Abstract
Industrial carts require significant pushing/pulling forces causing postural discomfort to operators in shoulder, neck, lower back. The purpose of this study was to diminish postural uneasiness during the operation of the cart by modifying it. The modified cart includes a pelvis support with a waist belt, an increased handle height and all swivel wheels to scale down the discomfort levels in specific regions and assist with improved motion of the cart. After modification, the discomfort levels on shoulder, lower arms, mid back and lower back are significantly lesser. The results of this study indicate significant difference in discomfort levels and better maneuverability with the modified cart.
