Ergonomic assessment in a material unloading station
Keywords:
Ergonomic evaluation, postural load, REBA, 3DSSPP.Abstract
This work was developed in a local company, in the station called "arm discharge", with the aim of determining the relationship of the design of the workplace with the muscular-skeletal complaints presented in the workers, and to know the level of postural risk to which they are exposed. An ergonomic evaluation was performed with the REBA method and the task was simulated through 3DSSPP® software. With the results obtained in the present evaluations, it was found that the level of risk for the arm discharge station according to REBA, requires a level of action 4 requiring an immediate containment which suggests that the workstation has ergonomic problems and is necessary the redesign of said station. The activities of placing tray with dolly material and placing tray with dolly material at midpoint, were simulated through 3DSSPP® biomechanical analysis software. It is concluded that in the design of this work area generates a high postural load on the back, arms, and wrists, so changes must be made to improve the worker's posture and correct his center of mass to a safe area.
