Workshop Lean Pipe Workstation Layout Standard？

The arrangement of lean workbenches in the workshop must adhere to ergonomic, safety, efficiency, and production adaptability principles, with the following specific standards:

1. Basic Dimension Parameters

1. **Workbench Height**: For standing operations, it is recommended to be 780-850mm; for sitting operations, 750-780mm. An adjustable lifting mechanism (adjustable range: 650-900mm) can be installed. In heavy-duty machining scenarios, the height can be lowered to 700-750mm to reduce bending effort.
2. **Workbench Width**: For single-person operation ≤800mm, for dual-person facing operation ≥1000mm; recommended 600-800mm for precision tasks like electronic assembly, and 800-1200mm for mechanical processing.
3. Underfloor Space: Standing operation ≥650mm (including leg movement), sitting operation ≥500mm (adjustable to seat height), width ≥500mm to avoid obstruction.

II. Layout Principles
1. Process Principle: Arrange equipment according to the production sequence to minimize material handling distance.
2. Ergonomics: Tools are arranged in an arc (fan-shaped layout) for easy access within the wrist's range of motion.
3. Safety Principles: Reserve emergency exits, isolate hazardous equipment, and comply with OSHA safety distances.
4. 5S Management: Workbench zoning (inspection pending area, inspection completed area, non-conforming product area), with identification lines 10mm wide (solid blue lines).
