Faster and more efficient compared to screw jacks. It can be operated quickly and lightly by hand, has a compact design, and can hold loads without the need for a stopper, making it highly safe.
Unlike conventional screw jacks, this rack-type jack features an overwhelmingly fast ascent and descent 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 revolutionary jack. It can be easily operated manually with a rated thrust load of 400 kgf.

Company information
The load-holding function equipped reduction mechanism (shoji-lock) has been developing applied 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, this mechanism has them aligned in a straight line (inline), allowing for a compact design and space-saving, which has received high praise, resulting 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 business for overseas parts procurement, beginning with Vietnam. Currently, a majority of our parts are also procured overseas, and we hope to leverage our achievements and network to assist companies struggling with cost reduction in parts procurement.
