This paper reports on the investigation of the effect of lifting parameters on bending moment at the lower back. The experimental study has been conducted under varying load weights, horizontal location of load from L5/S1 and lifting technique (stoop, full squat and lifting device). The design of experiments approach using Taguchi’s orthogonal array was used. The level of importance of the parameters on bending moment has been determined using the analysis of variance (ANOVA). After implementing a lifting device 26-34 % reduction in bending moment at L5/S1 has been observed.
