In our last few posts we’ve been talking about the importance of ergonomics in creating both a safe and healthy work environment and the benefits that can provide to your business. Ergonomically-designed equipment decreases the frequency and severity of workplace injuries, medical costs and disability payments, and absenteeism, while increasing employee morale, efficiency and productivity, and profitability.
With so many benefits, it pays a company to invest in ergonomically-designed equipment, but how can you determine your ergonomic needs? DJ Products provides a useful Ergonomic Load Calculator on our website. The calculator is designed to estimate the amount of horizontal force necessary to move wheeled loads in various workplace environments.
Easy to use, our calculator takes you through a series of questions regarding floor condition, terrain, footing, equipment condition, equipment configuration, use of assembly line when applicable, and load weight to determine the required force to move an average load. A second series of questions factors in human performance qualifiers such as proposed worker, frequency and distance each load will be moved, whether loads are pushed or pulled, and handle height. Using mathematic formulas, a Human Performance Capability is calculated that provides an ergonomic estimate of the amount of force that a single worker should apply to move the load. Calculations are provided for both initiating and sustaining equipment motion. A comparison of the calculated equipment force to the ergonomic limit of force allows ergonomists, health and safety officers, and other professionals to accurately evaluate the ergonomic needs of a company.
The program also offers helpful suggestions that can be used to improve workplace safety. For example, an ergonomic evaluation of a manually-wheeled pull-cart might recommend a specific caster size to reduce initiation force or improve pivoting. It might recommend a maximum weight load for the equipment being evaluated. It is always recommended that ergonomic solutions be immediately implemented wherever force exceeds capacity to prevent worker injury.
