Ergonomics
A poor match between operator and machine can cause physical discomfort and increases the chances of errors during operation.
Types and parts of machinery
- Cabs and operator stations on mobile harvesting machines
- Work stations on vegetable grading and potting lines
- Warning lights and displays on complex machines such as combines
Operator errors
- Fitting control boxes and displays incorrectly
- Failing to adjust workstation to suit individual needs
- Failure to respond to visual and audible warnings
Design points
- Provide sufficient adjustment and space to account for variation in body sizes.
- Consider the thermal comfort, noise and vibration of operator stations.
- Ensure controls are situated within suitable reach and are properly marked.
- Provide adequate space around controls so that they are easy to operate and their travel is consistent with the action to be performed.
- Provide automatic monitoring functions.
- Locate indicators and displays so that information can be detected and interpreted conveniently.
- Provide a means of changing work rate to suit individual operator needs.
Operator instructions and training
Instructions for using this type of machinery must include clear guidance on:
- Correct siting and installation of control systems
- Adjustment of the physical characteristics of the workstation.
