A Battery-Powered Tool to Move Utility Manhole Covers: Field Data and Proof of Concept
A new tool was designed and fabricated for workers to remove and replace electric utility manhole and vault covers. This tool, which is portable and weighs 7.26 kg (16 lb.), employs a battery-powered electric motor to raise and lower the cover, reducing the manual force. The design was based on field observations and biomechanical measurements of utility workers who moved manhole covers. Biomechanical data from the pilot study reveal the tool’s potential to reduce risk of a back injury. Field observations and data demonstrate the proof of concept, and the design will be further developed.
期刊介绍：
Ergonomics in Design: The Quarterly of Human Factors Applications is intended to serve the needs of practicing human factors/ergonomics professionals who are concerned with the usability of products, systems, tools, and environments. It provides up-to-date demonstrations of the importance of HF/E principles in design and implementation. Articles, case studies, anecdotes, debates, and interviews focus on the way in which HF/E research and methods are applied in the design, development, prototyping, test and evaluation, training, and manufacturing processes of a product or system.
