A cart-mounted motor for tasks such as pipe cleaning and pipe washing. High-pressure cleaners and other equipment can be attached to the cart for use in pipe cleaning and washing operations.

In Japan, the infrastructure such as piping that was developed after the period of rapid economic growth is aging one after another, and the maintenance and management of these pipes has become a significant issue. Recently, with an increase in accidents such as water pipe bursts due to pipe damage, regular maintenance of water supply and drainage pipes has become necessary to avoid damage from corrosion, cracks, and wear. The complex and winding piping makes it difficult for humans to perform maintenance work, leading to the need for maintenance robots that can operate remotely and autonomously within the pipes. Many maintenance robots, such as pipe inspection robots equipped with cameras for pipe inspection and robots for pipe cleaning and washing, are being manufactured. 【Features】 ■ Capable of mounting encoders for speed control and position control【Special trolley applications】 ■ Coreless structure allows for high-speed rotation with no cogging ■ High efficiency motor achieved by using powerful permanent magnets ■ Motor rotation speed detected from output by driver unit

Our company's CP motors do not use electromagnetic steel plates; instead, they utilize aluminum. Since aluminum has a significantly lower specific gravity compared to electromagnetic steel plates, using aluminum contributes to further weight reduction of our motors. However, aluminum is corrosive, so proper surface treatment is necessary. By the way, did you know that there are many types of aluminum, including bright aluminum alloy plates, high-gloss aluminum alloy plates, high-strength aluminum alloy plates, thick aluminum alloy plates, and high-precision thick aluminum alloy plates? To prioritize cost advantages, we use ADC12 (for mold applications) and A5052 as standard aluminum, which are easy to machine. Aluminum is used in various aspects of daily life, but even when simply referred to as aluminum, there are many different types. Specifically, there is pure aluminum, which is over 99% aluminum, and aluminum alloys, which have various metallic elements added to change their properties. Generally, the "aluminum" commonly used is mostly aluminum alloy. For more details, please contact us or download the catalog.

Fukuda Co., Ltd. has been pursuing leak detection for 60 years and is committed to advancing the future of leak testing. 【 Supporting Various Leak Tests: Air Leak Test / Gas Leak Test (Hydrogen Gas, Helium Gas) 】 We develop, manufacture, and sell leak testing equipment to inspect airtightness and sealing properties. We will propose the appropriate testers and devices for each inspection target. 【 Target Industries and Examples of Inspection Targets 】 - Automotive Industry: Engines, FC components, valves and piping, various parts - Electronic Components Industry: Smartphones, keyless switches, various small sensors - Pharmaceuticals / Food / Cosmetics Industry: Bottle containers, syringes, vials, eye drop containers, pillow packaging, PTP packaging We will propose the most suitable leak testers for each industry. 【 ISO Certification 】JIS Q 9001:2015 (ISO 9001:2015)

In civil engineering sites, the use of sheet piling methods is essential for safely utilizing the site, including temporary roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates have been widely used, but due to their weight, they can be cumbersome to transport, install, and remove. Hyper CLT sheet piles are civil engineering materials made from wooden CLT for civil use. The 5×10 panel weighs approximately 230 kg, and the 5×20 panel weighs about 460 kg, making them lightweight and easy to handle with small machinery, contributing to reduced burdens during installation and improved work efficiency. They can be utilized in a wide range of civil engineering sites for measures against muddy conditions, ground protection, heavy machinery scaffolding, and ensuring pedestrian pathways. As a registered technology under the Ministry of Land, Infrastructure, Transport and Tourism NETIS "TH-250021-A," it is also recommended as a material for innovative ideas, safety measures, and environmental considerations in public works.

Fukuda's new flagship model. - Masterless type (FLA-0200 series) - General type (FLA-0201 series) Two models of air leak testers. With the mastering correction function, high-precision measurements can be achieved in a short time. Please take a look at the catalog.

Fukuda Co., Ltd., which develops, manufactures, and sells leak testing equipment to inspect airtightness and sealing performance, provides a technical document that clearly explains the methods and theories of airtight testing, titled "Technical Manual." We are offering it as a PDF file. Please take this opportunity to download and view it!

What is an Air Leak Tester? An "Air Leak Tester" is a device that pressurizes the inside (or outside) of a sealed workpiece with air and determines the presence of leaks based on pressure changes. When a master with no leaks and a workpiece with leaks are pressurized, the pressure on the workpiece side decreases, creating a pressure difference between the two. By measuring this pressure difference, the presence of leaks can be determined. Generally, differential pressure air leak testing is widely used, but Fukuda also offers products that utilize direct pressure leak testing and flow meters according to the leak rate, in addition to differential pressure leak testers. Since the air leak tester uses air as the measurement medium, it incurs no running costs and is environmentally friendly.
