Detailed Installation Steps for Lean Tube Racks

Lean tube shelving (also known as rod-type shelving or plastic-coated tube shelving) is a modular storage equipment assembled from flexible lean tubes and various connectors, widely used in scenarios such as factory production lines and logistics centers. Its installation must follow strict procedures and standards to ensure structural stability and safe operation. Below are the detailed installation steps and key precautions.

I. Pre-Installation Preparation
1. Drawing and Technical Preparation: Before installation, thoroughly familiarize yourself with the shelf assembly drawings. For special or complex structures, develop a dedicated construction plan.
2. On-site Environment Verification: The installation site should have completed basic decoration, with related floor, trench, and other foundational works finished and concrete strength meeting or exceeding 75% of the design strength. All debris and waste on site must be cleared.
3. Component Inspection and Storage: After unpacking, verify all components (lean tubes, connectors, clamping screws, feet, tabletop panels, etc.) against the shipping list to ensure no shortages, damages, or deformations, and store them properly.
4. Tools and Instruments Preparation: Prepare installation tools and testing equipment that comply with national metrological regulations, ensuring their accuracy meets the installation requirements.

II. Core Assembly Steps and Principles
The assembly process should follow a clear sequence principle to ensure the stability and load-bearing capacity of the framework structure.
1. Main framework assembly sequence:
* Prioritize the assembly of support units: Follow the principle of "install side and base plates first, then connect the connecting rods" to establish a stable foundational support structure.
* Priority to load-bearing members: When connecting the framework, "install the load-bearing members first, then the connecting members.".
* From both ends toward the center: When installing connecting rods, it is advisable to "install the ends first and then the middle" to ensure even stress distribution across the entire frame.
2. Key Node Installation:
* Pillar verticality: When installing the pillars, ensure they are perpendicular to the ground to prevent deformation or damage to the shelves due to uneven stress distribution.
* Clamping head and screw fastening: All clamping heads and精益管 shall be installed in place according to design requirements, and ensure that every clamping head screw is tightened properly.
* Pipe Handling: When cutting precision tubes, care should be taken to avoid deformation. Load-bearing members should preferably use full-length pipes to maintain optimal strength.

3. Precautions During the Installation Process
1. Prohibit violent operations: Do not directly strike the精益管 or夹头 with a hard hammer during assembly.
2. Timely Verification and Feedback: During installation, continuous inspection against the drawings must be conducted. If discrepancies between the design drawings and on-site conditions are found, or if components are incorrect, they should be promptly reported and approved before any changes to the construction proceed.
3. Staged self-inspection: Conduct self-inspections during and after the installation process to ensure all components are correctly and securely installed.
4. Comply with technical specifications: The entire installation, construction, and acceptance process must adhere to relevant national or industry standards to ensure quality and safety.
