[Case Study] Hard Court at a Certain Tennis School in Kanto

All hard courts (6 surfaces) in the school were cleaned over 6 days! A case where the original color became visible.

A certain tennis school management company was troubled by moss adhering to the accumulated dirt on the hard courts (concrete painted floors) within the school. When it rained, the surface became slippery due to the moss, posing a risk of students slipping and falling. In response, our company used the 'HOTJEBLO Fujiyama R2' to clean all six hard courts over a period of six days. The original colors painted in red and green became visible again, and the management company was very pleased. Additionally, the risk of injury was reduced, and we received high praise from the students of the school. 【Case Summary】 ■ Equipment Used: HOTJEBLO Fujiyama R2 ■ Issues - Moss adhered to the accumulated dirt on the hard courts (concrete painted floors) within the school. - When it rained, the surface became slippery due to the moss, posing a risk of students slipping and falling. ■ Results - The original colors painted in red and green became visible again, which was greatly appreciated. - The risk of injury was reduced, and we received high praise from the students of the school. *For more details, please refer to the PDF document or feel free to contact us.

• High pressure cleaner

Restoration and cleaning of athletic fields and outdoor sports facilities can be done! A special cleaning machine that can perform 'hot water high-pressure cleaning' and 'wastewater recovery' simultaneously! *Registered with NETIS.

The "Hot Jebro Fujiyama R2" automatically generates high-pressure water injection of up to 20MPa (approximately 200kgf/cm²) and utilizes hot water at a maximum temperature of 80°C for cleaning, while simultaneously enabling the recovery and treatment of wastewater. It is an integrated cleaning system that combines multifunctionality into a single unit, featuring a hot water high-pressure cleaning and suction device. Please consider this method, which enables speedy and smart construction, achieving overwhelming "shortened construction time" and "reduced manpower." **Features** - Integrated cleaning machine for "hot water generation," "high-pressure cleaning," and "wastewater suction" - Remarkable cleaning effectiveness - Significant efficiency improvement - Reduces two different tasks into one process - Space-saving, engine-driven design *For more details, please refer to the catalog or feel free to contact us. You can also view before-and-after cleaning videos from the link below!*

• High pressure cleaner

Overwhelming reduction in work time! By eliminating wastewater discharge and enabling simultaneous cleaning and wastewater collection, it is possible to centralize the process.

We have verified how the "Hot Jeblo Method" is superior to conventional high-pressure washing. Conventional high-pressure washing requires protective measures against splatter and post-treatment of wastewater, but with the "Hot Jeblo Method," there is no wastewater runoff, allowing for the integration of washing and simultaneous wastewater collection. The advantage of simultaneous washing and wastewater collection is a significant reduction in work time. We have a verification video, so please take a look. 【What is the HOTJEBLO Cleaning System?】 ■ HOT (hot water device) + JET (high-pressure pump) + BLOWER (vacuum) ■ Integration of high-pressure washer, hot water device, and vacuum ■ Simultaneous processing of washing, rinsing, and wastewater treatment in three steps ■ Significant reduction in work time and labor *For more details, please refer to the PDF document or feel free to contact us.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

Last month, we held a spring safety conference hosted by our company. We have compiled the details and atmosphere of the day into a PDF. We would appreciate it if you could take a moment to read it.
