Abstract

Pallet jacks used in manual material handling jobs are commonly pulled behind the operator to allow full visibility, resulting in awkward shoulder extension and trunk rotation. In this laboratory study, we compared an alternative handle with a standard handle during use when traveling with the pallet jack behind the operator. Total oxygen consumption, usability, comfort, and preference were compared between the two handles. The results showed different advantages associated with each handle design, leading to the conclusion that a secondary handle, used in conjunction with a primary standard handle, may be a beneficial intervention for pallet jack use.
