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.

Applications/Examples of results
It has been adopted as a tool for replacing transmission line tower components. Since the work is in mountainous areas, it can be easily manually lifted with a 3-ton jack even without a power source. Made of aluminum, it is relatively light (about 36 kg) and can be carried to the site on your back, among many other advantages.

Company information
The load-holding function equipped reduction mechanism (shoji-lock) has been developed for application products such as winches and rack jacks since the early 2000s. Steady sales activities have borne fruit, and it has begun to be adopted for various applications. Unlike conventional worm reduction gears with self-locking functions where the input and output shafts are orthogonal, our design features them in a straight line (inline), allowing for a compact design and space-saving, which has received high praise and resulted in a diverse range of practical examples. (Patents have been obtained in Japan, the United States, the EU (Germany, France, the UK), China, South Korea, and Taiwan.) Furthermore, starting in April 2023, we launched a new overseas parts procurement business, beginning with Vietnam. Currently, a majority of our parts are procured overseas, and leveraging our achievements and network, we aim to assist companies struggling with cost reduction in parts procurement.
