facilities, and explosion-proof measures. As shown in the photos and videos, when mounted on a lab jack or table lifter, it can hold its position while loaded, and by turning the handle again, it can resume raising and lowering without any motion delay. It is compatible with commercially available round rack rods (manufactured by KHK). (Rack rods are not included.)

Are you facing any of these issues with parts procurement? "The local factory I used to rely on for cheap orders has gone out of business... When I got a quote from another company, they offered me a price more than double." "I was sourcing parts from China to reduce costs, but... rising labor costs have eliminated any cost advantages." All of these issues can be resolved through parts procurement in Vietnam and other Southeast Asian regions. Our small-scale manufacturing company has also struggled for many years with reducing parts procurement costs and has faced difficulties in making profits. As a solution, we started working with a Vietnamese company. There were no issues with quality, cost, or delivery time, and above all, we felt a strong sense of "motivation," "positivity," and "integrity," which led us to request various parts from them. Now, we have switched about 60% of our total parts procurement to Vietnam and other overseas sources. We hope to leverage this experience and network to assist other companies facing similar challenges.

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.

Unlike conventional screw jacks, this rack-type jack features an overwhelmingly fast rise and fall speed due to its high efficiency, making it easy to operate. It is also equipped with a unique self-locking mechanism that allows it to hold loads without brakes or stoppers, making it a groundbreaking jack. With a rated thrust load of 50 kgf, it can be operated manually with ease, advancing exactly 4 mm per rotation, which also makes it a round-number linear jack. Its significant advancement makes it a highly versatile rack jack and linear actuator.

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.

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!
