山下製作所 List of Products and Services

We design and manufacture various types of platforms (operational platforms, walkways, stairs, handrails, ladders, etc.) tailored to our customers' requests, one by one. Using our unique methods, we supply bolt-joined platforms at high quality and low prices. We conduct everything from structural analysis and strength calculations to planning and design using 3D CAD, as well as detailed work (including the creation of installation drawings). Additionally, we can provide integrated manufacturing from primary processing linked with 3D CAD to assembly and painting. <Feature 1> Quality Improvement - Steel Structure Integrated Manufacturing System By converting data from 3D CAD software to each processing machine, parts are manufactured according to the drawings. Since welding is not performed, thermal distortion does not occur, allowing for the stable supply of products. <Feature 2> Reduction of Manufacturing Labor By using bolts in all factory assembly parts, we shorten the manufacturing period and can supply at a lower price. <Feature 3> Reduction of Installation Labor By using bolts in all installation parts on-site, we can reduce installation labor by eliminating welding and the associated curing work, as well as the grinding range during finishing painting. For more details, please download the PDF materials or feel free to contact us.

The types of platforms we handle are categorized into the following three types based on their uses: ■ Operation Platform A floor or walkway (including stairs, ladders, and handrails) for people to approach for the operation, inspection, and monitoring of manufacturing machinery, piping equipment, conveyors, tanks, etc. ■ Support Platform A framework for installing and supporting heavy objects such as machinery and equipment. ■ Piping and Duct Platform A framework for collectively supporting piping, ducts, cables, etc. For more details, please download the PDF document (What is a platform? Basic knowledge you should know) or feel free to contact us.

In various plants and factory facilities, numerous floors and walkways (including stairs, ladders, and handrails) are installed for people to gather for the operation, maintenance inspection, and monitoring of equipment, tanks, pumps, conveyors, manholes, piping valves, etc., regardless of whether they are indoors or outdoors. These operational platforms are typically constructed through welding during the factory fabrication and assembly work at the installation site of beams, columns, stairs, and handrails. However, the removal of welding thermal distortion and finishing work for painting often accompany this process, contributing to high costs. We would like to introduce a bolt-connected operational platform that can reduce welding labor, not only decreasing fabrication labor but also contributing to a reduction in assembly labor at the installation site. *Please download the PDF document (Product Technical Data: Bolt-Connected Operational Platform Pursuing Reduction in Fabrication and Installation Labor). By utilizing the general-purpose 3D software "TEKLA STRUCTURES," we conduct structural planning and verification of equipment operability, and after confirming the strength of each component, we expand it into factory fabrication drawings with the client's approval if necessary. We provide part processing drawings, product assembly drawings, installation drawings, 3D data, and various lists created from the 3D model. Please feel free to contact us with any details or questions.

We provide a comprehensive service from basic planning (foundation load calculations, structural analysis, strength calculations) to layout design using general-purpose 3D CAD (TEKLA STRUCTURES) and detailed work (installation and construction drawing creation) for structures that support piping, ducts, cables, and other equipment within various plants and factory facilities. If necessary, we also offer a complete package from design to product supply, including piping supports (such as spring hangers, pipe shoes, and saddles). By customizing "TEKLA STRUCTURES" in-house, we enhance the efficiency of design work, including automated placement of standardized products. The models created in 3D can be expanded into part processing drawings, assembly drawings, installation drawings, 3D data required by customers, and various lists. Data can also be exported to analysis software and various processing machines, contributing not only to design but also to improving manufacturing efficiency. *For more details, please refer to the PDF document (Technical Material: Engineering of Pipe Racks and Support Racks). Please feel free to contact us with any questions or for further information.

Please leave the design work related to steel structures such as frames to us. We utilize the general-purpose 3D software "TEKLA STRUCTURES" to conduct structural planning, confirm equipment operability, and after verifying the strength of each component, we will develop the factory production drawings with your approval if necessary. We provide part processing drawings, product assembly drawings, installation drawings, 3D data, and various lists created from the 3D model. *For more details, please refer to the PDF document (Reference Material: Integrated Design and Manufacturing System with Tekla Structures - Frames). If you have any questions or need further information, please feel free to contact us.

We would like to introduce our "bolt-joined operation platform" that can reduce both manufacturing and installation labor hours. In various plants and factory facilities, there are numerous floors and walkways installed for the purpose of operating, maintaining, inspecting, and monitoring equipment and tanks, both indoors and outdoors. These operation platforms are typically constructed using welding for assembly work, but this often involves the removal of welding thermal distortion and finishing work for painting, which contributes to high costs. Our company offers a "bolt-joined operation platform" that not only reduces welding labor hours but also contributes to a reduction in assembly labor hours at the installation site. By utilizing the general-purpose 3D software "TEKLA STRUCTURES," we conduct structural planning and verify equipment operability, and after confirming the strength of each component, we develop factory production drawings with the customer's approval if necessary. We also provide part processing drawings, product assembly drawings, installation drawings, 3D data, and various lists created from the 3D model. *For more details, please refer to the PDF materials or feel free to contact us.

We aim for a welding-free approach for various steel structures. ■ Operating platforms ■ Walkways and floors ■ Maintenance decks ■ Stairs ■ Ladders ■ Handrails and more. By considering the adoption of bolted connections for all member joints, including beams, columns, stairs, ladders, and handrails, we will achieve cost reduction. This will simplify assembly work and lead to a reduction in man-hours. Benefits of a welding-free approach: ■ No need for skilled craftsmanship (welders) ■ Elimination of thermal distortion and finishing work ■ No need for compliance with regulations (welding fumes) and more. *For more details, please refer to the PDF document (Product Technical Data: A bolted connection type operating platform pursuing reductions in manufacturing and installation man-hours). Using the general-purpose 3D software "TEKLA STRUCTURES," we will carry out structural planning, strength verification of each member, and detailed design. We will provide part drawings, assembly drawings, installation drawings, 3D data, and various lists created from the 3D model.
