High performance condensed into a lightweight and compact design! A jack that achieves maximum weight reduction while ensuring strength.
The "screw jack" integrates a reducer and a screw shaft. It is ideal not only for lifting and lowering but also for pushing, pulling, and tilting. With a self-locking feature (fall prevention), it can maintain its position even without brakes. (Note: In some cases, it may not be able to hold its position.) It uses high-precision manufactured gears, achieving silent operation and long lifespan. It is designed to be compact and lightweight. >>> Do you have any of these concerns? <<< /By replacing it with a jack and electrifying it, all issues can be resolved/ Oil leaks, vibrations, and maintenance work caused by hydraulic products Preparation of auxiliary equipment (compressors, hoses, piping) due to pneumatic and hydraulic products Insufficient power due to pneumatic equipment, etc. ■-----Custom-made products available-----■ Please consult with our sales representative. For example… - I want to use it in high (low) temperature environments - I want to use it in food machinery - I also want an adapter for the motor - I want to use it outdoors, etc. ■-----We will bring samples!-----■ If you are interested, please contact us using the information below or call our sales office (TEL 03-6363-3163). *For more details, please refer to the PDF document or feel free to contact us.
