Compared to screw jacks, this is a hybrid type that can be operated with commercially available electric tools due to its high speed and efficiency, and can also be operated manually by attaching a handle.
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. Therefore, it can be operated quickly with standard electric tools (drivers/drills). Equipped with a unique self-locking mechanism, this revolutionary jack can hold loads without brakes or stoppers. Additionally, it boasts excellent strength and durability while being lightweight and compact in design. It also employs an omnidirectional actuator that can accommodate upward, downward, and lateral movements. It is ideal for rack-type electric cylinders, with a rated thrust load of 400 kgf and a reduction ratio of 78. *For more details, please visit the official website or feel free to contact us.

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.
