The "Super Jack System" supports safe and reliable construction based on a wealth of experience in jack construction, including method examination, rental and leasing of jack equipment, manufacturing and sales, and execution and operation. The Super Jack is slim and quiet yet powerful, safe, and environmentally conscious, making it a reliable performer on site. 【Features】 ■ Suitable for narrow spaces where heavy machinery cannot be used ■ Quiet and environmentally friendly ■ Capable of handling high elevations ■ Able to manage heavy loads *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce a case where our "Super Jack System" for bearing replacement was adopted for a highway project. Traditionally, the operation of jacking up the superstructure during bearing replacement was done manually. This system allows one operator to control all hydraulic jacks, enabling construction without the need to assign personnel to each jack. In this project, we implemented the bearing replacement work by centrally and automatically controlling 26 hydraulic jacks. Additionally, it has been highly evaluated for its effectiveness and has been adopted in other projects as well. 【Case Overview】 <Challenges> ■ Traditionally, the operation of jacking up the superstructure during bearing replacement was done manually. <Solution> ■ One operator can control all hydraulic jacks, allowing construction without the need to assign personnel to each jack. ■ Adjustment work using repair materials is also easy. ■ It is possible to save data on the load and displacement applied to the actual bearing. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of our company's "Biomass Silo Slip Form Method." This method integrates the formwork and working floor, allowing them to be raised by jacks, which eliminates the need for scaffolding and the formwork assembly process, enabling continuous concrete pouring. For the construction of four silos, we planned to manufacture the slip form device (SF device) so that it can be divided, thereby shortening the replacement process. (Steel formwork and connection bolts will be newly used for each replacement of the SF device.) 【Case Overview】 ■ Location: Construction of four silos ■ Details - Planned to manufacture the slip form device (SF device) to allow for division and shorten the replacement process. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce examples of the adoption of our "Nice Pole/Slip Form Method." In the renovation project (demolition and new construction) of an existing baseball stadium by Kawasaki City, a protective net pole was installed above the stands, reaching a height of approximately 30 meters above ground. This project is a two-phase construction, which includes the manufacturing and installation of the poles and the stretching of the nets. Additionally, in the construction of an RC chimney at a coal-fired power plant, we adopted the "Slip Form Method," which is a safe and labor-saving method that allows for continuous construction of concrete walls. The chimney has a height of 165 meters, and the structure was constructed at a pouring height of approximately 2 meters per day. 【Case Overview】 <Nice Pole> ■Location: Kanagawa Prefecture, Todoroki Hardball Baseball Stadium ■Details: Protective net pole installed above the stands, with a height of approximately 30 meters above ground. <Slip Form Method> ■Location: Yamaguchi Prefecture, T Power Plant Chimney ■Details: The chimney height is 165 meters, constructed at a pouring height of approximately 2 meters per day. *For more details, please refer to the PDF document or feel free to contact us.
