New product information: A new modular type of self-locking rack jack has been introduced, featuring a rack movement of 17 mm per one rotation of the input shaft.

This is a reduction device with a new self-locking mechanism (Shoji Lock) that replaces worm gear reducers. It includes a lineup of reduction gears, rack jacks, and winches.

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!

A jack that can lift a load of 50 kN with a light manual operating force (input shaft torque of approximately 11 Nm). It is an applied product of the new self-locking mechanism (Shoji Lock).

This is a jack developed for component maintenance. It is a manual jack equipped with a high-efficiency self-locking mechanism using 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. There are 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 in places without power, as well as for disaster preparedness and energy-saving measures. It can also be used electrically.

• Small baggage lift

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 rise and fall speed due to its high efficiency, making it easy to operate. It is equipped with a unique self-locking mechanism that allows it to hold loads without brakes or stoppers, making it a revolutionary jack. The rated thrust load is 50 kgf, and it can be operated easily by hand. It advances exactly 4 mm per rotation, allowing it to function as a round-number linear jack. With a significant advancement amount, it becomes a highly versatile rack jack and linear actuator.

• Small baggage lift

Compared to screw jacks, this is a hybrid type that allows for high speed and high efficiency, can be operated with commercially available electric tools, 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 general electric tools (drivers/drills). It also comes equipped with a unique self-locking mechanism, allowing it to hold loads without brakes or stoppers, making it a revolutionary jack. Moreover, it is designed to be lightweight and compact while excelling in strength and durability. Additionally, it employs an omnidirectional actuator that can accommodate upward, downward, and lateral movements. It is also suitable for rack-type electric cylinders. This model has a rated thrust load of 100 kgf. *For more details, please visit the official website or feel free to contact us.*

We have introduced our commercial aroma diffuser "Majesta Fragrance" at a karaoke bar located in the city. The model we installed is [MF-02S]. From the moment customers open the door, a gentle fragrance spreads throughout the store, enhancing the atmosphere. We hope to create a memorable store that customers will want to visit again through the use of fragrance. Majesta Fragrance is available for a free trial installation exclusively in the Kanto area. If you are interested in our fragrance services, please feel free to contact us.

We have introduced our Majesta Fragrance in the restrooms of a company located in the city. The model we implemented is the compact-sized MFmini. By adding fragrance to the clean space, we have created an environment where users can spend their time more comfortably. The restroom, which is used daily, has become a more pleasant and high-quality space.

Thank you very much for always using Majesta Fragrance. Our company will be open as usual during the Obon period. Please feel free to contact us for inquiries about scent arrangements or the introduction of commercial aroma diffusers.

High Strength, Low Cost: The Economic Advantages of Carbon Steel Frames Carbon steel is inherently strong, and this high structural strength ensures stable wind resistance while allowing for a simple support structure, reducing the need for extra components. This also lowers the wear rate during transportation, enabling further savings in material costs and installation expenses. Transportation and Construction: Streamlining the Entire Project The advantages of carbon steel frames are also evident in the transportation and construction phases. Standardized designs simplify on-site installation and shorten construction periods. For example, carbon steel frames can be packaged using a combination of wooden sticks and iron ties, improving unloading efficiency and increasing transport volume. This reduces construction time and labor costs, distributing the overall burden of the project across all stages. Technological Innovation: Breakthroughs in Corrosion Resistance With the evolution of material technology, the corrosion treatment of carbon steel frames has also significantly advanced. Grace Solar has adapted to the technological trends in process development, and all current carbon steel frames utilize AlMgZn coating. At the same time, to meet the special requirements of each project, our company offers custom options for hot-dip galvanizing.
