The "Spreader" is the solution to the concerns of customers who are struggling with "lifting containers" and "loading and unloading heavy goods." A spreader is a lifting device designed to safely and securely move containers, and our company offers four types of spreaders tailored to the size, length, and purpose of the containers. 〇 Container Lifting Spreader This lifting device uses a twist lock to grasp the container box without any mechanical power, ensuring safe and reliable container handling. 〇 Overheight Spreader This is a lifting device used in conjunction with the spreader of a gantry crane at port facilities. 〇 Overheight Attachment This is a lifting device used in conjunction with the spreader of a gantry crane at port facilities. 〇 Telescopic Overheight Attachment This attachment has a telescopic section that adjusts in length to accommodate different container types (20ft-40ft or 45ft). Please feel free to contact us for more details.

Since our establishment, we have developed (designed and manufactured) metal products using iron, aluminum, and stainless steel in various categories such as "architectural hardware," "civil engineering materials," "marine hardware," "temporary hardware," "logistics equipment," and "exteriors." In product development, we repeatedly conduct strength tests, including tensile tests, load tests, and drop tests, which are related to safety and security. Indeed, it is only by testing products to their limits that we can understand their capabilities. If the strength of a product can only be understood theoretically, it leaves a lingering sense of uncertainty. By testing, we can transform that uncertainty into a tangible form, meaning we can finish products that we can confidently sell. When you entrust us with your needs, we will resolve uncertainties and shape them into reality, supported by strength tests in our development assistance. Our company aims to create "one-of-a-kind manufacturing that ensures safety and security" by shaping our customers' needs. Please feel free to contact us for more details.

The "Telescopic Overheight Attachment" is an attachment whose long part can extend or retract according to the type of container box (20ft-40ft or 45ft). The connection method and twist lock operation are the same as those of the overheight attachment. Additionally, the telescoping mechanism is linked to the spreader on the gantry crane side. Each product generally conforms to the dimensions of ISO container boxes, but the specifications for leg length, lifting capacity, and self-weight vary depending on the height of the overheight attachment. For more details, please feel free to contact us.

The "Overheight Attachment" is a lifting device used in conjunction with the spreader of gantry cranes at port facilities. It is designed to grasp boxes containing cargo that exceeds the height of standard container boxes (8.6ft/9.6ft). The connection to the gantry crane's spreader is made using a connecting pin. Additionally, the twist lock operation of the overheight spreader is linked to the gantry crane's spreader. Therefore, if the gantry crane's spreader is locked, the attachment side will also be locked, and the unlocking will similarly be linked. Each product generally conforms to the dimensions of ISO container boxes, but the specifications for leg length, lifting capacity, and self-weight vary depending on the overheight. For more details, please contact us.

The "Overheight Spreader" is a lifting device used in conjunction with the mother spreaders of gantry cranes and transfer cranes at port facilities. It is designed to grasp open-top containers and flat-rack containers loaded with cargo that exceeds the height of standard container boxes (8.6ft/9.6ft). The connection between the mother spreader and the overheight spreader is made using the twist lock of the mother spreader, while the operation of the twist lock on the overheight spreader is performed manually using wire ropes arranged on the side. Each product generally conforms to the dimensions of ISO container boxes, but the specifications for leg length, lifting capacity, and self-weight vary depending on the overheight. For more details, please feel free to contact us.

The "Container Lifting Spreader" is designed to solve the concerns of customers who are struggling with "lifting containers" and "loading and unloading heavy cargo." We have a proven track record of supplying to a wide range of industries and companies, including container terminals, shipping companies, trading firms, and automobile manufacturers. 【Features】 ■ Labor-saving! The semi-automatic locking and unlocking mechanism, which operates through the repeated tensioning and loosening of the main wire, allows for container lifting without the use of mechanical power. Being semi-automatic also leads to reductions in labor costs and working hours. ■ Safety! The twist lock system, which cannot be removed under ISO regulations, ensures safety and security. Additionally, by suspending the container box's corner fittings (corner castings) at four points, safe and reliable cargo handling operations are possible. ■ Beyond containers... We will fully utilize our years of accumulated know-how and design capabilities to meet our customers' needs. We will solve the concerns of customers who are struggling with "loading and unloading heavy cargo, including containers." For more details, please contact us.

A power conditioner (power con) is a device that converts electricity generated by solar panels (modules) and Enefarm (home fuel cells) into a form that can be used in households. The electricity generated by solar panels is "direct current," and the power conditioner plays a role in converting this into "alternating current," making it usable electricity. To independently install a power conditioner on land, a dedicated structure is necessary. This is where the power con storage container, which utilizes a container as a building, comes into play. It is easy to install and move, and it offers excellent cost performance. Additionally, it is attractive that it qualifies for favorable treatment from the government, as it does not fall under the category of "storage tanks and other similar facilities" as defined in Article 2, Item 1 of the Building Standards Act. For the construction of solar power generation (especially mega-solar), please consider the power con storage container from Port Seiki Kogyo, which is easy to install, move, and dismantle, and is also environmentally friendly.

If the electricity generated by solar power systems cannot be stored, the surplus electricity is wasted. Therefore, various types of batteries such as lithium-ion, lead, and nickel-metal hydride are necessary for storing electricity, along with specialized structures for independently installing them on land. The storage container for batteries utilizes a container, making installation and relocation easy and offering excellent cost performance. Additionally, it is attractive that it qualifies for preferential treatment from the government, as it does not fall under the category of "storage tanks and other similar facilities" as defined in Article 2, Item 1 of the Building Standards Act. For the construction of solar power generation (especially mega-solar), please consider the battery storage container from Port Seiki Kogyo, which is easy to install, move, and dismantle, and is also environmentally friendly.

It is ideal for cost-effective product development in a short time since non-destructive testing can be conducted simultaneously with development. Magnetic particle testing is referred to in English as MT or MPT (Magnetic Particle Testing), and it can detect surface-opening defects (cracks) and subsurface defects by magnetizing the test specimen.
