| Abstract |
Rough terrain crane operators working for a heavy construction hoisting company were surveyed by questionnaire to obtain basic data regarding their needs for safe and comfortable crane operation. Results revealed that nighttime shift operations often resulted in insufficient sleeping periods. Since drowsiness at work can be very dangerous, the lack of sleeping time should be addressed by rotating assigned operators on the nighttime shift. Half of the operators skipped breakfast or had it in the car on the way to work, thus posing the problem of an unbalanced diet. Regarding physical fatigue, stiff shoulders, probably resulting from operating the crane, were commonly reported. This may suggest that the right-side lever requires precise control and should be improved. 12 of the 16 operators surveyed reported mental fatigue due primarily to heavy traffic and working with other workers at the job site. |
