How much can ergonomics make a difference in productivity and preventing injury? A lot, it turns out. Since 2003, for example, Ford has reduced its assembly line injury rate by 70% by applying ergonomics research to assembly improvements and lift-assist technologies. In the past five years, Timken has cut its ergonomics risk factors each year by 20% by requiring three innovative improvements annually at each plant. These photos show how manufacturing companies are applying the latest ergonomic technology, culling approaches and technology from orthopedics, virtual reality, exercise physiology and the book of common sense.
