Overview
ISO 6682:1986/Amd 1:1989 is an important amendment to the original ISO 6682:1986 standard, published by the International Organization for Standardization (ISO). This amendment specifically addresses earth-moving machinery with a focus on the zones of comfort and reach for controls within the operator's cabin. It updates the ergonomic parameters to improve operator accessibility, comfort, and control positioning, enhancing safety and efficiency in earth-moving equipment operation.
The standard is developed by ISO Technical Committee ISO/TC 127, dedicated to earth-moving machinery, and reflects global considerations for human factors engineering. It ensures that control locations meet ergonomic requirements adapted for a broad range of operator anthropometrics.
Key Topics
- Zones of Comfort and Reach: The amendment revises the radii and positions related to the ergonomic zones where controls should be located for operator comfort and safety.
- Tables 5 and 6 Modifications: Changes include the introduction of notes clarifying coordinate systems and radii values for the centre of curvature points Ks1 and Ks2 related to control reach zones.
- Anthropometric Adjustments: Recognizes variability in operator leg lengths globally, referencing ISO 3411, recommending special adjustments in positioning to accommodate operators below the 5% leg length percentile.
- Ergonomic Parameters:
- Coordinates of special points within the operator's cabin are adjusted to better reflect comfort zones.
- Radii such as R3 and R6 are specifically noted with recommended values to refine comfort zones.
- Practical Notes: The amendment advises the incorporation of special adjustments to improve inclusivity for smaller operators, ensuring ergonomics standards adapt to diverse anthropometric data worldwide.
Applications
The ISO 6682:1986/Amd 1:1989 standard is applicable across the design, manufacturing, and evaluation phases of various types of earth-moving machinery, including:
- Excavators
- Bulldozers
- Loaders and Backhoes
- Graders and Scrapers
By adhering to this amendment, manufacturers can:
- Design operator cabins with optimized control layouts that reduce operator fatigue
- Enhance safety by ensuring controls remain within easy and natural reach
- Improve machine operation efficiency through ergonomic control placement
- Address global market requirements by adjusting designs for different operator anthropometrics
- Comply with international ergonomics and safety standards for construction and earth-moving machines
