ErgoExpo Webinar: Effective Ergonomic Design of Manual Material Handling Carts

ergoexpo darcor webinarJoin 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
