Join us for the next ErgoExpo Webinar
November 14, 2018 | 2 p.m. ET / 11 a.m. PT
Duration: 60 minutes
Produced by: National Ergonomics Conference & ErgoExpo
An increasing portion of manual material handling (MMH) involves pushing and pulling. In this ErgoExpo webinar, Yohann Printer and Tom Albin will discuss designing carts to keep manual operating forces within safe, recommended limits to reduce risk of injury and to facilitate operational efficiency. They will also cover a new clarification of the ISO 11228-2 force measurement protocol, which is intended to facilitate direct comparison of cart design factors’ effect on operating forces.
You will also learn about two systems for evaluating what percentage of the workforce is capable of exerting push and pull forces: the familiar psycho-physical-based Liberty Mutual Manual Materials Handling Tables and the more recent biomechanically-based tables developed at Ohio State University. Additionally, you will explore the importance of concurrently evaluating all the different types of force exertions encountered while handling carts; e.g., starting and stopping, sustaining movement, turning carts, and loading and unloading carts to determine acceptable exertion levels for the composite activity.
Cart design factors to be covered will include visibility, handle height, operating forces, caster selection and caster placement. Finally, you’ll hear case studies of the effectiveness of employing good ergonomics in cart design.
ErgoExpo Webinar takeaways
- Illustrate how cart design impacts back and shoulder injury risk during MMH tasks
- Use task analysis to understand MMH task requirements
- Optimize cart designs for both the task and the user
- Gain practical guidelines for cart design

Tom Albin is a licensed professional engineer (PE) and a certified professional ergonomist (CPE). He holds a PhD from the Technical University of Delft in the Netherlands. He is a fellow of the Human Factors and Ergonomics Society (HFES).
Currently the principal of High Plains Ergonomics Service, Tom has been engaged in ergonomics consulting since 1989. He has extensive experience as a researcher, a corporate ergonomist and as a product developer. He is active in the US and International Standards community, chairing the ANSI/HFES 100 computer workstation standard and serving as an accredited US expert on several ISO committees. He was Executive Director of the Office Ergonomics Research Committee from 2007 until retiring in 2018. He is a member of the Applied Ergonomics Society and is a member at large of the HFES’ executive council.
Tom’s consulting work has been principally concerned with physical ergonomics issues in office and industrial settings. Current projects deal with evaluation of injury risk during push and pull tasks and with applied anthropometry

Yohann Printer is an Ergonomic Design Engineer at Darcor Limited. He holds a Bachelor of Technology degree from McMaster University specializing in Automotive Technology.
Yohann has extensive experience in R&D, testing, and new product development of casters for ergonomic applications. His recent research was focused on caster tread materials and their contribution to a casters ergonomic performance. He has consulted globally on providing ergonomic caster solutions to industrial markets. He is focused on driving forward education on ergonomic benefits of proper caster selection in manual materials handling (MMH) applications.
