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

庄司歯車エンジニアリング 庄司歯車エンジニアリング
This is the second product that combines a modular jack with a gearbox featuring a new self-locking mechanism that does not use the conventional self-locking worm gear at all. The input shaft torque is light at 1.01 kgm at 100K, and a fast advancement of 17 mm per rotation has been achieved. We propose this to customers who want to lift quickly with minimal force and aim for space-saving in various factory production lines. Additionally, it is possible to attach guide rods (twin shaft type).

We will provide you with a case study collection: How to use the new self-locking mechanism, Shoji Lock?

This is a reduction device with a new self-locking mechanism (Shoji Lock) that replaces worm gear reducers. The lineup includes 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!

Jack 50KN manual/electric rack jack with self-locking function

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.
