In the packing department, a worker stands sideways between the end of a conveyor and a pallet. The surface of the conveyor is 40 inches from the floor and the top of the pallet is 6 inches from the floor. As a box moves to the end of the conveyor, the worker twists 90 degrees to pick up the box, then twists 180 degrees in the opposite direction and sets the box down on the pallet. Each box is 12 inches on a side and weighs 25 lbs. Assume the worker moves five boxes per minute for an 8-hour shift. Using the NIOSH lifting equation, calculate RWL and LI. Redesign the task to improve it. What are the RWL and Ll now? Discuss your conclusions from the results of both tasks. (50 points, Show all work) a) Calculate the RWL and Ll. (15 points) b) Redesign the task to improve it. (15 points) c) Calculate the Redesign RWL and LI. (10 points) d) Discuss your conclusions from the results of both tasks.
