Goals of Workstation Design
• Optimize use of energy and thus maximize productivity
• Avoid musculo-skeletal problems
• Enhance safety
Key Issue-----
“Adjustability”
Principles of Work Design
• Determine work surface height by elbow height
• Adjust the work surface height based on the task being performed
• Provide a comfortable chair for the seated operator
• Provide adjustibility in the seat
Text: pp 187-200
Principles of Work Design(Contd)
• Encourage postural flexibility
• Provide antifatigue mats for standing operators
• Locate all tools & materials within normal working areas
• Fix locations for all tools & materials to permit the best sequence
Principles of Work Design(Contd)
• Use gravity bins and drop delivery to reduce reach and move times
• Arrange tools, controls and other components optimally to minimize motions
Guidelines for Workstation design
• Avoid static loads and fixed work postures• Reduce Musculoskeletal disorders
( CTD’s)• Set work height at 50 mm below elbows• Furnish every employee an adjustable chair• Use the feet as well as the hands
Ref.: Konz Text, Chp. 13
Guidelines for Workstation design (con’d)
• Use gravity, don’t oppose it• Conserve momentum• Use two-handed motions rather than one-handed
motions• Use parallel motions for eye control of two-
handed motions• Use rowing motions for two-handed motions
Ref.: Konz Text, Chp. 13
Guidelines for Workstation design (con’d)
• Pivot motions about elbow
• Use preferred hand
• Keep arm motions in normal work area
• Let the small person reach; let the large person fit
Ref.: Konz Text, Chp. 13
