Abstract [en]

It is often difficult to force obstacles with utility trucks. To facilitate this Yo-yo trucks have been developed and ergonomically evaluated. Three types of Yoyo utility trucks were compared with traditional ones. Subjective assessments, force measurements and photo documentation were used. The results show that the Yoyo trucks are experienced as easier to cross obstacles; lead to fewer jerks and are less strenuous. Further, the risks for sudden stops and dropping of the load decrease. The force to cross obstacles with the traditional trucks is between 34-142 % higher and significantly higher in all but one case. The conclusions are that Yoyo trucks are ergonomically advantageous, can be developed further and used in other applications.
