WEARBALE SENSOR TECHNOLOGY: OBJECTIVE EVIDENCE TO SUPPORT DECISIONS

Woolworths were looking to reduce low back injuries due to manual handling of milk into display fridges. To do this, they were interested in implementing a new trolley called the “Rotocaster”.  In order to ensure the new trolley would improve on current manual handling practices, a ViSafe assessment was conducted to provide objective proof.

With a combination of video and movement data obtained from ViSafe, it was identified that the Rotocaster trolley would reduce forward bends (of greater than 20°) by 87%.  Furthermore, the data also identified a 21% reduction in time taken to complete the task using the Rotocaster.

The ViSafe assessment provided Woolworths with the objective evidence that investing in the self-supporting trolleys would not only significantly reduce the risk of injury, but also improve productivity.  It allowed management to move from what seemed like a good choice to a proven investment, that would drastically reduce the risk of injury for their workers.

As a result, Woolworths invested in 20 Rotocaster trolleys to trial in stores across Victoria and New South Wales, with the aim of a national rollout across their hundreds of locations.
