The main objective of this paper is to model a weightlifting process using JACK software and analyze the lifting process, in order to reduce the risk of lower back injuries for lifting tasks. As industrial engineering students our aim is to understand the hazards of lifting heavy objects in the work area and reduce the risk of having lower back problems in the future. For this purpose, a weightlifting competition more specifically “ergonomic weightlifting” in other words while you are lifting as much weight as possible you are considering your lower back area and lower back spinal forces during lifting tasks, are designed and performed. JACK software is used to create a human model that lifts weights. We followed the National Institute for Occupational Safety and Health (NIOSH), guidelines to prevent the lower back injuries that can occur while ergonomic weightlifting competition. This paper gives the detailed description of the ergonomic weightlifting competition and results of it.
